Mamestra provisionally," and again, " we think that it will probably 

 become the type of a new genus" (Ann. N. Y. Lye. 97). 



To conclude,' the genera as arranged in my " New Check List," must 

 be modified so far as the Heliothince. are concerned, from Mr. Smith's 

 observations, but I would refer the student to my paper in Am. Ent. Soc. 

 for what seems to me the most natural arrangement of the genera. The 

 genera of the Stirii/ice, here fully discussed, may be placed between the 

 Calpiiice and Plusiince, but their arrangement is somewhat optional so far 

 as our present knowledge extends. They have the body shortly scaled, 

 the thorax short, collar and tegulae deflected or not closely applied, the 

 abdomen weak, untufted, the shape clumsy. The object of the present 

 paper is attained in showing that the Stiriince have certain structural 

 features taken from the already indicated sub-family groups with which 

 they have hitherto been associated, but united in a different way, and are 

 thus equally entitled to recognition as a sub-family of Noctuidse.
