52 PAPILIONIDJ. 



514. Papilio polymnestoroides, Moore (Iliades), Leo. Ind. v, 1001- 

 1903, p. 202, pi. 451, figs. 1, 2, rf $ . 



d 1 $ . Differs from P. polymnestor, Cramer, as follows : 

 $ Upperside, fore wing : the adnervular streaks on outer portion 

 of wing not so broad. Hind wing : basal portion to apex of cell 

 black, beyond this a series of adnervular blue streaks that do not 

 reach the outer margin, each pair coming to a point outwardly on 

 the veins ; these are followed by a series of very obscure large 

 subterminal spots of a shade darker than the ground-colour in 

 interspaces 1 to 4. Cilia black, touched with white in the inter- 

 spaces. Underside opaque black, a patch of dark red at base of 

 wings. Fore wing as on the upperside but with the greyish-blue 

 streaks broader. Hind wing with a discal and a subterminal 

 series of large oval black spots, the former surrounded by a broad 

 grey margin ; tornus narrowly i-ed. Antennae, head, thorax and 

 abdomen as in polymnestor. 5 . Upperside : fore wing with pale 

 greyish adnervular streaks on outer half narrower than \n polym- 

 nestor ; base of cell entirely filled with a broad red streak ; a very 

 short streak above base of vein 1. Hind wing : ground-colour 

 dull velvety brown, with discal, subterminal and terminal rows of 

 black spots as in polymnestor, only more obscure ; the medial area 

 with a series of broad blue outwardly pointed adnervular streaks 

 as in the c?; the black spot at tornns bordered with grey. Under- 

 side : differs chiefly from the underside of polymnestor in the grey 

 internervular streaks on the outer portions of the fore wing that 

 are longer and produced to the bases of the anterior interspaces 

 inwardly and outwardly almost to the terminal margin ; on the 

 hind wing the discal series of spots are closer to the subterminal 

 series. 



Exp. S $ 127-148 mm. (5-5-86"). 



Hab. Recorded only from Eastern Bengal and Assam. 



I have provisionally followed Moore in keeping this form 

 distinct from P. polymnestor, but it is probably only a rare aber- 

 ration of that insect.

c? 5 alike. Fore wing somewhat elongate ; costa arched, apex 

 produced but rounded ; termen oblique, slightly concave ; tornus 

 rounded ; dorsuni straight, about half length of costa ; cell broad 

 and long, more than half length of wing. Hind wing : costa and 

 termen to apex of vein 2 form one long continuous curve, the 

 termen broadly scalloped ; dorsum to tornal angle straight, below 

 the latter the termen emarginate ; cell narrow, comparatively 

 short ; subcostal vein and upper discocellular subequal. J with a 

 white costal streak on the upperside of the hind wing. Antenna 

 not half length of fore wing, slender; club elongate, gradual, 

 slight.
