The genus Pronceus very closely approaches to Chlorion, in 

 fact contains its African representatives, which only differ from 

 the Indian group in having the labial and maxillary palpi longer ; 

 the number of joints are the same, and the neuration of the wings 

 identical ; the antennae of the males are grooved longitudinally, 

 as in the genera Chlorion and Sphex.
