Papilio Gelon, Boisd. 



This Papilio is one of the Saipedon group, and is in 

 structure nearest to P. mendana of Malayta Island, 

 Solomon Islands. 



On the upper surface the male is deep black, with a velvety 

 sheen. On the fore wings the type-specimen has three small green 

 dots between the third and fifth median nervules. The hind wings 

 have a green band composed of four longitudinal spots situated as 

 in Sarpedon. On the under side the fore wings are dull black, 

 powdered with yellow scales, and with a metallic-brown sheen near 

 the outer margin ; there are three white spots between the fourth 

 and fifth median nervules, and the costal and median veins are for 

 half their length of a bright green colour. Hind wings chestnut- 

 brown, with darker shading, and crossed by a narrow greenisb 

 white band one-third of the length from the base ; all veins being 

 green at their basal origin. Sbape similar to P. Evemon. 



Feiuale greyish brown on the upper surface. Fore wings with a 

 border of small yellowish spots about an eighth of an inch fron^ 

 the margin. One green spot on the costa about two-thirds the 

 length from the base, and one similar between the costal and 

 median veins. Hind wings with three small oblong blotches of 

 whitish green in the place of the band in the male, the imder side 

 exactly as in the male, only the band of spots on the upper surface 

 of fore wings shows through, and there are two green s^Dots in the 

 place of the band on the hind wings. 



In a second specimen of the male the green band on the hind 

 wings is continued across the front wings, shqwing that this species 

 varies in the same manner as P. semifasciata of Clihia and Japan,
