not reach posterior coxae, will separate this species from all of those 

 with five marginal pegs on the jugum. 



Description. — Color: Dorsally and ventrally, except for legs and 

 labium, almost unicoloroiis reddish brown to piceous.

 0.57(0.50-0.70); interocular width, 0.36(0.31-0.44); clypeus as long 

 as juga, latter with five subequal, marginal pegs; surface, except 

 clypeus and apex of jugum, coarsely punctate. Antennal segments: 

 I, 0.12(0.10-0.17); II, 0.03(0.02-0.04); III, 0.28(0.23-0.36); IV, 

 0.28(0.23-0.33); V, 0.28(0.23-0.36). Labium attaining middle of 

 metasternum. Labial segments: I, 0.22(0.20-0.26); II, 0.30(0.27- 

 0.39); III, 0.39(0.31-0.53); IV, 0.26(0.23-0.31). 



Pronotum: Length about two-thu-ds width, 0.90(0.76-1.30): 1.44 

 (1.21-1.44); anterior margin shallowly concave, almost straight 

 across; lateral margin straight on basal half; transverse impression 

 obsolete, marked by vague row of punctures; anterior lobe with three to 

 four irregular rows of moderate to coarse punctures laterally, sub- 

 apically and along median band, calli mostly polished, with few fine 

 punctures discally; posterior lobe, except umbones, with widely scat- 

 tered punctures. 



Scutellum: Length-width ratio, 0.61 (0.50-0.81) :0.74(0.63-0.90). 



Hemelytron: Mesocorium with few scattered, obsolete punctures 

 discally; exocorium abundantly punctate across full width. 



Propleuron: Prosternal carinae lower than labial II, rounded. 



Legs: Anterior femur ventrally with premedian spine strong, 

 oblique, unevenly bifid, and with blackish, subapical tubercle on 

 postero ventral margin; anterior tibia neither angled nor spined mid- 

 ventrally; posterior femur not angled dorsally near apex, ventrally 

 with subapical spine short, less than half height of femur. 



Terminalia: Gonostylus as illustrated (fig. 294). 



Length of body: 2.56(2.08-3.26). 



Female: Similar to male, but without secondary sexual modifica- 

 tions. 



Head: Length-width ratio, 0.48(0.43-0.60) :0.60(0.53-0.73) ; inter- 

 ocular width, 0.36(0.31-0.46). Antennal segments: I, 0.12(0.10- 

 0.16); II, 0.03(0.02-0.04); III, 0.25(0.20-0.33); IV, 0.24(0.19-0.32);

 (0.23-0.26); III, 0.36(0.31-0.46); IV, 0.24(0.20-0.33). 



Pronotum: Length-width ratio, 0.92(0.80-1.16) : 1.53(1.31-1.92). 



Scutellum: Length-width ratio, 0.63(0.51-0.90) :0.77 (0.63-0.99). 



Length of body: 2.60(2.28-3.20). 



Type data.^ — Zimmer listed his lone type as a female, but illustrated 

 the typical leg armature of a male, from "South-east Nebraska."
