HABITAT. 



My specimens were taken in a small district lying along 

 both banks of the lower stretches of the Katumbela River, 

 which empties into the sea near the port of Benguella, Portu- 

 guese West Africa. Mr. Austen writes,* "The above speci- 

 mens are of especial interest as being the first recorded ex- 

 amples of any form cf Gl. palpalis from Portuguese West 

 Africa, and as showing that the range of the species in ques- 

 tion, which has recently been stated by Laverant to occur at 

 Sengaleam (about thirty miles from Cape Verde), extends 

 at least as far south as 12 30' S. lat. In all probability Glos- 

 sina palpalis wellmani will eventually be proved to exist right 

 down to the Cunene River, the southern border of Angola, if 

 not further." Mr. Austen also wrote me suggesting that I 

 try to establish the southern limit of the new fly. I have accord- 

 ingly kept a sharp lookout for it and have made further in- 

 quiries concerning it with the meager result that I have received 

 a single badly-damaged specimen of a Tse-tse fly purporting 

 to come from the lower Kukema River, a couple of hundred 

 miles to the east of the place where I found the subspecies 

 under discussion, and a native report to the effect that a "fly 

 belt" is known to exist on the upper Coanza still further inland. 

 In view of Mr. Austen's belief that Gl. palpalis wellmani 

 extends to the Cunene River I have visited the upper Cunene 

 but failed to find any Tse-tse flies, and now, in accordance with 

 his suggestion, written me when the flies were first discovered, 

 I hope to, before long, visit the lower river with this object 

 in view.J At least one species of Tse-tse is common in north- 

 ern Angola and along the lower Coanza. This may very pos- 

 sibly be wellmani. The distribution of the species palpalis 

 (with its subspecies and varieties) is now known to extend 

 practically from Cape Verde to Damara Land.§

t Mr. Ralstone, of the Benguella Railroad, has recently informed me 

 that a Tse-tse fly is found lower down on the Cunene River. This is 

 very probably Gl. palpalis wellmani.
