FLIES OF GENUS CONOPS — CAMRAS 169 



Mato Grosso, July 1939; 1 female (USNM), Campinas, Goyaz, 

 January 1936, R. Spitz. 



Remarks: This species has a relatively elongated abdominal tip 

 in the male, thus showing a tendency toward the subgenus Shannon- 

 oconops. Otherwise it is very similar to Physoconops magnus, which 

 also has the elongated sixth abdominal segment. However, it is 

 smaller than magnus; and differs from it, in the female, by having the 

 long theca and abdominal segments 2 and 3 nearly as wide as long. 

 In the female of magnus, the theca is relatively short and the abdomi- 

 nal segments 2 and 3 are elongated, segment 2 being about twice as 

 long as wide. Magnus also has three propleural bristles to the usually 

 one or sometimes two in travassosi. 



This name was selected by Shannon to honor the Brazilian entomol- 

 ogist Lauro P. Travassos.

Physoconops (jP achy conops) magnus (Williston) 



Conops magnus Williston, Kansas Univ. Quart., vol. 1, p. 43, 1892. 



This species is very similar to travassosi in the male, but the female 

 is very different, having a relatively short theca. The abdomen of 

 the female also has segments 2 and 3 elongated, so that segment 2 is 

 about twice as long as wide. The specimens seen have three pro- 

 pleural bristles. 



Range: Brazil (Mato Grosso). 



Material examined: Brazil: Chapada, 1 male, 1 female (cotypes, 

 AMNH)
