LOPHODONTA* nov. gen. 



Head larger thaa in Notodonta, and the pilose front is more prominent 

 than in that genus. Palpi porrect, stout, passing in S a little beyond 

 the front. Pectinations of antenna? much longer than in Notodonta. 

 Prothorax slightly crested. Fore wings more triangular than in the 

 preceding genus; costa straight, apex obtusely pointed. Inner margin 

 nearly straight, tufted prominently at the angle. The discal nervules 

 are placed near the outer third of the wing, so that the 4th and 5th 

 subcostal nervules are much shorter than in the allied genus. Inter- 

 costal area long linear. Secondaries in the %, even with the tip of the 

 abdomen ; costa straight, outer margin much shorter than in Notodonta. 

 Legs like Notodonta. 



Lophodonta ferruginea n. sp. 



Ferruginous or brick red and blackish cinereous. The head and 

 prothorax are ashen black, while the rest of the thorax and fore-wings 

 are ferruginous. Base of the fore-wings ferruginous, interrupted on 

 the costa by two white short lines. Beyond is a dark band, shaded 

 within with ashen, and lined without by four dirty white lunules, which 

 are margined externally with a ferruginous line. Towards the costa 

 beyond this line and within the geminate nearly united dirty white discal 

 dots are some transverse irregular whitish discolorations. The outer 

 third of the wing is darker than the middle, while the nervules 

 are almost black. There is a submarginal waved lunate dirty white 

 line, and while the fringe is dark, opposite the ends of the nervules it 

 is whitish. The tuft on the inner margin is broad and dark. The 

 secondaries are dirty white, with a mesial obscure band, becoming 

 brown towards the costa, which is margined without with whitish. 

 Beyond is a broad dusky band, more distinct upon the costa, margined 

 without with a short white line, becoming more distinct upon the costa, 

 where it is twice waved. Margin black, fringe dusky cinereous and 

 concolorous with the abdomen. 



The body beneath is much lighter, and the wings are still paler, 

 being dirty white and crossed by a common mesial obscure dusky line,
