African Species of the Genus Acraea. 157 



of ground-colour. End of cell, end of area 2, and all of la, lb, 

 and Ic, except extreme base, scaled with rusty red. Black spots 

 as follows : — One in 9, one in 8, two in 7, the second followed 

 by a spot in 6, and 5 all parallel to the apical margin, one in 4 

 close to cell, beneath it and nearer margin one in 3, one in 2 

 touching median and nervule 2, beneath it one in Ic, and one 

 in lb level with that in 2. Also two in cell, a dot on the middle 

 discocellular, a basal and a subbasal in Ic, lb, and la. 



Head, thorax, and abdomen black with a few whitish marks. 



In spite of the difference in locality Neave's lactea 

 appears to be the same species as Suffert's dioge7ies, the 

 type of which I have carefully examined. The cotype of 

 lactea in the Oxford collection differs only in its larger 

 size, its fresher condition, and in the greater extent of red 

 on the underside of h.-\v. So far as I am aware there 

 are only three examples known, all $ $, and until more 

 material is available it is difficult to decide the true 

 affinity of this form. The genital plate is, as will be seen 

 from a reference to the figure on Plate XVI, of a most curious 

 formation, unlike that of any other species which I have 

 had the opportunity of examining. The portion surround- 

 ing the opening of the bursa copulatrix consists of a 

 heavily ridged mass of chitin, thickly set with minute 

 spines or teeth, and resembles in this respect the mem- 

 brane surrounding the male organs in i^eriphanes. It 

 bears no resemblance, however, to the $ plate in peri- 

 phanes, which is of comparatively simple structure.*

 to think tliat A. diogenes will ultimately prove to be a $ of A. 

 yiiiUemei, or, if that form be really distinct from A. acut'ipennis, 

 ihen a $ of the latter.
