NejedH§ho, Hradec Kr<'ilove) In the present communication a number of new data on the distri­ bution of seven rare species of Orthoptera in Czechoslovakia is given besides the first documents on the distribution of Isophya brevipennis Br.-W. and Miramella ebneri carpathica C e j c h. in Poland. Fainily: T E T R I G I D A E Subfamily: Tetriginae Tetrix bolivari Sa u l c y, 1901 The only record on distribution of this species in Czechoslovakia [without locality indicated] we find in a paper of Mar an (1956: 12). In last years Dr. J. Mar an's and my joint endeavour to ascertain T. bolivari was successful: the species has been recorded at following six localities in Southern Slovakia and three in Southern Moravia: s. Slovakia: Sv. Maria, 22. VIII, 1960, 1 ~ (Cejchan lgt., call. Museum Hradec Kra­ love); Karnenny Most nad Hronern, VIII, 1952, 1 o", 2 !i! !i! (Mar an, lgt., call. Mus. Nat. Praha); Karnenin, 26. VI. 1959, 1 !i!

IX. 1953, 1 o", 1 !i! (Mar an lgt., coli. Mus. Nat. Praha). S. Moravia: Lednice, 1. VII. 1952, 2 !i! ~. [Mai'an lgt., coli. Mus. Nat. Praha), 10. VII. 1954, 2lo"o" [Cejchan lgt., call. A. Cejchan); Vl§stonice, 2. VII. 1952, l.!i! (Maran lgt., coli. Mus. Nat. Praha); Pouzdi'any, VIII. 1959, ,2 !i! ~ [Mai'an lgt., coli. Mus. Nat. Praha) . Tetrix bolivari in our country lives at more moist localities, often together with Tridactylus variegatus [La t r.) and with the related and very similar species Tetrix subulata (L.J being often misidentified with latter species. Thus its geographical distribution is insufficiently known until now. It does not occur more numerously at any locality hitherto known. All known finds show [see the map) that the species probably occurs sporadically on the whole territory of southern Slovakia and southeastern Mora via. 149 Family: ACRIDIDAE Subfamily: Catantopinae Miramella alpina alpina ( K o l l a r, 1833) f. microptera In the year 1960 Mar an (1960: 101) called attention -to the find of one female at Borkovicka blata near Veseli nad Luznici ( S. Bohemia). This was the first sure record on the distribution of Miramella alpina in Bohemia. M,. alpina reaches to Slovakia from Alps through Male Karpaty Mts. and there is distributed in the areae of Mala Fatra, Velka Fatra, High Tatra Mts. and further ranges of smaller mountains of Middle and Western Slovakia. In the east, in the area of Eastern Slovakian Carpathians, M. al­ pina is substituted by the related species M. ebneri, which is represented by the clean-cut subspecies carpathica C e j c h. In the west M. alpina penetrated only to Jeseniky Mts. in the Moravian-Silesian area. In higher situations (after Mar an about from 700 m elevation] of the mountain areae of Slovakia and Jeseniky Mts. M. a. alpina occurs in a more slender form with strongly abbreviated elytra (f. squamiptera). As cited in M a r a n ( 1960), the female specimen from Borkovice ex­ hibits the longer elytra (f. microptera] and agrees with the specimens from the lower situations, e. g. from Lower-Austrian Weissenbach near MOdling and from Kalfesburg ( G a l. v a g n i, 1954: 95). · In October 1962 I got from Mr. J. Niedl for the purpose of revising the five males and five females of Miramella alpina, which he collected near the municipality Chlum u Trebone at the forest clearing near the pond Medenice. The distance of the clearing from the municipality is about 2.5 km and its elevation is about 460 m. Locality is overgrown with the cranberries (Vaccinium vitis-idaea), here and there also with the bill­ berries (Vaccinium myrtillus) and with moist refuges of Drosera rotundi­ folia. Distance of the locality from the Czechoslovakian-Austrian boundary line is only 2 km. M. a. alpina is there distributed on the territory area about of 100 X 300 m. In the time between 1. VIII. 1962 and 20. VIII. 1962 the only four