Résumé

La premiere mention de Plecopteres du Quebec, par P. H. Gosse, date de 1840; on y cite 4 especes du comte de Sherbrooke. De 1876 a 1883, l'abbe Leon Provancher a compile une liste des especes du Que- bec; on peut y reconnaltre aujourd'hui 14 especes reparties dans 10 genres ainsi que des representants d'un autre genre. Le present tra- vail comprend 94 especes examinees par les auteurs et une espece citee dans la litterature. Une espece encore non decrite et une autre pro- bablement nouvelle (on n'en possede que des individus femelles) por- tent le total a 97. La plupart de ces especes appartiennent a une faune commune aux bassins hydrographiques des Grands Lacs et du Saint- Laurent; leur repartition geographique s'etend generalement du Min- nesota au Nouveau-Brunswick. Au sud du Saint-Laurent, on recon- n alit des elements faunistiques provenant de la region appalachienne; et, dans l'est du Quebec, on trouve des especes caracteristiques de la zone cotiere de l'Atl antique. Le nord du Quebec est colonise par les especes les plus robustes du bassin des Grands Lacs, ainsi que par deux especes endemiques; toutefois, la faune arctique typique, presente l'ouest de la Baie d'Hudson, y fait totalement defaut. •

Abstract

The first report on Quebec stoneflies, by P. H. Gosse, dates from 1840 and mentions 4 species from Sherbrooke County. From 1876 to 1883 l'abbe Leon Provancher listed the species from Quebec Pro- vince; he had 14 species now identifiable amongst 10 genera, and re- presentatives of one other genus. The present report includes 94 named species of which specimens have been seen by the authors, and one species cited from a published record. In addition there is one undescribed species, and another probably undescribed (only females

available), for a total of 97. Most of the species are of a group com- mon to much of the Great Lakes and St. Lawrence drainage, charac- teristically distributed from Minnesota to New Brunswick. South of the St. Lawrence River there is a strong Appalachian element, and in eastern Quebec there are a few species peculiar to the Atlantic coastal region. Northern Quebec contains some of the hardier repre- sentatives of the Great Lakes fauna and has two endemic species, but it lacks the characteristic arctic species found west of Hudson Bay.

Historical

Knowledge of the Quebec species of stoneflies dates perhaps from 1823, when the United States naturalist Thomas Say described 4 species that have since been identified — mainly by guesswork — with four that are now known to occur in the province. The first mention of specimens taken locally is in a book dated 1840, by a Mr. P.H. Gosse, described as « a series of conversations on the natural history of Lower Canada ». This book is divided into 26 chap- ters, each referring to a particular time of year. Actually the « conversations » refer not to Lower Canada in general, but to « the immediate neighbourhood of the village of Compton, situated on the river Coaticook, a tributary of the St. Francis, in the county of Sherbrooke.. . . » References to stoneflies are not very numerous, but they are worth quoting :

Page 79 (April 1st). c It belongs to a tribe which I call Water-flies, as I have never seen any of the species except in the immediate vici- nity of water. The species are numerous in this continent, forming the genus Semblis of Fabricius. This is an early kind, the clouded Water- fly (Perla Clio). Page 184 (June 1st). c 1 went out a day or two ago bush-beating among the willows, but the leaves were too young and small to af- ford me much success. I shook off a black Sawfly (Tenthredo), two green Waterflies (Perla Cydippe ?) Page 224 (June 20th). c . .. the delicate Green Waterfly (Perla Cy- dippe) flies about the margins of brooks and rivers; Page 231 (July 1st). c C. — A lad gave me, yesterday, a Water-fly of very large dimensions, measuring about three inches and three- fourths in spread of wing. It is of a dusky colour, and the nervures of the wings are of the same; its claims to notice are only its enormous size, as compared with other species of the genus, for it has no beauty. It is Pteronarcys Regalis. [page 232] F. — lhave taken a very large species Pteronarcys Proteus at Sherbrooke, near the junction of the Magog River with the St. Francis; but I have not any specimens now. It is not, however, near so large as yours, but resembles it in colour. 3,

