Triphysa. 42 



with a pale line within the eyes ; hind-wings brown, tinged with green at the base, with an inter- 

 rupted white band, broken into spots, within the eyes. Expands from i| to li inches. Common, 

 though somewhat local, on moors and mosses in Northern and Central Europe, including Ireland, 

 Scotland, and the north of England. It has also been met with in North Wales, Lincolnshire, 

 Norfolk, and it is said in Ashdown Forest, in Sussex. It is found in July ; and the larva, 

 which feeds on cotton grass near the roots in May, is green, with white longitudinal lines ; and 

 the pupa, which is suspended by the tail, is also green. 



GENUS VIII. — TRIPHYSA (ZELI.). 



Wings entire ; the three principal nervures of the fore-wings much dilated at the base in the 

 male, but only the two first in the female. Club of the antennse round and flat. The only 

 European species, T. Phtytie (Pall.), is found in South Russia and Siberia, and there are one or 

 two other species in Northern Asia, among which is T. Sitnbccca (Eversm.). T. P/iryne expands 

 from I to 1 1 inches ; the male is brown, with whitish hind margins, and the female is dirty white. 

 The under side of all the wings is brown, with the nervures and a marginal line on all the wings 

 white, and a marginal row of black eyes with white pupils. It is found in meadows in May 

 and June. 



FAMILY VI.— LIBYTHEID^. 



Fore-wings broadly truncated at the tip, with a prominent angle below it; hind-wings strongly 

 dentated ; the discoidal cell open. The antennae are moderately long, and gradually thickened to 

 the extremity; the palpi are very long, and contiguous throughout their whole length, forming a 

 kind of beak, nearly as in the Crauihida;. The front legs are rudimentary in the male, and perfect 

 in the female. The larva: are cylindrical, with a few fine hairs and a smooth rounded head. The 

 pupa is suspended by the tail. This family is now generally treated as a section of either the 

 NyiiiphalidcB ox \.\\t. Eryciiiida;. It contains but one genus, Z?7yV//crt' (Fabr.), which is represented 

 in most parts of the world by a very few species, closely resembling the European L. Ccltis (Esp.), 

 which is brown, with a fulvous basal streak on the fore-wings, beyond which, and on the hind- 

 wings, are several large fulvous blotches. Near the tip are one or two white spots. Expands 

 about if inches. It is found in Europe, south of the Alps, and in Western Asia, in March, June, 

 and July, wherever its food-plant, Celtis Austraiis, grows wild. The larva is green, with black 

 dots, and with whitish stripes on the back and sides. It is found in April, May, and July. The 

 butterfly is figured at PI. 13, Fig. 9. 



FAMILY VII.— ERYCINID.E. 



The palpi generally very small, the antennae long, and the hind-wings slightly grooved. The 

 front legs are rudimentary in the male, and perfect in the female. The pupa is suspended by 

 the tail and a girth round the body. The larva; resemble those of the Lycanidce, of which some 

 entomologists regard the Erycinidce as a section. There must now be nearly a thousand species 

 of Erycinidce described, but, except a few found in the East Indies and North America, the}- 

 are exclusively confined to tropical America. The single European species is likewise the only 

 species of its genus, and has much resemblance to a small Meliicpa.
