(S. Tiie ujiper scales and most of tiie hairs of the forewiiig are deep ferruginous, 

 except at costal and distal margins and u])on veins, wiiich are olive; two interrupted 

 antemedian hands, and two discal series of Inmiles followed by a series of postdiscal 

 spots, are b];ick. There are no ferruginous scales on tlie 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. Our 

 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 

 hindwing less convex, and the blackisii olive band of tlie same wing more straight 

 than one of Mr. Schaus's specimens. 



Tenth tergite (PI. XXII. f. 1(5) slender, lanceolate, pointed, 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 ; harjjc irregular, ending in an obliquely 

 sinuate })rocess, sharply jiointed ; at the dorsal side of tiie sinus there is a small 

 toolh, between wliich and a more ]iroximal, large, triangular tooth there is another 

 sinus. Penis-sheath with a long jmiiited jirocH'ss which curves proximad and 

 laterad ; penis-funnel simjile.
