angles, which are minutely sharp and prominent; transverse impres- 

 sions distinct, the anterior not punctate; foveae large, two at each 

 side, punctate, the carinae short but strong; margins not widely but 

 abruptly reflexed; elytra a fourth longer than wide, barely at all 

 wider than the prothorax, obtusely rounded in apical two-fifths, the 

 coarse and deeply impressed striae strongly punctate, the intervals 

 very convex; scutellar stria wanting, represented by about two iso- 

 lated punctures. Length (9) 10.0 mm.; width 4.7 mm. Kansas 

 (Douglas Co.), Dyche gravidus n. sp. 



Body smaller, not so stout; scutellar stria generally evident though very 

 short 2 



2 Punctured area of the male prosternum broadly oval and feebly im- 

 pressed; body shorter, the elytra barely more than twice as long as 

 the prothorax. Lustre and coloration nearly as in the preceding; 

 head nearly similar, but with rather more prominent eyes, the slen- 

 der antennae pale ferruginous, extending to the thoracic base (cf ) 

 or a little shorter (9); prothorax nearly similar but shorter, fully 

 one-half wider than long, more strongly arcuate at the sides, the 

 latter h,owever not becoming sinuate basally, except just visibly at 

 the angles, which are acute because of the greater sinuation at the 

 sides of the base; surface similar; elytra scarcely a fourth longer than 

 wide, not at all wider than the prothorax, very obtuse at tip but more 

 angulate toward the suture, the subapical sinus small and feeble as 

 usual in this section; striation similar; interrupted punctures of the 

 eighth stria more on and less to the outer side of the stria than in 

 gravidus. Length (d* 9 ) 7-3~7-5 mm.; width 3.3-3.4 mm. Mis- 

 souri (St. Louis). Two examples taken by the writer. . curtus n. sp. 



Punctured area of the male prosternum very narrow and elongate; ely- 

 tra longer, distinctly more than twice as long as the prothorax ... 3 



3 Body broader, very convex, polished, piceous-black to ferruginous 

 ih color as usual, the under surface more piceous, the abdomen rufes- 

 cent; legs dark rufous; head as in the two preceding; antennae nearly 

 similar, ferruginous; prothorax only two-fifths wider than long or 

 less, the sinuate apex with rounded angles, slightly narrower than 

 the base; sides abruptly evenly reflexed and evenly rounded from 

 apex to base, the angles slightly more than right but very sharp, 

 not prominent; transverse impressions feeble; surface almost com- 

 pletely impunctate, the two foveae at each side of the base widely 

 separated, isolated and having each a few coarse punctures, the 

 outer fovea much the shorter, the carinae very short, obtuse; elytra 

 fully two-fifths longer than wide and always distinctly wider than 

 the prothorax in both sexes, obtusely ogival in apical third; lateral 

 series widely interrupted; striae less coarse or deeply impressed than 

 in the two preceding, the intervals less convex: scutellar stria short, 

 disintegrated as a rule. Length (cf 9 ) 7.8-9.0 mm.; width 3.3-4.1 

 mm. New York (Long Island) and North Carolina (Asheville) to 

 Kansas. Abundant. [Amara furtiva Say] exaratus Dej. 



Body slightly smaller, narrower and more parallel, deep black above, 

 more piceous-black beneath, the legs osbcure rufous; head and an- 

 tennae nearly similar, the strioles deep, oblique; prothorax similar,
