<?. The nj)per scales and most of tlu^ hairs of the forewing are deep fei rnginous, 

 except at costal and distal margins and upon veins, which are olive; two interrupted 

 antemedian bands, and two discal series of Innules followed by a series of postdiscal 

 spots, are black. There are no ferruginous scales on the underside of the wing, but 

 some of the thoracical hair-scales and those at the lower edges of the abdominal 

 tergites and on the legs are also more or less of the same peculiar colour. Onr 

 specimen has the antenna less pale, the forewing, thorax, and legs more ferruginous, 

 the posterior angles of both wings better indicated, the distal margin of the 

 hindwiug less convex, and the blackish olive band of the same wing more straight 

 than cue of Mr. Schaus's specimens. 



Tenth tergite (PI. XXII. f. 1(5) slender, lanceolate, j)ointed, slightly curved 

 downwards, extreme end more so, mesially carinate below ; sternite also long, 

 broader than the tergite, gradually narrowed, sinuate, the angles acute and curved 

 upwards. Clasper large, sole-shaped ; harpe irregular, ending in an obli(iuely 

 sinuate process, sharjily pointed ; at the dorsal side of the sinus there is a small 

 tooth, between wliich and a more jiroximal, large, triangular tooth there is another 

 sinus. Penis-siieatli with a long pointed jmicess which curves proximad and 

 laterad; i)enis-funiiel simple.
