times as long as wide in both male and female; body a little larger, 

 notably stouter; head still larger, though otherwise nearly as in 

 gilvipes, fully four-fifths as wide as the prothorax; last palpal joint 

 very much longer than the third and thicker, acutely pointed; 

 prothorax less transverse, a fourth or fifth wider than long, through- 

 out nearly as in gilvipes, except that the apical angles are less obtuse 

 and the base and apex more nearly equal; elytra two-fifths (c?') to 

 one-half ( 9 ) longer than wide, nearly one-half wider than the pro- 

 thorax, very obtusely rounded behind, the structure nearly as in 

 gilvipes, and, as in others of this group, very finely reflexed at the 

 sides; hind tarsi slender, as long as the tibiae. Length (d^ 9 ) 

 3.8-4.0 mm.; width 1.45 mm. New York and District of Columbia 

 to Illinois. Five specimens. [B. terminalis Lee.]... .notatus Hald. 



4 — Elytra uniform in coloration or virtually so 5 



Elytra pale, variegated with sharply defined black areas and spots. ..11 

 5 — ^Prothorax moderately transverse, strongly narrowed behind, the 

 base narrower than the apex; antennse clear and pure flavo-fer- 

 ruginous throughout. Form oblong, moderately convex, shining, 

 black, the lateral edges finely paler from diaphaneity; under surface 

 black, the epipleura obscure testaceous; legs very pale flavate; 

 head large, shorter than wide, four-fifths as wide as the prothorax, 

 convex, broadly concave and duller at the sides of the very broad 

 apex; fourth palpal joint much longer than the third, gradually 

 paler apically; eyes notably large, convex though only moderately 

 prominent; antennae almost three-fourths as long as the body, very 

 slender, filiform and not distinctly compressed as they are in the 

 preceding group, the medial joints four times as long as wide; 

 prothorax a third wider than long, widest and laterally rounded at 

 apical third, the sides thence oblique and straight posteriorly, the 

 angles very obtuse, with slightly blunt tips, the apical angles rather 

 sharply defined and subprominent; apex broad, rather deeply and 

 evenly sinuate, much wider than the base, which is transverse 

 medially and obliquely arcuate laterad; surface feebly convex, the 

 transverse impressions shallow but evident; stria finely impressed 

 between them; fovese elongate, narrow, deeply impressed in basal 

 third; sides finely reflexed, more broadly at base; elytra parallel, 

 rapidly very obtuse at apex, three-fifths longer than wide, about 

 one-half wider than the prothorax, the sides very finely reflexed, 

 rapidly rounding at base; surface with feeble iridescent lustre; 

 striae fine, impressed, smooth, the intervals very slightly convex, 

 the two punctures along the outside of the second stria very fine; 

 hind tarsi much shorter than the tibiae. Length (9) 5-6 mm.; 

 width 2.0 mm. Iowa (Cedar Rapids), — Brendel.. .flavicornis n. sp. 

 Prothorax strongly transverse, very moderately narrowed behind, the 



base as wide as the apex; antennae always dark in color 6 



6 — Head very large, distinctly wider than an elytron 7 



Head smaller, always narrower than an elytron 9 



7 — Sides of the prothorax feebly reflexed. Body rather larger in size, 

 feebly convex and shining, obscure testaceous, the prothorax and 

 elytral suture paler, the head black; elytra barely visibly iridescent;
