(1) Hypenula cacuminalis Walker. 
Syn. biferalis Walker; opacalis Grote. 
The moth is a native of the southern portions of our territory. 
The figure we give is taken from Walker’s 
type, which is preserved in the British 
Museum. We also give a figure of a 
specimen preserved in the American 
Museum of Natural History, and which 
was determined by Mr. Grote as his 
species, to which he gave the name 
opacalis. The comparison of the two 
figures will serve to illustrate the variability of the species.
