coarsely and closely punctate near the base and gradually more finely to apex ; 

 intervals convex, moderately coarsely punctate from the base beyond the middle, 

 but comparatively smooth at apex and sides. Body beneath moderately shining, 

 the metasternum coarsely and moderately closely punctate. Legs rufo-testaceous 

 Length .07 inch. ; 1.75 mm. 



Tliis species resembles, superficially, minntum, but differs in some 

 important details. The sculptnre of the head and thorax is similar. 

 The elytra are son]ewhat more deeply striate and the punctures much 

 coarser, while the punctuation of the intervals is less close and less 

 extended. In mmutvm the metasternum has a well marked oblique 

 line, and the surface otherwise is densely coarsely punctate, in the 

 present species the line is less marked and the punctuation well 

 separated. 



The pale apical region which extends along the sides to middle 

 may not be specific, but varietal. There is no pubescence visible on 

 the unique examined. 



One specimen collected in Ross County, Ohio, was kindly given 

 me by Mr. E. A. Schwarz. 



The following species belongs to the tribe, but has not been posi- 

 tively identified : 



Cybocephalns? iinicolor Motsch.. Bull. Mosc. 1845, iv, p. 364.— Ovatus, 

 convexus, puntatissimus, fulvus, nitidus, palpis longissimis; thorace transverse 

 antice angustato. lateribus arcuatis ; elytris crenulato-striatis; tibiis externe 

 spinosis. Long. 1 ligu. ; larg. S ligu. 



II resemble beaucoup a une Anisotoma, mais il est pentamere. 



De Sitka. 



Mannerheim states that this is jjrobably a Cercyon (Bull. Mosc. 

 1853, iii, p. 110), and the description to me reads very like that of 

 Cryptopleurum minutum when immature. 



Before closing the present paper I desire to express my thanks to 

 those who have kindly assisted its progress by either valuable sug- 

 gestions or specimens. Messrs. Liebeck and Wenzel, associates of 

 our Section ; Dr. Dietz, of Hazleton ; Blanchard, of Lowell ; Dr. 

 Hamilton, of Allegheny; and finally, but by no means least, XJlke 

 and Schwarz, of AVashino-ton.
