" A little time ago, some Griquas having with them 

 eight waggons, attempted to cross the country in which 

 this insect lives to the north-west of the Transvaal 

 Republic. They lost all their animals, and were obliged 

 to abandon their waggons and return on foot " (p. 984). 



" This fly seems to live only in localities in which 

 game abounds. ... It appears neither to increase nor to 

 diminish in number, according to the statements of traders, 

 though, as in all parts of South Africa, the- natives are in 

 the habit of setting fire to the pasture every year. . . . 

 The Tsetse most usually attacks the region between the 

 tliighs and the belly of animals. ..." (p. 985). 



" The Tsetse has no uncertain flight, like most of the 

 other Diptera ; quick as an aiTow, it darts from the top 

 of a bush to the point that it wishes to attack ; it seems 

 also to possess very keen sight. Mr. Chapman, one of the 

 travellers who has penetrated farthest into the interior of 

 South Africa, narrates that while out shooting, having an 

 almost imperceptible hole in his clothing, made by a thorn, 

 he often saw the Tsetse, which appeared to know that it 

 could not penetrate the cloth that he was wearing, make 

 a dart and succeed, without ever missing its aim, in biting 

 him in the small space that was not protected. 



"The Bushmen assert that this fly is viviparous, and 

 Mr. Edwards, the companion of Mr. Chapman, and a, 

 highly intelligent man, having one day expressed to them 

 his disbelief as to this, they brought him a pregnant 

 female, and having in his presence opened it along the 

 middle Txne of the abdomen, he states that he saw three 

 little flies ready to take flight emerge from it " [! !] (p 986).
