PAPILIO. 43 



which it can be distinguished as follows : <S $ . Underside of 

 fore wing : the grey internervular streaks much shorter, formed 

 into a broad transverse discal series which widens considerably 

 towards the costa but posteriorly stops far short of the terminal 

 margin. Hind wing : the upper discal white patch considerably 

 larger than in P. helenus both on the upper and undersides ; the 

 upper spot in interspace 7, which on the underside of the hind 

 wing in P. helenus is generally crescent-shaped, in the present 

 race is always much longer. Below the white patch there are 

 also in some specimens two red crescent-shaped marks in addition 

 to those that are found in P. helenus. 



Exp. 3 $ 118-140 mm. (4-26-5-52").

Messrs. Davidson and Aitken have published the following notes 

 about the larva and pupa : " We got one larva of this on the 

 Tirphal (Xanthoxylon rhetsa ?), a horribly thorny tree leafless in 

 the dry season, the berries of which are used by the natives 

 in currv. The fourth and fifth segments were even more tumid 

 than in P. polymnestor, forming a broad and high hump, nearly 

 flat on the top, and bounded before and behind by rugged ridges 

 of a whitish or pale grey colour chequered with fine brown lines. 

 The anterior ridge ended in a large black and white ocellus on 

 each side, and the whole aspect of the creature from the front 

 had a strikingly grim likeness to the head of some beast or 

 reptile, with heavy brow and angry eyes. Jn other respects 

 no separate description of this larva is necessary. The pupa was 

 distinguishable from that of P. polymnestor, chiefly by the two 

 projecting points on the head being somewhat curved upwards." 



Race mooreanus, Eothschild. " Grey streaks on the underside 

 of the fore wings as in P. helenus dalcsha, Hamps. ; the Naples- 

 yellow scales of the upperside of the fore wings form conspicuous 

 internervular streaks in the outer region ; the white area of the 

 hind wings smaller ( S ) beneath than above ; on the underside of 

 the hind wings there is a complete series of seven subdiscal blue 

 lunules of which the three anterior stand at the outer edge of the 

 white discal marks, and of which the two posterior are situated 

 within the anal and subanal rufous spots." 



Exp. <S 2 124-146 mm. (4-9-5-76").

c? $ . Very closely resembles P. helenus, but differs as follows : 

 Upperside : the upper discal creamy-white spot on the hind wing is 

 much larger and extends into interspace 4 ; in the $ and in some 

 <3 specimens also there is some obscure, diffuse, white scaling 

 below tbat again. Underside : fore wing differs from fore wing
