6 if. — Compared with A. ofisulata Guen., with which this species struc- 

 turally agrees, the wings are much produced, and the primaries still more 

 acute. The front of the head is not colored dillcrcntly from the l)ody, and 

 the palpi are stout, porreet, but not passing beyond the front ; body and 

 wings, including fringe and ])iilpi, ash-gray, paler than in A. ossulutn. Vmv 

 wings crossed by three dark, distinct lines (often obscure) ; they are obrupie, 

 w^avy, but not sinuate, being straight in their oblique course : inner line remote 

 from the base of wing; second line runiiing just beyond the tine dark discal 

 dot, nearly touching it, and much nearer the outer than inner lin(!; outer line 

 straight, parallel with the outer edge; tringe pale gray, speckled finely with 

 dark, dark at base. Hind wrings paler than primaries, discal dot more distinct, 

 with three faint lines beyond the discal dot. Beneath, much as above; more 

 densely dusted than above on both wings; posterior half of primaries, except 

 on outer edge, clear whitish ; discal dots more distinct than above ; the two 

 outer lines on the fore and three outer lines on the hind wings distinct.

 (Boll, Miis. Peab. Acad. Sc). 



This peculiar species has the front not dark as usual. i)nt concolorous 

 with the body; this, with the ])ointed lore wings, with their long, very 

 oblique outer edge, which is much less convex than in A. ossulata, the dark 

 fringe, straight lines, and densely-dusted wings, will separate it from any other 

 species known to me.
