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 Clitopa 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 inelined 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 Per- 
clitopa, Brensk. I am afraid, however, that this point can never be 
elucidated.
