60 MR. S. A. NEAVE OX BUTTERFLIES [Jan. 18, 



Chilades mahallakoaena Wallengr. 



I have a long series from many localities which I place under 

 this name with some doubt. The only two typical males were 

 taken on the Alala plateau, ix., and in the Chambezi valley, x. 

 From further north and west, though the females seem indis- 

 tinguishable, the males, instead of being flushed with amethyst- 

 pink as in typical mahallakoaena, do not differ in coloration from 

 the females. 



Chilades trochilus Freyer. 



A common and ubiquitous species. It seems to prefer dry and 

 exposed spots. 



Chilades unigemmata Butler. 



Zizera tmigemmata Butler, P. Z. S. 1865, p. 630, pi. xxxv. 

 figs. 4, 5. 



Two specimens, which, except that they have a very much paler 

 underside, closely agree with the type of this species. They were 

 captured in the upper Lofu valley, viii. and ix. 



Cupidopsis Hippocrates Fabr. 



A scarce insect on the low ground of the Luangwa, valley or the 

 river valleys of Katanga. Common on the high plateau. 



Everes micylus Cram. 



An uncommon insect taken occasionally in the upper Kafue, 

 Lualaba, Chambezi, and Lake Bangweolo districts. 



Neolyoena cissus Godt. 



A fairly common species everywhere. It is on the wing all 

 the year. 



ISTeolyc^ena jobates Hopff. 



I found this an uncommon insect in the Luangwa valley and 

 on the upper Kafue river, but did not meet with it elsewhere. 



Zizera antanossa Mab. 



I found this species of Zizera rare, and only took one specimen 

 on the upper Kafue river, x., and three others on the upper 

 Chambezi river, iv. 



Zizera. gaika Trim. 



This small species is ubiquitous. 



Zizera lysimon Hiibn. 



This species is ubiquitous and much the most abundant of its 

 genus. 



Zizera lucida Trim. 



This species occurs over a wide area and throughout the year.
