NYMPHALID^. 



the discoidal cell, which is not closed, the lower disco-cellular vein being obsolete ; third branch of the median 

 vein regularly arched. 



Hind Wings subtriangular. The costal margin rounded. Apical margin entire, slightly angulated at the 

 extremity of the third branch of the median vein. Anal groove very large, with the anal angle acute. Pre- 

 costal vein erect, curved outwardly at the extremity. Discoidal cell open, the disco-cellular vein being obsolete. 



Fore Legs of the male moderately long, pectoral, not very woolly, and but slightly feathered. Tarsus not more 

 than half the length of the tibia, exarticulate, and destitute of claws. Fore Legs of the female very slender ; the 

 femur and tibia of equal length, the former finely hairy beneath. Tarsus two thirds of the length of the tibia, 

 slender, scaly ; the tip rather compressed, oblique, and armed with three pairs of short spines near the tip, 

 indicating the intermediate joints. 



Four Hind Legs moderately long and robust, scaly, the intermediate pair longer than the posterior ; similar in 

 structure to those of Prepona, Smyrna, &c., but with the spines of the tibite and tarsi stronger. 

 Abdomen small, conical. 



The type of this genus is remarkable for the extraordinary robustness of the body, agreeing in this respect, as well as in its habits, 

 with Prepona, but destitute of the metallic markings of the latter genus. The wings are also more strongly falcate, and the veins 

 arranged nearly as in Pandora, except that the discoidal cell is open in all the wings. The under side of the wings is richly marked 

 with shades of dark orange and brown, the basal half of the wing with more decided fascia?, divided by slender black lines, the outer- 

 most of which is elegantly glossed with purjile, and the submarginal portion of the wing powdered with white scales, as in Siderone. 



We are only acquainted with a single species belonging to the genus.

Nymphalis p. God'. 



Body robust; wings of the males generally with a splendid purple gloss, the anterior emarginate in tlic middle of 



the apical margin. 

 Head of moderate size, larger in tlie males than in tlie females, hairy, slightly tufted in front. 



Eyes prominent, naked. 



Antemice about equal to three fifths of the length of the fore wings, nearly straight ; terminated by a rather strong 

 elongate-ovate club, compressed and delicately keeled along the inside. 



Maxillce long and spiral. 



Labial Palpi porrected obliquely, the tip rising nearly to the level of the top of the eyes. Inner surfaces parallel, 

 nearly united together, so as to form a conical beak nearly as long as the head, thickly clothed with short 

 scales ; the base beneath, the inner surface of the middle joint and the terminal half of the upper surface, 

 furnished with elongated hairs; the basal joint very short; second joint very long, slender, and curved; the 

 third not longer than the basal joint, elongate-conic, pointed at the tip. 

 Thorax robust, subovate, very woolly in front and behind. 



Fore Wings elongate-trigonate. Anterior margin moderately arched ; apical angle subtruncate. Apical margin 

 nearly more than two thirds of the length of tlie anterior, slightly scalloped, and more or less emarginate in the 

 middle. Inner margin nearly straight, a little longer than the apical one. Veins very strong. The costal 

 one extending to the length of two thirds of the costa from the base. Postcostal vein with the first branch 

 arising a little before tlie anterior extremity of the discoidal cell ; second branch arising at one third of the 

 length of the wing, just before or exactly at the extremity of the cell ; tliird branch arising just beyond the
