1910.] FROM NORTHERN RHODESIA. 69 



darker coloured than the dry one. Often in very large numbers 

 in mud-holes. 



Eagris lucetia Hew. 



A single specimen of this rare species, taken at Kambove, iii. 

 It is somewhat larger and darker coloured than the type and only 

 specimen in the British Museum. 



Sarangesa astrigera Butler. 



A common woodland species in N.E. Rhodesia, both in the 

 Luangwa valley and on the plateau. Individuals of the dry 

 phase seem to lose all their spots on the upper surface though 

 retaining them on the lower. 



Sarangesa plistonicus Plotz. 



A fairly common species in the Luangwa and Chambezi valleys 

 and the district of Bangweolo, iv.-viii. This species, as well as 

 its allies, has a predilection for very shady spots, as has already 

 been pointed out by Marshall* in the case of 3. eliminata Holl. 

 Jumping on the ground above a hole made by an Ant-bear 

 will often cause clouds of them to issue forth. 



Sarangesa synestalmenus Karsch. 



This species, of which the preceding is perhaps the dry phase, 

 is not uncommon in the Luangwa and Chambezi valleys, i.-v. 



Sarangesa eliminata Holl. 



Only met with in the valleys of the Zambezi and Luangwa, 

 vi.-xii. 



Sarangesa pertusa Mab. 



This species, which seems doubtfully distinct from the preced- 

 ing, occurs sparingly in Katanga at Kambove, and on the Lualaba 

 liver. 



Sarangesa motozi Wallengr. 



A very common species in the Luangwa and Chambezi valleys. 

 S. ophthalmica Mab. appears to be referable to the female of this 

 species. 



Sarangesa motozioides Holl. 



Occurs sparingly in the Luangwa valley, xi.-v., and has much 

 the same habits as motozi. 



Sarangesa subalbicans. 



Sarangesa subalbicans Beth. -Baker, Ann. N. H. (7) xvii. p. 342 

 (1906). 



A single individual of this recently described species was 

 captured at Kambove, iv.
