Santarera, One 9, two d specimens. The clypeus is much 

 longer and narrower than in E. sericea Sauss., and the black mark- 

 ings of vertex and reddish flagellum are good superficial charac- 

 teristics. 

 Eumenes laevis Sauss. 



Corumbu, Pedra Branca and Mararii, April; Santarem. Nine 

 specimens. 



Eumemes novarae Sauss. 



Chapada, December; Santarem. Six specimens. Strongly 

 resembles E. Icevis, from w^hich it may be readily separated by 

 distinctly punctured abdomen and want of maculation on middle 



segment. 



Eumenes insignis n. sp. 



?. — Deep black, covered with sericeous gray pile especially on 

 abdomen; spot behind base of antenna?, in the emargination of and 

 behind summit of eyes, narrow interrupted line on pronotum both

 ing segments entirely black, the petiole beneath reddish; flagellum 

 at base beneath, tibise and tarsi, more or less marked with black- 

 ish, reddish; front with distinct, though not coarse separated 

 punctures, medially impressed ; ocelli in a ciu'ved line; clypeus

 on middle segment where the punctures are strongest; pronotum 

 margined anteriorly; dorsulum with a slender smooth line anteri- 

 orly in middle; scutellum with a short feeble longitudinal carina at

 but transversely depressed before apex, with widely separated 

 punctures above; remainder of abdomen rather fusiform but
