 ANAPORIA, new genus. 



Genotype. — Aporialimacodis Townsend, 1892.^ 



Differs from Paraporia mainly in the clypeus being distinctly, 

 though slightly sunken, the arista thickly short-pubescent halfway, 

 the male abdomen conico-subcylindrical and truncate anally. The 

 clypeus is quite flush in Paraporia, while the male abdomen is flattened 

 and pointed anally. The ocellars are quite strong, at least in male, 

 and there are two weak discal scutellar pairs. There are no well- 

 developed median anterior macrochaetae on second segment.

Length, 13 mm. One male, Huadquina, Peru, 5,000 feet, July 30,

 All four of the abdominal segments with whitish lateral spots which 

 are small and restricted. Wings conspicuously yellow across basal 

 third; brown on outer two-thirds of costal portion. The grayish 

 pollen has a yellowish or brassy tinge.
