﻿INSECTS OF EASTERN TROPICAL AFRICA. 283 



Genus Pangonia, Latr. (sens, lat.) 



The flies of this genus are well represented in Eastern Africa, particularly to 

 the south. Though usually to be found only in well wooded areas in the eastern 

 region, they seem to disappear as one approaches the more densely forested 

 western districts and no species has as yet been recorded from Uganda. 



The bite of the female is severe, but they do not, I think, very readily attack 

 man, at least in the case of species of the subgenus Diatomineura. Those that 

 do suck blood also differ somewhat from the Tab aninae in their method of attack, 

 since they usually seem to insert the proboscis without settling, instead of walking 

 over the body of their victim seeking for a suitable spot to bite. 



Pangonia elongata, Ric 



Two males and three females of this striking species were captured in the 

 valley of the Chambezi, Northern Rhodesia, during April 1908. 



Pangonia comata, Aust. 



I was fortunate enough during a single day's collecting at Rabai, near 

 Mombasa, British East Africa, on loth March 1912, to obtain three individuals, 

 all males, of this recently described species.* They were taken in some patches 

 of timber on the side of a wooded hill. All three individuals were captured 

 within a few yards of each other, two at about 10 a.m. and one about 2 p.m. 

 Though the whole neighbourhood was carefully searched, no others could be 

 found. 



Pangonia bubsequa, Aust. 



This species is represented in my collection by a single Q (a paratype) taken 

 near Petauke, in the Luangwa Valley, Northern Rhodesia, 8th April 1905. 



Diatomineura sp. 



Nine females were taken at the beginning of March on the south-east slopes 

 of Mt. Kenya, British East Africa. They were all captured in more or less 

 dense forests and at elevations varying from 6,000 to 7,000 feet. One or two 

 individuals came into the tent, but they were mostly taken at flowers. 



Dorcaloemus compactus, Aust., and var. centralis, Aust. 



This species was taken in some numbers in the Luangwa Valley, Northern 

 Rhodesia, in March 1908 ; in the Ruo Valley, Nyasaland, in April 1910; and 

 also at Voi, British East Africa, in February and March 1911, 1912. In my 

 experience, it mainly frequents the banks of rivers in rather heavily wooded, 

 low-lying country. It does not seem to bite man very readily, but when it does 

 so, the bite is a severe one. In a native, the shin is generally attacked. One of 

 the Voi specimens appears to be intermediate between D. compactus and the 

 recently described D. woosnami a Aust. 



Dorcaloemus sp. nov. 



Two males aud nine females of this species were captured in the Upper 

 Luangwa Valley, North-Eastern Rhodesia, during March, 1908.
