species by the third submargiual cell being distinctly 

 wider than high, and the second more transverse ; the 

 clypeus in the $ is emarginately truncate, and the sides 

 of the face white. 



We hare only one British species. Kohl cites seven 

 Palfearctic species, out of a total of 118 otherwise dis- 

 tributed over the Oriental, Australian, Nearctic and 

 Neotropic regions.

 " I bred both sexes of this species from cells constructed 

 of mud, very similar to those formed by different species 

 of Pelopocus." 



AGENIA, SchiOdte. 

 Closely allied to Faemlogaiia, but distinguished from it 

 in both sexes by the united anterior and posterior basal 

 iicrvures of the forewings, and in the ? by the bearded 

 maxillie, and the two dark transverse bands of the fore- 

 wings ; these are represented also in the S, tut only very 

 faintly ; the posterior tibias in both sexes are simple, with 

 only fiue exaerted hairs.
