1910.] FROM NORTHERN RHODESIA. 61 



but I did not find it common anywhere except in the Ohambezi 

 valley and Lake Bangweolo district. 



Fam. Pieeidj;. 



PsEUDOPONTIA PARADOXA Feld. 



I found this peculiar insect not very rare on the Lufupa and 

 Lubudi rivers, x. It frequents dense forest and the thick bush 

 on stream -banks, etc., and much resembles Leptosia medusa on 

 the wing. 



Leptosia medusa Cram. 



This species is ubiquitous, but not very abundant anywhere. 

 It frequents forest and thickets chiefly on low ground, and it is 

 perhaps most common in the dry season. 



Herp^enia eriphia Godt. 



Occurs everywhere and at all seasons, but is nowhere very 

 abundant. Has a strong and active flight. 



Mylothris agathina Oram. 



A ubiquitous species and much the most abundant of its 

 genus. 



Mylothris rUppelli Koch. 



Common everywhere, except in the Luangwa valley where it 

 is somewhat scarce. 



Mylothris yulei Butler. 



I took a small series of this species on high plateau country 

 during the dry season. Some specimens, especially from Katanga, 

 have a considerable amount of orange flush at the base of the 

 primaries and a rather different apex. They perhaps represent a 

 distinct species. 



Mylothris rubricosta Mab. 



This species occurs over a wide area in localities suited to it. 

 It frequents open marshy ground and river banks when not 

 obscured by timber, etc., and has a rather weak flight. 



Appias epaphia Cram. 



This species occurs everywhere and at all seasons. It is nowhere 

 very abundant, the females being especially scarce. 



Belenois gidica Godt. 



A common insect everywhere, and may often be seen in 

 hundreds at mud-holes. The dry season form abyssinica Lucas 

 is, during its season, more common if anything than the wet 

 phase.
