FLIES OF GENUS CONOPS — CAMRAS 167 



Physoconops (IPachyconops) gracilior (Krober) 



Conops gracilior Krober, Arch. Naturg., vol. 81, Abt. a. Heft 5, p. 150, 1915. 



Range: Brazil (Santa Catarina), Paraguay. 



Material examined: Paraguay: Krober collection, 1 male, 1 

 female (co types, USNM). 



Physoconops (Pachyconops) criidus (Walker) 



Conops cruda Walker, List of the specimens of dipterous insects in the collection 

 of the British Museum, vol. 3, p. 671, 1849. 



This species has not been identified since originally described. 

 Judging from Krober's redescription it belongs to this subgenus and 

 is related to guianicus. The origin of the type is not known, but Krober 

 felt that it is a Neotropical species. 



Physoconops (fachyconops) guianicus (Curran) 



Conops guianica Curran, Bull. Amer. Mus. Nat. Hist., vol. 66, p. 417, 1934. 



Range: British Guiana, Venezuela, Colombia, Brazil, Peril. 



Material examined: British Guiana: Kartabo, June 30, 1924, 

 1 female (type, AMNH). Venezuela: Las Adjuntas, 959 m., July 4, 

 1926, H. E. Box, 1 female (USNM). Colombia: Don Diego, Mag- 

 dalena, 100 ft., May, H. H. Smith, 1 female (author's collection, ex 

 Carnegie Mus.). Brazil: Campinas, Goyaz; collectors, Borgmeier, 

 Lopes, and Spitz, 2 males, 1 female (USNM); Maracaju, Mato Grosso, 

 May, 1937, R. C. Shannon, 2 males, 1 female (USNM). Peru: 

 Pucallpa, May 21, 1951, J. M. Schunke, 1 female (author's collection). 



Physoconops (jPachyconops) grandis (Williston) 



Conops grandis Williston, Kansas Univ. Quart., vol. 1, p. 44, 1892. 



Range: Brazil (Mato Grosso). 



Material examined: Brazil: Chapada, 1 male (cotype, Williston 

 collection, AMNH); 1 female (probably a cotype, Wilhston collection, 

 AMNH) ; Chapada, 1 male (probably a cotype, in USNM but with 

 AMNH label). 



Physoconops (Pachyconops) rufus (Williston) 



Conops rufus Williston, Kansas Univ. Quart., vol. 1, p. 44, 1892. 



This species resembles ^ow)^se?^(/^ (=auratiLs), but the pollen behind 

 the vertex is relatively indistinct. Krober's records of gracilis, from 

 Chile in 1915, apparently belong to this species. He also correctly 

 identified this species from Brazil at that time, but in his last work 

 (1939) he incorrectly used this name for a species of Physocephala. 



Range: Brazil, Chile. 



Material examined: Brazil: Chapada, January, 1 male, 1 female 

 (cotypes, AMNH); Maracaju, May 1937, R. C. Shannon, 2 females
