 median channel, its sides or carinse distinctly cutting the sub-basal trans- 

 verse depression, an additional impression on each side near the front an- 

 gles. Elytra striate with rows of coarse, subquadrate punctures ; intervals 

 slightly convex, each with a row of very fine punctures. Length 2-2.2 mm.

 stored. January 11- January 24. A European species, known in

Ovate, subconvex. Usually brown, rarely blackish or 

 brownish-yellow. Thorax larger, subquadrate, sides dis- 

 tinctly converging from front angles to base, disk finely 

 and thickly granulate. Length 1.5-2 mm. (Fig. 244.) 



Marion County; scarce. June 3. Collected by 

 Harold Morrison. Also in Webster collection from 

 Indiana. Occurs throughout the United States. Fig. 244. (After sharp.) 



E. aterrimus Mots., length 1.6-1.9 mm. and E. duplicatus Lee, 

 length 1.9 mm., are both known from Illinois and Michigan. 



E. maculatus Lee, 1.9-2.1 mm., occurs in Ohio and Michigan; 

 E. tenuicornis Lee, length 1.6-1.9 mm., is also recorded from New 

 York and Michigan westward. 



III. Cartodere Thorn. 1859. (Gr., "strength + neck. ") 



Small, narrow, often depressed beetles, having the antennas 

 shorter than head and thorax, their clubs abruptly two- or three- 

 jointed ; eyes small, situated far behind the base of antennas ; thorax 

 without costas, more or less deeply and transversely impressed near 

 base; elytra each with six to eight close set rows of large, rounded 

 punctures; front coxa? distinctly, hind ones widely, separated. 

 One species has been taken in the State and four others perhaps 

 occur but have been overlooked on account of their small size. 

 They live about dwellings, stores or barns in ground cereals, vege- 

 table drugs, or decaying and dust-like vegetable matter.
