Costa Lima (Mem. Inst. Oswaldo Cruz, 1930, pág. 255) has called 

 attention to the fact that hiteovenfralis (the type species of Dendromyia) 

 is in reality a member of the genus Wyeomyia. Dendromyia therefore 

 becomes a subgenus of Wyeomyia, while Prosopolepis Lutz, 1905, the 

 oldest ñame listed under Dendromyia Dyar (nec Theobald) automati- 

 cally assumes priority as the generic ñame of this group. P. typharum 

 is closely related to Dendromyia {Callad iomyia) melanoides, Root, (in 

 Dyar, 1928). This species has the white completely encircling the fith, 

 fourth and the tip of the third hind tarsal segments; presents only on 

 the ventral surface in our species. If this difference pro ves to be a mere 

 variation, then Root's species has priority.
