sides, except tip ; apical cell closed in the margin or very short- 

 petiolate; male e3^es not contiguous, well separated, the parafron- 

 talia broad, the frontalia reduced to a line; male hypopygium 

 not large, of moderate size; weak marginal macrochaetae on anal 

 segment, and bristle rows on margins of second and third segments. 

 This genus appears to be confined to East Africa.

Facial carina broadly developed, widely separating the an- 

 tennae; epistoma Rhinia-Wko. ; arista ciliate on upper side only ; 

 apical cell short-petiolate, the petiole about half as long as small 

 crossvein and in line with final course of fourth vein ; male eyes 

 nearly contiguous, the frontalia completely pinched out; male 

 hypopygium small; weak bristle-like macrochaetae on margin of 

 anal segment; female vertex about one-fifth of head-width. 



Idielliopsis similis, sp. nov. 



Length of body, g to 9-5 mm. ; of wing, 65 to 7 mm. Three 

 males : Dhikala, Naini Tal District, United Provinces of Agra and