Mr. Gosse was probably not familiar with Say's work, but he had the then very recent paper by Edward Newman (1838), and quotes the names of four of Newman's species. However Gosse's « clouded water-fly » had not KICKER ET AL: DISTRIBUTION OF QUEBEC STONEFLIES 1087 yet been described scientifically — it is obviously a species of Twniopteryx or Brachyptera — so his use of the name c/io is incorrect. The other three names may well be correctly used. The « green water-flies 2. belong to the genus and subgenus Alloperla, though unfortunately Newman's types of cydippe were females that cannot be definitely associated with a particular species among recent materials. Pteronarcys regalis Newman is now considered a synonym of Say's dorsata, and the smaller Pteronarcys might have been either proteus New- man or biloba Newman.

Following 1840 there was a gradual increase of stonefly information in North America, but for about 30 years almost none of it directly concerned Quebec. However, during the 1860's and 1870's the great Canadian naturalist l'abbe Leon Provancher was collecting insects assiduously at Portneuf and later at Cap Rouge, west of Quebec city. In 1871 he published in Le Naturaliste ca- nadien a list of Neuroptera taken in Quebec, which included 15 species of stone- flies arranged in 6 genera. In 1876 he described « une pluie d'insectes » that occurred on March 27 at Riviere-du-Loup, consisting of stoneflies of the species Capnia pygmaea. At the same time he mentioned the abundant occurence of this species and C. minima, apparently at Cap Rouge : these insects emerged at maple-syrup time and were often called « mouches a sucre » by the sugar- bush operators.

Later in 1876 Provancher's « Petite Faune entomologique du Canada ), that was appearing serially in the Naturaliste canadien, treated the family Per- lides. In 1878 a few « additions et corrections » were added, although for some groups the 1878 revision is less useful than the original treatment of 1876. The summary list of 1878 (p. 144) included 20 species, of which 8 bore names proposed by Provancher himself, and he had already synonymized several of his own 1876 names. In 1883 volume 2 of the Petite Faune was reprinted with some further additions and corrections'.

5. The 1883 treatment of Perlides in the Petite Faune is mainly a reprint of the 1876 material, but there are some interleaved pages, distinguished in numbering by the superscripts 2 and 3, that call attention to most of the additions and corrections pro- posed in 1878. Whether by inadvertence or design, the 1878 revision of Nemoura does not appear in 1883, the treatment of that genus being the same as in 1876. In addition, some pages of the 1883 text have been rearranged and two additional species are in- serted without any indication that they are appearing for the first time. These two are Perla chicoutimiensis (p. 75) and Taeniopteryx glacialis (p. 77), both treated below under Brachyptera glacialis. The 1883 summary list of species (p. 154) is identical with that of 1878 and does not include subsequent changes. The 1883 index (p. 161-162), however, is based on the 1883 text (including the older version of Nemoura). Anyone delving into this material should also be aware that page numbers 55-56 and 153-162 are used twice in the 1883 work: it is the second set of pages 55-56 and the first set of pages 153-162 that pertain to the c Nevropteres . 1088 LE NATURALISTE CANADIEN, VOL. 95, 1968

Provancher usually describes species as being e commun », « assez com- mun », « rare », etc., but only occasionally does he mention any exact locality where specimens were taken. Exceptions are the Allocapnia from Riviere-du- Loup mentioned above, and Brachyptera glacialis (Perla chicoutimiensis) that was found in quantity at Chicoutimi by the Rev. Mr. Huard. Also, of both Phasganophora capitata (Perla marginipes) and Acroneuria lycorias (Perla na- valis) it is said that « on la rencontre souvent sur les vaisseaux navigant sur le Fleuve entre Montreal et Quebec », and P. navalis « est particulierement com- mune aux Trois-Rivieres ». Thus while a great majority of Provancher's records probably apply to the vicinity of Cap Rouge or Portneuf, it is impossible to cite these localities definitely. Provancher's species were variously synonymized or ignored by subsequent writers, so that none appears in the 1925 Monograph by Needham and Claassen. Ricker (1952) studied the type specimens and some of the other specimens in the collection of the Musee Provincial du Quebec, and restored three of Pro- vancher's names to current usage. The best available modern identification of Provancher's species is as follows :

1. Pteronarcys dorsata Say Provancher describes this species under the names P. flavicornis Provancher 1876, P. rectus Provancher 1876 and P. regalis Newman. In 1878 flavicornis and rectus were synonymized with regalis, but in 1883 rectus was revived again. Our view is that the 1878 treatment was the correct one; however re- galis has since been synonymized with dorsata Say.

