rather strongly arcuate from base to apex, a little less arcuate basally 

 than apically, the apical constriction wholly untraceable; basal lobe 

 abrupt; punctures rather coarse, deep, separated by their own diameters 

 medially, dense and coarser, with some series, laterally; smooth median 

 line not attaining base or apex; scutellum small, impressed; elytra two- 

 fifths longer than wide, barely at all wider than the prothorax and scarcely 

 three-fifths longer; sides parallel, the apex broadly arcuate, the humeri 

 prominent; grooves rather coarse, abrupt and deep, still coarser basally; 

 intervals much wider than the grooves, each with a single loose series of 

 small but distinct punctures, except the second and third intervals, 

 which are wider and with confused punctures; setae pale, very small; 

 abdomen with strong and rather close-set punctures. Length (9) 3-5 

 mm.; width 1.5 mm. Texas (Lavaca Co.). One example. 



This species is conspicuously different from those more closely 

 allied in the rounded form of the prothorax, evenly arcuate and 

 minutely punctured beak, and other characters as related above. 



Baris irrita n. sp. — Body subparallel, convex, not very stout or shining, 

 piceous-black, the prothorax somewhat rufescent; beak arcuate, finely 

 but distinctly, loosely punctate, scarcely more than half as long as the 

 prothorax in the male; prothorax scarcely a fourth wider than long, the 

 sides parallel and just visibly arcuate, rounding in about apical third to 

 the apex, the constriction obsolete; basal lobe rapidly formed, not 

 broadly rounded; punctures relatively coarse and separated by scarcely 

 their own diameters, dense and in some part lineate toward the sides; 

 median smooth line obsolete in the type; scutellum small, impressed 

 medially; elytra two-fifths longer than wide, just visibly wider than the 

 prothorax and three-fifths longer, the sides parallel, gradually rounding 

 in fully apical third, the humeri not distinctly prominent; grooves deep, 

 moderately coarse; intervals subequal in width throughout, each with a 

 single line of rather strong and somewhat close-set punctures, becoming 

 confused basally on some of the intervals; setee rather small; abdomen 

 with rather strong and not very close-set punctures, having at base a 

 very feeble impression in the male. Length (cf) 3.3 mm.; width 1.4 

 mm. Texas (Columbus). 



Differs very much from the preceding in the long and nearly 

 straight parallel sides of the prothorax, and, from retrusa, also in 

 the more parallel sides and in the much less coarse and conspicuous 

 single interstrial lines of punctures. 



Baris nephiana n. sp. — Somewhat narrowly oblong-elongate, convex, 

 somewhat shining, rufo-piceous in color; beak arcuate and not quite 

 three-fifths as long as the prothorax in the male, finely, not densely 

 punctate; prothorax nearly a third wider than long, the sides converging, 

 broadly rounding, then strongly converging, anteriorly, to the uncon- 

 stricted apex, at the middle of the length sometimes slightly sinuate; 

 basal lobe moderate, not abrupt; punctures moderate and separated by
