NORTH AMERICAN COLEOPTERA. 265 



By its convexity and color this species greatly resembles globoms. 

 The general sculpture is rather coarser, the foi"m more elongate and 

 the femora quite different in sculpture. 



Occurs from New York to Florida, but seems rare. 



H. latiis Horn. — Broadly oval, distiuctly narrowed in front, piceous or 

 slightly brownish, feebly shining. Head with coarse and very fine punctures 

 intermixed, not closely placed, a denser group within each eye, clypeus broadly 

 eraarginate. Thorax regularly convex, hind angles very obtuse, basal marginal 

 line distinct near the sides, surface with coarse and fine punctures intermixed, 

 rather sparsely placed and feebly impressed at the middle of the disc, dense and 

 much coarser at the sides, the arcuate and oblique series of coarser punctures 

 scarcely discernible. Elytra with ten entire, moderately impressed striae and a 

 short scutellar row of punctures, strise moderately, coarsely crenately punctured, 

 at the sides much more coarsely, intervals flat, faintly scabrous, the 3-5-7-9 with 

 the usual series of coarse punctures. Body beneath opaque black. Legs piceous 

 or brown, the femora of all the legs densely punctulate and pubescent at basal 

 half, but less in the hind femora, smooth and shining at apex. Length .30 inch. ; 

 7.5 mm. Pi. iv, fig. 5. 



Prosternum with a distinct cariniform elevation near the apex, 

 mesosternum obtusely protuberant, the lower edge of the protuber- 

 ance in form of fl- 



Tarsal claws simple and slender in both sexes. The prosternal 

 carina is but small in its greatest development, and in some speci- 

 mens almost entirely disappears. This species is remarkable in hav- 

 ing a sharp line of demarcation between the densely punctulate and 

 the smooth portions of the femora also in having the basal marginal 

 line of thorax distinct at the sides. 



Occurs at Fort Crook, California. 



H. scabrostis Horn. — Oval, slightly oblong, distinctly narrowed in front, 

 piceous or brown, opaque, or with very feeble lustre. Head coarsely and closely 

 punctate at the sides, smoother at middle, without trace of the arcuate row of 

 punctures, clypeus distinctly emarginate. Thorax regularly convex, a vague 

 depression of the middle of the disc near the posterior margin and a shallow 

 fovea in the place of the puncture seen in other species, hind angles very ob- 

 tuse, basal marginal line distinct near the hind angles, surface coar.sely and 

 densely punctured, rugulose at the sides, smoother at middle. Elytra with ten 

 entire, moderately deeply impressed strife, the scutellar stria entirely wanting, 

 strife coarsely, but vaguely and not closely punctured, intervals flat, granulate 

 or scabrous, disc vaguely depressed each side of suture near apex. Body beneath 

 piceous, opaque. Legs brownish ; posterior femora glabrous, coarsely jmnctate, 

 except for a very small space at base, middle and front femora densely punctured 

 and pubescent one-third from base. Length .20 — .24 inch.; 5 — 6 mm. PI. iv, 

 fig. 6. 



Prosternum finely carinate its entire length, and more elevated in 

 front; mesosternum simple, without frace of jDrotuberance.
