CHRYSOPHANUS. 307 
" J^ore lerjs nearly alike iu size in both soxcs, scaly. The tibite armed with numerous short 
acute spines, set on irregularly, the tip not produced into a hook. The underside of the 
tarsi also armed with still more numerous spines ; those of the male exarticulate, and 
terminating in an obliquely curved horny point ; those of the joint armed with acute 
ungues, rather dilated and angulatod near the base. Pseudonychia moderate-sized, 
strongly bifid, the divisions conical, finely setose. Pulvillus large. 
" Foui- hind lerjs rather short. Basal joint of the tarsi long, and often swollen in the males. 
Ungues and their appendages formed as in the fore legs. 
" Larva elongate-ovate, swollen, onisciform, generally finely hairy, head small ; feeding upon 
docks, grasses, and low herbage. Pupa short, thick, and entire, with the head-case obtuse.''

"Expands 1"62 to 2 inches. The male is brilliant coppery-red ; all the wings have a narrow 
black hind marginal border. The fore wings have two spots in the discoidal cell, the outer 
one being elongated, and the inner one being merely a black dot ; about midway between the 
outer spot and the hind margin, and parallel to the latter, is an indistinct row of dark spots ; 
the hind wings possess a similar row, and also an elongated discoidal spot. The female is 
larger than the male ; the fore wings have a broader hind marginal band, and parallel to this 
a row of seven large black spots ; there are three spots in the discoidal cell. The hind wings 
are copper, with three rows of black spots, generally clouded over with dusky brown, except 
along the hind margin, which has a broad copper band ; sometimes the hind wings are rather 
broadly veined with copper. The underside is similar in both sexes. The fore wings are 
bright orange-red, with a grey hind marginal border. In the discoidal cell there are three 
black spots, surrounded by grey rings, and parallel to the hind margin is a row of spots 
similar to those just mentioned, and seven in number. The hind wings are pale grey, strongly 
tinged with light blue towards the base, and with a broad and very distinct hind marginal 
orange border enclosing a double row of black spots ; at the base are two black spots, and one 
near the centre of the costa ; there are three spots, two small and round, and one elongated, 
in the discoidal cell, and then one midway between the latter and the inner margin ; beside 
these, there is an irregular row of ten large spots running parallel to the hind margin, and 
these, as well as all the other spots, are surrounded by light rings." {Laiu/, I. c.) 
Var. rutilus, "Werneborg. " This is smaller and less brightly coloured than the type, the spots on 
the underside are much smaller, and the col6ur of the underside is ashy grey, with very little 
tinge of blue. The most distinctive feature, however, is the narrowness of the orange band 
on the underside of the hind wings, near the hind margin. I have examined a great number
