Discal cross-vein before the middle of the discal cell ; first 

 posterior cell often long and narrow. Often large flies. 



3 (4) Ambient vein absent, and the posterior long-veins hardly reaching 



the wingmargin. 



Face arched and produced but without any knob ; ocellar knob

 the male. POGONOSOMA. 



Two closely allied South European and two Asiatic species.
