NOTES ON THE GLOSSIN.^

with scrub near to the water. They are not found amongst the reed 

 beds or papyrus swamps such as exist in the Uganda river valleys. 

 They are never found away from water except where tiiey have followed 

 man or beast a mile or so for his blood. 



Habits. 



Their bites are as those of the G. morsitans. They flv rapidly, 

 settle quickly on the skin and soon ingest enough blood to fill them 

 out perhaps without a prick liaving been felt. 



Antenna of Glossina pallidipes, male.

Glossina palpalis and puparium. 

 (After Brumpt.) 



Feeding. 



When a G. palpalis has fed on an infected animal it becomes 

 infective on an average of 34 days from the feed. It remains infective 

 for about 75 days. 



Food. 



In populated districts man supplies sufficient blood but in captivity 

 or at any time they will feed on hot or cold blooded animals, birds or 

 reptiles. 



Reproduction. 



vSimilar to G. morsitans. 



Sandy banks banked by a belt of vegetation are often chosen. The 

 pup^e are found one to two inches below the surface of the ground 

 amongst or near to vegetation. 



There is no hereditary transmission of trypanosomes in the tissue, 

 all trypanosomes are obtained from the animals they feed upon.
