Genus Pezaptera, n. gen. 

 Costal and subcostals of primaries well defined ; subcostal with a 

 fork near apex, and a third branch (generally representing the 

 upper radial) emitted just beyond end of cell; lower radial 

 emitted with second and third median branches from lower ex- 

 tremity of cell ; an interradial and recurrent nervure, lying 

 close to the lower radial until near to the cell, which it passes 

 through to the base, thus making two discocellulars with the 

 usual angle. Secondaries small ; subcostal branches forming a 

 simple long fork ; upper radial and continuous recurrent ner- 

 vure running through the centre of cell and along the margin 

 of lower radial to outer margin ; discocellulars rather long, 

 nearly equal in length, the upper one slightly concave, run- 

 ning obliquely inwards, the lower convex, running obliquely 

 outwards, emitting the lower radial from its centre ; three 

 median branches, the second and third emitted near together 

 at end of cell. Body much as in Argyroeides, but the abdomen 

 rather less constricted. Type P. sordida.

The type of P. sordida is faded ; but P. divisa has its black 

 colouring ; in other respects the two types are identical.

I believe this to be a JEumenogaster ; it seems nearly allied to E. 

 notahiJis, so far as 1 can judge from the description.
