 facial angle scarcely equal to a right angle, front hroadly convex, carina obso- 

 lete, vertex separated by a groove from the black and broadly exposed collum ; 

 pale testaceous, front rather broadlj^ base of tylus, above base of antenna and 

 extending along front margin of eye where it terminates in a spot on vertex, 

 geminate mark on tylus which may be fused in darkest specimens, spot on 

 genae, dorsal margins of bucculae and lorae, more or less on juga and tip of 

 tylus, blackish. Rostrum, length 2.62 mm., nearly attaining posterior margins 

 of the hind coxae, dark brownish to piceous. 



Antennae: segment I, length .43 mm.; II, 1.51 mm., gradually thickened 

 from base toward apex, almost equaling the thickness of segment I, pale 

 pubescent, length of exserted hairs just equaling thickness of segment; III, 

 .54 mm. ; IV, .47 mm. ; fusco-brownish to blackish. 



Pronotum: length 1.45 mm., wndth at base 2.31 mm., anterior angles 1.14 

 mm., collar .81 mm. ; moderately convex, coarsely and rather closely punctate, 

 lateral margins slenderly carinate, anterior angles slightly rounded but dis- 

 tinct ; calli convex, confluent, black and shining, delimited behind by coarse 

 punctures, a black arc extending forward from the antero-lateral angles to 

 front margin of disk ; punctures black, posterior lobes of disk largely fusco- 

 brownish, paler near lateral margins and at anterior angles ; propleura more 

 finely punctate, brownish black, paler around the margins ; xyphus slightly 

 convex anteriorly, depressed posteriori}', testaceous to fuscous. Scntellum 

 moderately convex, smooth and shining, brownish black, basal angles, apex, 

 and median line pale or ivory-white. Sternum and pleura brownish black, 

 opaque, a spot at dorsal margin of meso- and one on meta-episterna shining; 

 ostiolar peritreme white, becoming infuscated dorsally. 



Hemelytra: width 2.74 mm., embolar margin slightb' sinuate, moderately 

 convex, closely and rather coarsely black punctate ; fusco-brownish to piceous, 

 embolium paler between the punctures, apical half of corium piceous, becoming 

 more nearly black at middle, extreme apical margin of corium more or less 

 translucent. Cunens fusco-brownish. more translucent on basal half and black- 

 ish at apex, punctures black. Membrane pale, fusco-brownish on the apical 

 half and produced basally at middle, veins dark fusco-brownish, the areoles dark- 

 ened apically, a blackish mark lying against the brachium just outside at apex 

 of the larger areole. 



Legs: fusco-brownish, basal half of femora paler but with dark points, 

 hind femora darker on apical half but broken by an obscure and interrupted 



pale band before apex ; tibiae dark 

 fusco-brownish, frequently paler 

 at middle of the apical half, some- 

 times with a pale mark just be- 

 low the knee but never distinctly 

 triannulate; tarsi dark brownish 

 to blackish, claws brownish trans- 

 Uiccnt ; arolia slender, bristle-like, 

 translucent, erect and protruding 

 . , forward in front of the claws,
