Caricea tripunctiventris, sp. n. 



Male. — A smaller species than either of the preceding 

 two, with hyaline wings, the fore tibia not pale yellow at 

 base, the abdomen almost cylindrical and with paired spots 

 and a fuscous median vitta on dorsum black. The arista has 

 shorter hairs than in the last species, the antennae extend 

 farther towards niouth-margiu, the third segment is slightly 

 pointed at apex above. In other respects the head is similar 

 to that of semialba. The hypopygium is larger tiian in that 

 species, being slightly knob-like, the abdomen is not com- 

 pressed, and the outer cross-vein of wings is about one-third 

 from apex of discal cell, which is much closer to apex than 

 in semialba. 



Length 35 ram. 



Tj/pe, Mt. Mlanje, Nyasaland, 16. vi. 1913 (S. A. Neave). 



A female which is marked, as is the male, may probably 

 represent another species. The arista has longer hairs, the 

 sterno-pleural bristles are all long and strong, and the inner 

 cross-vein is but little beyond middle of discal cell, while 

 the outer one is even farther from apex of fifth vein than in 

 semialba. 



Locality, Durban, Natal (F. Muir). 



Caricea longiseta (Stein). 



Differs from all the preceding species in having the femora 

 and tibiae yellow, only the extreme apices of the hind 

 femora being black, and the coxae are yellow. The antennae 

 are black, and palpi yellow. Thorax indistinctly vittate. 

 Abdomen marked w ith a series of central spots and paired 

 lateral s[)ots black. Longest hairs on arista about as long 

 as third antennal segment. Anterior sterno-pleural bristle 

 long and strong ; median fore tibial bristle very long, 

 median hind tibial bristles very long and transversely 

 placed. 



One male from Sierra Leone differs in having the apex of 

 third antennal segment and all of fore coxae except extreme 

 bases yellow. 



Length 5 mm. 



I iiave before me a series of specimens from Ashanti, 

 Sierra Leone, Southern Nigeria, Uganda, Northern Nyasa, 

 and Durban, Natal.
