Body moderately stout, sometimes very thick and hairy ; the head, 

 however, is smaller than usual in proportion to the body, while the male 

 abdomen is rather long and slender, though occasionally stout. Head broad 

 in front, the clypeal region being rather short. The palpi are usually stout 

 and large, exceeding the front, with the first and second joints subequal in 

 length; the third joint small, not distinct from the second. Male antenna 1 

 cither simple and ciliated or slightly pectinated or plumose. Wings 

 moderately large or quite large. Fore wings triangular, with the costa 

 usually straight, the apex more or less rounded, the outer edge sometimes 

 serrate. Hind wings full and rounded, sometimes scalloped or serrate. 

 Venation : the costal vein is usually free from the subcostal vein, sometimes 

 (as in certain Ctjmatophonv, C/eora, and Gnophos) anastomosing with the 

 subcostal; the number of branches of the subcostal vein varies from five to 

 six; when the subcostal cell is present, it is long, linear, irregular; only in 

 Chora is it rhomboidal as in the Ennomince. Hind legs sometimes with the 

 tibiae much swollen, .and the tarsi short in proportion. In style of coloration, 

 the species are usually ash-gray, like the bark of the trees to which they 

 cling; this granite-gray color is very persistent, the species of Paraphia 

 forming an exception. When rubbed, the individuals of many of the species 

 tu i-n whitish. 



The females of a few of the lower North American genera (Anisopteryx 

 and Ilybernht) are wingless. 



Larva and pupa. — The caterpillars arc either slender, with sometimes 

 (Anisopteryx aatumnatd) a third pair of abdominal legs, and the head round, 

 or, in the larger species (Pltigalia and Eubi/ja), the head is square in front, 

 each side ending in a tubercle ; sometimes tuberculated on one or more rings 

 of the body. Pupa brown, acutely conical, situated in leaves, or subter- 

 ranean. 



The venation of Anisopteryx and ILbcntia is so much like that of 

 Eubyja and Biston that I have removed them fiom the place usually
