12() NOIM'II AMKHICAN NVSSONIDAE (HYMENOPTERa) 



prominent, with deep, well separated punctures, and a sharply differentiated 

 epirnemial area, separated below and on the sternum by a carina. Pro- 

 podeum irregularly sculptured, the upper surface with several small basal 

 areas, the middle two of which arc larger than the others and prominent 



posteriorly. 



Dorsal surface of abdomen evenly covered with moderately coarse, not 

 dense, punctures, these be(H)ming closer toward the apex; second ventral 

 segment strongly convex at base, but by no means truncate. 



Habitat.— CxEorgia: Bainbritlge, Decatur County, July 15 to 

 27, 1909, three males, (the author). 



Tijpes. —lloloiype, &, Cornell Univ. no. 136.1; paratypes, 

 two males, nos. 136.2, 136.3. 



A male from Albany, Georgia (Georgia State Accessions, no. 

 1300) has the scutcUum punctured posteriorly, weakly canalicu- 

 late in front. 



This species is nearest mellipcs and subineUipes. From ]:>oth 

 it differs by the absence of two prominent ridges between the 

 ocelli, by having the last segment of the antennae more deeply 

 excised behind, as well as by the canaliculate scutellum. 



Nysson (Brachystegus) opulentus sut)spccics basilaris Cresson 



cf. The first abdominal segment black at base and medially; the hind 



tibiae and tarsi black. The scutellum is coarsely punctured except at base 



which is smooth. 

 Georgia: St. riimou Island, April 22 to May 12, 1911, one male, (the 



author). 



Allotype. — Cornell University no. 137.1. 



A close examination of the type of bam.laris Cresson shows 

 that the scutellum is really confluently punctured on Ihe apical 

 two-thirds, the walls of the punctures giving somewhat the ap- 

 pearance of longitudinal folds, as mentioned in Fox's key. I 

 believe that this is really a southern form of opulentus, as it differs 

 in no essential respect from a New York specimen assigned to 

 that species by I'\)x.
