Circumstances of capture: This fly was caught in the open and 
in the houses of Europeans. It feeds on all mammals, but seems to 
be especially fond of feeding at the tips of dogs’ ears Both on the 
Gambia and on the Congo dogs were often seen with their ears rav 
and bleeding from the attacks of this pest. 
*It is, I believe, over 60 years since Bouche discovered the larvae of 
Stomoxys calcitrans in warm stable manure. Since that time no 
additional information on the habits of this insect has apparently been 
givent; and the characteristics of the earlier stages and also the meta¬ 
morphoses have remained practically unknown. It was resolved 
therefore to : - 
i. i race out 
insect from the egg ; and 
*be natural habitat for the eggs, larvae and pupae,

n ing of the natural habitat lor the earlier stages of this insect prov 
no light task, and involved a considerable amount of time and diligl 
eaicimg. In the end, however, l succeeded in solvira
