412 ARGYNNIS. By Dr. Th. Lehmann. 



yellowish, the termen brown; a rather narrow, greyish-buff subniarginal band, strongly invaded by rays of 

 the dark ground-colour. The spots of the outer row generally well silvered, those at the base and termen 

 less distinct. The $ has the distal half more or less clouded with yellow above, the black markings very 

 heavy and conspicuous; underneath the spots richly silvered. From A. behrensi, likewise of California, oweni 

 differs in the much heavier black markings of the (J, and in that the under surface of the hindwings in both 

 sexes is mottled with yellow at the base, whereas in behrensi it is uniformly dark brown. Expanse: 2,25 — -2,4". 

 oweni is pretty common on Mount Shasta in California, at elevations of from 7000 — 8300 ft. Nothing is known 

 of the earlier stages. 



corneUa. A. cornelia Edu\ (87 b). cJ. Upper surface of both wings from base to the median row of spots dark brown, 



only the far end of the cell of the forewing and the distal area of both wings reddish-fulvous. The dark 

 markings rather feeble, the terminal lines fine, confluent on the veins. Under surface: Forewings from base 

 to the clear yellow submarginal band almost uniformly reddish-brown, only the discal area faintly laved with 

 yellowish. The silvery spots small, but well silvered. $ above duller red-brcwn, with the dark markings heavier, 

 especially in the discal area. The terminal spots on the forewing pale brownish-yellow, the terminal lines con- 

 fluent towards the apex. Beneath like the ^. but with the basal area darker and the spots more briUantly 

 silvered. Expanse: J" 2,3", 5 2,5". Nothing has been published on the life-history of cornelia. It flies together 

 with A. electa and hesperis in Colorado. The types came from Manitou and Ouray. 



electa. A. electa Ediv. (87 b) is found in the mountains of Colorado, spreading northward to Montana, in 



the South to New Mexico. Mead and others treated it as a variety of A. atlantis, from which it may be di- 

 stinguished, aside from its smaller size, but the relatively broad forewings and much weaker black markings. 

 (^ above dull reddish-fulvous; the markings on the forewing moderately heavy, on the hindwing narrow. On the 

 forewings the marginal lines separate, enclosing a narrow band of pale brown spots. The base of both wings 

 slightly obscured. Under surface: Forewings pale cinnamon-brown, with the apex darker. Hindwing brcadly 

 deep cinnamon-brown, slightly clouded with yellow in the discal area; submarginal band brownish-yellow, 

 frequently invaded proximally by the dark ground-colour. The silvery spots are mostly very well marked 

 and distinct, only occasionally more or less obscured or quite obsolete (transition to hesperis). $ very much 

 like 3*, differing only in the somewhat heavier markings. The early stages are unknown. Mead has observed that 

 freshly captured specimens of electa have a strong odour of musk. Its range comprises the mountains of New 

 Mexico, Colorado and Montana. 



Columbia. A. Columbia H. Edw. (86 b). Closely related to electa, but of much larger size. (J above pale reddish- 



fulvous, the spots of the median band on both wings rather large, but distinctly separated. The parallel margi- 

 nal lines, especially on the forewing, are, in contradistincticn to electa, united into a sohd border, between 

 which and the sagittate marginal spots a series of very pale spots. Under surface of the hindwings light ferru- 

 ginous, slightly mottled with buff on the disk and at the base. The submarginal band narrow, buff, sometimes 

 almost wholly obscured by the darker ground-colour. The spots small, but brightly silvered. $ easily distin- 

 guished from S and froni electa 9 by the much lighter colouring of the upper surface, from the former also by 

 the heavier dark markings. The spots of the median band angled, partly lanceolate, those of the outer, t-erminal 

 row aJmost white. Expanse: 2,25 — 2,5". Originally described from 4 ,^^ from Labache Lake in the Caribou 

 District of northern British Colombia; types in Holland's collection. 



hesperis. A. hesperis Edw. (87 a, b) resembles ^4. atlantis, with the forewings in both sexes elongate, rather 



narrow and moderately arched; the sexes a^jproaching one another in size. (^ above deep fulvous, shaded 

 with fuscous for a short distance from the base. The black spots of the median band heavy, more or less 

 confluent, the nervules being heavily scaled with black. Under surface of the forewings pale ferruginous, 

 the apex buff, like the termen shaded with dark red-brown. Hindwings underneath pretty uniformly deep 

 ferruginous; the submarginal band narrow, mostly clear buff, but sometimes almost lost in the dark ground- 

 colour, as in aphrodite. $ above paler than cj, with the dark markings heavier; the marginal lines confluent 

 towards the apex, and joining the rather heavy sagittate spots of the submarginal row, which are also connected 

 with one another, completely surrounding the often nearly whitish marginal spots. Underneath the $ differs 

 from the (J in the deeper and richer colouring. In neither sex are the light spots silvered, but dull yellowish-white, 

 only occasionally sprinkled with a few scales of silver. Expanse: o? 2,3 — 2,4". Although this species is 

 rather common in the mountains of Colorado, Utah and Montana, nothing is known of its life-history.