2. Pteronarcys biloba Newman The species P. bicarinatus Provancher 1876, as well as P. pictetii Hagen of Provancher 1876, were both synonymized with biloba by Provancher (1878, 1883).

3. Taeniopteryx nivalis Fitch T. maura Pictet of Provancher (1878, 1883) is most likely to be nivalis, the abundant species near Quebec; at any rate niaura, as defined by Ricker and Ross (1968), has not been taken recently in this region. The Taeniopteryx fasciata Burmeister of Provancher (1876) may also be nivalis, since the for- mer species (now Brachyptera fasciata) has been taken recently only in south- western Quebec, and there rarely.

4. Brachyptera glacialis Newport Taeniopteryx glacialis is listed on page 78 of the 1883 version of the Petite Faune; but on page 7e it is said to be the male of T. maura. Similarly Perla chicoutimiensis n. sp. appears first on page 75 of the same, while on page 723 it is said to be « tres probablement une variete du Taeniopterix maura, Burm. However the type of chicoutimiensis is definitely a female of glacialis New- port (Ricker, 1952). RICKER ET AL: DISTRIBUTION OF QUEBEC STONEFLIES 1089

5. Nemoura nigritta Provancher 1876 This species is abundant in the Quebec city region to-day. Three other species of Nemoura are listed by Provancher (1876); of these Nemoura albidipennis Walker is represented in recent material from this region by only one speci- men (from the Island of Orleans), while Nemoura completa Walker and Nemoura perfecta Walker are known in Quebec only from farther west or south. In 1878 Provancher revised his earlier treatment of Nemoura, proposing a new name (incerta) that must be considered a nomen nudum. In this treat- ment nigritta was synonymized with perfecta Walker, but the type of nigritta shows that the species involved is the one subsequently described as vettosa Banks, and long known under that name (Ricker, 1952). Like other entomo- logists of the time, Provancher did not have optical equipment adequate to observe clearly the distinguishing characters on these small species.

6. Leuctra tenella Provancher 1878 Provancher substituted this name for the tenuis Pictet of his 1876 paper, and the type specimen shows that the species involved is the one later described as hamula Claassen (Ricker, 1952).

7. Leuctra terruginea Walker Provancher (1877) proposed the name brunnea to replace his ferruginea of 1876, but no new description was given and the type cannot be distinguished from ferruginea, so brunnea must be regarded as a nomen nudum.

8. Allocapnia minima Newport

9. Allocapnia pygmaea Burmeister This species and the last were both reported by Provancher (1876 a, b), in the genus Capnia of course. Both are common in the Quebec region to-day, but no Provancher specimens have been checked recently. The name necydaloides Pic- tet was substituted for pygmaea by Provancher (1878), but modern usage ap- plies the older name pygmaea to the most abundant species of eastern Canada.

10. lsogenus olivaceus Walker Described under the name Perla sulcata Provancher 1876, but later erro- neously synonymized with frorttalis Newman (Provancher, 1878, p. 144). The synonymy with olivaceus is by Ricker (1952).

I I. Isoperla sp. Provancher lists Perla bilineata Say, but we cannot be sure what species he had.

12. Alloperla (s.s.) sp. Provancher (1876) lists A. severa Hagen (a western species), and Isopteryx cydippe Newman, the latter emended to Isopteryx nana Hagen [really Walsh] 1090 LE NATURALISTE CANADIEN, VOL. 95, 1968

in 1878. One or both of these records is most likely to be a species of Alloperla, but it is impossible to know which.

