THE CANADIAN ENTOMOLOGIST. 17 



Early in August I took a Papilio asterias % with large blotches of a 

 yellow fungus, as yet unidentified, on the wings. The growth mentioned 

 by Mr. Aaron may be something of this nature. 



DESCRIPTION OF A NEW DREPANODES. 



BY A. R. GROTE, 



Director of the Museum, Buffalo Society Natural Sciences. 



Notwithstanding the variability of D. vat us Grote, of which species 

 D. sesquilinea is stated by Dr. Packard to be the ordinary male form, there 

 can be no doubt that a very interesting species from Maine (Prof. Fer- 

 nald) and Massachusetts (Mr. Roland Thaxter) is distinct from any 

 previously described. In this form the exterior line is without a costal 

 angulation. It may be called 



Drepanodes Fertiatdi, ti. s. 



£ . Larger than the other species, light purplish brown. The two 

 transverse lines composed of broken black lunules shaded with white. A 

 black discal point on primaries. A median diffuse brown shade near the 

 exterior line and continued on hind wings. The exterior line extends 

 straight to costa near apices and is here not angulated ; it is continued on 

 hind wings, but merely as a white sub-lunulated line with black pointlets 

 on the veins. Terminal space on fore wings shaded with brown. Fringes 

 on both wings pale. Edge of secondaries brown. Beneath paler than 

 above, sub-irrorate. A common white exterior lunulated line marked by 

 black pointlets on the veins. Discal dots on both wings. 



Expanse 31 mil. Two specimens examined, not differing in any way. 

 The apices are acute, but not falcate. The costal edge is paler than the 

 rest of the wing. The more brownish color and the peculiarities of the 

 transverse line will at once distinguish this species. I am greatly indebted 

 to Mr. Roland Thaxter for the type taken at Newtonville, Mass., June 

 16th, 1877.
