122. Papilio pausanias Hew. (1852). 



Pajiilio pausaidas Hewitson, Tr. Eni. Soc. Land. (2). ii. p. ii. t. G. fig. 2 (1852) (British Guiana ; 

 Ega). 



c??. Abdomen with broad huffish lateral streak. Forewiug proximaily and 

 nearly the whole upper surface of the hindwing metallic greenish blue ; a straw- 

 or primrose-yellow area on forewing, consisting of a large cell-patch and two large 

 discal patches R' — M-, there being often a small additional spot before R^ and 



another behind M-. Hindwing without discal markings, bnt with a row of more 



or less distinct white curved submarginal bars ; shape of hindwing variable, distal 

 margin (apart from dentition) often straight, especially in female. 



Underside brown, without distinct black cell-streaks ; hindwing with three red 

 basal spots which are often developed to streaks ; a row of red postdiscal lunules, 

 also often produced basad, forming more or less distinct streaks. 



Scent-organ absent, vein SM- being clothed with metallic blue scales, only a 

 few of the scales being greyish. 



Genitalia not essentially different from those of P. protodamas ; the dorso- 

 ventral dentate ridge of the harjjc ventrally a little more curved, apical lobe a little 

 larger, and the teeth beneath this lobe rather more numerous. 



Early stages not known. 



Hub. Costa Rica southward to Bolivia and the Brazilian province of Goyaz. 



Three subspecies. 



a. P. jjausaniiis prashuis subsp. nov. 



c?. Similar to clcomhrotiis. I'pperside of wings more green in tint, this 

 metallic colour also more extended, the costal area of the hindwing being hardly 



k'ss metallic green tlian the disc. Forewing rather shorter ; discal patches 



longer, reaching three-fourths the way from cell to distal margin. Hindwing : 



white submarginal spots minute, upper ones vestigial, practically absent both above 

 and below ; red basal sjwts of underside smaller than in cleombrotus.
