22o MEMOIRS ON THE COLEOPTERA 



evenly trapezoidal, smoother and concave laterally, the sides nearly 

 straight, arcuate basally, the subapical carina less than half as long 

 as the basal width, strongly bidentate, with an intermediate tooth 

 about half the size of the lateral; prothorax rather more than one-half 

 wider than long, the converging sides evenly and rather strongly 

 arcuate from near the base to the apex, rounding in slightly at base, 

 the angles obtuse and slightly rounded, the basal lobe rather strong; 

 punctures small and very remotely scattered, a little larger and 

 less sparse anteriorly throughout the width, wanting in a small post- 

 central area; scutellum longer than wide, very obtusely ogival, 

 impressed longitudinally; elytra not at all, or barely, longer than 

 wide, a sixth (cf) or fourth (9 ) wider than the prothorax and twice 

 as long, parallel, very feebly dilated posteriorly and very broadly, 

 obtusely rounded at apex; punctures moderate, shallowly impressed, 

 each with a distinct annulus, the series nearly as in the preceding; 

 pygidium very transverse in both sexes, finely, closely scabriculate 

 throughout and strongly convex (cf), or flatter and with a large 

 medio-apical area smooth and sparsely punctulate (9), the lower 

 bead entire, moderate and equal in the former, or medially dilated 

 in the latter, sex; elytra of the male duller than in the female. 

 Length (2 cf, 2 9) 11.0-11.3 mm.; width 7.4-7.7 mm. Alabama 



(Mobile) saginatus n. sp. 



Prothorax relatively small; hind tarsi slightly shorter but slender. ... 12 

 12 Body small and very stout, gradually rather strongly inflated behind, 

 shining, pale castaneous-red throughout to black above, the anterior 

 parts always at least with feeble piceous tinge; under surface paler, 

 castaneous, the abdomen and pygidium paler; head very small, 

 barely more than a fourth as wide as the prothorax, rugose, smooth 

 at base, the frontal ridge wholly obsolete, the clypeus more feebly 

 rugose, with basally arcuate oblique reflexed sides, concave laterally, 

 the reflexed subapical carina with two large obtuse teeth and a third 

 very minute between them; prothorax not quite one-half wider than 

 long, trapezoidal, with evenly and rather strongly rounded sides, 

 the punctures small and remote, becoming a little larger and less 

 sparse anteriorly; scutellum nearly as wide as long to narrower, very 

 obtuse at apex; elytra generally rather evidently longer than wide, 

 about a fourth wider than the prothorax in both sexes, very obtusely 

 rounded at apex, the sculpture nearly as in the preceding; pygidium 

 (d 71 ) convex, finely, closely scabriculate but with the apex at the 

 middle less densely so, or ( 9 ) less convex and in great part smooth 

 and sparsely punctate, the lower beading never much thickened 

 medially. Length (23 cf, 5 9) 8.5-10.5 mm.; width 5.8-6.9 mm. 

 The male distinctly smaller than the female, which is relatively 

 much less common. Massachusetts and Rhode Island to North 

 Carolina. [Bothynus castanens Mels.; Podalgus obesus Burm.] 



castaneus Mels. 



Body not quite as small and very much stouter, oblong, convex, shining, 

 black above, with feebly picescent anterior parts, the under surface 

 and pygidium very obscure piceo-rufous; head not so small, nearly a 

 third as wide as the prothorax, not wavy-rugulose as in castaneus,
