Bionomics. 



In view of the possibility that G. hrevipalpls may ere long be 

 proved to be a carrier of human trypanosomiasis, and the fact 

 that in the German East African littoral, at any rate, it is 

 stated to be the chief disseminator of Tsetse-fly disease among 

 domestic animals,* special importance attaches to a knowledge 

 of the bionomics of the present species. Although many 

 important details have doubtless still to be i*ecorded, thanks 

 to the observations and writings of Drs. Franz Stuhlmann, 

 J. B. Davey, and Meredith Sanderson, f more is already known 

 concerning the habits of G. brevijjalpin than about those of any 

 other Tsetse, with the exception of G. palpalis and niorsitana:. 

 Stuhlmann (who, like the other authors, of course writes of the 

 species as Glossina ^\fusra"), besides furnishing a detailed 

 description of the anatomy and histology of the internal organs, J 

 has also provided us with an interesting account of G. hrevipaJpis 

 as observed by him in German East Africa, both under natural 

 conditions and in captivity, and the following reminte is based 

 upon his statements and those of the English writers men- 

 tioned above, whose observations were made in the Nyasaland 

 Protectorate.
