[LeConte 



The species form two groups, quite different in form, the elytra being 

 very distinctly wider than the prothorax in the first. 



A. Last joint of tarsi slightly prominent, claws moderately large, elytra 



wider than the prothorux. 



Scales with bristles intermixed 1. setosus. 



" uniform, without bristles intermixed 2. 



2. Prothorax not coarsely punctured , 3. 



" coarsely punctured 4. 



3. Scales gray, length 4.5 mm 2. limatulus. 



" bronzed, " 2mm 3. aeratus. 



4. Prothorax scarcely wider than long 4 cribricollis. 



" transverse, constricted in front 5. punctatus. 



B. Last joint of tarsi not prominent; body oval 6. ovalis. 



1. E. setosus, .m. sp. 



Dark brown, with scattered short erect bristles, prothorax broader than 

 long, much rounded on the sides, suddenly narrowed and constricted at 

 the tip, deeply and closely though not coarsely punctured, marked with 

 four narrow lines of pale scales having a metallic lustre. Elytra a little 

 wider than the prothorax, elongate ; humeri rounded, not oblique, sides 

 feebly converging behind, tip obliquely narrowed, uniform brown; striae 

 fine, interspaces feebly convex; sides as far as the eighth stria, and under 

 surface, covered with pale scales; antennae and legs ferruginous. Length 

 4 mm.; .16 inch. 



Texas ; Mr. Belfrage. The last tarsal joint is broad, and extends 

 slightly beyond the lobes of the third joint ; the claws are large and 

 divaricate. The prothorax differs in form in the two sexes, in the same 

 manner as in the next species. 



Two smaller specimens are entirely similar to the preceding in form and 

 sculpture, the elytra are covered with dirty gray scales, with a large com- 

 mon discoidal dark brown spot, extending from the base for four-fifths of 

 the length, with prolongations on the third and fifth interspaces, causing 

 the outline to be irregular; there are also two clouds on the sixth inter- 

 space, and one at the humerus. Length 3.5 mm. ; .14 inch. 



Middle States not rare; Kansas, Texas. The prothorax is much more 

 rounded on the sides in the tf than in the 9

 Urn. Gyll., Sch. Cure, iii, 319; Notiodes Urn. ib. vii, 2, 183. 



4. E. seratus, n. sp. 



Smaller, dark brown, covered with gray and brown scales having a 

 'metallic reflection; prothorax a little wider than long, sides rounded espe- 

 cially in front, tip narrowed and constricted, punctures deep and close, not 

 coarse; disc with two brown vittse. Elytra suddenly one-half wider than 

 the prothorax, humeri oblique, obtuse, feebly rounded; striae composed of 

 approximate quadrate punctures, interspaces not convex, disc with a large
