 p. 273 (Scydmseniis). 



Rather narrow, polished and impuhctate, black, the elytra dark 

 ruby-red, becoming black on the flanks and tovy^ard tip ; legs and 

 antennse dark rufous ; the femora blackish ; pubescence long and 

 rather abundant, darkish in color. Head distinctly wider than 

 long, the eyes not very well developed and but moderately con- 

 vex ; clypeal tooth minute and triangular. Antennse rather thick, 

 not longer than the head and prothorax, the club abrupt, rather 

 thick and with its joints gradually increasing in width; second 

 joint slightly obconic, nearly twice as long as wide, as long as the 

 next two together and distinctly thicker; third, fourth and sixth 

 subequal and scarcely at all longer than wide ; fifth very slightly 

 elongate ; seventh but little thicker, cylindric, as wide as long ; 

 eighth \ wider than the seventh and not quite as long as wide; 

 ninth and tenth progressively slightly wider and quite distinctly 

 shorter than wide ; eleventh still thicker, obliquely pointed, not 

 as long as the two preceding. Prothorax conic, the sides notice- 

 ably arcuate, not longer than wide ; apex barely ^ as wide as the 

 base, the latter |- wider than the head ; surface convex and per- 

 fectly even. Elytra rather less than ^ longer than wide, twice as 

 long as the prothorax and | wider, the sides evenly arcuate; apex 

 narrowly obtuse ; humeral plica somewhat short but strong, the 

 impression correspondingly abbreviated but rather distinct ; fovese 

 small; subsutural impressions distinct, the suture very finely and 

 faintly elevated near the base. Legs rather short and with some- 

 what conspicuous pubescence, the femora moderately strongly 

 clavate,the intermediate and posterior equally strongl3^ Length 

 1.4 mm.; width 0.55 mm. 



Pennsjdvania (probably near Philadelphia). Closely allied to 

 fossiger in general form, coloration and in the minute clypeal 

 tooth, but difiering in its smaller size, narrower form, stouter and 

 more abbreviated antennse and stronger subsutural impressions. 

 Three specimens of indeterminate sex are before me. 



There can be but little doubt that Say had before him this 

 species in describing hrevicorne. The species identified under 

 that name by LeConte is however a widely different thing, not 

 agreeing at all with Say's description, either in coloration of 

 the body or nature of the pubescence ; it will be described subse- 

 quently under the name clavicorne. Say states that hrevicorne
