This species has the veuatioii (uo subcostal cell) of Lophodoiita, and also agrees in the 

 anteuure aud shape of both pairs of wiugs. Dr. Dyar having called my attention to the absence 

 of a cell, I have reviewed the generic characters. 



In its color and markings it is more like N. sfniejuhi than a Lophodonta, and it is this 

 superficial resemblance to Notodonta which doubtless has led to its reference to that genus. This 

 species in general appearance, color, aud markings is allied to and represents in our fauna the 

 European L. trepidn(trcmnla). Thus the genus Lophodonta is represented in the European fauna. 

 Its larva, jiidging by Buckler's flgure, is like our L. aiu/ulosa in shape, but marked with obliipie 

 yellow and red bars. It is to be seen whether the European genus Peridea, to which trvphla is 

 referred, is synonymous with the American Lophodonta.

Moth. — $ and 9 . Antenna? heavily pectinated to tip, more so than in Lophodonta, LophopteryXy 

 or Xotodonta, and only less so than in Dasi/lophia (simple in 2 frhnaciila). 



Palpi stout, slightly longer than in Lophodonta, and extending a little farther beyond the 

 front. Eyes naked (both in the European trimacula and in geoi-f/ica), as they are in Lophodonta. 



Fore wings rather shorter and broader than in Lophodonta, less produced at the squarish 

 apex; outer edge less oblique; a large broad tuft on the inner edge. A subcostal cell present in 

 i). (jeorgica (but absent in the European trimacula). 



Hind wings a little shorter and rounder at the apex than in Notodonta or Lophopteryx. 



Larra. — That of the European species noctuiform, with no tubercles, and much as in that of 

 Lophodonta. 



Our I>. georgica is very nearly allied to the European D. trimacula in structure and in 

 markings, only differing in a remarkable and unexpected way, considering the close similarity in 

 other respects in the two species, there being in the latter no subcostal cell, the venation being- 

 much as in Lophodonta. 



Hiibner founded his genus on D. crenosa, chaonia, querna, and dodonam, not mentioning 

 trimacula (dodoiiwa being a synonym of it),. which is closely allied with our species. Whether all 

 these species are truly congeneric I can not state, since I have only trimacula to refer to, and since 

 European authors do not seem to have critically examined the structural features of these species.
