Wings subliyaline, cells C and Sc brown, veins brown. Venation 

 (see Plate IX, figure 9) vein /?2 entirely obliterated and only two 

 branches of the sector attain the margin. 

 Abdomen broken. 



Holotype, Paraguay, Fiebrig, coll., in the Hungarian Na- 

 tional Museum. 



L. abnormis belongs to Psaronius Enderlein, if this be ad- 

 mitted as a valid genus or subgenus. 



We have here a venational phenomenon which is compar- 

 able to that in the subgenus Leiponeura of Gonomyia Meigen, 

 that is, the total obliteration of one of the branches of the 

 radial sector. This condition is presaged by L. obliterata 

 Alex.'s (British Guiana) but in this new species the loss 

 of R2 is complete. In keys to the Tipulid tribes this would 

 run down to the Antochini and students of the family should 

 exercise care in the study of this interesting group of species.
