" lore leys nearly alike ia size in both sexes, scaly. The tibiae armed with numerous short 

 acute spines, set ou 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 angulated near the base. Pseudonychia moderate-sized, 

 strongly bifid, the divisions conical, finely setose. Pulvillus large. 



" Four hind legs rather short. Basal joint of the tarsi long, and often swollen in the males. 

 Ungues and their appendages formed as in the fore legs. 



" Laeva elongate-ovate, swollen, onisciform, generally finely hairy, head small ; feeding upon 

 docks, grasses, and low herbage. Papa short, thick, and entire, with the head-case obtuse."

"Expands 1-G2 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 midwaj- 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 tlie 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 bind 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 Sjiots, are surrounded by light rings." {Lanq, I. c.) 



Var. rutilus, Werneberg. " This is smaller and less brightly coloured than the type, the spots on 

 the underside are much smaller, and the colour 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
