The occurrence of G. paUkliprs in the Mozambique district of 

 Portuguese East Africa is recorded by Professor La varan, who 

 states, on the authority of M. G. Vasse, that in the region in 

 question G. ])allidipe,s is found at higher altitudes than G. 

 morsitans* In the East Africa Protectorate, however, whei'e it 

 is said to be more widely distributed than any of its congeners, 

 G. pallidipes has not been observed at an altitude of more than 

 5,000 feet.f In the Uganda Protectorate, Dr. R. van Someren, 

 writing from Fort Portal on January 10th, 1911, states that the 

 present species occurs, in company with G. morsiians, Westw., in 

 several localities in Toro. 



Bionomics. 



The late Dr. AV. A. Deusham, writing from Nimule on July 

 24th, 1906, with reference to Glossina pallklipes as observed and 

 collected by him in the Nile Province, Uganda Protectorate, 

 said : " Of thirteen specimens taken, nine were males and four 

 females. The flies were found near and in a narrow belt of true 

 forest at Kibero, between Nimule and Wadelai, in June, 1906. 

 They were numerous along the native path, in long grass with 

 scattered trees, for a quarter of a mile before reaching the forest. 

 They attacked freely at 8.30 on a sunny morning, were easily 

 caught with the hand, and were observed to bite through a worn 

 blue service puttee. They were seen and caught along the native 

 path after entering the foi'est, and for two miles the other side' 

 of the belt, which is only about 300 yards in width, occasional 

 flies were seen until the village was reached. Half-an-hour after 

 arrival two were captured by my boys in camp and brought to 

 me. On returning from the village next day no flies were seen 

 until nearing the forest, so that the ' occasional ' flies mentioned 

 above may all have been ' following ' flies. If so, they follow 

 much further than G. paJpalis. There are many rhino, pig, and 

 buffalo in the forest, and Colobus monkeys are numerous. There 

 are no natives nearer than two miles, but a well-trodden path 

 connects two villages, and passes through the Fly. The natives

 Sciences, t. cxliv, p. 551 (1907). That G. pallidipes also occurs in the 

 littoral region of Portuguese East Africa is proved by the recent discovery 

 of the species near Quelimane, by Dr. J. F. Sant' Anna {vide supra).
