legs and antennae very pale testaceous throughout ; pubescence rather sparse, 

 short and indistinct anteriorly, coarse and recurved, cinereous and distinct on 

 "the elytra. Head small, as long as wide, the eyes small, somewhat prominent, 

 ishe tempora a little shorter, not at all prominent, strongly convergent and 

 evenly arcuate behind them to the neck ; double impression of the vertex deep 

 and bisetulose ; clypeus large, greatly extended and angulate at the sides ; 

 maxillary palpi well developed. Antennse short and stout, much shorter than 

 the head and prothorax, gradually and strongly incrassate toward tip ; second 

 joint almost as large as the first, longer and much thicker than the next two, 

 cylindric-oval, % longer than wide ; three to seven increasing very slowly 

 but gradually in width; seven to ten equally gradually but much more 

 rapidly ; three to five nearly similar, ^5 wider than long ; sixth oval, ^5, 

 seventh more developed externally than internally, ^5, wider than long, the 

 eighth shorter and more transverse, about twice as wide as long ; eight to ten 

 increasing rapidly in length as well as width ; ninth %^ the tenth %, wider 

 than long ; eleventh small, scarcely as wide as the tenth and % longer, rapidly 

 obliquely conoidal in form. Prothorax rather longer than wide, % wider than 

 the head, parallel and strongly rounded laterally, the sides convergent and 

 distinctly sinuate posteriorly ; surface with six subbasal fovese which are 

 rather feeble and imperfectly connected transversely, except in the middle, 

 also with a fovea on the flanks less basal ; lateral carina wholly obsolete. 

 Scutellum extremely minute, visible with difficulty and only under strong 

 amplification. Elytra evenly oval, very convex, widest at the middle, with the 

 sides strongly and evenly arcuate, % longer than wide, not more than twice 

 ■as long as the prothorax and % wider ; humeri altogether obsolete ; subhu- 

 meral impression minute ; inner fovea large and conspicuous ; suture not modi- 

 fied. Legs slender ; femora rather feebly clavate, the anterior only a little 

 more strongly. Length 0.9 mm. ; width 0.38 mm. 



Pennsylvania (Westmoreland Co.). Mr. Schmitt. 



A very small species of rather elongated form, but otherwise 

 closely resembling corpusculum. It may be separated at once, 

 however, b}^ its non-carinate prothorax with the sides not straight 

 and convergent toward base, but sinuate, by its somewhat smaller 

 head with shorter antennae and still more laterally prominent cly- 

 peus, and many other characters. No conspicuous sexual char- 

 acters are observable in the series which Mr, Schmitt has kindly 

 sent me. 



18. S. exiguus n. sp. — Narrowly suboval, moderately ventricose, pol- 

 ished, subimpunctate, dark piceous-brown throughout, the legs and antennse 

 paler, rufo-testaceous ; pubescence sparse anteriorly, short recurved pale and 

 lather sparse on the elytra. Head small, somewhat longer than wide, the eyes 

 well developed, convex, more than twice as long as the tempora, which are 

 strongly convergent, feebly arcuate and not in the least prominent ; vertex 

 transversely impressed, the impression faintly bifoveate at the bottom near