specimens have been found there. Maximal occurence was ascertained between 25. IX. and 10. X.. , when numerous specimens were found in copula. In latter time a number of about 120 specimens occured at the above mentioned locality. The most copious occurence was observed on the area 50 X 20 m on the outside of the clearing underneath the tall pinetrees (Pinus silvestris) with dense growth of Vaccinium myrtillus. Of the isolated distribution of M. alpina at Borkovicka blata M a r a n [ 1960) conjectures that M. alpina was ousted hither from the Alps in the last glacial period and thus it might be a glacial relict from this period. Contemporary find. of a numerous population of M. alpina near Chlum u Trebone, i. e. in neighbourhood of the Czechoslovakian-Austrian bound­ ary line would indicate the penetration of M. alpina from Austria to the Ti'eboii basin in much later time, it may be said, only in the recent period. Specimens from the environments of Chlum u Trebone exhibit longer elytra in both sexes. Elytra of the males reach to a half of the length 150 A Map of geographical distribution of Tetrix~ bolivari · ('~], in southern S1ovak!a and S. E. Mora via and Miramella a. O,lptna f . mtcroptera . fA..,] in southern Bohemia. of posterior femora; elytra of the f~males extend beyond the half of the fourth abdominal tergite. Thus I place these specimens to the form named as f. microptera although the comparative studies of the Bohemian and Slovakiai1 specimens from lower situations (e, g. from the environments of Spisska Nova Ves and Slovensky Raj j show the more distinct · dif· ferences between them. The Bohemian specimens have sbmewhat more slender bodyform, narrower e1ytra and in the males somewhat different I structure of the aedeagus . .. _ . Later i_nvestigations _of a more numerous material from Bohemia, Slovakia and Austria will show whether our forms may be separated as the inclependent geographical races.

In 1961 I have ascertained that M. e. car­ pathica i:; distributed only on the mountain ridge from Durkovec ( 1190 m 151 elevation) over Rabia Skala (1168 m) till to Czolo (1157 m). M. e. car­ pathica is distributed there in a narrow, nearly three kilometer long tract on both sides of the Czechoslovak-Polish state boundary line. The most numerous distribution is at Rabia Skala, where 3-4 specimens come to one quadrate meter. Miramella ebneri has not been ascertained in Poland untill now. N e w s p e c i e s to P o 1 a n d. Subfamily: Acridinae Chorthippus ·dichrous E v e r s m a n, 1859 In Czechoslovakia a rare species. First it was recorded by M a r a n (1953: 216) at the two localities in southeastern Slovakia (at Somotor and Sv. Maria). In the second half of August, 1960 we have ascertained this rare species near Leles (S. E. Slovakia) as rather numerous (2-3 speci­ mens on quadrate meter) in a joint discovery with Dr. W. Gtitz. Family: T ET T I G 0 N 11 D A E Subfamily: Phaneropterinae Phaneroptera falcata ( P o d a, 1761) In the territories of Southern Slovakia and Southern Moravia as a rather common xerothermous species. Fr.om the entomogeographical point of view its occurem:e in Eastern-Slovakian Carpathians is interest­ ing one. In 1961 it has been ascertained at following localities: Stak~In [300 m), 7. VIII. 1961, 3 c1c1 (Cejchan lgt., coli. A. Cejchan); Uli~ (260 m), 9. VIII. 1961, 2 .r!c1, 1 !i! (Cejchan lgt., con. A. Cejchan) and Nova Sedlica (370 m), 7. VIII. 1961, 1 lr! (Cejchan lgt., coil. A. Cejchan). · In Nova Sedlica there is the most northern limit of its geographical distribution in pzechoslovakia. Isophya brevipennis B runner-Watt en w y 1, 1878 This species was recently recorded from Czechoslovakia ( cfr. C e j­ c ha n, 1958a: 4). In 1961 it has been ascertained at further localities in area of Eastern-Slovakian Carpathians: Hrubky ( 1180 m), 8.
