2 9. — The females arc light stone-gray, with an indistinct double row ol 

 dorsal black spots. The wings are quite well developed, reaching to the pos- 

 terior edge of the second abdominal segment ; they are pale ash, and each one 

 is crossed by a tine black line. 



Length, 0.50 inch. 



Cambridge, Mass., April 25 (Morrison), labeled tl olivacearia, type". 



Tlie artist has not drawn the female well, the posterior half of the body 

 behind the wings being too full — too much like Anisopteryx. 



1 am inclined, after an examination of a type-specimen, to refer Mr. 

 Morrison's II. olivacearia to this somewhat variable species.

Male. — Antemuv subpectinated, each pectination being tuberculiforrn, 

 and ending in a pencil of long hairs. Palpi very short, not reaching as tar as 

 the front. The head in front, is smaller, but the scales project more than in 

 Anisopteryx and Phigalia. Fore wings much rounded toward the apex, the 

 outer edge very oblique, nearly as long as the inner edge. The hind wings 

 longer than in Anisopteryx and Phigalia, the outer edge shorter and less full 

 than in the two other genera mentioned. Venation: the costal vein is free 

 from the subcostal; there are six subcostal venules, and t heir disposition is 

 much as in Anisopteryx, but less curved up toward thecosta; the second sub- 

 ial venule is twice as Ion- as in Anisopterxjx. Hybernia differs from both 

 the two genera mentioned in the lirsl median venule co-originating with the 

 second. Our single American species is ochreous in color.
