side of tlie second joint. Fore wings witli l)laclc scales at tlie base and extending- along- the inter- 

 nal edge of tlie wing; a black basal line interrupted by the cubital \ein: a double black line on 

 the basal third of the -n-ing composed of a large scallop in the discal and a larger one in the 

 subniedian space. Sliddle of the wing entirely clear ocherous. Along, niucli-curxed linear discal 

 black mark, from the inside of which a long, broad, smoky, blackish shade curves around, interrui)t- 

 ing the extradiscal line and ending near the internal angle, behind the inner end of the whitish 

 snbapical patch; in its hinder end near the internal angle are three black slashes situated in the 

 interspaces, and from it a short narrow l)la(k line crosses the second cubital venule, and which is 

 bordered by a narrow white line. FLxtradiscal line double, a deep long scallop parallel to the discal 

 mark, and two short scallops in the first cubital space. The white snbapical patch is unusually 

 broad, beginning- on the first cubital venule and ending on the apex. A scalloped marginal l)]a(k 

 line. Fringe ocherous, with dusky venular dots. 



Hind wings pale sordid whitish at base, becoming smoky externally, and crossed by a difi'use 

 whitish line which is slightly bent in the middle of the wing. No dusky spot at the internal angle. 

 The abdomen is pale ochei'ous. The imderside of the wings is ocherous. the dark shade of the 

 fore wings aijpearing, though faintly. 



I have not seen the male of this ocherous form, but Harvey describes it as differing from the 

 5 "by the subterminal line being more nndulatory, by the less prominently contrasting brown 

 and whitish shades beyond the cell subterniinally, while the antenn:e are pectinate." 



Expanse of wings, S 33mm., 9 35 mm.; length of body, 9 1(>-17 mm. 



Geographical di.str!hidion. — Apparently mostly contined to the Austroriparian subprovince, 

 but occasionally met with in the Appalachian.

Moth. — One <? and four 9 (in the Edwards Coll). Antenna^, palpi, and vestiture of the head 

 above and in fnmt just as in //. suhrotaia. but tlie pectinations of the antenn;e are a little longer, 

 though the shape of the wings and the markings are ju.st the same. The antenn;T? are white 

 above, with a black dot at base. Front of the head more hairy and with longer hairs than iu 

 H. a^iarte, but the palpi are not so long, though very near in shape, black above and gray beneath. 

 Teguhe edged with black, as iu H. Kitperlxi, and the crest on the mesothorax as in H. unperha and 

 astarte and allied siiecies. Fore wings and body of a pale and whitish gi'ay, tinged with a decided 

 sea or pale olive green. Thorax with two curvilinear black lines, one on each side on the i>ro- 

 thorax, meeting in the middle of the body. Thorax behind with black cross lines, and the tufts 

 and teguhe tipped with black. 



Fore wings short and broad, the apex more rectangular than usual except iu sxiperha ; oliv'e 

 and yellow scales at base of the wing, the irregular patch interrupting the basal black line, which 

 forms a diffuse patch between the origins of the cubital and submediau veins. Just bej^ond is a 

 transverse sinuous dark line, curving suddenly inward on the costa, curving outward on the 

 subcostal and cubital veins, and curving in again in the submediau si)ace, then directed obliquely 

 outward and ending on the inner edge of the wing. From the angle on the subiuedian fold a 

 narrow interru])ted line extends along the internal vein to the black line situated on the inner 

 third of the wing, and which is very sinuous, and ends iu a black patch both on the costal and