13. Alloperla naica Provancher

This species, rather rare in the region of Quebec city to-day, has been iden- tified by the type specimen, and the name precedes novascotiana Needham and Claassen (Ricker, 1952).

14. Acroneuria abnormis Newman

Listed by Provancher (1876) under the name Perla abnormis, but this was changed to P. arida Hagen in 1878. However arida is a more southern species. while abnormis is common in the Quebec region.

15. Acroneuria lycorias Newman Both Perla navalis Provancher 1876 and P. riparia Provancher 1876 have been synonymized with A. lycorias, by Needham and Claassen (1922). Perla que- becensis Provancher 1876 is another species that may belong in A croneuria; it was synonymized with the Mississippi valley species Acroneuria ruralis Hagen by Needham and Claassen (1922), but sketches of the type made about 1940 by Dr. T. H. Frison do not suggest this. P. quebecensis is probably one of the two Acroneuria species above, or possibly Paragnetina immarginata.

16. Phasganophora capitata Pictet

Reported as Perla hieroglyph/ca Provancher 1876 and P. marginipes Provan- cher 1876; the latter species was synonymized by Provancher (1878, 1883) with P. flavescens Walsh, itself a synonym of capitata.

In summary, we can be reasonably sure that Provancher had 11 genera of stoneflies, and 14 species can be identified with fair certainty. For three of these species Provancher's name is the first one available.

Following Provancher, occasional specimens of Quebec stoneflies have been recorded in general works. We may mention the 1925 Monograph by J. G. Needham and P. W. Claassen, and papers by Samal (1933), Frison (1942), Ricker (1935a, b, 1944, 1948, 1952, 1964, 1965), Brinck (1958), Nebeker (1967) and Ross et al. (1967). There is also the study of the wings of Allocapnia pygmaea made by Professor A. Willey of McGill University, from collections made « beside a small unnamed river in the lower Laurentians, about 50 miles to the northward of Montreal » (Willey, 1936). A general list of species and localities was prepared by Ricker during the middle 1940's, but it was never published; its records have been reviewed and incorporated into the present paper.

Collectors and Collections

The principal insect collections containing the specimens reported upon here are the following :

Canadian National Collection, Entomology Research Institute, Ottawa. Departement des Sciences Biologiques, Universite de Montreal, Mont- real, Quebec. Illinois Natural History Survey, Urbana, Illinois. Royal Ontario Museum, Toronto, Ontario.

In addition, some specimens are in the private collections of Peter Harper, W. E. Ricker and J. R. Coleman.

We present below a synopsis of the collecting activity and the names of many of the collectors who have worked in various parts of Quebec. Not associated with any special region is J. I. Beaulne, who collected in 1915 at Hull, Lanoraie, Montreal and Ste. Agathe.

EASTERN TOWNSHIPS This name is applied to the group of small counties south and east of Montreal and extending some distance down the St. Lawrence River. Near the river the « Monteregian Hills 2, stumps of ancient volcanoes, rise indivi- dually from the flood-plain. Once of these, Mont St. Hilaire in Rouville County, has been the subject of an intensive study of aquatic insects by Mrs. Rosemary MacKay (MS 1967). Most attention was given to West Creek, the principal tributary of Lac Hertel, and to the outlet stream from the same lake.

Farther south and east the Townships become rather consistently hilly, being in fact the northern end of the Appalachian mountain system. During the 1920's collectors from the Entomological Branch spent several summers in the region, and obtained records of a number of species not found elsewhere in Quebec. In Huntingdon County, Covey Hill was collected by C. H. Curran and G. S. Walley, Hemmingford by G. H. Hammond and C. E. Petch. Brome County, famous for its ducklings, is also distinguished by the entomological activity of J. A. Adams, G. H. Fisk, F. P. Ide, L. J. Milne and G. S. Walley during the late 1920's; this was supplemented by some work near Glen Sutton by W. E. Ricker in 1964.

