CETONIIN^E 349 



Pronotal punctures larger, closer and almost uniformly distributed, some- 

 times sparser at base, the surface not strongly impressed medially at 



the sides 3 



3 Hind angles not completely delimited by an oblique impression; 

 pronotal punctures moderately coarse and evenly dense to the basal 

 margin. Body rather elongate, the elytra parallel to very feebly 

 subcuneiform, rather shining, deep black, the erect hairs very short, 

 sparse, moderately coarse, evenly distributed but usually lost on the 

 pronotum, the elytra with a small transverse cretaceous spot at each 

 side behind the middle; head deeply and subconfluently punctate, 

 evenly, feebly convex, very steeply declivous to the abruptly reflexed 

 clypeus, which is truncate from a vertical, evenly arched from an 

 anterior, viewpoint; prothorax barely two-fifths wider than long, 

 larger than in the preceding, subevenly convex, more or less distinctly 

 impressed along the median line, broadly and feebly impressed along 

 the sides, the punctures deep and close-set, not quite so close and 

 rather larger and shallower near the sides; anterior angles with the 

 inner fossa large, cavernous, not extending to the sides, the hind 

 angles but little less than right, sharp, only very moderately retracted 

 and finely, feebly punctate; scutellum with numerous shallow annuli, 

 widely open behind; elytra two-fifths wider than the prothorax, not 

 quite one-half longer than wide, the external angles broadly rounded; 

 surface rather uneven, generally with two broad faint longitudinal 

 impressions and more or less rugose transversely toward the suture, 

 the shallow opaculate areolse very elongate, rather close-set, becom- 

 ing smaller, rounder, deeper and sparser on the upper part of the 

 flanks as usual; pygidium strongly, subevenly convex, with rather 

 small and close-set punctures and minute erect coarse hairs; hind 

 tarsi more slender than in harrisi and almost as long as the tibiae (cf ), 

 shorter (9). Length 10.0-12.4 mm.; width 4.7-6.0 mm. Massa- 

 chusetts (Framingham) to North Carolina (Asheville). [Crem.

5 Body shorter, smaller and more oblong, than in canaliculatus, the 

 pronotal punctures very much coarser, the sparse erect hairs much 

 longer, moderately coarse; elytra sometimes with a small cretaceous 

 spot near each side behind the middle, usually indistinct however; 

 head coarsely, irregularly punctate, the abruptly reflexed clypeus 

 usually with fine punctulation; prothorax short, three-fifths wider 

 than long, feebly impressed along the median line, very feebly 

 impressed along each side behind the subimpunctate swelling just 

 behind the cavity within the anterior angles, which are narrower and 

 less continuous with the sides than in the preceding, the hind angles 

 finely punctulate, much depressed below the general level, the de- 

 pression abrupt; sides converging anteriorly from behind the middle; 

 scutellum with few to many coarse opaque areolae; elytra more or 

 less uneven and subrugose, the large elongate-oval opaque areolae 

 rather close-set, becoming smaller and deeper but still coarse later-
