pepsinae: tribe pepsini 49 



tellum, and often area on mesopleuron and propodeum, most of 

 coxae, and base of first abdominal segment, black; tegula rufous; 

 wings dark brown. 



The species nwperus belongs to a species group separate from the 

 Nearctic nebulosus, dakota, coloradensis, and apache, as evidenced by 

 the specialized male clypeus, flagellum, coxae, and subgenital plate 

 and in the female by possession of preapical bristles on the fifth tarsal 

 segment. The Nearctic nigricans belongs probably in the nuperus 

 species group but without its male this cannot be concluded with 

 certainty. 



Specimens (20 cf, 219): From District of Columbia; Georgia (At- 

 lanta); Kansas (Riley County); Maryland (Glen Echo and Takoma 

 Park) ; New Jersey (Gloucester County, Moorestown, and Riverton) ; 

 New York (Farmingdale) ; North Carolina (Hamrick); Pennsylvania 

 (Germantown, Ogontz School, and Philadelphia) ; Texas (Brownsville 

 and Lee County); and Virginia (Arlington, Black Pond in Fairfax 

 County, Dunn Loring, and Great FaUs). 



Dates of collection are mostly from July 2 to Sept. 5. Those 

 outside of this range are: Jan, 20 and Mar. 23 at Brownsville, Tex.; 

 Oct. 18 in Riley County, Kans.; and October in Lee County, Tex. 

 The usual habitat is along the edges of mesophytic deciduous woods 

 bordering on overgrown fields. There is one record of a female taken 

 at Liriodendron honeydew. 



This species occurs in the Carolinian and Austroriparian faunal 

 areas. Except in Texas and Kansas, adults have been taken only 

 from July to September, with a few stragglers into October.

Medium or large sized species of average stoutness, the Nearctic 

 species with forewing 9 to 26 mm. long; clypeus rather large, convex; 

 pronotum of moderate length, its hind margin arcuate; carina on 

 mesosternum in front of each middle coxa distinctly angulate medially, 

 at the angulation usually produced into a distinct tooth (In all other 

 Nearctic Pepsini this carina is evenly curved and without a toothlike 

 projection.); second intercubital vein straight, oblique; second re- 

 current vein joining the second cubital cell near its apical 0.75; cubital