GATINEAU REGION It is natural that entomologists employed by the Department of Agriculture in Ottawa should have spent considerable time in the hilly and scenic region 1092 LE NATURALISTE CANADIEN, VOL. 95, 1968 immediately north of them — comprising Hull and Gatineau Counties. A list of collectors would be almost a complete roster of employees of the former Entomological Branch (EB) and present Division of Systematic Entomology of the Entomology Research Institute (ERI). We may mention particularly W. J. Brown, C. H. Curran, T. N. Freeman, Arthur Gibson, S. D. Hicks, F. P. Ide, R. Lambert, J. McDunnough, C. H. Mann, J.E.H. Martin, L. J. Milne, D. R. Oliver, Raymond Ozbum, 0. Peck, H. L. Viereck, J. R. Vockeroth and G. S. Walley. Not directly associated with this branch of government is the intensive work done near Masham Mills and Wakefield by F. P. Ide and G. E. Bucher during the middle 1930's, and the collections made more or less weekly in Gatineau Park by W. E. Ricker in the spring of 1964.

Collecting trips into adjacent counties were also made from Ottawa by EB and ERI personnel. Most of these were done in warm weather, but an ex- cursion specially to collect the « winter » stoneflies was made in 1965 by J.E.H. Martin and J. F. McAlpine.

Some sites of special interest are as follows :

Camp Fortune, Gatineau Park. A ski bowl drained by a small stream that flows into Fortune Creek. Fortune Creek, Gatineau Park. Systematic collecting was done near the parking lot at the old Ridge Road in 1964. Kingsmere, Gatineau Park. The former Mackenzie King estate. One collecting spot was the stream draining a small lake on the site. Lusk Creek, near Luskville, 15 miles WNW of Hull, via Road 8. A small creek with a scenic falls; a popular picnic spot. Masham Mills. In 1935 Dr. F. P. Ide of the University of Toronto made systematic collections and rearings of aquatics at several stations in the Lapeche River and tributaries, 20 miles NW of Hull, via Road 11. McDonald Creek, Gatineau Park. A small but remarkably productive stream that cas- cades into Meach Lake from the south; visited regularly in 1964.

ILE D'ORLEANS

During 1954-59 the Reverend Rene Malouin collected intensively on the Island of Orleans, including both nymphs and adults, the results being reported in this paper for the first time. The streams where stoneflies were taken are located as shown below; the specimens are now in the Canadian National Collection.

Ruisseau Asselin: Crossing South Road five miles east of Bridge Road or three miles from Route des Pretres. Ruisseau des Camps: Crossing South Road 2.65 miles west of Bridge Road and Orleans avenue at two points. BICKER ET AL: DISTRIBUTION OF QUEBEC STONEFLIES 1093

Riviere Dauphine: Crossing Ste-Famille Road 2.7 miles south of North Road. This river runs towards the east. Ruisseau Gosselin: The nearest creek from St-Jean Church, on South Road. Ruisseau Guerard: Crossing North Road 13.9 miles east of Bridge Road. Riviere Lafleur: Crossing South Road 8.5 miles east of Bridge Road. Ruisseau Laverdiere: Crossing South Road 8 miles east of Bridge Road. Ruisseau Lemelin: Crossing North Road 8 miles east of Bridge Road; deeply em- banked stream. Ruisseau Maheux: Crossing South Road, 7 miles east of Bridge Road. Riviere du Moulin: Crossing North Road at the end of Orleans Island, 16.8 miles east of Bridge Road and 2.1 miles from St-Francois Church. Ruisseau Plante: Crossing North Road, 0.4 miles west of Bridge Road. This creek is crossing also Bridge Road 0.5 miles south of North Road. Riviere au Pot-au-Beurre: Crossing North Road 5.3 miles east of Bridge Road. Ruisseau Pouliot: Crossing South Road 7.5 miles east of Bridge Road. Ruisseau Ste-Famille: Crossing Ste-Famille Road 1.7 miles south of North Road. Ste- Famille Road crosses Orleans Island perpendicularly at its widest point, 9.9 miles from Bridge Road on northern section. Ruisseau St-Joseph: Running along the western side of Ste-Famille Road and crossing it to fall into Dauphin River. Ruisseau St-Patrice: Crossing South Road 1.8 miles east of Bridge Road. Deeply em- banked stream running southerly. Ruisseau Ste-Petronille: Crossing South Road, 0.2 mile west of Orlean avenue as well as Orleans avenue itself near its south end.

