" Male. — Kx)>aiHls 1.4 incli. Upper side pruinose blue with a nutallic lustre, somewhat ohecured by fuscous on Becondaries ; hind 

 margin of primaries largely bordered by fuseous, of secondaries narrowly ; fringes of primaries white, black at end of nervules, of sec- 

 ondaries white. Lnder side grey brown mottled with calcareous white; primaries have a sul>-marginal .series of brown lunulcs, not dis- 

 tinct api<ally ; a median row of large round black spot.s, the first four from costa forming an arch, the fifth nmch anterior to fourth and 

 widely separated from it< the sixth duplex ; all edged with white ; on the arc a sub-reniform black spot and one nearly similar in cell. 

 Secondaries have a sub-marginal series of brown lunulcs ; a median sinuous row of round black spot.s, less conspicuous than tho.se of pri- 

 maries, except the first, fourth and last ; the second, filth, sixth and seventh half the size of the first ; on arc an indistinct bent streak ; a 

 small black spot in cell, a iargi' one on costa and a third below cell ; fringes beneath in both wings cut by brown. Body above blue, 

 beneath thorax blue grev ; legs black and white ; palpi white, black at tip and on upper side ; aniennsp annulated black and white ; club 

 bl.ick, tip fulvou.s. Kroin collection H. Edwards. Taken in the Sierra Nevada, Cal.''

 E.xpands IJ inch. Malt', abo%'e, greenish blue not very hi.strou.s ; a discal mark on primaries; blackish 

 borders at exterior margins, broadest on primaries; fringe white. Female dark brown, lender surface in 

 both sexes grey with discal, mesial and sub-marginal spots as in allied species. California, not scarce.

 " California.'" I do not know this species ; the name, at any rate, must give way, as Dr. Herrich-Sehaefter 

 has already employed it in 1850 for a Mediterranean species.*)

 One of the largest N. American species ; I have not yet seen the female, but Boisduval says: " Upper 

 side of female dull brown, spotted with fulvous, as in the allied species but of a paler tint." California, rare.

 Chrysophanus Dorcas, Edwards, Syn. N. Am. Butt., p. 32, (1872). 

 Size of Phlaeas. Male, upper surface primaries dark brown, glossed with purple on discs, edge of costa 

 orange; a black discal spot, another within the cell, and sometimes a third one between this latter and the in- 

 terior margin. Secondaries, a black di.scal mark, midway between this and the exterior margin are two small 

 spots; a small orange spot at anal angle continued in one or two more or less dimly defined lunules; fringe 

 smoky. Female more of a reddish cast on the di-scs, no purple reflections ; in addition to the spots of the male 

 there is on the primaries an irregular mesial row of nearly confluent black spots ; secondaries also with mesial 

 row of like spots; fringes white. Ll^nder surface both sexes yellowish, spots on primaries arranged as above 

 with the addition of a row of sub-marginal spots, the three nearest inner angle distinct, the others .scarcely dis- 

 cernable. Secondaries have the spots of upper surface represented by mere black points or dots, a connected 

 row of orange sub marginal lunules, the four nearest the anal angle brightest. Labrador, Canada, New Eng- 

 land States and New York. Kirby's figure of Dorcas agrees exactly with Epixanthe ?, and the wonder is 

 that their identity was not long ago discovered. I give below the short description of Dorcas that commences 

 Kirby's article ; this is followed in the Fauna Am. Bor. by another, much longer, but in part more obscure 

 diagnosis, which want of space will not allow of in.sertion here: 



" Dorca.s Lycocna, wings above brown-ferruginous dotted and spotted with black ; beneath tawney ; primaries with black spots and 

 crescents ; secondaries obsoletely dotted with black ; marked at apex- with obsolete orange crescents. Expansion of wings 1 inch. Taken 

 in Lat. 54°."
