 the period inckided between these two dates.

It will be noticed that the disproportion of the sexes 

 was very marked indeed; sixty-two females to one male. 



I may mention that when I found it necessary to finish 

 up the work in mid-September, I dissected the remaining 

 unhatched pupae to ascertain whether they were, or were 

 not, playing the part of hosts. In no pupa was I able to 

 determine a parasite, Mutilla or otherwise ; several of the 

 pupae had obviously " dried-up," while with others the 

 incipient imago had suffered casual injury. 



Unfortunately I found it necessary to return to my 

 station at Mwengwa during September, to be in readiness 

 to trek to Kashitu. Hence the work was left incomplete, 

 and here, as yet, the breeding-season of tsetse has evidently 

 not thoroughly commenced.
