OENEIS. By G. Weymer. 231 



about as in chry.vxs. The species appears only to occur in the Californian Sierra Nevada, especially near Lake 

 Tahoe. According to Edwards the egg is distinguished by the somewhat curved ribs on its surface. Concei'ning 

 larva and pupa nothing is known. 



0. noma Tlilg. (= hilda Quens., celaeno Hbn.) (vol. I, pi. 40c). According to Edward.s 3 examples noma. 

 of this Palearctic species were found in North Alaska, of which Staudinger had determined one that was sent 

 to him as probably a dark variet}^ of noma, the condition of the specimen leaving him in some doubt, noma 

 has on a brown ground a broad broMaiish yellow submarginal band across both wings, in which are placed 1 or 

 more eye-spots. The under surface is rather like that of chryxus, but the median band of the hindwing is darker 

 and more strongly dentate. Further observations as to the occurrence of this species in America would thus 

 be desirable. Cf. vol. I, p. 119. 



0. jutta Hbn. (= balder H. Schdff.) (50f). Another Palearctic species. The submarginal row of ochre- jutta. 

 yellow spots consists on the (J forewing of small round spots, in the $ of larger oval ones, the number of the 

 black dots in which varies from 1 — 4 on the forewing and from 1 — 2 on the hindwing. Beneath the entire hind- 

 wing and the apex of the forewing are grey, marbled with brown, the former with a greenish brown, dentate 

 band. — The surface of the egg bears irregular, in part forked, longitudinal ribs. The larva is light yellow- 

 gre}^ with ochreous longitudinal stripes and rows of black dots and small dashes on the dorsum and at the sides. 

 On grass, e. g. (in America) on luncus articulata. The pupa is whitish grey, at the abdominal end ochre-yellow. 

 ^Yhilst Holmgren says that in Europe jutta settles on pine-trunks, according to Fyles (in America) it always 

 sits on the gromid. When pursued it drops into the grass. It flies in June. In North America the species occurs 

 in Maine. Xova Scotia and the Hudson's Bay Territory. In addition it is found in North Europe and North 

 Asia. — alaskensis Hall, is a form of jutta with the wings more thinly scaled and transparent, and the spots alaskensia. 

 on the upper surface more indistinct. On the under surface the wings are uniformly marked with small spots 

 and streaks, so that on the hindwuag there is no trace of the darker band of jutta. From Alaska. June und July. 



0. uhleri Beak. (50 f). Above reddish yellow-brown with dark veins and narrow brown distal margin. uMeri. 

 Forewing with an eye-spot before the apex and sometimes with 1 or 2 black dots below it. On the hindwing 

 one or several black dots. Beneath the costal margin of the forewing and the entire hindwing are brownish 

 white ■«4th a number of broMTi transverse streaks, which are grouped into several narrow transverse stripes; 

 on the forewing are placed here 1 to 4 black spots, some of them with white pupils, on the hindwing a row 

 of indistinct dots. — The egg is chalk-white, with 19 or 20 longitudinal furrows and with the vertex pitted. 

 It hatches in about 10 days. The adult larva is about an inch long, stout, yellow-brown with grey dorsum and 

 light longitudinal lines. It pupates free, among grass-culms near to the ground; and the pupa is ochre-yellow, 

 darker on the dorsum. The butterily flies from the end of May until July, in Colorado. — varuna Ediv. (50f), vamna. 

 originally described as a separate species, is regarded by most authors as a northern form of uhleri, by some 

 even as a sjTionym. It is smaller, the colouring somewhat duller, the distal margin more broadly brown. On 

 the under surface of the hindwing there is sometimes a dark brown band before the middle. But the number 

 of eye-spots varies as in iMeri, Morrison for instance having sent me among several varuna from Montana 

 an example with 6 such spots on each surface of the hindwing. — According to Edwards the egg is chalk-white 

 and has 18 — 20 ribs, some of them incomplete. The larva varies from whitish green to dirty yellow-brown, 

 and is lighter on the back, with 3 rows of small black clashes and slate-grey subdorsal stripe. The pupa is ochre- 

 yellow, the -vnng-cases light yellow-green. The larva pupates in a sort of cocoon formed in the sand. From 

 Montana, North Dacota and the adjoining parts of Canada. — The preceding notes on the larva, pupa and 

 transformation do not agree well with one another. One might therefore suspect in the two forms two separate 

 species. Further investigations are needed to elucidate the matter. 



0. alberta Elw. (50 g). Forewing grey-brown above, in the $ strongly dusted with ochre-yellow, Avith alberta. 

 an ochre-yellow submarginal band in which are placed 1 — 3 black spots or ocelli. Hindwing with the band 

 more distinct, containing 1 eye-spot and 1 or 2 dots. Beneath the forewing is light brown-grey, towards 

 the apex whiti.sh, before this a short dark transverse band. Hindwing the same, with a broad, darker, irregular 

 transverse band across the middle, which is bordered with darker at the margins. — The larva is dark olive- 

 green or greenish slate-coloured with slightly lighter longitudinal stripes, on the back sometimes brown. The 

 pupa is grey-green with dark anterior margin. The butterfly flies on dry, stony slopes, resting on the bare ground. 

 It was discovered at Calgary in the province of Alberta (Canada). It flies in the middle of May. 



0. taygete Hhn. (= bootes Bdv.) (50 g). Above brown, the brownish oclire-yellow submarginal band taijgete. 

 in the ^ is only present on the hindwing and in both sexes lacks the black spots. Beneath similar to the figured 

 alberta in colouring and markings, but the dark median band on the hindwing is more strongly outcurved in 

 its anterior part, forming an acute angle basewards in the middle. From Labrador. 



0. subhyalina Curt. (= crambis Frr., also MoscJil., oeno Bdv., assimilis Btlr.) (50 g). Dirty ochre-yellow subhyalina. 

 to dark b^0Av^l, mostly with obscure cinnamon-brown or ochre-yellow band and ochre-yellow spots in the cells.
