DESCRiFflON : "Male, difTers from P. darlisa in having fully the basal half (including 

 the same extent of the abdominal area in the hindwing) of both wings devoid of markings, the 

 submarginal and discal series of spots alone remaining ; these two series of spots are bluish- 

 white in the fornving, and of a beautiful straw-yellow in the hindwing ; they are, in fact, 

 of the same colour, size, and shape as in P. darlisa ; but the inner of the latter two series is 

 closer to the outer, which is placed at the same distance from the external margin of the wings. 

 Both wings are also somewhat narrower than in P. darlisa, thus approaching those of the 

 typical species ; and the hmdiiing is furnished on the basal half, between the median and 

 submedian nervures and in the discoidal cell, with a thick and conspicuous fnrry clothing of 

 rich dark fuscous setre exactly matching the dark ground-colour of the wing and the abdomen 

 of the insect in shade, which setose clothing is so scantily developed as to be quite inconspi- 

 cuous in P. darlisa and P. lisarda. The whole body, too, but especially the abdomen, is 

 much darker-coloured than in either of them. Shadowy traces of the lost spots are faintly 

 discernible on the foreiving." {Wood-Mason, 1. c.) 



The type specimen was obtained by Captain C. T. Bingham, after whom it is named, 

 and is now in the Indian Museum, Calcutta ; he has presented other examples to the British 

 Museum. The figure showing both sides is taken from the type.

•' Body, robust ; abdomen, small ; wings, elongated. Head, broad, hairy, without a 

 frontal tuft. Eyes, large and naked. Palpi, compressed, parallel, not forming a conical 

 projecting beak, directed upwards. The terminal joint nearly erect, and elevated to the 

 level of the top of the eyes, thickly clothed with short scaly hairs, and with longer loose 

 hairs on the whole of the front surface of the middle joint, and with a tuft of hairs at the 

 extremity of the upperside ; terminal joint small and conical. Antenita;, half the length of 

 the forewing, nearly straight, terminated by a very long and slender, gradually formed club, 

 slightly grooved on its interior lower surface. Thorax, robust, thickly clothed with short woolly 

 hairs, and marked with transverse bars of different colours. Abdomen, small, rather slender. 

 Forewing, elongate triangular. Costa slightly arched ; outer margin three-fourths of the 

 length of the costa, scarcely emarginate, and slightly scalloped ; inner angle rounded ; 

 {pinner margin'\ not much more than half the length of the costa, very slightly emarginate. 

 Costal nervure strong, and extending more than two-thirds the length of the wing ; snbcosial 

 slender ; its first branch arising at the distance of one-fourth of the length of the wing from 

 the base ; the second branch arising at two-fifths of the length of the wing, beyond which 

 for a short distance the subcostal nervure is a little defiexed, it then runs parallel with 

 the costa, until the branching off of the third branch at the distance of two-thirds from 

 the base of the wing ; which is immediately followed by the branching off of the fourth branch. 

 The uf'per disco-cellular nervule is almost obsolete, it branches off from the subcostal nearly 

 at half the length of the wing, just beyond the origin of the second branch of the subcostal ; 

 middle disco-cellular short, straight, and rather oblique, being directed from the side of the 

 costa towards the base of the wing ; lower disco-cellular much longer, obliquely arched, 

 so that it closes the discoidal cell by uniting with the median nervure close beyond the 

 origin of its third branch (being preceded on the upperside of the wing by a slender, arched, 

 black line, dividing the second white subcostal patch into two irregular-shaped portions). 

 ./»/^a'w« w^/w/;-!? strong ; its third branch strongly angulated at about one-third of its length 

 from its origin. Submedian nervure considerably curved, IIindwing, subquadrangular
