slightly larger, separated by not quite twice their widths medially, 

 becoming notably coarser and densely crowded but not polygonal 

 laterally, the transverse line of tumescent punctures rather less 

 marked than in punctatus. the surface thence to the scutellum more 

 concave and with a fine impressed and more impunctate median 

 line; elytra longer, fully a third longer than wide, more gradually 

 narrowed behind to the narrowly and feebly lobe-like tip, the 

 punctures fully as coarse and closer, separated by evidently less 

 than their own widths; under surface punctured nearly as in punc- 

 tatus, the metasternum however rather less coarsely and closely. 

 Length 1.95 mm.; width 1.05 mm. Virginia (Lee Co.). 



virginicus n. sp. 



Smaller species, narrower than in punctatus, more evenly oval, convex, 

 black and less shining, the vestiture similar; head with rather coarse 

 and deep, polygonally crowded punctures; prothorax three times as 

 wide as its shortest length, the converging sides feebly arcuate, the 

 advancing angles acute; surface with rather strong deep punctures, 

 which are evidently smaller than those of the head and elytra and 

 separated by one-half more than their own widths medially, be- 

 coming much denser but only a little larger laterally, rather finer 

 behind two feebly marked lines proceeding somewhat obliquely and 

 transversely from near the middle point of the finely impressed and 

 subentire median line; scutellum slightly longer than wide, punc- 

 tured nearly like the pronotum; elytra barely a fourth longer than 

 w.ide, the sides feebly arcuate, more rounding basally and more 

 gradually converging and arcuate in more than posterior third than 

 they are in punctatus, the apex narrow and more acutely rounded; 

 punctures rather coarse, very deep but impressed, separated by 

 barely half of their own diameters; abdomen densely dull, in struc- 

 ture and sculpture nearly as in the preceding, the deeply sulcate 

 prosternum with deep, nearly perforate punctures, separated by 

 barely one-half more than their own widths. Length 1.6 mm.; 

 width 0.85 mm. Texas (Austin) austinianus n. sp. 



5 Oblong-oval, rather shining, black, feebly senescent anteriorly, the 

 pubescence short, coarse, subdecumbent, fulvous, mottled on the 

 elytra with ill-defined cinereous spots; head deeply, densely punctate, 

 the punctures obliquely subcoalescent on the vertical part of the 

 front: prothorax much more than twice as wide as its median length, 

 the sides moderately converging and broadly arcuate throughout, 

 the punctures rather fine, separated by more than twice their own 

 diameters, each attended by an extremely minute punctule along- 

 side, the punctures becoming a trifle closer in a median area in basal 

 half, which is limited anteriorly by just visible and transversely 

 oblique subtumid lines, the punctures laterally moderately large 

 and deeper but scarcely closer, being still separated by nearly twice 

 their widths; scutellum moderate, punctured like the adjoining 

 pronotum; elytra oblong, less than a fourth longer than wide, 

 obtusely rounded behind, the apex with a narrow and feeble sub- 

 truncate lobe, the sides nearly straight thence in basal three-fifths, 

 except at the slightly prominent humeri; punctures coarse, very
