RHOPALOCAMPTA. 31 



This is a brown Butterfly, measuring two inches in expanse; 

 the hind-wings are covered with yellowish hair, and bordered 

 with black ; towards the anal angle is a lobe, edged with orange. 

 On the under side of the hind-wings is a broad transverse white 

 band, interrupted above the inner-margin. It is common in 

 many parts of Africa. The larva is pale yellow, banded with 

 purplish and crimson, and feeds on Robinia pseudacaria. The 

 pupa is greenish, covered with whitish efflorescence, and spotted 

 with black. 



There are several very remarkable Butterflies of this genus 

 found in West Africa. One is R. bixce (Linnaeus), a Butterfly 

 expanding from 2 to 2^ inches; the wings are purplish-blue 

 above, and the hind-wings are lobate at the anal angle ; the 

 head is streaked and spotted with white beneath ; the pectus 

 is clothed with orange hair, and the hind-wings are marked 

 beneath with a pure white spot, running from the sub-costal 

 nervure to about the end of the cell, and tapering towards the 

 inner-margin. 



Another is R. iphis (Drury), the largest of the Hesperiidce^ with 

 which we will conclude our notice of the Family. The wings 

 are long, and measure four inches in expanse ; the fore-wings 

 are slightly rounded off at the tips, and the hind-wings project 

 slightly at the anal angle. The body is black, with the palpi 

 and the tip of the abdomen beneath crimson. The wings are 

 blue-black in the male, but with brassy-green reflections to- 

 wards the hind-margins, and with the tip of the fore-wings nar- 

 rowly edged with orange in the female. The under side is of 

 a yellower brassy-green than the upper. 



This species sits with its wings erect, and likes the company 

 of small parties of Euphadra eupalus (Fabricius), and is fre- 

 quently seen sipping water with them.
