This genus was described by Szepligeti from an Ethiopian 

 species, E. iiit/ripenuis, Szep. 



The present species agrees well in structural details with 

 that insect, though the recurrent nervure is not interstitial 

 in niyrtpeiinis. lioth species show the curious jointed 

 terebra. Sui)crficially and in colour the present species 

 resembles Ijtfiituila.r ha/ijaetus, Cam.
