The generic position of this species is doubtful, but it is 

 nearer to Eucyrtothynnus than to Elaphroptera. It is allied 

 to E. mapirensis, Turn.

Mons. Brethes (An. Mus. Nac. Buenos Aires^ xx. p. 229, 

 1910) sinks this species and 2\ cordoviensis , Weyenb., "with 

 some doubt as synonyms of T. rufipes, Guer. AYeyenberj^h 

 evidently used the generic name Tachypterus because the 

 mandibles are tridentate and both recurrent nervures 

 received by the second cubital cell, whereas Guerin plainly 

 states that in T. rujipes the second recurrent nervure is 

 received by the third cubital cell. The name Tachypterus is 

 correct, and Mons. Brethes has been misled by a mistake in 

 Dalla Torre's catalogue in correcting it to Trachypterus, 

 uhich is quite a different genus, not belonging to the 

 Thynnida). Whether his identification of Guorin's species 

 is correct or not I cannot sny, as he gives no description of 

 the male. He docs not mention the neuration in any of 

 bis descriptions of Thynnidui or Scoliida\
