66 COLZAS. By J. Robee. 



marginal . spots , the ? having large yellow submarginal spots. The underside is somewhat deeper yellow 



than in lujale, but otherwise very similar to that of this species. — At Sarepta, and in Armenia and Central 



dirysodona. Asia chrysodona Boisd. (= helichta Led., heckeri Gerh., edusoides Krnlik.) (26b) has been observed; 



presumably a hybrid between erate and edusa. The upperside of this form is orange-yellow in the cfcf, 



pallida, laeing only slightly paler in the ??. — Of erate there occurs also a white $-form, pallida Stgr. — In Central 



liyaleoides. Asia there occurs hyaleoides Gr.-Grsh., a smaller form, with narrower distal marginal band, which bears 



some spots also in the c^ ; it has not yet been ascertained , if this form is an aberration or a seasonal 



diryseis. variety. — chryseis form. nor. (26b), from South Russia, presumably is also a hybrid; the ground-colour 



of the upperside is a beautiful golden yellow, the underside of the forewing being nearly the same; 



however, the apical marking of the forewing above does not agree with that of any species which might 



come into consideration, only the complete, though naiTower, distal marginal band of the hindwing points 



diana. to chri/seis being the product of a cross between erate cf and edusa ?. — We propose the name diana form. hov. 



(26b) for very similarly marked specimens from South Russia which are light yellow; they are presumabl}- 



hybrids between erate and hi/ale. — C. erate is common, but difficult to catch on account of its fast flight. 



ersdwffi. C. crschoffl Alplt. {= aurora Alph.) (26c), from the Tian-shan district, is a pretty yellow species, 



in which also the cf bears a complete row of submarginal spots, the sexes therefore being very similar; 



the hindwing is greenish yellow, with sharply defined yellow submarginal band and a large reddish yellow 



middle spot which has a light centre and is distally produced into a point. — Strongly golden yellow 



tancrei. specimens are named ah. tancrei Aast. — The orange-red ?-form may be named ab. clara nov. — The 



Clara, species flies from the middle of May till July and August, at elevations of 5000 to 7000 feet. 



berylla. C. bcrylla Fawcett (= nina Faweett) (26c), from Tibet, is greenish yellow in the cf, with a 



modei'ately broad, yellow-spotted marginal band, black median spot on the forewing and a yellow one on 

 the hindwing; hindwing darkened. Underside yellowish green, with black middle spot on forewing, a white 

 one on hindwing, a band of yellow submarginal spots on both wings, and black submarginal spots on the 

 posterior portion of the forewing. The ?? vary in ground-colour from lemon-yellow to light orange, the 

 hindwing being strongly darkened; the light submarginal spots rounded or elongate, often reaching to the 

 margin; underside more strongly green, sometimes much darkened. 



romanovi. C. romanovi Gr.-Grsh. (26 c) occurs in Southern Fergana. Its golden red colour renders it one of 



the finest species of the genus. The broad black marginal band of the forewing of the cf is usually without 

 spots, but bears sometimes a row of contiguous ill-defined yellow subapical spots, there being also yellowish 



maculata. submarginal spots on the hindwing; this form is the ab. maculata of dealers (26c). In the ? the ground- 

 colour is paler, the slightly yellow-spotted marginal band being broader and the hindwing darkened, the 

 large orange-red middle spot contrasting sharply. The underside is yellow, the proximal portion of the 

 forewing light orange-red, the submarginal spots of the forewing, which are sometimes absent, are blackish, 

 while those of the hindwing are brownish; the forewing bears a large, pale-centred middle spot and the 

 hindwing a large red-edged double spot of the colour of mother-of-pearl. 



staudingeri. C. Staudingeri Alph. (26 d), from the district of the Tian-shan, is rather variable. The nymotypical 



form from Kuldja is beautifully golden red; the marginal band of the cf is narrow, being obsolete at the 

 apex, while it is broader in the ?, bearing yellow spots in both sexes. The underside of the hindwing is 

 greenish jellow in the cT, reddish yellow in the ?, the forewing being feebly red in the cf, strongly red 

 pamira. in ?, with small dark markings. — pamira Gr.-Grsh. (= pamiri Rilhl), from Southern Fergana, is larger 

 maureri. and has a broader black margin. — maureri Stgr., likewise from South Fergana, is much smaller, the distal 

 margin being spotted with yellow also in the cf , the sulphur-j^ellow submarginal spots being large in the ?. 

 Presumably a distinct species. — C. staudingeri flies from the end of June till Julj' and August at elevations 

 of from 7000 to 12000 feet. 



felderi. C. felderi Gr.-Grsh., from Amdo, is light orange-red, with black margin, which is traversed by the 



yellow veins at the apex of the wing, and with black middle spot; the hindwing has a yellowish band 

 before the black distal margin. The underside, which has nothing distinctive, is without submarginal spots. 



regia. C. regia Gr.-Grsh. (26 d), from Southern Fergana, is magnificently golden red, with a very feeble 



violet sheen in the cf and a stronger gloss in the ?; the black marginal band not very broad, dusted with 

 yellow, the middle spot of the forewing black, that of the hindwing red and inconspicuous. In the 2 the 

 black distal margin is somewhat broader, bearing yellow spots at the apex of the forewing, the hindwing 

 having small red obsolescent spots in the posterior portion of the band. The underside of the cf is beauti- 

 fully greenish j'ellow, with few markings, a black middle spot on the forewing and a brownish-edged one of 

 mother-of-pearl colour on the hindwing; the underside of the hind\ving darker in the ?, the forewing being 

 proximally beautifully golden red. 



eogene. C. eogene Fldr. (26 c), from Kashmir, Ladak, the Pamir and Southern Fergana, is a very variable 



species. The name-typical form has the ground-colour pale golden red, the distal marginal band being 

 rather broad, traversed in the cf by yellow veins only in the apical area of the forewing, and spotted
