2 9. — The li'uiales are light stone-gray, with an indistinct double row oi 

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

 terior edije of the second abdominal segment ; tiiey are pale ash, and each one 

 is crossed by a fine black line. 



Length, 0.50 inch. 



Cambridge, Mass., April 25 (Morrison), lalieled '^olivacearia, type". 



The artist has not drawn the lemale well, the posterior half of the body 

 behind the wings being too full — too nuich like Aiiisopfenjx. 



I am inclined, after an examination of a lype-specimen, to refer Mr. 

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

I\[al('. — Anlemne sub|»ectinated, each pectination lieing tubercilliforni, 

 and ending in a p<nicil of long hairs. Palpi very shod, not reaching as far as 

 the front. The head in front is smaller, 1>ut the scales project more than in 

 A/iisopfen/.r and Phigdlia. Fore wings much rounded toward tiie apex, the 

 Older edge very ol)rHiue, neariy as hmg as the inner edge. The hind wings 

 longer tlian in Anisopteri/.v and Pliigulia, the outer edge shorter and less full 

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

 from Ihi' sul)costal ; there are six subcostal vt'imh^s, and their disposition is 

 much as in Aniso]>l('nj.r.\m\ less curved up toward thecosta; the second sub- 

 costal vcnide is twice ;is long as in Anisoplcru.r. Jli/ber/iia dilfers from both 

 the two irenera, mentioned in the (irst median venule co-originating with the 

 second. Our single American species is ochreons in color.
