812 C'HRYSOPHANUS. By Dr. M. Pbaudt. 



genius. L. genius Hbn. (145 f, g) is above brown-black, in the disc with a bluish-grey lustre, on the forewing 



between and above the median veins with 2 small hyaline spots of a blue opalescence on being exposed to the 

 light laterally; the hindwing exhibits a large opalescent hyaline spot in the cell, below and behind it 2 very 

 small ones. The under surface is bone-coloured, the hyaline spots are of a more intensely blue lustre than above; 

 the basal areas on both wings and a triangular costal-marginal spot on the forewing are dark brown; the post- 

 discal band with a sharp W at the proximal margin; the anal spots and those on the tails reddish-yellow, pupilled 

 black. Surinam to Brazil. 



niceias. L. nicetus Fldr. (HSg) is more slender, the spots of a dull white, only little transparent, more 



band-like. Beneath dark brown with white transverse lines, the one on the hindwing very broad, similar as 

 in Th. teatae, the orange anal markings very extensive. From Colombia. 



II. Group: Chrysophanini. 



7. Genus: Chrysopliauus Dbl. 



The nearctie flame-coloured lepidoptera do not differ essentially from the palearctic forms: we also 

 find here nearly uniformly large, above golden-red or purple-violet species. The undersides likewise exhibit 

 designs of markings and colourings entirely analogous to the well-known species of the eastern fauna. The 

 biological conditions are also conforming to it, the habits of the larva living on Rumex etc. A characteristic mark 

 for the separation of the group from the Thedini is the 3-branched subcostal, which they share with the 

 Lycaenini. 



Otherwise the venation exhibits few differences; on the forewing the discocellular is almost quite absent. 

 On the hindwing the anal angle is mostly somewhat pointedly protracted, and the hindwing is often extended 

 at the lower median vein into a small short tail. As to the habits compare what has been said in the Palearctic 

 Part Vol. I., p. 281. 



This genus has likewise been divided by Scudder into a number of other genera which, however, are 

 only to be regarded as subdivisions, their names being, therefore, only shortly mentioned. 



I . Subgenus: Tliarsalea Sciidd. 



arota. Ch. arota Bsd. ( l-t-o a). The ^J is above purple with a violet lustre and small diaphanous spots beneath, 



the $ yellow-red, spotted black with darkened basal halves and margins. The underside is light grey, in the 

 $ on the disc of the forewing yellow-reddish; the hindwing exhibits beside the spots a fine black, postdiscal, 

 dentate line, behind it a broad, whitish submarginal band. California. — The larva divergently lives on Ribes. 



virginien- Ch. virgitliensis Ed IV. (145 a) is on an average somewhat larger, above almost the same, beneath darker 



sis. grey, more coarsely spotted, and with distinct Avhite submarginal lunae. California, Nevada and Colorado. 



hcrmcs. Ch. hcrmes Edic. Here also the ,^ is above light red-yellow, at the costal margin and border and at 



the base brown with the same spots as the preceding, the hindwing much darker, with a long pointed tail ; the 

 $ has somewhat more distinct markings. Beneath the ground-colour of the forewings is more tawny, at the 

 border grey, the hindwings also in the basal area grey, similarly spotted as the preceding. Expanse of wings: 

 22 to 27 ram. California, Nevada. 



del Sud. Ch. del Sud Wright (145 b) seems to me to be the best founded upon an aberrative specimen which 



may well be numbered among this subgenus. The animal resembles the $ of arota, but the forewings are without 

 the spots in the distal half of the submedian area, and the apex is broadly darkened. Beneath the hindwings 

 are monotonously yellow, almost without spots. California. 



2.. S u b g e n u s : Gaeides Scudd. 



xanthoides. Ch. xatithoides Bsd. (145 a) is one of the largest species, above likewise purple-brown, in the $ 



more or less light yellow-red, in both sexes with an orange distal margin of the hindwing, in which there are 

 black spots. The under surface is very pale yellowish-grey, distally white, with the usual black spots being 

 white-ringed on the hindwings; those at the border are analwards proximally bordered by orange lunar lines. 

 The species only flies in California. 



dione. Ch. dione Scudd. (145 b) looks very much like thoe (145 c). Above more purely grey-brown with a 



faint violet lustre, the forewing wjth 2 black spots in the cell, the hindwing with an orange marginal band. 

 Also the underside is very similarly coloured and marked, but the spots of the hindwings are differently arranged 

 and the forewings likewise grey. The size is larger than in thoe. Iowa.
