Pepsis chrysobapta Sm. 



Same locality as aurozonata. One male. 



Pepsis aurifex Sm. 



Chapada. One specimen. 



Pepsis speciosa Sm. 



Santarem. One specimen. 



Pepsis sumptuosa Sm. 



Chapada (November, December, March, April). Three females, 

 nine males. The Pepsis eximia Sm. (non R. Luc.) is, in my opinion, 

 the $ of this species, and I therefore propose the name confusa for 

 P. eximia R. Luc. (non Smith).. 



Pepsis citreicornis Mocs. 



One specimen. Santarem (February). 



Pepsis sp. 



Perhaps brunneicornis R. Luc, but differs somewhat, from the 

 description of the latter. One specimen, Corurnba (April). 



Pepsis pan Mocs. 



Chapada (October) ; Santarem. Two examples. 



Pepsis varipennis Pel.

 ber, November) ; Santarem (February).
