In the rudimentary nasus, the extreme shortness of Rs, 

 and the long fusion of Cui with M3, as well as in the small 

 size ot" the cell 1st Mc,, this species is very distinct. 2\ in- 

 conspicua, de Meij., is similar in many respects, but in 

 that species the contact of Cui with M3 is almost puncti- 

 form. lu the rudimentary nasus and the shortness of the 

 vcrticillate hairs on the under side of the flagellum the new 

 species resembles the European T. varilcornis, Schum.
