﻿On tlie Bomhiiliiil Fauna of Snvfh Africa (Dipfera). lo7 



This sj^ecies is widely spread over all the Ethiopian region, and will 

 be described by nie in a paper on the Bombyliidae of the British 

 Museum. Nothwithstauding the 3 submargiual cells it cannot be 

 placed in Exojyrosojm owing to the different shape of tlie third antennal 

 joint ; in general pattern and colouring it is similar to the species of 

 the/ewes^rai«s-group, to which it belongs undoubtedly. I suspect that 

 the A7ithra,v cojf'er of Wiedemann, placed in Exopro>topa by the authors, 

 may be the same as the present species.
