﻿AUSTENI, G. FUSCIPLEURIS AND G. LONGIPENNIS. 



357 



fine erect hairs ; proximal lobe-like extensions divergent and broadly rounded. 

 Juxta (j) relatively much narrower distally than in G. longipalpis, and of a 

 similar form to that of G. morsitans. Hectors with the black spines narrowly 

 but clearly divided medially. 



The first and only example, a female, was submitted to me for identifica- 

 tion by Mr. R. P. Filleul, Assistant District Commissioner at Alexandra, 

 Grorha, Jubaland, British East Africa ; under date March 17th, 1912. This 

 specimen formed the type of the original diagnosis given by me in the Annals 

 of the Liverpool School of Tropical Medicine (Z.c). Recently Mr. Filleul has

very kindly forwarded a series of 22 specimens of this tsetse-fly of which 

 8 are males and 14 are females, all in an excellent state of preservation. He 

 also furnished me with the following particulars regarding his captures : 



" I am glad this small fellow you call austeni is of interest to you. I have 

 just been on ' safari ' to the northern part of my District and send you my 

 catch. I found them in the same localities with G. pallidipea and G. brevipalpis, 

 the proportions being pallidipes 150, austeni 20, brevipalpis 5. I regret I do 

 not know the classical names of the trees, but perhaps the following will 

 assist. Jubaland is apparently all alluvial soil, chiefly the extremely fertile 

 black cotton soil, but owing to lack of rain-fall and irrigation it is only 

 cultivated by the Wagosha in primitive fashion along the river banks, where 

 the forest has been felled. There are occasional swamps or deshehs, as they 

 are called in Somali, which are filled up by the floods in November or 

 October and are dry for the most part by the following June. The river 

 banks and the edges of the deshehs are covered with forest. Amongst the trees 

 are Dane Palms, Sycamore Figs, Candelabra trees [Euphorbias], &c. The 

 specimens enclosed were all caught within § mile of water.
