" Labial ^)(t?2>'' rather slender, obliquely directed upwards, but not reaching above the middle of 
the eyes ; the tips horizontally porrected and slightly incurved, clothed with closely ad- 
pressed scaly hairs, with longer hairs at the base beneath, and towards the extremity of 
the second joint on the upperside ; the terminal joint very short and obtuse. 
" Thoeax robust ; collar often variously coloured ; dorsum often marked with white spots ; meta- 
thorax large, deeply grooved down the middle, finely hairy. 
" Fore wings large, subtriangular. Anterior margin rounded ; apical angle rounded. Outer 
margin three fifths of the length of the anterior, slightly convex, straight, or but very 
slightly concave, and slightly scalloped. Inner margin nearly straight, three-fourths of 
the length of the anterior margin. Costal vein strong, reaching to the middle of the 
costa : subcostal vein with its first branch arising at about one fourth of the length of the 
wing, followed immediately by the second branch ; third branch arising at about two thirds 
of the length of the wing, and extending to the apex; fourth branch arising at about five 
sixths of the length of tlie wing, extending below the apex ; the terminal portion of the 
vein rather deflexed. Upper discocellular vein almost obliterated, arising from the sub- 
costal at one third of the length of the wing ; middle discocellular very short, curved, 
forming the base of the lower discoidal vein ; lower discocellular obsolete in the typical 
species, the discoidal cell being open. In others it is, however, distinct, although very slender, 
arising from the extremity of the middle discocellular, which is in such species curved 
obliquely towards the base of the wing, and joining the median vein close to the origin of 
the third branch. 
" Hind ivings subtriangular ; costal margin rather rounded ; outer margin rounded, and more 
strongly scalloped. Precostal vein strongly curved outwards ; costal vein arched, and 
extending to the outer angle. Subcostal vein branching very near to its base, and also 
emitting the upper discocellular very near to the base of its branch. Upper discocellular 
forming the base of the discoidal vein. Lower discocellular obsolete. 
" Fore legs of the male small, pectoral, finely hairy. Tibia not so long as the femur. Tarsus 
rather more than two thirds of the length of the tibia ; when denuded it is cylindi-ical, 
simple, exarticulate, and destitute of claws or spines, as is also the tip of the tibia. Fore 
legs of the female rather longer and thicker, scaly ; tarsus with well-developed joints ; the 
first being half the length of the tarsus, without spines at the tip beneath ; second, third, 
and fourth joints with strong short spines on the underside. 
" Four hind legs moderately long ; tibia spined beneath, tibial spurs strong ; tarsi more thickly 
spined beneath, the spines arranged in rows. Claws and their appendages of the same 
form as in the allied genera. 
" Abdomen moderately robust, often party-coloured, especially at the base." (Westivood, I. c.)

' Upperside smoky-black, fore wings with a green gloss in some lights. Fore wing with three 
oblique white ovate spots from subcostal vein, one third from the apex ; two white spots in 
middle of the wing, the upper one very small, and two white spots on middle of posterior
