MR. E. WALKER. ON HETEROCEROUS LEPIDOPTERA 



beyond the hind wings. Legs stout, hirsute ; fore legs densely tufted. 

 Wings broad, not long. Fore wings hardly acute; costa straight 

 except towards the tip, where it is very slightly convex ; exterior 

 border hardly convex, moderately oblique; 1st, 2nd, and 3rd inferior 

 veins approximate at the base. 

 This genus should perhaps be removed from the Notodontidce.
