African Species of the Germs Acraea. 159 



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

 black broad and inwardly suffused. Underside correspondingly 

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

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

 white lateral spots. 



The brilliant rose-colour of fresh examples of h'ucoinjga 

 is very striking. Neavo describes the species as I'ather 

 rare in the Luangvva Valley, and having the same low 

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

 wing.

It is with some hesitation that I maintain this form 

 separate from A. caklarcna, as, although there are differences 

 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 differences, 

 but comparison of the prejDaration of intermedia with a 

 series of caldarena shows such differences to be very 

 doubtful. Unfortunately I have only been able to secure 

 a single example for dissection, but since sei'ies of pre- 

 parations of the armature of caldarena and its near allies 

 show constant and recognisable differences, it is at least 

 renjarkable that there should in this case be no marked 

 distinction. The following description is taken from that 

 by Wichgraf. 



$. Expanse 64 mm. Ground-colour uniform dull yellowisli 

 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 

 rhodesiaiia 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 .sj^ot. Nervules 

 blackish towards the margin. Base onlv slightlv suffused
