PAPILIONIDJE. 



Larva. " Green, with a yellow collar and brown lichen-like 

 markings. Feeds on Zanthoxylum alatum." (Mackinnon.)

 uniformly green." (MacJcinnon.) 



RHETENOH G-BOUP. 



c? . Fore wing elongate, costa widely arched ; apex produced 

 and somewhat pointed ; termen very oblique ; tornus broadly 

 rounded ; dorsum straight, very short, not nearly .half length of 

 costa ; cell elougate, more than half length of wing. Hind wing 

 elongate, costa and termen form a continuous curve, the latter 

 broadly scalloped, abruptly curved upwards from apex of vein 3 to 

 tornal angle ; dorsum straight ; cell comparatively short ; upper 

 discocellular much longer than middle. $ . Similar, but the posterior 

 portion of the hind wing below vein 4 broadly produced so as to 

 give the appearance of a short broad spatulate tail at apex of 

 vein 4. Antennae slender, not half length of fore wing ; club 

 gradual, elongate, but well-marked ; abdomen comparatively short 

 and not massive. 



A single form known.

J . Upperside black with, in some lights, an obscure dark 

 indigo-blue tint. Fore wing : a series of 

 pale adnervular streaks not extended to the 

 base or quite to the termen but that reach 

 well into the apical half of the cell, and a 

 short slender streak of red rarely absent at 

 the extreme base of the subcostal nervure. 

 In certain specimens also the apical half or 

 interspace 1 a and of the posterior portion 

 of interspace 1 are diffusely white. Hind 

 wing uniform, towards the terminal or 

 outer half sprinkled with bluish scales ; an 

 irregular incomplete white ring at the tornal 

 angle that encloses a black spot bordered 

 above by red. Underside : fore wing similar, 

 but with the pale adnervular streaks broader 

 and much more prominent so that the wing 

 has a general grey appearance ; a patch of 

 dark red at base traversed by the black veins. 

 Hind wing deep indigo-blue black ; a dark 

 red patch at base as in the fore wing, but 

 continued along the dorsum, nearly filling 

 interspaces 1 and 2 ; superposed on the red in the former are two
