length of antennal segment i is equal to width of vertex plus one- 

 half dorsal width of an eye. 



Male: Length 9.4 mm., width 3.5 mm. Head : Width 1.56 mm., 

 vertex .86 mm. ; red, tylus, front, and vertex, chiefly black ; pubes- 

 cent, finely granulate. Rostrum, length 2.85 mm., reaching to 

 middle of hind coxae, black. 



Antennae: Segment i, length 1.06 mm., clothed with moderately 

 heavy and slightly reclining hairs which in length about equal 

 thickness of segment; ii, 3.23 mm., thickest near base and tapering 

 to more slender at apex, clothed with short stiff black hairs and 

 fine pubescence, length of longest hairs not exceeding thickness of 

 segment; iii, 1.71mm.; iv, 1.28mm. 



Pronotum: Length 1.74 mm., width at base 2.92 mm., collar 

 1. 3 1 mm. ; surface very slightly shining, thickly clothed with short 

 pale pubescence ; basal margin of calli distinctly impressed ; red, 

 dorsal area of collar, calli except outer angles, and a broad band 

 extending to basal margin of disk, black. Scutellum black; 

 sternum blackish, median line red ; pleura red, or becoming dusky. 



Hemelytra: Embolar margins only sHghtly arcuate; black, 

 opaque, surface somewhat scabriculous, clothed with short dusky 

 pubescence, hairs somewhat decumbent on apical half. 



Legs : Black ; tibiae thickly clothed with prominent erect hairs, 

 length of several exceeding thickness of segment, spines not 

 evident. 



Venter : Red, genital segment becoming black ; clothed with 

 prominent pale pubescence; genital segment with a large and 

 prominent, erect tubercle just above base of left genital clasper, 

 also another but smaller tubercle directed distad from near base of 

 right clasper. In confraternus the right tubercle is scarcely raised 

 from the segment wall.

 form and color. Head: Width 1.56mm., vertex .87mm. Width 

 of collar 1.30mm. Antennae: Segment i, length 1.02mm.; ii, 

 2 mm., clothed with pubescence as in the male but beset with 

 several exserted hairs which in length exceed thickness of segment; 

 iii, 1.71mm.; iv, 1.24 mm.
