short blunt median tooth at apex. Length (9) 15.7 mm.; width 4.9 

 mm. New Hampshire (Hampton) gracilis n. sp. 



Elytra less elongate, twice as long as wide or less, with the coarse punctures 

 laterally very uneven and confluent as usual 7 



7 — Body oblong, moderately stout and convex, sometimes feebly inflated 

 behind the middle, moderately shining, obscure sneous, somewhat 

 cupreous beneath; head nearly as in gracilis, the prothorax similar 

 but shorter and more transverse, with the parallel sides in basal two- 

 thirds generally, straight but sometimes faintly sinuous; surface not 

 evidently tumescent medially and with the ante-scutellar pit evident, 

 sometimes bipunctate; elytra narrowing behind in about apical third, 

 roughly sculptured, with the patches of dense punctures large and 

 very obvious, the elongate callous spots strong; under surface ( $ ) nearly 

 similar, with the impression of the first ventral rather 'distinct, the 

 median tooth of the apical sinus longer and acute or finely aciculate; 

 male with the sternal channels broader, concave, densely sculptured 

 and more hairy. Length 1 3.8-16.0 mm.; width 4.8-5.7 mm. Kansas 

 to Pennsylvania porcatula n. sp. 



Body narrower anteriorly, the elytra rather strongly inflated, convex, nearly 

 similar in coloration, lustre and sculpture, except that the densely 

 punctate patches of the elytra are less impressed, more confused and 

 less definite; head nearly similar though much smaller; prothorax 

 three-fifths wider than long, slightly inflated before the middle, with 

 broadly rounded sides, the latter evidently sinuate in nearly basal half, 

 the basal angles less than right; elytra behind the middle fully a fourth 

 wider than the prothorax, twice as long as wide, the sides broadly 

 arcuate, gradually converging behind in fully apical two-fifths, the 

 apices narrower than in porcatula and more semicircularly sinuate; 

 female with distinct sternal and abdominal axial impressions, the fifth 

 ventral with a smaU shallow apical sinus, the median tooth and lateral 

 lobes very short, the former obtuse. Length (9) 14.0 mm.; width 

 4.7 mm. Florida (Marion Co.) innocua n. sp. 



8 — Form oblong-oval, convex, shining, obscure aeneous, brighter cupreo- 

 aeneous beneath ; head coarsely, densely punctato-rugose, with a small 

 transverse central callous spot, the hairs very small and inconspicuous; 

 eyes unusually large and prominent; antennae but little longer than the 

 head, cupreous ; prothorax large, but little more than one-half wider than 

 long, the sides broadly rounding and converging anteriorly, becoming 

 parallel from before the middle and also evidently sinuate basally; 

 surface rather closely, moderately punctate along the middle, especially 

 in the anterior feebly impressed area, the punctures gradually coarser 

 and close laterally, becoming coarse and crowded near the sides, with 

 a sublateral line of irregular callus but not evidently impressed near 

 the base, the ante-scutellar pit small though deep; elytra but little 

 wider than the prothorax, fully twice as long as wide, faintly inflated 

 subposteriorly, narrowing in apical third ; surface not very rough, with 

 coarse and very confluent irregular punctures laterally, without evident 

 series of punctures, the punctured patches moderate, the callous spots