NORTH SHORE OF THE GULF OF ST. LAWRENCE (Saguenay Co.) Starting early in the century, occasional visitors to the region east of the Saguenay River brought back a few stoneflies. Among them are specimens from Godbout by Professor E. M. Walker of the University of Toronto in 1918, and from Matamek and Moisie Bay by Professor Eidmann of Hanover in 1931. The latter gave his material to Dr. J. Samal of Prague, who described two new species later synonymized with Pteronarcys dorsata and Acroneuria abnormis respectively (Samal, 1933). The north shore region was visited by W. J. Brown in 19290 and 1930; collections were made at Baie-de-la-Trinite (Trinity Bay — 49.4 N, 67.3 W), Riviere-au-Tonnerre (Thunder River — 50.3° N, 64.8° W), Lake Island (50.2° N, 60.1° W), Mutton Bay (50.8° N, 59.0° W) and partic- ularly at Bradore Bay (51.5° N, 57.2° W) near the Strait of Belle Isle. More recently Gilles Shooner of the Universite de Montreal spent the summer of 1962 at the Nabisipi River (50.2° N, 62.2° W) and collected extensively.

PARC DU MONT TREMBLANT The late Frere Adrien Robert of the Universite de Montreal collected assiduously in the southern part of the Park during 1954-62, working from the Station Biologique du Mont Tremblant (SBMT). His collections have been 1094 LE NATURALISTE CANADIEN, VOL. 95, 1968 made available to us by Mme Monique Coulloudon of the Universite de Mont- real. Some of the specimens are labelled simply as coming from the Park; others are from definite localities, as follows :

Riviere du Diable: Between Grand-Lac Monroe and Petit-Lac Monroe. In 1958 emer- gence traps were maintained in this river (Robert, 1958). Ruisseau des AuInes: A stream entering Grand-Lac Monroe from the east, 1.5 miles north of SBMT. Ruisseau Beattie. Ruisseau des trables: Enters Riviere du Diable from the east, a little north of SBMT. Ruisseau des Femmes: A small brook just south of SBMT, flowing north from the tiny Lac des Femmes and entering Petit-Lac Monroe from the east. Ruisseau des Ormes. Ruisseau i l'Ours: Enters Riviere du Diable from the west, between Lac Chat and Petit-Lac Monroe, 1 mile SW of SBMT. Lac Brochet: 4 miles SW of SBMT.

REGION OF QUEBEC CITY The pioneer activity of the Abbe Provancher was discussed earlier.

In 1958 and 1959 the Reverend Rene Malouin collected in the Mont- morency River and a number of smaller streams north and east of the city. These included streams along the road to the village of Laval (here called « Rou- te Laval »; the Ruisseaux Barriere, Bride, Goudreault and Rouge 15 to 25 miles north of Laval; streams along the road east to Ste. Anne de Beaupre Laurentides collections were made from Lac Jupiter and Lac Lille, from the Riviere et Lac Jacques Cartier, and from the Ruisseau de la rete. He also visited several localities south of the St. Lawrence within 50 miles of Quebec, as follows:

Riviere St. Nicolas: 6 miles SW of Quebec on Route 3, in Levis County. Riviere St. Gervais: At the village of St. Gervais in Bellechasse County. Lac Trois Saumons: Near the village of Trois Saumons in l'Islet County.

In 1966 J.E.H. Martin made an early spring trip down the St. Lawrence, collecting en route and along several lateral highways in Champlain, Laviolette, Portneuf, Quebec, Montmorency, Charlevoix and Chicoutimi Counties.

