terior wings, irrorate with cinereous scales ; no median darker shade 

 lines as in A. oenotrus ; subterminal darker shade dentate, subobsolete. 



Head, and thoracic region above, very deep brownish-black ; on the 

 sides, anteriorly, a few cinereous scales, which extend laterally on pro- 

 thoracic reuiou. Metathorax, clothed with ferrusinous-cinereous scales, 

 which extend centrally on the disc ; thorax, bi-crested. 



Abdomen, above, black, banded with whitish hairs which margin the 

 segments posteriorly; dorsally, the scales are paler than laterally, form- 

 ing a longitudinal shade stripe. Legs, cinereous ; tibiae, darker.

Nearly allied to Erinnyu a;notrus. Cram. sp. The anterior wings are 

 especially very similar. The pale costo-apical shade is longer, better 

 defined and paler; the one on internal margin is also more determinate 

 as to shape. The posterior wings are darker ferruginous than in E. 

 oenotrus^ and the external margin is not so deeply excavate before anal 

 angle. The tegula; in the latter species are largely brownish, and the 

 abdomen is the same shade, not black and not banded. The internal 

 margin of the anterior wings in E. Mfi-ianse, is much more undulate, and 

 the whole insect much more robust. I do not know, from the short 

 notice, what species is intended by Dr. Herrich-Schaeffer under the 

 name " ue^iottus," and to which a second species is said to be allied. 

 An inspection of Cramer's figure will show that my determination of E. 

 cenotfus, as a species with unbanded abdomen, is correct. Fig. (jr. PI 

 3i)l, Cramer, I refer, following Mr. Walker, to E. Alope.

Smaller than E. Met-ianse, more brownish, the transverse lines plainer, 

 costal paler markings, more distinct. Abdomen, entirely brownish, 

 slightly margined with brighter scales on the segments. Prothoras, 

 and head above, blackish, but the thoracic region above is mostly co- 

 vered with brownish hairs, concolorous with abdomen. Underneath, 

 the wings are crossed, medially and subtcrminally, with dark shade lines;
