longest of a series of submarginal longitudinal black streaks. Of these 

 there are two in the extra-discal interspace, and two other one-third as 

 long near the apex. Beyond is a submarginal clear olive gray space, 

 bounded without by a very distinct black marginal line. Beyond is a 

 similar narrow clear space next the gray fringe, which is brown at the 

 ends of the nervules. In the apex of the wing is a single linear dot. 

 Secondaries smoky gray, darker without, with a very slight diffuse 

 middle line. 



Beneath uniform cinereous, while the middle of the primaries is 

 smoky gray, the costa and outer edge gray. The submarginal longi- 

 tudinal lines reappear below, as does the marginal, while the fringe is 

 dark cinereous, paler at the base. On the paler secondaries the mesial 

 dark line is more distinct than above. 



This species in its style of markings is near H obli^ua^ but much 

 larger, olive gray instead of brownish gray; hence the markings are 

 more distinct. The secondaries are smoky gray, while in //. ohliqua 

 they are white. 



Length of body, .95; exp. wings, 2.12 inches.

Whitish ashen gray; head, prothorax and patagia being thus colored, 

 while the rest of the thorax is darker cinereous, the abdomen being a lit- 

 tle paler. The larger part of the fore wings is of a pale whitish ashen, 

 concolorous with the head and prothorax. Nearly the basal third is of 

 a darker cinereous than the hind part of the thorax, and this portion 

 embraces three unequal black linear streaks : one extending along the
