bearing long white and yellow hairs, which become black oi 

 grey before the last moult. The head and fore-legs are red, 

 and there are two rows of yellow spots on each side. The 

 cocoon is formed entirely of the hairs of the larva, without a 

 trace of silk. The eggs of the Moth are smooth and green. 



GENUS PHILOROS. 



Ctenucha^ Group 2, Fhihros, Walker, List Lepid. Ins. Brit. 



Mus. ii. p. 283 (1854). 

 Philoros^ Grote, Bulletin Buffalo Soc. i. p. 34 (1873). 



The species of this genus are smaller and slenderer than in 

 typical Ctemccha ; the abdomen is longer, and the wings are 

 generally lined with white, and are narrower than in Ctenucha. 



PHILOROS OPACA. 

 (Plate LXXXII. Fig. i.) 



Clenucha opaca^ Boisduval, Consid. Lepid. Guatemala, p. 84 

 (1870). 



This Moth, which expands about an inch and a half, has 

 brown fore-wings, with the fringes white at the tip. The hind- 

 wings are darker, with the fringes white at the tip and along 

 the upper part of the hind margin. The collar is orange-

 and Central America generally. 



SUB-FAMILY III. PERICOPIN^. 



The PericopincB are another exclusively American Sub-family 

 which contains a considerable number of brightly coloured 

 Moths, measuring two or three inches across the wings, which 

 are very ample, being broad as well as long, and the hind-wings 

 are nearly as long as the fore-wings. The body is compara- 

 tively slender, and only moderately long. The antennae are
