Body elongate, moderately hairy ; wing.s large, slightly scalloped ; white, with black markings. 

 Head rather small, moderately hairy. 



Eyes prominent, naked. 



Labial Palpi rather short, obliquely porrected, scarcely reaching above the level of the middle of the eyes, 

 extending to about two thirds of the length of the head, remotely apart ; the fii'st and. second joints but slightly 

 clothed with long, erect, hairy bristles ; the terminal joint one third of the length of the preceding, scarcely 

 hairy, slender, acute, and naked at the tip. 



Antennce not half the length of the fore wings, slender, with the joints not very distinct ; terminated by a long 

 and very gradually formed rather slender club, finely carinated beneath on the inner edge. 

 Thorax of moderate size, clothed with woolly hairs, especially in front ; wings large, rounded, and with the outer 

 margin more or less scalloped. 



Fore Wings with the costal margin moderately arched. The apical margin convex, more than two thirds of the 

 length of the costa. Inner margin longer than the apical one. Costal vein moderately swollen at the base. 

 Veins arranged as in Chionobas, except that the discoidal cell of the fore wings does not extend quite to the 

 middle of the wing, which is marked towards the costa with a large black patch, traversed by the disco- 

 cellular veins; the upper of which is very short and almost obsolete; the middle and outer one much longer, 

 forming a ncai'ly continuous curved line, varying, however, in its precise direction ; the middle one emitting 

 a short spur backwards into the discoidal cell, near its junction with the outer one. The median and submedian 

 veins are not dilated at the base. 



JJind Wings large, nearly rounded. Anal margin not incised near its extremity. Costal margin much arched. 

 Costal vein not extending far beyond tlie middle of the costa. Discoidal cell much sliorter than in Chionolms. 

 The upper disco-cellular arising at a short distance from the base of the branch of the postcostal vein, and 

 forming the slightly curved base of the discoidal vein ; whilst the lower disco-cellular is longer than the upper, 

 and united to the tliird branch of the median vein much nearer to its origin than the space between the first 

 and second branches of the latter. 



Fore Legs in both sexes exceedingly minute, concealed amongst the hairs of the breast ; those of the male with 

 the femur oval, compressed. Tibia about as long, broad and compressed, narrowed at the base. Tarsus as 

 long as the tibia, gradually attenuated to the tip, where are several short bristles. Fore Legs of the female 

 shorter than those of the male, but rather broader. The tibia shorter than the femur ; and the tarsus than the 

 tibia ; the tarsus being very short and conical, and apparently exarticulate, with a few bristles at the tip. 



Four Hind Legs rather long and slender, scaly. Tibia of the middle legs much shorter than that of the hind 

 ones : tibia3 armed beneath with two rows of slender long spines ; tibial spurs long and acute. Tarsi very
