This insect has been placed by Dr. Harris, and others, in the genus 
Procrvs, by Walker m Ctenucha, but the more recent revisors of the 
family, have given it a place m the present genus. The moth is black 
with narrow, ovate wings, expanding a little less than an inch: has a 
saffron collar, and a somewhat two lobed anal tuft. The antenme are

leaf eat their way across the leaf, standing on the uneaten portion. 
At first, they only eat the tissue, leaving even the fine veins, but as

grown, they have not the same gregarious habit, but disperse over 
the vines, or when about to transfer, may forsake them entirelv.

burning the separate leaves that contained them. Besides feedi^o- 0 n 
grape leaves, they also eat the leaves of the Virginia creeper
