full and rounded than the males. The wings are thickly dusted with white 

 scales, bordering the dark bands and checkering the fringe with white, with 

 distinct but diffuse discal dots on both wings. Beneath, much white is 

 mixed with the ochreous tint, and the three bands are very distinct.

Brunswick, Me., frequently taken late in dune and early in July in open 

 pine-woods, flying in company with Eujidonia notataria (Packard, Mus. Peab. 

 Acad. 8c.) ; Portland, Me. (Morse, Mus. Peab. Acad. Sc.) ; Boston^ Mass. 

 (Minot) ; Salem, Mass. (Pickering, Harris Coll. Mus. Bost, Soc. Nat. Hist.) ; 

 Albany, N. Y., May 21 to June 7 (Lintner) ; Missouri (Riley). 



This moth may be known by the dark ochreous-brown fore wings, the 

 ochreous hind wings, with the three darker bands, as well as by the bushy 

 plumose antenna?. It differs from the European Ematurga atomaria in the. 

 wings being less mottled with white or ochreous; the females of the two 

 species are much alike, but ours differs in the heavier outer band and lighter 

 inner band on the hind wings, the outer submarginal band wanting beneath 

 in E. atomaria. The sexes differ in this genus much more than in Fidonia. 

 The females are much lighter, with white speckles and distincter bands than 

 the males, and with quite differently-shaped hind wings. The specimen from 

 Missouri is much whiter than usual in the spaces between the brown lines, 

 both above and beneath. The larva of the European E. atomaria feeds on 

 the Lotus and Centaurea,

Body unusually short and thick; abdomen short, not extending to the inner " 

 angle of the hind wings. Head rather full and convex in front. Palpi long, 

 extending about one-third their length beyond the front, with very long 

 dependent hairs; third joint rather long, obtuse at tip. Antennae in male 

 with broad pectinations, not plumose, the branches not spreading as in 

 Ematurga; in female simple. Fore wings much as in Ematurga, but the 

 costa is more sinuous; outer edge slightly bent, much as in Ematurga. 

 Hind wings much as in Ematurga. 'out the apex is inclined to be a little 

 more rounded, and the outer edge more bent and more deeply scalloped. 

 The venation differs from that of Ematurga in there being six instead of five
