obsolesceut from the middle of discocellulars ; 6, 7 from upper 

 angle or stalked ; 8 anastomosing with the cell near base only or 

 often anastomosing with the cell to near middle. 



In the genera without an areole its absence appears always to 

 have been caused by reduction from forms which once possessed it.

Eupseudoiyiorplia, Cydosia, Grceperia, Tarachidia and some other 

 genera have the typical trifid neuration of the hind wing of 

 the subfamily Acronyctince, but are by facies and other characters 

 closely allied to the Erastriance, the larvae of such as are known 

 having the anterior prolegs aborted, which is the essential distinction 

 between the two subfamilies. 



Larvce smooth, the warts with single hairs, the anterior or two 

 anterior pairs of prolegs absent, and in method of progression more 

 or less semiloopers.
