search we found several more, and there can be no doubt whatever 

 as to the relationship of the two forms. So far as I could ascertain, 

 the female does not come out of her burrow at all, but merely sits in 

 it with the end of her abdomen exposed ; the passing males soon 

 collect round her, there being usually from six to twelve, and they 

 buzz about and tumble over one another in a most aimless manner. 

 After a few moments the female begins to descend into the earth, 

 and the males dig frantically in order to follow her. By this time 

 most of them will have flown, and only three or four which have got 

 the best start continue digging. I do not know to what depth they 

 finally go, though in one case I found a female about four inches 

 down with two males still following her. The flight of males only 

 lasted three days. In the case of Glitopa rufiventris the flight was 

 evidently just over, for we only found the males resting on the 

 herbage." 



I have taken Clitopa bohemani, Blanch., as the type of the genus, 

 but I am not at all sure that it was founded on that species by 

 Erichson. If, as I am inclined to believe, it was on the species 

 from Mozambique described eight years afterwards by Klug under 

 the name of C. erichsoni, the genus would be identical with Peri- 

 clitopa, Brensk. I am afraid, however, that this point can never be 

 elucidated. 



Key to the Species. 

 A 2 . Clypeus separated from the frontal part by a suture. 



B 2 . Clypeus and frontal part clothed with erect, stiff, bristle-like
