56 Coleopterological Notices, III. 



two-fifths longer than wide, scarcely wider than the prothorax, very "broadly 

 and ohtusely ogival at apex ; sides parallel and very feehly arcuate ; humeri 

 slightly obtuse, not at all rounded ; disk not very coarsely but strongly and 

 conspicuously punctate, the punctures sparse and without distinct serial 

 arrangement except on the vertical flanks, where the series are distinct, the 

 punctures approximate. Epipleurae narrow. Abdomen finely, sparsely punc- 

 tate. Legs short. Length 3.2 mm. ; width 1.4 mm. 



Colorado Mr. W. Jiilich. 



This species differs from delicatulus in its shorter, broader form, 

 coarser punctures and radically different punctuation of the elytra. 

 Several specimens. 



EUSATTUS Lee. 



The following form is not at all closely allied to any other thus 

 far described, but may be placed just after robustus in our lists: — 



E. welfrsteri n. sp. — Form and size nearly corresponding with the larger 

 specimens of reticulatus, black throughout, rather strongly convex, glabrous, 

 the pronotum dull and coarsely sericeous, the elytra somewhat shining. Head 

 coarsely, densely punctate, the punctures strongly coalescent and rugulose 

 behind ; antenna? subequal in length to the prothorax, the third joint equal 

 in length to the next two together. Prothorax nearly two and one-half times 

 as wide as the median length, the apex deeply emarginate, two-fifths as wide 

 as the base, the latter transverse, broadly sinuate toward the basal angles, 

 which are acute and slightly prominent posteriorly ; sides strongly convergent 

 anteriorly and very feebly arcuate from basal third, thence to the base nearly 

 parallel and more arcuate ; apical angles anteriorly produced far beyond the 

 eyes, but with the apex rounded ; disk strongly convex, very broadly expla- 

 nate and reflexed at the sides, coarsely, deeply, extremely densely punctate 

 throughout, the punctures longitudinally confluent, and, on the reflexed lateral 

 parts, becoming coarsely rugulose and confusedly confluent. Scutellum dis- 

 tinct, triangular. Elytra twice as long as the prothorax, and, at base, equal 

 to the latter in width, in the middle very slightly wider, scarcely as long as 

 wide ; apex very broadly parabolic ; sides feebly arcuate ; disk convex, almost 

 perpendicular toward the sides and apex ; side margins throughout strongly 

 and unusually widely reflexed, each elytron with three strong acutely elevated 

 costse, which are more or less interrupted, and which do not attain the apical 

 angles, the suture not appreciably costate ; intervals coarsely, sparsely and 

 confusedly punctate, evenly concave, each with a single median row of 

 subelongate distant tubercles. Epipleurae very broad, occupying the entire 

 inflexed sides, strongly impressed near the sides especially toward base ; 

 prosternum granulato-punctate, strongly impressed laterally throughout the 

 length, the hypomera strongly, broadly and abruptly oblique downwards. 

 Legs moderate ; anterior tibiae strongly bent at apex and with a very large 

 oblique terminal spur ; hind tarsi nearly two-thirds as long as the tibia?. 

 Length 15.0 mm.; width 10.3 mm.
