base, black, finely pale pubescent: III, .43 mm.; IV, .43 mm.; last two segments 

 slender, black, pale pubescent. 



Proiiofuin: length 1.11 mm., width at base 1.82 mm., anterior angles .83 

 mm. ; collar .68 mm., pale, opaque ; disk moderatelj^ convex, glabrous, shining, 

 rather coarsely punctate and especially so just behind the calli ; lateral mar- 

 gins nearly straight, slenderly carinate, anterior angles narrowed, little wider 

 than the collar; calli moderately convex, smooth and shining, confluent, de- 

 limited behind by an impression and also by coarse punctures ; calli black but 

 pale just before, median line but more broadly just behind calli, a rather broad 

 ray behind lateral angle of each callus, and slender basal margin of disk, pale; 

 propleura punctate, blackish, more or less pale around the margins ; xyphus 

 convex, blackish, the carinate lateral margins and in front on collar pale. 

 Scutcl!n))i punctate, moderately convex, basal angles, apex, and usually the 

 median line pale or ivory-white ; mesoscutum black, distinctly exposed. Sternum 

 black, opaque, only a spot at the dorsal margin of the episterna shining; ostiolar 

 peritreme white, posterior and ventral margins of the epimera pale. 



Hemclytra: width 2.14 mm., costal margin nearly straight or only very 

 slightly arcuate; corium and clavus slightly more convex than in atrivcntris, 

 coarsely punctate, more closely near the claval suture, glabrous, shining ; pal- 

 lido-testaceous, rather broadly across apex of corium and embolium, narrowly 

 at base, a transverse blotch at middle of corium which continues along claval 

 suture and across apex of clavus, piceous ; punctures, slender edge of embolium 

 and inner margins of clavus blackish. Ciincus pale, usually the apical half and 

 the punctures blackish. Membrane pale fuliginous, apical half, the brachium 

 and somewhat invading the membrane, infuscated, a clear spot bordering apex 

 of cuneus. 



Legs : apices of coxae and bases of trochanters pale, femora reddish brown 

 or blackish, biannulate with pale at apices, front pair more distinctly so ; hind 

 femora usually more or less pale at middle on the anterior face; tibiae biannu- 

 late with pale, the hind pair with a third pale indication just below the knee, 

 a row of spines on the anterior face ; tarsi blackish, claw's slender, not toothed 

 at base, fusco-translucent ; arolia simulating fine bristles, translucent, inclined 

 forward betw^een the claw^s, nearly parallel but converging slightly at tips.
