238 EREBIA. By O. Weymeb. 



discoUhilis. E. discoidalis Kirhy (51 e). Above dark brown, the distal half of the forewing red-brown, the two cohmrs 



shading into one another; an obscure black eye-spot with whitish pu])il l)efore tiie aj^ex. Beneath the forewing 

 is red-brown, the margins striated with dark brown. Basal half of the hindwing brown, distal half grey, the 

 whole with darker striation. From Hud.son's Bay. Also occurs in Siberia, cf. vol. I, p. 111. 



fasciata. E. fasciata Bllr. (vol. I, pi. 35 e). Above brown, forewing distally red-brown as in discoidalis. Beneath 



the forewing is rust-coloured, whitish at the apex, with 3 brown bands, namely a basal, a median and a 

 marginal. The median band is undidate and at the costa broader; all these are bordered with rust-colour. 

 Hindwing whitish grey, with 3 similar, but red-brown liands, the middle one dentate at both sides. 51 — 5,S mm. 

 Localities: arctic North America. East Siberia. Cf. vol. I, p. 103. 



rossii. E. rossii Curt. Dai'k brown, with the fringes somewhat lighter. Forewing before the a])ex with red- 



brown s])ot, in which are placed 2 black dots. Sometimes below these 2 smaller red-brown spots, each with 

 a black dot. On the hindwing sometimes three similar spots with indistinct dots. Beneath the forewing is 

 red-brown with dark brown margins and sometimes with white-pupilled eye-spots. Hindwing dark bi'own, 

 dusted with whitish grey, with obscure darker median band, before the discocellular a wliite spot and beyond 

 it, before the distal margin, 2 or 3 white dots. Localities: arctic North America and Siberia. Of. vol. 1. p. 109. 



maiirimis. E. disa Thnh. maticinus Dbl. (51 e). Above brown. Forewing with a red-brown band before the 



distal margin, composed of 4 spots placed close together. Each spot contains a black dot, mostly with white 

 centre. Fringes chequered with brown and white. Hindwing unicolorous brown. Beneath somewhat lighter, 

 the apex of the forewing and the distal margin of the hindwing dusted with grey. The band of the forewing 

 is broken up into 4 separate red-yellow spots, only the first 2 still connected, the black clots in them larger 

 than above. This butterfly is found in the mountains of Alaska and British Columbia. On the type-form disa 

 cf. vol. I, p. 109, pi. 37 h. 



viiUcri. E. vidleri Edtv. Tliis species is near the Siberian sedakovii Ev. (cf. vol. I, p. 105, pi. 37 e), resembling 



it in size, colour and markings; but according to Elwes the difference in the genitalia is so great that the two 

 species cannot be regarded as identical. The band on the upperside of the forewing is yellowish brown and 

 runs straight across the wing, enclosing three small dark brown eye-spots, of which the first 2 have white 

 pupils. The band of the hindwing is shorter than in sedakovii, onlj' reaching the middle of the wing and contain- 

 ing only 2 brown spots, the upper very small. On the under surface the band of the forewing does not reach 

 the costal and the one on the hindwing is very similar to that oi nelhiops (vn\. J, p]. ^7 e) or sedaL-ovii. Found 

 by C'apt. VmLER in the mountains beyond Ijake Seton at Lilloet on the Eraser River, British Columbia. Also 

 occurs in Washington (according to Dyar). 



callkis. E. callias Edw. (51 f). Above brown, before the apex of the forewing with a red-brown spot, in which 



ai'e placed 2 .small, white-pupilled ocelli. Beneath the forewing is red-brown with the costal and distal margins 

 gi'cy and with the eye-spots as above. Hindwing grey, finely striated with brown, with several dark transverse 

 stripes, (lommon on high mountains in Colorado and New Mexico. It is the American form of the Palearctic 

 tyndarns Esp. (cf. vol. I. j). 113, pi. 37 i). 



eplpsodra. E. epipsodea Bllr. (= rhodia Edw.) (51 e). Above brown with 4 or 5 black, white-pupilled eye-spots 



on the forewing and 3 or 4 on the hindwing, all broadly surrounded with red-brown. Beneath the eye-spots 

 are exactly as above and the hindwing has a broad, curved blackish median band. — The egg is suboval, 

 chalk- white. Tiie larva stout, cylindrical, with romided head, and of a dull yellow-green coloiu'; the pupa 

 is brownish white, spotted with brown. The butterfly appears in 10 days. It is common in the mountains of 

 British Columbia and its range extends from New Mexico in the south, where it flies in high-lying districts, 

 hnicei. to Alaska in the north. — brucei EJir. (= sincocellata SHnn.) is a smaller form of epipsodea, with the eye- 

 spots absent and the red-brown macular band almost obsolete. It occurs on high mountain peaks in Colorado 

 at altitudes of 12000 ft. 



.fofia. E. Sofia Streck. ($ = ethela Edw.) (51 e). Above dark brown. forcAving with a smooth-edged submargi- 



nal band of 6 red-brown spots, hindwing with 5 similar spots, of which the last 2 are more isolated. On the 

 under surface the forewing is red-brown in the middle, the band is as above, but the first 3 spots are light yellow, 

 the last 3 red-yellow. The hindwing has a white spot in the cell and 3 whitish spots at the apex, below 

 them 2 white dots. The butterfly is still rare in collections and has been found at Fort Churchill in British 

 ulaskcnsU. North America, in the Yellow-stone National Park and some other localities in Colorado. — alaskensis HoU. 

 is a form of sofia with fewer spots on the wings. The forewing shows only 3 on each siu'face, the hind- 

 wing only 2 on the underside. In Eagle (!ity and at American Creek in Alaska, taken in July. 



yini)i</i. E. youngi HoU. Above velvety dark brown, forewing with a short submarginal band composed 



of red-brown spots. Each spot contains a black dot. The hindwing has a .similar row of spots, but more isolated. 

 The under surface is paler. On the forewing the band is somewhat more continuous even than above. Across
