Dicranomyia venustipennis is a strikingly beautiful fly that 
may well be considered as representing a distinct group of 
species or even a subgenus. ‘The structure of the anteune, 
especially the arrangement of the verticils and the shape 
of the ultimate segment, and the venation, especially the 
exceedingly elongate sector and the very short Cw, all 
indicate an isolated fly, whose nearest relatives as known are 
presumably species such as D. recurvans, Alex., D. recedens, 
Alex., and other members of this group. 
Rhipidia pallidipes, sp. n. 
Generally similar to R. miosema (Speiser); general
