NEW RECORDS IN THE NEW ZEALAND :

A species of the Family Hemerobiidae, Boriom~ia maorica Tillyard 1923, previously thought to be an endemic species, has now been recognized as a widespread European species Wesmaelius sub- nebulosus (Stephens, 1836), and is presumably introduced. An undescribed Australian species has been found in New Zealand bringing the number of New Zealand species to five. Genus Wesmaelius Kriiger, 1922 Boriomyia Banks, 1905, Trans. Amer. Ent. Soc. 32: 36 (non Borio- myia Banks, 1904). Wesmaelius Kriiger, 1922, Stettin ent. Ztg. 83: 170. Kimminsia Killington, 1937, Monogr. British Neur. 2: 254.

The species long known as the endemic Boriomyia maorica Tillyard, 1923, in New Zealand, was first recognised as Boriomyia subnebulosa (Stephens, 1836) by B. Tjeder who examined New Zealand specimens sent to him by R. L. C. Pilgrim about 1967.

Following a request from Tjeder, I have examined the holo- type of Boriomyia maorica (Figs. 1-4) and compared it with descriptions, figures, and European specimens of Boriomyia sub- nebulosa, and find them to be conspecific. At the time the previous New Zealand Neuroptera list was written (Wise 1963) the status of species placed in Boriomyia was in question. Originally, Banks described the genus Boriom~ia(type species by original designation Hemerobius disjunctus Banks, 1897 (Banks 1897)) in a paper which was published in 1905 (Banks 1905) but he a!so listed two species separately, "Boriomyia fidelis Banks" (= Hemerobius fidelis Banks, 1897 (Banks 1897)) and "Boriomyia speciosus Banks" (= Hemerobius speciosus Banks, 1904 (Banks 1904a)), without generic description, in a paper which appelreJ earlier (Banks 1904b). Killington (1937, App. B) considered that Hemerobius fidelis Banks, 1897, and H. speciosus Banks, 1904, were not congeneric with the major group of species which had been considered to be congeneric with Boriomyia disjuncta (Banks, 1897) in the genus Boriomyia Banks, 1905 (not 1906 as recorcled by Killington). Killingion accepted the genus Boriomyia Banks, 1904, designating Hemerobius fidelis Banks as the type species, and erected the genus Kimminsia (type species by original designa- tion Hemerobious betulinus Strom, 1788) for the British species previously placed in Boriomyia Banks, 1905. At that time, Killing- ton (1937) was also accepting the genus Wesmaelius Kriiger, 1922 (Kliiger 1922), for some of the British species in this group, but Tjeder (1961) later synonymised Wesmaelius Kriiger, 1922, and Kimminsia Killington, 1937, with Boriomyia Banks, 1905. How- ever, there was still a difference of opinion between Neuroptero- logists on the validity of Boriomyia Banks, 1904, and Boriomyia Banks, 3.905. In order to resolve this question, Kimmins (1963) proposed validation of Boriomyia Banks, 1905, by the International Commission on Zoological Nomenclature. Amongst comments on this proposal by several authors (Carpenter 1964, MacLeod 1964, Eglin 1964, Tjeder 1964), there were expressions both for and against this proposal and also both for and against the synonymy of Wesmaelius with Boriomyia or Kimminsia. Tjeder (1964) suc- cinctly stated his reasons for considering Wesmaelius Kriiger, 1922, synonymous with Boriomyia Banks, 1905, and indicated that if the latter were suppressed then Wesmaelius would be the first valid name available and Kimminsia Killington, 1937, would become a synonym. The International Commission on Zoological Nomenclature (1965) did in fact refuse Kimmins' application and did accept Boriomyia Banks, 1904 (type species Hemerobius fidelis Banks, 1897, by sub- sequent designation, Killington, 1937). I am following Tjeder in accepting the genus Wesmaelius Kriiger, 1922 (type species by original designation Hemerobius concinnus Stephens, 1836), being the first available name by priority. Consequently, the species previously known in New Zealand as Boriomyia maorica Tillyard, 1923, is now found to be Wesmaelius aubnebulosus (Stephens, 1836). Sympherobius group The family Sympherobiidae and subfamily Sympherobiinae are

not generally accepted so the above group name, covering those genera with only 2 or 3 radial sectors in the forewing, is used here to separate the following unnamed species from the other Heme- robiidae. In April, 1971, a small lacewing taken by me at Ranui, near Henderson west of Auckland, was recognised as being of a species not kown in New Zealand. During a search, by beating vegetation, 15 days later, another specimen was collected. This attractive and unusual species was found to have only two radial sectors in the forewing (Fig. 5) and appeared to be closest

Riek, Australia, who subsequently advised (pers. comm.) that it is the same as a species known to occur from Canberra to southern Queensland, which is a new sp.ecies tentatively referred by him to a new genus (both unpublished). As Dr. Riek apparently has a description of the species in manuscript form, I have refrained from describing it here. New Zealand Hemerobiidae The New Zealand list as previously known (Wise 1963) now needs to be revised as follows: Drepanacra binocula (Newman, 1838). Australia, Lord Howe I, Norfolk I, Kermadec Is, New Zealand, Chatham Is. Micromus tasmaniae (Walker, 1860). Tasmania, Australia, New Hebrides, New Caledonia (Nakahara 1960), Norfolk I, Kerma- dec Is (Wise 1972), New Zealand, Chatham Is, Antipodes and Auckland Is (Wise 1971). Micromus bifasciatus Tillyard, 1923. New Zealand. Wesmaelius subnebulosus (Stephens, 1836). Europe (including England, Wales, Scotland and Ireland), Madeira, Turkestan, Siberia, New Zealand. Sympherobius group-1 species. Australia, New Zealand.

A STUDY ON THE SHEEP BOTFLY, OESTRUS OVIS (DIPTERA : OESTRIDAE) IN NEW ZEALAND P. R. KETTLE, Wallaceville Animal Research Station, Private Bag, Upper Hutt.

ABSTRACT The result of a survey of lamb and sheep heads to establish the ~easonalpattern, life history and geographic variations in incidence of Oestrus ovis Linnaeus within New Zeal~ndis reported.

INTRODUCTION Zumpt (1965) reported that "the nasal bot of sheep was already known to Redi in the 17th century and to other pre-Linnaen authors. Reaunler in 1734 published an illustrated paper on the 'mouche du ver du nez des moutons', and Linnaeus also made this fly a subject of a special paper, before he introduced it into the
