 apically, inner margin of mandibles, scape beneath, line on pronotum

 spots on first segment of abdomen, its posterior margin, and posterior 

 margin of segments 2 and 3, or 2-4, narrowly, yellow ; wings light 

 fuso-hyaline, costal cell somewhat yellowish ; femora sometimes

9 . — Clypeus about as broad as long, obtusely angular anteriorly, 

 rather distinctly punctured ; space between hind ocelli equal to 

 nearly two -thirds of that between them and eyes, the space between 

 the latter and base of mandibles not equal to the width of the latter ; 

 pronotum margined ; dorsulum more than one-quarter longer than 

 broad. Length 14 mm. 



Var. — Clypeus entirely black ; femora striped with yellow ; lateral 

 spot of first segment coalescing with the yellow at apex. Length 

 13 mm. 



Chapada, March. Two specimens. Resembles P. cinerascens, but 

 differs in color of wings. In the bi-spotted first segment it seems to 

 have some resemblance to P. biguttahis, but that species is quite 

 differently colored, judging from the description. 



Polybia fulvofasciata DeG. 



Chapada, January, April, September to December. Forty-three 

 specimens. 



Polybia fasciata Lep. 



Chapada, February, March, June, September, October. About 

 one hundred specimens. 



Leipomeles lamellaria Mobius is colored precisely as P. fasciata 

 judging from the description. Are they perhaps identical? P. 

 fasciata is a Polybia, however. 



Polybia fastidiosuscula Sauss. 



Over 100 specimens. Chapada, April, September to November. 



Polybia surinamensis Sauss. 



Rio de Janeiro (July, November); Mararu (April); Santarem. 

 Sixteen specimens.
