African Species of the Genus Acraea. 87 



f. caffra. 



This form its merely acmu with a white discal suffusion in the 

 h.-w. 



f. barberi. 



This form was described by Trimen as a separate species but it 

 cannot be separated from acara. In the ^ the f.-w. apical 

 yellow is less distinct from the ground-colour and the black spots 

 are smaller. The 5 has the f.-w. semitransparent and the basal 

 black is almost obsolete. The h.-w. hind marginal black is 

 almost absent. 



In the example named ab. trirneni by Aurivillius the 

 apical yellow is more pronounced, and the t'.-w. hind mar- 

 ginal black is almost absent. Aurivillius includes under this 

 an example from Rehoboth (German W.Africa) which is now 

 in the Staudinger collection. If this is really harheri then 

 the hypolcucci of Trimen must also be a form of zetes which 

 indeed is highly probable, extremely different in appear- 

 ance though it is. I have in fact only kept hypolcucci 

 separate from zctes because it is so far a unique example 

 and bears no locality. The example labelled harheri in the 

 Staudinger collection differs very little from it. (See 

 remarks under A. hi/polcuca.) 



A. zetes sidamona. 



The Abyssinian subspecies is described by Messrs. Rothschild 

 and Jordan (I. c.) as standing about half way between W. 

 African zeten and E. African zetes acara. In f.-w. on basal side 

 of cellular and postcellular spot is a red mark. The middle 

 portiiin of the discal black band nearly touches the discocellular 

 spot. Six isolated reddish orange submarginal spots larger 

 than in z. zetes. H.-w. black basal area rather more extended 

 than in z. acara. Umlerside with more red than in the other 

 geographical forms, h.-w. marked with white as in acara; 

 yellow submarginal spots all sejiarated from disc by a broad 

 black border except that in area (i which is long. 



The larva and pupa of zetes are described by Aurivillius 

 (/. c.). 



The former is yellowish red, with a shining red head and a 

 dark transverse band in the middle of each segment. The spines 

 aie black and arise from black shining processes. The two 

 dorsal spines of the first segment are somewhat elongated, thf» 

 remainder bent slixlitlv backwards.
