ISMENEINM 245 



The larva feeds on Comhretum extensum ; tliis butterfly flies generally in the 

 morning, between 8 and 11 o'clock; its habit is to fly backwards and forwards, with a 

 quick, darting flight, in certain open places in the forest ; it is nearly impossible to 

 catch it on the wing, but it settles at intervals low down near the ground, when it 

 maybe captured. The larva is similar to Ismene fvrgussoni in ever j way ; it feeds 

 on the young pink leaves of the same plant, whereas /. fergussoni feeds exclusively on 

 the tough leaves. It can be distinguished from the larva of the last by the yellow lines 

 at right angles to the lateral yellow line being continued down to the marginal double 

 white line, giving the body the appearance of having a lateral row of large black spots. 

 Length, 40 mm. The pupa is similar in every way to, though smaller than, that of 

 /. fergussoni ; it can be distinguished at once, however, by having a large transparent- 

 looking dirty patch in the middle of the thorax, which the former does not possess. 

 Length, 22 mm. (Davidson, Bell and Aitken.)

Forewing, vein 12 ends on costa opposite upper end of cell, 6 from close to upper 

 end of discocellulars, 5 from a little above the middle ; upper discocellular very minute, 

 middle and lower in an inwardly oblique straight line ; cell more than half the length 

 of the costa, vein 3 emitted from the middle of the cell, 2 from about the basal fourth ; 

 in the female vein 3 is emitted at about one-fourth from the end, and consequently 

 the bases of 3 and 2 are farther apart from each other ; vein 1 distorted downwards 

 near the base in both sexes ; costa evenly arched, apex sub-acute, outer margin 

 convex below the apex, then nearly straight, about as long as the hinder margin,
