BASED ON A STUDY OF THE MALE GENITAL ARMATURE, 27 
In a more recent communication Dr. Shircore states :—‘* I think it must be 
different from G. palpalis. I have seen so many specimens of G. palpalis and 
this fly side by side ; and especially round Nimule, they are constantly found in 
certain places with the larger G. palpalis. The difference in size in fresh speci- 
mens is very noticeable. The G. tachinoides* is found chiefly along the course

of very rocky streams, whereas the large one occurs along streams of quite a 
different character. Dr. Wiggins to whom I showed the fly inclines to my view 
that it is certainly different from the ordinary G. palpalis; as also does 
Dr. Mackie, of the Sleeping Sickness Commission, who was out here with 
Sir David Bruce.” 
Glossina pallicera, Bigot. 
Genital armature of the male (fig. 13). Superior claspers (sc) united by a 
membrane ; base of clasper four times broader at the base than at the distal 
extremity, with the inner basal portion extended inwardly so that it comes very 
near to the juxta; outer basal portion broadly rounded and with a broad curved 
and somewhat attenuated process, the tip of which rests upon the inner basal 
process ; this portion of the clasper is clothed with fine pubescent hairs ; margins 
gradually tapering distally ; apex suddenly truncate, the inner half bearing a 
few short spines; bristles on the inaer lateral margin gradually shortening 
distally, those on the outer lateral margin few in number, some of which are 
* Dr. Shircore apparently has an idea that the species in question is Gr. tachinoides.—R.N
