line of coarse punctures. Elytra densely aciculately punctured at apical 

 two-thirds, punctures extending to the bases of all the interstrise except 

 the inner ; external suhhumeral close to the marginal, short, humeral 

 slightly oblique, internal subhumeral represented by a few punctures ; 

 first dorsal extending beyond the middle, striae 2-3-4 short, subequal, 

 fourth arching at base joining the sutural, which is entire and continuous 

 with the apical marginal. Propygidium coarsely, but sparsely punctured. 

 Pygidium, convex, sides slightly reflexed, surface coarsely and moderately 

 densely punctured. Anterior tibiae finely denticulate, middle and hind 

 tibiae biseriately spinulose. Prosternal striae divergent, strongly ascend- 

 ing, terminating iu front in a fovea. Length, .16 inch ; 4 mm. 



One specimen iu my cabinet from Key West, others will probably occur 

 in Florida.

Black, shining. Head sparsely punctulate, supra-orbital stria- entirely 

 wanting. Thorax smooth at middle punctured at the sides to the ex- 

 treme margin, punctured space narrowest at middle. Elytra coarsely but 

 not densely punctured at apex, punctures forming an irregular triangular 

 space, extending at suture slightly in front of middle ; external subhu- 

 meral short, close to the marginal, humeral very fine, internal subhu- 

 meral short, subapical and moderately deeply impressed ; first dorsal ex- 

 tending four-fifths to apex, 2-3-4, gradually shorter, the fourth arched, 

 joining the sutural which extends two-thirds to apex and thence con- 

 tinued by punctures ; apical marginal line obliterated near the suture, 

 Pygidi urn and propygidium densely and coarsely punctured. Anterior 

 tibiaj finely denticulate, middle biseriately spinulose, hinder spinulose at 

 apex only. Presternum strongly convex, stria; divergent in front, 

 ascending, terminating in a fovea, anteriorly. Length .10-.12 inch; 

 2.5—2 mm. 



Occurs from Pennsylvania to Georgia.

Black, shining. Head finely punctulate, supra-orbital stria sub- 

 obsolete. Thorax smooth at middle, sparsely punctured at the sides. 

 Elytra sparsely but rather coarsely punctured at the apical third ; ex- 

 ternal subhumeral stria absent, humeral fine, internal subhumeral, short 

 apical, separated from the humeral ; first dorsal deeply impressed in its 

 entire length, extending beyond the middle, second somewhat longer, 

 gradually less deeply impressed to tip, third and fourth sub-equal, the 

 latter arching at base, joining the sutural which does not attain the tip of 

 the elytra; apical marginal line obsolete at middle. Propygidium sparsely 

 punctured, pygidium sparsely punctured at base, gradually becoming 

 shorter at apex. Presternum rather acutely convex, striae divergent and 

 ascending. Legs piceo-rufous, anterior tibia; finely denticulate, middle 

 and hind tibia; finely biseriately spinulose. Length .08-10 inch ; 2-2.5 

 mm.
