BY J. A. LINTNER, 

 [Read before this Society, Oct. 16, 1874.] 



Calocampa impera, n. sp. 



Palpi brown, fuscous beneath. Collar sinuated, pale ocliraceous, traversed ■ 

 by a whitish line, and separated from the dark brown thorax by a fuscous 

 stripe. Abdomen flattened, pale brown, with a tuft on first segment, of a 

 darker brown than the thorax. Anterior wings whitish on the disc, tinged 

 with brown ; costal margin dark brown ; internal margin and nervular inter- 

 spaces lined with reddish (vandyke) brown, the latter cut by the dentated pale 

 marginal band. Anterior transverse band whitish, obsolete above, but well 

 marked below the median nervure in two acute dentations, the upper one of 

 which bisects a blackish basilar line in cell lb reaching to below the reni- 

 form, and is bordered below by a similar line not extending quite so far out- 

 wardly ; on the internal margin at the base, two short fuscous lines ; a dis- 

 tinct fuscous line running from the reniform to the subterminal, between 

 veins 4 and 5. Posterior transverse band indicated only by a black dot on 

 each vein. Reniform large, oblong, constricted centrally, black bordered, sub- 

 obsolete superiorly, with an inner ring of similar form, broadly bordered 

 before, behind and beneath with brown, resembling that of vetusta. Orbic- 

 ular inconspicuous, pyriform, outlined by a few blackish scales, and includ- 

 ing a central spot of blackish scales. Nervules marked with brown scales. 

 Posterior wings brownish-gray somewhat paler basally, with brown marginal 

 scales between the veins, more prominent towards the apex. Beneath, thorax 

 of a lighter brown than above ; abdomen with blackish hairs ; discal spot of 

 posterior wings large, conspicuous, bisected by the pale, cross-vein, as iu 

 vetusta; the median band more dentate than in vetusta and about equal to 

 exoleta. 



Expanse, 2.50 inches. 2 5 s, 1 ? . Hahitat, Albany and Schoharie, 

 N. Y., April 20th and June 1st. 



This species has, very strangely, been confounded with the ve- 

 tusta of Europe, to which it bears very little resemblance. It 

 differs markedly from tliat species in the presence of its conspicu-
