COLEOPTERA. 71 



sL'ta ; lateral borders very narrowly reflexed ; modian groove very fine and 

 feeble; near tlie base there is a broadly arcuate row of minute punctiform 

 loveae, nearly in mutual contact ; there is also a minute tuberculation just 

 inside of each basal angle. Scutellum small, angulate behind, very slightly 

 wider than long, sides rounded, slightly constricted at base. Elytra at base 

 just visibly wider than the pronotum ; sides parallel and rather strongly 

 arcuate for two-thirds the length from the humeri, thence rather strongly 

 convergent ; disk rather acutely rounded behind, widest at one-third the 

 length from the base, where it is scarcely two-fifths longer than wide ; 

 humeral angles broadly rounded ; strongly convex, impunctate ; sutural 

 striae distinct, fine, single, slightly arcuate, with excessively feeble traces of 

 a second stria ; there are also on each elytron two punctiform impressions at 

 the base, and two extremely minute and feeble punctures or eroded setiger- 

 ous impressions at one-third the width from the suture, and just before and 

 behind the middle ; lateral edges narrowly rellexed ; on the extreme Hanks 

 near the humeri there is on each side a short irregular impressed channel, 

 with two or three setigerous punctures near its point of origin ; epipleurae 

 wide at the base, becoming rather abruptly much narrower at one-third the 

 length from the humeri, pale in color. Abdomen nearly flat, edges of the 

 segments abruptly and very narrowly paler. Legs long and slender. 

 Length 2.0 mm. 



Pennsylvania, near Pliihulelphia, 2. 



A very robust little species, resembling incurvus, but much shorter 

 in proportion to its width ; tlie greatest difference is perhaps in tlie 

 head, which is much shorter and broader and with much more coarsely 

 granulated eyes in glossema; tlie distance between the front coxaj is 

 also relatively greater in the latter. 



B. gemellus n. sp. — Form very slender, convex ; sides arcuate. Above 

 very uniformly dark rufous throughout, antennae testaceous toward base, 

 fuscous toward tip ; under surface throughout of same color as the upper, 

 except along the lateral margins of the abdomen, where it becomes castane- 

 ous ; integuments polished, rather opaque ; legs flavate, translucent. Head 

 rather small, as long as wide ; eyes moderate, somewhat prominent, coarsely 

 graniilated ; impressions above the eye near the suture very feeble ; epis- 

 tomal apex slightly longer than one-third the distance between the eyes, 

 very feebly sinuate, angles obtuse and slightly rounded, sides thence widely 

 divergent and feebly sinuate to the anterior limits of the eyes ; labrum large, 

 about twice as wide as long, minutely and strongly reticulated throughout, 

 apex broadly sinuate ; epistoma about one-half wider than long, setae at 

 about one-third its length from the anterior angles ; antennae short, scarcely 

 as long as the head and prothorax together, basal joint robust, second 

 slightly shorter than the third. Prothorax widest at two-fifths the length 

 from the apex, where it is much wider than the head, and one-half wider 

 than long ; sides broadly and moderately arcuate to within a very short 

 distance of the basal angles, where they become very feebly sinuate ; basal
