June, is 9 s.] Casey : North American Coleoptera. 75 



more broadly on the flanks, the elevations polished. Length 5.2 mm.; width 

 1.6 mm. Arizona (Seligman) amplus, sp. nov. 



Elytra rather sparsely and strongly granose on the declivity ; intervals separating the 

 punctured series alternating in prominence; punctures of the series subtrans- 

 verse, subcoalescent and not well defined. North Carolina. . . porcatUS Lee. 



7 — Punctures of the elytral series confluent, opaque and not well defined. Head 

 transverse, opaque and granulose ; eyes small ; antennae short, dark rufous, the 

 club not paler. Prothorax nearly as in pacijieus, the rasal angles less rounded. 

 Elytra about twice as long as wide, slightly wider than the prothorax and much 

 more than twice as long; sculpture very dense, the surface densely opaque; 

 erect hairs moderate in length, stiff and fulvous. Abdomen rather dull, finely, 

 sparsely punctulate. Length 3.0-4.0 mm.; width 0.9-1.2 mm. Virginia (Nor- 

 folk) opacus, sp. nov. 



8 — Elytral punctures confused in arrangement, at least toward the sides and suture. .9 



Elytral punctures forming perfectly even series throughout the width, the intervals 

 even 12 



9 — Apical declivity of the elytra granulose, the punctures more close-set throughout. 10 



Apical declivity simply punctate 11 



10 — Elytral punctures distinctly asperate throughout. Body and legs blackish, the 

 antennae rufo-piceous ; surface moderately shining. Head short, not very 

 densely granose. Prothorax not quite as long as wide, the sides feebly conver- 

 gent from near the broadly rounded basal angles, merging gradually into the 

 broadly rounded and moderately serrulate apex ; surface sparsely, rather strongly 

 asperate anteriorly, more closely granulate toward base, the granules flattened, 

 less dense laterally. Elytra about two-thirds longer than wide, twice as long as 

 the prothorax and scarcely wider ; punctures not very coarse, serial in arrange- 

 ment, the intervals flat and even ; apex evenly convex, strongly grano-tubercu- 

 lose. Abdomen shining, sparsely punctulate. Length 3.7 mm.; width 1.2 

 mm. New Jersey h ispidulus , sp. nov. 



Elytral punctures circular, not asperate on the disk and toward the suture, feebly 

 granuliferous on the convex declivity ; elytra polished, the intervals flat ; serial 

 arrangement of the punctures only observable along the middle of each elytron. 

 SouthCarolina densus Lee. 



Elytral punctures abnormal, not rounded but somewhat dilated at their posterior 

 limits, serial in arrangement and well separated, more confused near the suture 

 and broadly toward the sides, not granulose except posteriorly and on the de- 

 clivity. Body evenly cylindrical, shining, dark piceous, the elytral vestiture 

 sparse, stiff and erect. Head nearly smooth, constricted at base as usual. Pro- 

 thorax nearly as long as wide, oval, asperulate anteriorly, the basal angles 

 rounded ; disk with the flattened and nearly contiguous tubercles toward base 

 small. Elytra perfectly cylindrical, barely twice as long as the prothorax and 

 perceptibly wider, not quite twice as long as wide, polished. Length 2.4 mm. ; 

 width 0.7 mm. Pennsylvania. ; parvulus, sp. nov. 



II — Dark rufo-piceous, the elytra blackish, highly polished with rather small and 

 simple punctures, which are only feebly subserial in arrangement, becoming 

 very small and feebler on the flanks and simple on the declivity. Indiana and 

 South Carolina cribratus Lee.