SOUTHERN LAURENTIAN HIGHLANDS The skiing region northwest of Montreal is traversed by Highway No. 11, which continues on to Mont Tremblant Park and northward. A number of ento- mologists have collected along the lower part of this route, especially from St. Je- FUCKER ET AL: DISTRIBUTION OF QUEBEC STONEFLIES 1095 rome to Ste. Agathe. In 1963 Frere Adrien Robert was made Director of the Sta- tion de Biologie de l'Universite de Montreal (SBUM), situated in a tract of land 6 miles from the village of St. Hippolyte de Kilkenny in Terrebonne County. In 1964 he set out some rearing cages in an unnamed brook that traverses the Station's property. These were tended by a student, Louise Venne, whose name appears on some of the specimens obtained. In 1966 Peter Harper made an in- tensive study of stoneflies in the same stream (Harper, MS 1967), and he col- lected in the same region again in 1967. All these records are listed as SBUM, in Terrebonne County. Specimens are in the collections of the Universite de Montreal and of Peter Harper.

TEMISCAMINGUE AND ABITIBI In 1939 F. P. Ide reared aquatic insects near Laniel and the town of Te- miscamingue. Other collections have been made in that county by H. S. Fleming in 1932-35, and by J.E.H. Martin and J. F. McAlpine in 1965.

A number of specimens labelled « Abitibi region collected by a Dr. Cook in 1915 and 1916, are in the United States National Museum and were studied by Ricker (1944).

UNGAVA Stonefly records from northern Canada were summarized about 25 years ago by Ricker (1944). These included a small number of records from northern Quebec.

During and after World War II visitors and residents in the northern parts of Canada became far more numerous, and they were greeted enthusiastically by the swarms of biting insects for which these regions are famous. This pro- vided one impetus for establishing a Northern Insect Survey (NIS) in the Ento- mology Research Institute, Ottawa, which sampled both biting and peaceful insects at about 50 sites. Of the sites in northern Quebec, twelve produced stone- flies, so that, together with the material obtained by two other recent collecting parties, our knowledge of the fauna in this great region is now quite respectable.

Lac Aigneau, 57.3° N, 70.4° W. Collections were made by D. R. Oliver in 1955 (NIS). Burnt Creek (Shefferville), 54.9° N, 67.0° W. Collections made by the NIS in 1948. Fort Chimo, 58.2° N, 68.3° W. Collections by R. H. MacLeod and H. N. Smith in 1948 (NIS). Eastmain River, east side of James Bay, 52.2° N, 78.5° W. Collections made August 1-14, 1934, by R. C. McDonald are in the CNC (Ricker, 1944). Great Whale River, east side of Hudson Bay, 55.3° N, 77.4° W. Collections by J. R. Vockeroth in 1949 (NIS). 1096 LE NATURALISTE CANADIEN, VOL. 95, 1968

Indian House Lake, 56° N, 64.7° W. Collections by R. Coyles and W. R. Richards in 1954 (NIS). Koksoak River and tributaries near 57.8° N, 69.0 W. Collections by J. D. Hynes in 1965 and by J. R.

Nomenclature and Zoogeography

The species names employed are those of lilies' (1966) check list, with one exception. Generic usage, however, generally follows the more comprehen- sive pattern that has usually been employed in recent North American stonefly papers. Subgenera are indicated where appropriate (these are usually treated as genera by lilies).

A review of the distribution patterns of Canadian stoneflies was presented by Ricker (MS 1963, 1964), including maps for selected species. Ross et al. (1967) have published maps for 3 species of Allocapnia. The new records presented in the present paper provide interesting extensions of range of a number of species. Comments concerning this are made in some instances, but a general discussion of zoogeography would be out of place.

