A well-marked carina runs backwanl close to the inner margin of tlu; upper wing, Ijccomiiig obscure the nioment it passes its limits and beyond that becoming a small, scarcely perceptiide, stigmat^il ridge to the lower lateral angle of the cremaster, just befiu'c reaching which it again liecomes distinct: so. in front of the basal wing tuber- cle, there is a slight indicaticm of its presence in a low, broad, scarcely perceplilj'o ridge, running to the iiase of the frontal projecticni. The thoracic dorsal elevation is also slightly compressed and follows as a blunt, low ridge to the (â¢remaster, forining along tlie cnist a tine modiodorsal sulcation on the tnoi-ax. Snrfac? oliscureiy vermicu- late. Cremaster tetra(|uetral, broader below than above, all the sides broadly snlcate, but especially beneath, where it is also jn'ovideil apicaily with a deep inedioventral sulcation, of which there are faint indications also upon tlie seginents in advance of it and especially iip(m the eiglith. The truncate extremity of the cremaster is strongly Ilooklets not very large, with a slender stalk which tapers from apex to base, and is cri-tvned witli a very large, almost lieniispherical. reversed cup. tliree or four times as liroad as the base of the stalk. This American gemis is {'oniposed of a single speoies, whicli extends of tlie Rocky Mountains from tiie middle of the Alleglianiaii fauna to Guate
