CETHOSTA. 



151 



scarcely, if at all, longer than those of the male. Femur and tibia of about equal length, 

 nearly cylindric, the latter slightly spiny within. Tarsus shorter than the tibia, five-jointed ; 

 the first joint nearly double the length of the rest combined, largest towards the apex ; the other 

 joints transverse, successively shorter ; all the joints except the fifth armed on each side at the 

 apex with a stout spine, covered more or less by a tuft of stiff hairs at the base of the following 

 joint. 

 Middle and Posterior Leys with the tibiae rather shorter than the femora, spiny ; the spurs distinct. 

 Tarsi about equal in length to the tibia?, very spiny ; the spines above slender, much stronger at 

 the sides and below, forming three well defined series along the sole of the foot. First joint 

 equal to the rest combined ; second, third, and fourth progressively shorter, and slightly thicker; 

 fifth longer than the second, rather dilated ; the spines, especially the lateral ones, longer than on 

 the other joints. Claws elongate, grooved below, lobed at the base, acute, but little curved 

 except at the base and apex. Paronychia and pulvilli wanting or rudimentary. 

 Abdomen subcylindric, shorter than the inner margin of the posterior wings. 



Larva and Pupa unknown. 



Cethosia differs from the preceding genus, to which Godart united it, in the form of its middle and posterior tarsi, 

 which somewhat resemble those of Eurycus. The antennae have the club of different form, and the wings are 

 proportionably much broader. 



It is allied at once to Cokenis, Agraulis, and Argynnis, and thus cannot be placed anywhere in a linear series 

 without interrupting what would seem to be the natural order of the genera. 



The typical species are distinguished by the great beauty of the under surface of the wings, which is generally of a 

 buff or light red colour more or less banded with white, and marked by numerous series of short black bands and spots ; 

 the outer margins being black, marked with a deeply zigzag white line. The upper surface is of some shade of red in 

 the males, and mostly so in the females ; but in those of one or two species it is white, marked with black dots, more 

 or less deeply bordered with black, which sometimes occupies the greater part of the anterior wing. Cethosia 

 Leschenaultii offers above a remarkable variation from the type, being above of a deep satiny black with the outer 

 margin of both pairs of wings bright fulvous, and might thus at a little distance be mistaken for Argynnis Diana. 

 Cethosia Lamarckii has the upper surface black with the base orange, and the disc with beautiful blue reflections. 



Of the habits of this genus we know nothing. Its geographical range extends over Southern Asia, the Asiatic 

 Islands, and part of Australia. The species figured was taken at Sarawak by Mr. H. Low, now Colonial Secretary 

 at Labuhan.