One general observation concerns the role that Hudson Bay has played in stonefly distribution. This body of water acted as a barrier to the eastward move- ment of four tundra and taiga species, Nemoura arctica, Capnia nearctica, Diura bicaudata and Isoperla decolorata, that invaded Mackenzie and Keewatin follow- ing the Wisconsin glaciation, evidently from the unglaciated parts of Alaska or Siberia. Of these, Capnia nearctica is restricted to treeless tundra and alpine regions. It has reached Baffin Island but did not cross Hudson Strait, on whose southern shore is found the endemic Capnia sugluka, a tiny species of uncertain relationships. Nemoura arctica and Isoperla decolorata both extend down into BICKER ET AL: DISTRIBUTION OF QUEBEC STONEFLIES 1097 the forested region west of Hudson Bay; their absence from Quebec has per- mitted the related temperate-zone species Nemoura trispinosa and Isoperla bili- neata to move far to the north. Similarly, Isogenus olivaceus occurs north to the Koksoak River, but whether this can be related to the absence of Diura bi- caudata is more questionable. A species of western (Cordilleran) origin that has recently entered Quebec is Claassenia sabulosa: there is one record from the east side of James Bay. Other species of western relationships include Capnia vernalis, C. labradora, C. mani- toba, Brachyptera pacifica, Paraleuctra sara and Nemoura (Zapada) sp., but there is as yet no clear evidence whether these moved east before or after the most recent glaciation. A majority of Quebec stoneflies belong to a « Great Lakes-St. Lawrence ) group of species, characteristically distributed from Minnesota to New Bruns- wick or Nova Scotia, and south to northern Illinois, Indiana and Ohio, through New York, northern Pennsylvania and the New England states. Finally, there is a large Appalachian element in the fauna, especially south of the St. Lawrence River, consisting mostly of species that are abundant in the adjacent mountains of New York and New Hampshire and, in some cases, south to northern Georgia. These are species that are rare or absent from Ontario and south of the Great Lakes. They include Pteronarcys biloba, P. proteus, Pelto- perla arcuata, P. maria, Brachyptera rossi, Nemoura nigritta, N. wui, N. com- plexa, N. prolongata, N. similis, Leuctra triloba, Allocapnia nivicola, A. pechu- mani, Isogenus hastatus, lsoperla slossonae, Alloperla chloris, A. idei, A. late- rails, Acroneuria arenosa and Paragnetina immarginata. A smaller group of species is more characteristic of the eastern seaboard: Isogenus hansoni, Isoperla holochlora, Alloperla voinae, A. naica and Hastaperla orpha.

Distribution Records

The locality records are grouped by geographical areas, primarily the counties, but with a few exceptions:

(a) The Laurentides, Mont Tremblant and La Verendrye parks are sometimes cited. These cut across county boundaries and it is sometimes impossible to know in which county a specimen was taken.

(b) Two islands are used as geographical markers: Anticosti (Saguenay Co.) and Ile d'Orleans (Montmorency Co.). In addition, Montreal, as a primary heading, re- fers to Montreal Island rather than the city. (The Island is divided between two counties: Hocbelega and Jacques Cartier.) « Quebec 2) refers to the county rather than the city.

(c) The old name Ungava is used for the northern part of Quebec; this includes Mis- tassini County and all the regions northward. Sites in this great area were identified above by latitude and longitude. 1098 LE NATURALISTE CANADIEN, VOL. 95, 1968

Paraleuctra sara belongs in an otherwise western genus, and the name sara has been applied to western as well as eastern specimens: for example by Frison (1942) and Ricker (1964). However Hanson's (1962) careful study shows that eastern sara are different from all western specimens. RICKER ET AL: DISTRIBUTION OF QUEBEC STONEFLIES 1107

This species has been confused with I. bilineata. Study of the type series shows that the male from Mt. Washington, now in alcohol and labelled Type 2,, is generaly similar to the description given by Needham and Cla- assen (1925). (Two paratypes, from Franconia, N.H., are I. lata Frison.) The numerous Quebec specimens show a distinctive pattern of sclerites on the aedeagus: a distal very sharp sclerite shaped like a very broad arrowhead, which is usually visible through the cuticle of the 9th sternite; farther forward there is a median flat plate with darker central stripe, but this is less fre- quently visible without dissection. The colour pattern of the nymph is practi- cally identical with that of I. richardsoni (Frison, 1935, p. 458), but there may be a small difference in the shape of the lacinia.

Recorded from « Quebec » by Needham and Claassen (1925). Although we have seen no recent material, there is every likelihood this species occurs in the province; it has been taken in the Jacquet River on the south side of the Baie des Chaleurs (Ricker, 1948).
