C. saturnus, yet the upperside of the female is so remarkably 

 similar to that of C. saturnus as to be with difficulty distinguished 

 from the latter without close comparison. 



Mr. Selous notes that nearly all his specimens of this species 

 were taken drinking at the edge of water, but two or three at 

 Lusika Eiver were settled on the branches of a tree. 



66. Chaeaxes gudeeiana (Dewitz). (Plate V. fig. 8, 2 .) 

 (S . Nijmphalis guderiana, Dewitz, Nov. Act. Leop.-Carol. Akad. 

 Naturf. in. p. 200, t. xxvi. fig. 18 (1879). 



This species was founded on three males captured in Angola by 

 Dr. Pogge, and I have noticed (Proc. Zool. Soc. 1891, p. 81) the 

 receipt of a male from Mashunaland and of sixteen males from 

 the Ambuella Country not far from 16" S. lat. Mr. Selous collected 

 1 example at Fmtali, no fewer than 30 at Mineni Valley, and 

 8 at Lusika Eiver, and of these 5 each from the second and third 

 locahties were females ; nearly all were taken in March, but one 

 on Pebruary 28th and eight between April 1st and 25th. 



As guderiana is unquestionably a member of the ephyra and 

 eihalion group of Charaxes, it is very unexpected to find the female, 

 as in the case of C acTicemenes just mentioned, on the upperside 

 closely resembling C. saturnus, and so differing widely from the 

 aspect of her nearest congeners.

Fuscous, tvith a common ocJire-yelloiv cliscal hand {in fore wing 

 moderately hroad hut macular and more or less deeply cleft hy down- 

 ward traversing har of ground-colour, in hind iving continuous, short, 

 and much narroiver inferiorly) ; bases didl ferruginous-ocJireous. 

 Fore wing : terminal discocellular spot ochre-yellow instead of 

 white ; commencement of inner series of spots forming ochre- 

 yellow discal band represents the conspicuous outer costal wliite 

 spot in male ; six spots of incurved outer series of discal band 

 represent the submarginal series of small bluish-white spots in 

 male — in one example only, the lowest spot of this outer series is 

 confluent, between 2nd and 3rd median nervules, with a large spot 

 of the inner series ; hind-marginal series of spots ferruginous- 

 ochreous instead of white (the lowest and largest spot, however, 

 more or less whitish internally), enlarged, often confluent into a 

 submacular border. Hind wing: discal band simple, whitish 

 yellow on costa and on inner edge, much indented by ground- 

 colour on both sides inferiorly, where it is also more or less tinged 

 and edged with metallic bluish or greenish scales; submarginal 

 series of white, on both sides metallic-bluish or greenish bordered, 

 lunules, much like that in male ; upper four lunules of hind- 

 marginal series ochre-yellow instead of white, the remainder to 

 anal angle metallic greenish or bluish with ochre-yellow centres as 

 in male ; tails much longer and broad, especially that at end of 3rd 

 median nervule, which is subspatulate instead of acute. Undee-
