 1.56 mm., gradually thickened from base to apex (.11 mm. thick) ; 

 iii, .84 mm., thickness .13 mm.; iv, .63 mm., thickness .13 mm.; 

 clothed with short, closely set pubescence, dark reddish brown to 

 blackish. 



Pronotum : Length .93 mm., width at base 1.66 mm. ; alutaceous,

 peritreme coarsely alutaceous, dark reddish brown. 



Hemelytra: Embolar margins slightly sinuate; dark brownish 

 black, cuneus frequently more reddish brown; clavus and basal 

 half of corium clothed with closely appressed scale-like hairs as on 

 scutellum, and sparsely interspersed with more erect, simple pubes- 

 cent hairs. Membrane and veins uniformly fuscous, slightly paler 

 bordering apex of cuneus. 



Legs : Dark reddish brown to blackish, anterior and middle pair
