genus ii. — demas (stf.ph.). 



The thorax is short and broad, the abdomen with a rather prominent crest, the palpi 

 with thin hairs, and the last joint short and obtuse. The only species, * D. Coryli (Linn.), 

 has the fore-wings rusty-brown in front and ashy-grey behind, with the round orbicular stigma 

 surrounded with black, and two black transverse lines, the first of which has a strong tooth 

 in the middle, pointing backwards, and the second is nearly straight in the middle of the 

 wing. The subterminal line is whitish, and the hind-wings are brownish-grey. Expands 

 from \\ to \\ inches. It is not uncommon in Northern and Central Europe, and is found 

 sitting on the trunks of trees in May and June. The larva is haiiy, flesh-coloured, with a 

 grey spot behind the head, and a dark stripe on the back ; two black tufts on the 2nd and 

 I2th segments, and short red tufts on the 5th and 6th. It feeds on various trees from July to 

 October. 



GENUS III. — RAPHIA (HUBN.). 



Thorax not crested ; palpi projecting beyond the head, with the last joint small and 

 curved. The antennae are pectinated nearly to the extremity in the male, and have two stiff 

 bristles on each joint in the female. The only species, R. Hybris (Hiibn.), from South France 

 and Spain, has grey fore-wings, more or less varied with brown, with the stigmata and all 

 the transverse lines distinct. The subterminal line is marked with dark lunules between the 

 nervures, and the fringes are intersected with a dark line, and are light at the ends of the 

 nervules. The hind-wings are white, with a dark spot towards the anal angle. It expands 

 about i^ inches. 



GENUS IV. — CLIDIA (BOISD.). 



The thorax slightly crested behind, the palpi slender, hairy, with the last joint short and 

 concealed. 



1. C. GeograpJiica (Fabr.). — Fore-wings varied with white and pale brown, with the fringes 

 spotted with brown and white. There are two white dentated transverse lines bordered with 

 brown behind, the middle of the elbowed line projecting considerably towards the hind margin. 

 The hind-wings are whitish in the male, and grey in the female. Expands about i inch. 

 It inhabits South-Eastern Europe in May and June. The larva is black, with hairy warts, 

 and two white lines on the back. It is w'hite on the sides, spotted with black, and with a 

 yellow lateral line. The incisions are bordered with reddish-yellow. It lives on EupJiorbia in 

 June and August. 



2. C. CIiamiEsyces (Gu^n.). — Fore-wings pale brown, spotted with white on the costa and 

 hind margin, with the two central lines distinct, white, and bordered externally with dark 

 brown The elbowed line is much curved and denticulated, with a very prominent projection. 

 The stigmata are absent, and the fringes are spotted. The hind-wings are uniform dark 

 brown in both sexes. Smaller than GeograpJiica. It is found in South France and Piedmont 

 in May and July, and the larva lives gregariously on different species of Euphorbia. 



GENUS V. — PANTHEA (HUBN.). 



The thorax is densely woolly, but neither thorax nor abdomen is crested. The palpi 

 are very small, with the last joint inconspicuous. The only species, P . Cxuobita (Esp.), has
