macer, but differs in its more elongate form, especially longer pro- 

 thorax, larger size and darker color. 



In some specimens, especially those with paler pubescence, there 

 is scarcely- a trace of the serial punctures. 



43 H. puiictatissimus Lee— New Spec. Col., 1866, p. 138. — Oblong- 

 oval, subparallel, somewbat depressed, pale brown and dull above, paler rufo- 

 testaceous and polished beneath ; legs and antennae still paler, more flavate ; 

 pubescence extremely dense, short. Head feebly convex, rather finely, densely 

 punctate, the punctures distinctly separated between the eyes, the latter 

 moderately large, separated by three-fourths their width ; antennae stout, 

 rather more than one-third as long as the body, the joints beyond the third 

 just visibly longer than wide, strongly obconical, the third a little longer than 

 the fourth. Prothorax one-half to two-thirds wider than long, the apex about 

 two-thirds as wide as the base, more or less distinctly arcuate ; base transverse, 

 the sinuations almost obsolete ; basal angles very slightly obtuse, not at all 

 rounded ; sides broadly rounded and convergent anteriorly, almost parallel 

 and more nearly straight toward base ; disk excessively finely, densely punc- 

 tate and dull. Elytra about three times as long as the prothorax, and, at 

 the middle, quite distinctly wider ; humeri not exposed at base ; apex rather 

 acutely ogival ; sides nearly straight in basal two-thirds ; disk excessively 

 densely, finely punctured, with fine, feebly impressed rows of slightly larger 

 feeble and scarcely distinguishable punctures. Abdomen polished, finely, 

 rather sparsely punctured, the metasternum somewhat coarsely and densely 

 so, the prosternum and propleurae extremely densely so and dull. Legs 

 moderate in length, the basal joint of the hind tarsi as long as the remainder. 

 Length 4.5-5.3 mm. ; width 1.8-2.2 mm. 



Arizona. 



The fourth joint of the maxillary palpi is rather short and robust, 

 the apex intermediate in length between the inner and outer sides. 



A small species easily known by its excessively dense punctuation 

 and pubescence, the latter being also very short and coarse. 



44 H. deplanatus Champ.— Biol. Cent.-Amer., Coleopt., IV, Pt. i, 

 p. 440. — Oblong, subparallel, rather strongly depressed, feebly shining, pice- 

 ous-brown, the legs and antennae slightly paler ; pubescence coarse, very 

 short, moderately dense. Head small, feebly convex, the punctures distinct, 

 very sparse between the eyes, the latter somewhat large, separated by about 

 two-thirds their width ; antennae stout, rather more than one-third as long as 

 the body, the joints very strongly obconical, the intermediate nearly one-half 

 longer than wide, third distinctly longer than the fourth. Prothorax fully one- 

 half wider than long, the apex strongly arcuate and continuous in curvature 

 with the sides, the latter becoming nearly straight and parallel in basal half; 

 basal angles right, not rounded ; base transverse, the sinuations narrow, some- 

 what distinct ; disk rather finely, densely punctate, alutaceous, the punctures
