Elytra at apical third iudefinitely testaceous. 

 Prothorax very distinctly punctate; prosternum densely punctate. 



Modecri. 

 Form broadly oval and convex ; color rufotestaceous, without metallic lustre ; 

 abdomen piceous. 



Prothorax not distinctly punctured; prosternum punctate atriveiitris. 



Form ovate, a slight gibbosity at the middle of base of each elytron. 

 Prothorax coarsely and moderately closely punctate; color piceous black, 

 shining iiiteiis. 



C. rufipes Linn. — Oblong oval, nearly parallel, moderately convex ; head, 

 thorax and legs reddish yellow, elytra blue, shining. Antennfe as long as half 

 the body, gradually thicker externally. Head smooth, frontal carina obtuse, 

 tubercles distinct, well separated, distinctly limited above by a broadly V-shaped 

 line. Thorax nearly twice as wide as long, sides behind nearly parallel, in front 

 arcuately narrowed to the apex, disc convex, almost absolutely smooth, a deep 

 transverse ante-basal impression, limited at each end by a deep longitudinal im- 

 pression which does not extend anterior to the transverse one. Elytra a little 

 wider at base than the thorax, obtuse, umbone moderately prominent and .smooth, 

 a slight impression within it, disc moderately convex, a long scutellar stria of 

 punctures and nine discal strife of coarse, closely placed punctures, the outer not 

 more distant from the maigin than from the eiglith, intervals narrower than the 

 strife, slightly convex, and with a few minute punctures. Prothorax beneath 

 entirely smooth. Metasternum and abdomen piceous, the latter sparsely punc- 

 tate and with short, sparse pubescence. Length .10 inch. ; 2 5 mm. 



The male has a slight impression at the middle of the apical mar- 

 gin of the last ventral segment and the first joint of the anterior 

 tarsus dilated. 



This common European species has probably been introduced 

 into our fauna, and is now widely scattered over the Atlantic region 

 as far west as Iowa. 



C loiigulst n. sp. — Elongate oval, nearly parallel, moderately convex, pale 

 rufotestaceous, surface with distinct greenish lustre. Antennte half as long as 

 the body, very slightly thicker externally. Head smooth, frontal carina dis- 

 tinct, tubercles small, but indistinct. Thorax nearly twice as wide as long, very 

 little narrowed in front, sides feebly arcuate, anterior angles slightly oblique, a 

 feeble siuuation behind them, disc convex, ante-basal impression moderately 

 deep, abruptly bent toward the base at each end, surface with moderately coarse 

 and unequal punctures, irregularly scattered over the thorax. Elytra very little 

 wider than the thorax, humeri rounded, umbone not prominent, disc moderately 

 long, scutellar and nine discal strife of coarse and rather closely placed punctures 

 which are finer near apex, the ninth not distant from margin, intervals narrower 

 than the strife and with a single row of fine punctures. Prosternum and pleurse 

 smooth. Abdomen sparsely punctate, not pubesceut. Length .10 inch. ; 2.5 mm. 



The last ventral of the male has a feeble impression at apex and 

 the first joint of anterior and middle tarsi dilated.
