liowevcr. is siiiallcr lliaii usual in propoitioii to the Ixidv, while (lie male 



aiiddiiifij is rather loii^f and slender, thmiiih (iccasionallv stout. Head In-oad 



in front, llie clypeal rei^ion hein;,' ral her short. 'I'lu^ |ial|ii are nsnallv stout, 



and larijp, cxceedinic the f'rout, with the first and second joints sulje(|ual in 



Icnglli; the third joint small, not distinct t'ron) the second. Male antenna; 



either simple and ciliated or sli^ditly Jjcctinalcd oi- plumose. V/inirs 



moderately large or (piitc large. Fore wings triangular, with the costa 



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



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



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



(as in certain C^/iixitopliorcr, Clcora, and (_1 iiophus) anastomosiuii- with the 



subcostal; the number of brandies of the subcostal vein varies from live to 



s!.\: when the subcostal cell is present, it is long, linear, irreirular: onlv in 



Clcora is it rhoml)()idal as in the EniKunhid'. Hind legs sometimes with the 



tii>i;e much swollen, and the tarsi short in ];roportion. ]n style ol" coloration, 



the species are usually ash-gray, like the bark (»f the trees to which they 



(ling; this granite-gray color is veiy persistent, the s|)ecies of l^anqiliia 



forming an exception. AVheii ndibed, the individuals of many of the species 



turn whitish. 



'\ he females of a few of the lower North American genera {Aiiisoptciifx 

 and Hijherniii) are wingless. 



Larva and pupn. — The caterpillars are either slender, with sometimes 

 (Anhoptcryx niilHuniala) a lhii-d pair of abdominal legs, and the head round, 

 or, in the larger species {I'lt'ignlia and Euhi/Ja), the head is sfpiare in front, 

 each side endinir in a tubercle ; sometimes ttd)erculated on one or more rings 

 of th" body. Pupa brown, acutely conical, situated in leaves, or stditer- 

 iane;in. 



The venation of Aiiiso-jfrri/x and Jlihcniia is so much like that of
