African Species of the Genus Acraea. 307 



irregularly blackish at base, extending into cell and below 

 median, with slight blackish scaling at anal angle. Thorax 

 black, with pale spots, abdomen black above, yellowish beneath, 

 and bearing small white lateral segmental spots. 



9 resembles ^ . 

 f. transita. 



This form has the tyjiical basal red of the f.-w. replaced by a 

 black suffusion and the h.-w. red is replaced by white, yellow 

 or orange. It is liable to occur in both sexes. 



Almost every grade of intermediate may occur between 

 the forms above described. Some time after I had 

 decided that Miss Sharpe's A. htimilis was a form of 

 Hewitson's orestia a series of specimens was received at 

 Oxford from Dr. G. D. H. Carpenter, wlio had bred them 

 on Damba I. These contain both the typical red and the 

 f. transita, and taken in conjunction with another series 

 captured in the 'J'iriki Hills by Dr. C. A. Wiggins, con- 

 taining all three forms, fully confirm my conclusion. The 

 larva is described by Dr. Carpenter as having been 

 mistaken by liim for that of A. alciope* from which I 

 gather that the resemblance is extremely close.
