Pseudagenia femorata Sin. {=Agenia femorata Sm. non Fabr.). 



Santarem. Six specimens without date of capture. 

 Pseudagenia comparata Sm. 



Santarem (February and November). Ten specimens. 

 Agenia viridis Sm. 1 



One specimen. Santarem. 

 Agenia annulata Sm. 



Chapada (September). One specimen. 

 Agenia tarsata Sm. 



A specimen collected in April (no locality) is perhaps this species. 

 Agenia polistiformis Sm. 



Santarem. One specimen. 

 Agenia pallida Tasch. 



Chapada (November). The one specimen before me agrees fairly 

 well with Taschenberg's description, except that it is not unusually 

 pale, a character on which Taschenberg lays stress. 



Agenia femorata Fabr. 



Pompilus femoratus Fabricius, Syst. Piez., 190. 



Mararu (April) ; Santarem. Five specimens. 

 Agenia micans Fabr. 



Chapada (April). One specimen. Judging from the description, 

 Anoplius Richardi Lep. is identical with this species. 



Agenia chlorosoma Sm. 



Santarem. One specimen. 



Agenia curvinervis Cam. 



Same locality as chlorosoma. The only specimen in the collection 

 agrees with Cameron's description. 



Agenia producta n. sp. 



$ . — Head and thorax coppery-green ; abdomen, coxse, trochan- 

 ters and femora at base, black ; hind tibiae apically and tarsi more 

 or less fuscous ; antennas beneath, tegulee and legs except the parts 

 described above, reddish ; inner orbits narrowly yellow ; clypeus with 

 large punctures anteriorly, its fore margin angularly produced in 

 the middle ; pronotum gently arcuate posteriorly ; middle segment 



1 A I have pointed out elsewhere, the males of Agenia and Pseudagenia offer 

 no generic differences. Therefore, the new species described herein of which 

 only the male sex is known, are all referred to Agenia, notwithstanding the 

 probability of some belonging to Pseudagenia.
