AMERICAN COLEOPTERA. 39 



E. ferrugineus, n. sp. — Elongate, sub-parallel, opaque, ferruginous. Head 

 black, thorax broader than long, moderately convex, coarsely but not densely 

 punctured: a lateral carina on each side and a short, longitudinal impression 

 at middle of disc ; sides moderately rounded, feebly sinuate near the hind an- 

 gles. Elytra subpara.llel, moderately convex, with strire of moderately large 

 punctures not attaining the tip, intervals flat, the third, fifth and seventh cari- 

 nate, the third very short, the fifth extending nearly three-fourths, the seventh 

 nearly attaining the apex. Apex of elytra as in the two preceding species. 

 Abdomen coarsely punctured, last segment as in similis. Length .10 inch; 

 2.5 mm. 



Collected by Mr. Belfrage, Texas. 



Easily known by tlie characters given. The thorax is almost a per- 

 fect reprotluc'tion in miniature of that of moestus, except that it is 

 finely crenulate or almost serrate.

Our smallest species, easily known by the hitcous elytral vitta and 

 the total absence of any elevation of the second elytral interval at base. 

 The carina of the fifth interval is feebly marked at humerus. The 

 sides of the thorax are nearly straight or at least feebly sinuate, the 

 hind angles acute but not prominent, the discal channel rather deep 

 and smooth at bottom; on each side a short lateral carina within which 

 is a smooth space. Length .10 inch; 2.5 mm. 



South Carolina, collected by Dr. Zimmerman. 



This may be the species described by Motschulsky (^Etmles 1859, 

 p. 50), under the name Immerosus, and, if so, the latter should have 

 priority. The description of this and others is so vague as to leave 

 considerable doubt of their identity. 



S. sinuatus, Lee. Proc. Acad. 1852, p. 44. 



The front angles of the thorax are more prominent. The sides in 

 front are nearly straight at the anterior third and slightly converge 

 backwards, then slightly rounded and feebly sinuate near the hind 

 ano-les. The second elytral interval is carinate at base. A very 

 faint humeral and sub-apical paler spot is seen. Length .14 inch; 

 3.5 mm. 



One specimen, Tolula, Georgia. 



S. crenatus, Say (Elmis) Long's Exped. II, 275; Lee. Proc. Acad. 1S52, 44. 



Our common eastern species, easily known by its broader thorax 

 with more strongly rounded sides. The disc is channelled and on 

 each side three obtuse tubercles. The entire surface is opaque, and
