CEROFALES, Latr. 



Of this very distinct genus we have only two British 

 species, both of which are black with yellow or red mark- 

 ings, and both may be at once known from any other 

 genus of the Pompilidse by the antennce being inserted 

 high up above the base of the clypeus ; wings with the 

 cubital nervure extending to the apical margin ; the ? may 

 also be known by the long exserted sheaths of the sting, 

 and by the antennte, which after death do not tend to curl 

 up spirally ; S with the penicilli very wide and foliaceous, 

 not constricted at the base and not palpiform, the tibial 

 spines iii both sexes are so short as to be hardly observable. 

 Kohl in 1884 quotes forty-two species of this genus, nine 

 being Paleearctic.
