hair; palpi pale, antennae pale, tips of joints dark; thorax pale 

 through the middle, dark on sides, pleura pale; abdomen blackish, 

 venter pale; legs pale. Wings longer and more slender than usual; 

 fore wings densely irrorate with dark gray, becoming blackish on the 

 larger spots and on the veins; the larger spots are over the anastomosis, 

 and along the cubital and anal veins. The venation about as in A. 

 grandis, but the cells narrower, and especially the apical cells, the outer 

 margin is thus more oblique. The hind wings brownish, nearly uni- 

 form, but with a few pale spots on outer costal border; venation as 

 in A. grandis, but the pedicel of fork 3 has a spurious vein (really fold) 

 obliquely to the base of fork 2. 



Expanse 38 mm. 



Known at once by elongate, heavily irrorate fore wings; probably 

 referred to by McLachlain, Monog. Revis., p. 379, in a footnote.
