270 The Hunting JVasps 



6. Bemhex hidentata, V. L. Another ardent 

 huntress of Gad-flies. I have never seen her 

 pursue other game and I do not know on what 

 Fly the e^^ is laid. 



This great variety of provisions shows that 

 the Bembex have no exclusive tastes and fall 

 upon any species of Flies, indifferently, which 

 the hazards of the chase place within their reach. 

 They seem nevertheless to entertain a few pre- 

 ferences. Thus one species feeds more particu- 

 larly on Bee-flies, a second on Stomoxys-flies, a 

 third and a fourth on Gad-flies.
