S ? . Basal patch of modified scales at hinder raargin of forewing, on under- 

 side, limited in front by SM-, not extending costad beyond this vein as in Eule/jis, 

 Charaxes, and Euxanthe. Stalk SC^'*-'* of forewing longer than in Ckaraxvs. D' 

 of hindwing very thin, reaching M between M' and M^, being much closer to M^ 

 than to JP. Mid- and hindtibia not spinose on upperside. Foretibia with apical 

 spines. 



(?. Tenth abdominal tergite produced into a simple, long, curved, pointed 

 hook ; tenth sternite long and slender. Ninth segment larger than in Charaxes, 

 covering ventrally the bases of the claspers. The latter with ventral apical hook. 

 Penis-funnel absent. Ape.\ of penis-sheath more or less densely dentate. 



?. Seventh abdominal segment with a divided mesial tubercle at apical margin. 



Early stages not known. 



Ha/). West Africa : Sierra Leone to Angola, eastwards to Uganda. 



Fonr species, which are all closely allied in pattern and in shape. However, 

 while decius, violinitens, and ii.ssheri are sexually strongly dichromatic, the sexes of 

 publius are nearly the same in colour. There is no black line on vein W of the 

 hindwing (which closes the cell), and on the forewing bar D' is seldom indicated. 

 The outer half of the underside of the forewing, the distal margin excepted, is 

 densely irrorated with short transverse bars, which are not homologous to the 

 regular series of bars found in ('/lantjes. This irrorated area is limited distally 

 by a series of more or less indistinct bars, which correspond to the snbmarginal 

 series of Charaxes. On the hindwing the irroration is repeated, bnt here we find 

 distinct submargiual spots. 



The hindwing is in outline similar to that of Charaxes varanes, having one 

 obtuse tail.
