African Species of the Genus Acraea. 159 



the basal black suffusion extended and the h.-w. hind-marginal 

 black broad and inwardly suffused. Underside correspondingly 

 duller. In extreme forms both wings may be sepia black with 

 a pale ochreous discal bar in f.-w. Abdomeu black with small 

 white lateral spots. 



The brilliant rose-colour of fresh examples of Icuco'pyga 

 is very striking. Neave describes the species as rather 

 rare in the Luangvva Valley, and having the same low 

 flight as A. oncaca, which it somewhat resembles on the 

 wins?.

It is with some hesitation that I maintain this form 

 separate from A. caldarena, as, although there are difterences 

 in the arrangements of the spots I can find no satisfactory 

 difference in the structure of the respective male armatures.. 

 The figures of these would appear to show some difterences, 

 but comparison of the preparation of interriudia with a 

 series of caldarena shows such difterences to be very 

 doubtful. Unfortunately I have only been able to secure 

 a single example for dissection, but since series of pre- 

 parations of the armature of caldarena and its near allies 

 show constant and recognisable difterences, it is at least 

 remarkable that tliere should in this case be no marked 

 distinction. The following description is taken from that 

 by Wichgraf. 



cJ. Expanse 04 mm. Ground-colour uniform dull yellowish 

 brown. F.-w. apical black 7 mm. broad. A very narrow hind- 

 marginal line. The discal spots are three in number (in 3," 4, 5), 

 the middle one being the largest and near to end of cell. These 

 spots lie in a straight line not quite parallel to the edge of the 

 apical black. The spots in 4 and 5 on middle and upper disco- 

 cellulars rounded and confluent. An ovate spot in cell, and at 

 about one-third of the distance from it to the base a smaller 

 linear spot. The spot in 2 lies nearer to the cell than in. 

 rhodesiana and caldarena, and almost equidistant from nervules 

 2 and 3, and the spot beneath it in la, lies nearer to margin. 

 Midway between this and the base a smaller spot. Nervules 

 blackish towards the margin. Base only slightly suffused^
