Body robust but small ; wings very large, rounded, ocellated beneath ; prediscoidal cell of hind wings small ; hind 

 wings of the male with a very slight canal, and a small tuft of hairs near the anal margin, opposite the middle 

 of the abdomen. 

 Head moderately large, hairy, with a conical tuft in front. 



Eyes large, naked. 



Antenna slender, scarcely more than one third of the length of the fore wings, terminated by a very slender 

 and gradually formed club. 



Labial Palpi rather large, porrected obliquely, moderately hairy; the tip rising above the level of the top of tlie 

 eyes, and advanced in front nearly to tlie length of the head. Middle joint with a tuft of hairs on the bacic, 

 resting on the sides of the conical tuft of the face. 

 Thorax robust, hairy. 



Fore Wings very large. Costal margin much curved ; apical angle strongly rounded. Apical margin straight or 

 very slightly concave, and but slightly waved, not much more than two thirds of the length of the costal margin ; 

 posterior angle rounded. Inner margin somewhat dilated and convex, in the males. Costal vein extending 

 nearly to two thirds of the length of the costa. Postcostal vein with its first and second branches arising 

 about the middle of the length of the wing, before the anterior extremity of the discoidal cell ; third branch 

 arising at about three fourths of the length of the Aving ; fourth branch arising a little beyond, and extending 

 to the tip of the wing. Anterior disco-cellular vein distinct, about as long as the posterior, very oblique, and 

 slightly curved. Middle disco-cellular vein twice or three times the length of the anterior, very much curved, 

 its outer half being nearly longitudinal, whilst the posterior disco-cellular is nearly transverse, closing the 

 discoidal cell transversely, at about two thirds of the length of the wing, uniting with the third branch of the 

 median vein at about the same length from its base as exists between tiie first and second branches, the third 

 branch being acutely angulated, the apical portion beyond the angle being nearly straight. The submedian 

 vein is curved in the male, following the outline of the inner margin of the wing. 



Hind Wings large, elongate-ovate, more or less entire, or but slightly waved along the outer margin ; anal 

 angle rounded off. Precostal vein short and fi)rked. Costal vein extending nearly to the outer angle. 

 Postcostal vein forming a small prediscoidal cell between its base and that of the costal vein ; its first branch 

 arising at a considerable distance from the base. Anterior disco-cellular forming the curved base of the 

 discoidal vein, its basal portion being very much curved. Outer disco-cellular vein not more than half the 

 length of the anterior, transverse, closing the discoidal cell at about half the length of the wing. The anal 

 margin fui-nished, in the males, witli an elongated narrow channel, and a small tuft of hairs. 



Fore Legs of the male of moderate length. Tibia and tarsus very thickly clothed on the outside with loose hairs. 

 Tarsus three fourths of the length of the tibia, simple. Fore Legs of the female thicker, but not much longer, 

 than those of the male, moi'e thickly clothed on the outside with shorter hairs, especially at the tip of the tibia 

 and the tarsus, the joints of which are distinct and spined at the tip within, the tii) oblique. 

 Fonr Hind Legs long and strong. Tibia shorter than the femur, strongly signed in rows. Tibial spurs strong. 

 Tarsus as long as the femur, with numerous rows of fine spines. Claws rather small, very much curved and 

 acute. Pulvillus and its appendages small. 



Caterpillar elongate, rather thickest in the middle; head shield-like, and armed with several horns; 



each of the middle segments of the body with an erect spine ; body terminated by two elongated conical 



appendages. 

 Chrysalis thick, with an obtusely conical point on the back of the thorax case.
