FLIES OF GENUS CONOPS — CAMRAS 179 



Eymelt correctly recognized that Krober had described two species 

 /under this name, but described the wrong one. A cotype in the 

 I American Museum of Natural History collection has been examined. 



Range: Texas (Brownsville), Mexico (Vera Cruz), Trinidad, BrazU, 

 Paraguay. 



Physoconops {Physoconops) inornatiis (WilHston) 



Conops inornatiis Williston, Kansas Univ. Quart., vol. 1, No. 1, p. 45, 1892. 



The two cotypes of inornatus have been examined and the name is 

 hereby restricted to the male, which was described first. The female 

 belongs to the new species infuscatus. 

 ■ Range: Brazil. 



Material examined: Brazil: Chapada, 1 male (cotype, AMNH); 

 Annapolis, Goyaz, Nov. 20, 1936, 1 female (USNM); Maracaju, 

 May 1937, Shannon, 3 males (USNM).
