CHRYSOPHANUS. By Dr. M. Draudt. 813 



Ch. editha Mead (145 b) is smaller than xanthoides with somewhat less pointed wings, otherwise above edUha. 

 very much alike. The under surface is grey with an ochreous-yellow tint increasing towards the margin; the 

 spots are black only on the forewings, on the hindwings ochreous-grey, finely ringed black. Nevada. 



Ch. gorgon Bsd. (145 b,c). Upper surface lighter purple red with an intense blue-violet lustre, in gorgon. 

 the $ niucli more extensively yellow-red. The under surface is yellow white, between the two submarginal 

 rows of spots there is a complete row of orange lunae on the hindwings. The species is so far known only from 

 California and Nevada. 



3. Subgenus: Chrysophanus Hhn. 



Ch. thoe Bsd. (145 c) has purple-brown forewings with a violet reflection and brown hindwings thoe. 

 with an orange marginal band; the $ entirely resembles our virgaureae. Beneath the forewings are red-yeUow 

 in the disc, grey at the apex, the hindwings blue-grey with a red marginal band with the usual small black 

 spots. Distributed and common in the Atlantic States and Colorado. The larva lives on Rumex. 



4. Subgenus: Epidemia Scudd. 



Ch. mariposa Reak. (= nivalis Bsd.) (145 c). The (J is above purple-brown with a violet reflection, mariposa. 

 the $ extensively yellow-red with the usual small spots. Beneath the forewings are dull yellow-red, the hindwings 

 ashy-grey. This little species is known from California and the Rocky Mountains. 



Ch. zeroe Bsd. (= ianthe Ediv.) (145 d) greatly resembles the preceding, but it is larger, more zeroe. 

 slender, and the wings are more pointed, the cJ exhibits a more distinct red-yellow marginal band on the hindwing, 

 the black spots, particularly in the $, are clearer and more distinct. The under surface is of a duller colouring, 

 the hindwing almost unspotted. California, Colorado. 



Ch. helloides Bsd. (= castro Reak.) (145 d) likewise resembles the two preceding species, it is above helloides. 

 more brightly coloured and more intensely spotted, and in the $ in the basal parts of both wings, particularly 

 of the hindwings, darkened by brown. The under surface is like in mariposa, the hindwings of a more reddish 

 tinge. California, Rocky Mountains. 



Ch. dorcas Ky. (145 d) is smaller than the preceding, the ^ above deeper violettish-purple, the dorcas. 

 $ almost entirely darkened by brown. The under surface is almost monotonously yellow-red-brown. Distributed 

 in Arctic America. — The form: florus Edw., described from the Red Deer River, is larger with a much broader florus. 

 black marginal band almost reaching the discal, zig-zag shaped macular series ; the under surface is more light bro^mi. 



Ch. epixanthe Bsd. (145 e) is the smallest species, above darker, with a faint violet lustre and but epixanthe. 

 few small orange spots, at the anal angle of the hindwing; the $ is above dull grey-brown. Beneath the 

 wings are of a lighter grey, towards the base more blue-grey with the usual spots. From the northern 

 Atlantic States. 



5. Subgenus: Heodes Dalm. 



Ch. hypophlaeas Bsd. (= phlaeas Bsd. <& Lee., americana d'Urb., fasciata Streck., fulliolus Hidst) hypo- 

 (145 c) is the North American representative of our common phlaeas from which it differs above by the more pMaea^. 

 fiery golden red colour, and by the greyer under surface of the hindwings and more prominent black spots. 

 Everywhere common in North America, only in the Gulf States it is absent. The larva lives on Rumex as with us. 



Ch. arethusa Dod. is closely allied to the preceding; forewings in the (J more pointed, the yellow-red arefhusa. 

 colour above more reduced; on the dark brownish hindwings 2 postmedian rows of spots and the black discal 

 spot are more prominent. Beneath the forewings are of a purer yellow, the spots distinctly light-ringed; the 

 grey hindwings exhibit beside the rows of small black dots an orange-red submarginal line. Expanse of wings: 

 (J 30 to 35 mm, 29 to 33 mm. Rocky Mountains (Calgary). 



6. Subgenus: Chalctria Scudd. 



Ch. cupreus Edw. (145 e) is above red-golden with a narrow black niargm, and in the o with spots cupreus. 

 beneath shining through, which in the $ appear also above distinctly black. The under surface is light grey-yellow, 

 in the disc of the forewing red-yellow, of the same colour is a marginal band of the hindwing. California, Oregon. 



Ch. snowi Ediu. (145 e) is somewhat larger, above with somewhat broader black margins and also s)wici. 

 in the ^ with more distinct, small black spots. The hindwings are beneath more dnty grey. Rocky Mountains. 



Ch. rubidus Edw. (145 f) entirely resembles cupreus above, but it is considerably larger, the $ is duller rubidus. 

 and more yellow. The under surface is light grey, almost white, the hindwings almost without any spots, while 

 in the form sirius Edvj. (144 n) they exhibit the usual spots like in the other species. Occurrmg in the Rocky sirius. 

 Mountains and Oregon.
