■side of the second joint. Fore -wings with black scales at tlie base and extending along the inter- 
nal edge of the wing; a black basal line interrupted by the cubital vein; a double black line on 
the basal third of the wing composed of a large scallop in the discal and a larger one in the 
submedian space. Jdiddle of the wing entirely clear oeherous. A long, much-curved linear discal 
black mark, from the inside of which a long, broad, smoky, blackish shade curves around, interrupt- 
ing the extradiscal line and ending near the internal angle, behind the inner end of the whitish 
subapical patch; in its hinder end near the internal angle are three black slashes situated in the 
interspaces, and from it a short narrow black line crosses the second cubital venule, and which is 
bordered by a narrow white line. Extradiscal line double, a deep long scallop parallel to the discal 
mark, and two short scallops in the first cubital space. The white subapical patch is unusually 
broad, beginning on the first cubital venule and ending on the apex, A scalloped marginal black 
line. Fringe oeherous, with dusky venular dots. 
Hind wings pale sordid whitish at base, becoming smoky externally, and crossed by a diffuse 
whitish line which is slightly bent in the middle of the Aving. Xo dusky spot at the internal angle. 
The abdomen is i)ale oeherous. The underside of the Avings is oeherous, the dark shade of the 
fore Avings appearing, though faintly. 
I have not seen the iimie of this oeherous form, but Harvey describes it as differing from the 
9 by the subterminal line being more undulatory, by the less prominently contrasting brown 
and Avhitish shades beyond the cell subterminally, Avhile the anteume are pectinate.’’

MoUl — One 6 and four 9 (in the Edwards Coll ). Anteiinte, palpi, and vestiture of the head 
above and in tront just as in if. suhrotata^ but the pectinations of the anteniue are a little longer, 
though the shaxie of the Aviugs and the markings are just the same. The anteniue are white 
above, Avith a black dot at base. Front of the head more hairy and Avith longer hairs than in 
H. antarte^ but tlie x>Jvlid Jirc not so long, though A^ery near in shaxie, black aboA'e and gray beneath. 
Teguhe edged with black, as in H. superha^ and the crest on the mesothorax as in ff, snperba and 
astarte and allied sxiecies. Fore AAungs and body of a xiale and Avhitish gray, tinged with a decided 
sea or xidle olh^e green. Thorax Avith tAvo curvilinear black lines, one on each side on the x^'o- 
thorax, meeting in the middle of the body. Thorax behind with black cross lines, and the tufts 
and teguhe tipx^^d with black. 
Fore wings short and broad, the apex more rectangular than usual except in Huperha^ olive 
and yellow scales at base of the AA’ing, the irregular x)atch interrupting the basal black line, which 
forms a diffuse x^atcli between the origins of the cubital and submedian veins. Just beyond is a 
transverse sinuous dark line, curving suddenly iiiAvard on the costa, curving outward on the 
subcostal and cubital A’eins, and curving in again in the submediau sx)ace, then directed obliquely 
outAvard and ending on the inner edge of the wing. From the angle on the submediau fold a 
narroAv interrupted line extends along the internal vein to the black line situated ou the inner 
third of the wing, and Avhich is very sinuous, and ends in a black xmteh both ou the costal and
