shorter, is proportionally broader, the colour also is very different, for only very 

 brown examples of confusus are known. The examples of A. visci that you have 

 sent me are not immature, for the eyes are black."

DESCRIPTION OF THE ~LKRYM OF TWO SPECIES OF ISMJENE 

 FROM EASTERN AFRICA. 



BY GERVASB F. MATHEW, R.N., F.L.S., F.Z.S., &c. 



Ismene Anchises, G-erst. 



Length, 1^ inch. Velvety-black ; a narrow, white transverse line on anterior 

 part of each segment ; fifth to twelfth segments with two narrow, transverse, orange 

 lines, divided by a broad and intensely black band, having the appearance of a series 

 of rings ; a subdorsal row of linear shaped white spots, and a spiracular row of 

 round white spots ; under-surface, legs and claspers bright claret colour. 



Head cordate, bright brick-red, with seven conspicuous black spots ; ocelli black. 



Feeds in rolled-up leaves of a species of Citrus, wherein, when full grown, it 

 spins a loose network cocoon and changes to a dark brown pupa, covered with a 

 whitish powdery bloom. 



Sab. : Wassin and Zanzibar. 



Ismene Forestan, Cram. 



Length, 1£ inch. Pale greenish-yellow, with minute darker rings, and a broad 

 purple band upon each segment as far as spiracular skinfold, which is conspicuous 

 and yellow ; a linear shaped subdorsal spot in each purple band, and a subdorsal 

 orange blotch upon the twelfth and thirteenth segments ; under-surface paler. 



Head pale red, three round black spots above the mouth, four large linear 

 shaped black spots on forehead, and two on cheeks, the upper one of which is very 

 small. 



Feeds upon a small papilionaceous shrub, drawing the terminal shoots together, 

 and wherein, when full grown, it changes to a pale reddish-brown pupa covered with 

 a whitish powdery bloom. 



Sab. : "Wassin and Zanzibar. 



The above larva? are very handsome. The butterflies appeared in 

 about fourteen days. Both species were tolerably common while I 

 was at Zanzibar from March to June, 1889. They fly very rapidly 

 with a jerky flight in the hottest sunshine, as well as just before 

 sunset. There appears to be a succession of broods, as I found larvae 

 of all sizes at the same time as the perfect insect was on the wing. 



September, 1889.
