416 ARGYNNIS. By Dr. Th. Lehivunn. 



cera a,s nevadensis, is really a form of coronis with very pale under surface, taken by him at Virginia City in Ne- 

 vada. Later, in 1878, after Mead and Morrison had brought from Nevada a goodly number both of coronis 

 and of the true nevadensis, the error was cleared up. nevadensis $ is aiways easy to recognize by the green 

 colouring of the under surface. Expanse: ^ 2,1 — ^2,5", 9 2,5 — 3". The range of coronis extends from 

 southern California through Oregon and Washington to southern British Colombia, in the East to Utah, Nevada, 

 Montana and Alberta (Crows Nest, Geddes); but in Colorado is has not been found so far. 



snyderi. A. snyderi Skinner (86 b) is rather larger than the preceding. ^J above pale ta\\^^J^ the basal area 



slightly obscured by fuscous, the black markings moderately heavy, at the termen indeed very fine, but 

 sharply defined against the light ground-colour. Under surface of forewings with 2 subapical and 5 sub- 

 marginal spots, all distinctly silvered. On the under surface of the hindwings the greyish-green ground-colour 

 is interrupted by a narrow submarginal band of pale buff; all the spots large and well silvered. $ very 

 much like (^, but on the underside the hindwing has the ground-colour from base to outer third brownish 

 instead of grey-green. Expanse: (^ 3,0", $ 3,30". Early stages, like those of the preceding, unknown. Its 

 home is Utah, where it occurs together with coronis. 



liliana.. A. liliana H. Edw. (86 c) stands about midway between A. coronis and callippe. ^ above fulvous, va- 



rying from pale to dark, the black markings rather slight. On the hindwings the median spots united into a 

 fine, continuous band; the light submarginal and discal spots generally paler than the ground-colour. 

 Under surface of forewings pale buff, the basal area and inner margin to below the cell light brown, some- 

 times redbrown, the median interspaces and the end of the cell yellowdsh; some specimens have also the 

 veins in the discal area dusted with reddish; before the apex a brown patch with 2 — ^3 silvery spots; also 

 the upper 5 submarginal spots heavily silvered. Hindwings brown, but little mottled with buff; submarginal 

 band narrow, brown-ochreous ; the spots large and well silvered. $ much paler than (^, with the marginal spots 

 on both wings very pale. Under surface very much like that of c?- the basal area and the nervules of the 

 forewang more red. Expanse: 2,2", $ 2,4". Egg yellow; conoidal, at top truncated and somewhat depressed, 

 the height not exceeding the diameter of the base; with 22 — 23 vertical ribs which are as in other spe- 

 cies of the genus. From eggs that were laid in the first half of July, the larvae emerged in 13 days, going 



baroni. at once into lethargy (Edwards); but nothing is known of their further development. — ab. barotli Edw. 

 refers to an aberrative form deviating from typical sjDecimens in the abnormally heavy black markings. The 

 two marginal lines on the upper surface of both wings very heavy; the submarginal lunules united into a 

 broad continuous band. Also the round postdiscal spots are united to a band reaching from Costa to upper 

 median nervule, with 2 black spots below it in the median interspaces. On the under surface the sub- 

 marginal silver spots on the forewing are united into a solid bar, the corresponding lunules on the hindwings 

 being changed in like manner. The 3 anterior costal spots of the second row confluesce into a single large 

 spot, liliana is found in northern California (T3rpe from Napa Co.). Specimens from near Los Angelos (Godman 

 and H. J. Elwes) greatly resemble callippe with which the species generally is found. 



laura. A. laura Edw. (87 b). (^ above deep reddish fulvous, with both «angs slightly obscured at the base and 



with heavy black marldngs; the broad marginal lines enclose a few small spots of the ground-colour. The 

 discal spots on the hindwings are lighter in colour than the ground. On the under surface the forewings 

 are reddish-orange, the apex and inner margin buff; the apical and anterior mai-ginal spots mostly well sil- 

 vered. 9 much paler than (^, otherwise very similar. Expanse: ^: 2,2", $ 2,4". laura replaces A. coronis 

 in Nevada; being possibly only a form of that variable species. Outside of Nevada it is found also in northern 

 California, Oregon and Washington. 



macaria. A. macaria Edu\ (88 a) is closely related to both coronis and laura, being even of smaller size than the 



latter. (J above brighter fulvous than coronis, the black markings very light. The median spots, especially 

 on the hindwings, dissolved into single short thin striae, the discal spots quite insignificant. Both terminal 

 lines exceedingly fine; but the base of both wings heavily obscured with fuscous. Forewings above orange- 

 red, the apex yellowish-buff; the upper submarginal spots slightly silvered. The hindwings have the distal 

 area yellowish, the discal and basal areas mottled with bro^vii, the submarginal band clear buff. All the 

 spots large and heavily silvered. $ paler than ^. On the hindwings the median spots corresponding to the 

 second silvery row underneath much paler than the ground. The black markings even lighter than in o- Ex- 

 jDanse: ^ 2,0", $ 2,2". The life history is not known. A rare species, confined to California and Nevada. 



caUipe. A. callippe B.sd. (85 e). Forewings produced, narrow, moderately arched. ,^ above dull fulvous, with the ba- 



sal area broadly obscured, both wings at the inner angle , and almost - jj of the hindwings dusted with blackish ; all the 

 nervules broadly edged with black ; terminal border black, submarginal lunules heavy, connected with one another
