Coleopterological Notices, V. 543 



very coarsely punctate. Prosternal lobe narrowly rouuded, margined, finely 

 but densely and deeply punctate laterally ; mesosternum abruptly deeply and 

 circularly emarginate in rather more than median third ; stria entire. Ante- 

 rior tibiae very broad, 5-dentate externally, the apical tooth acute and simple 

 but with a small approximate denticle on the truncate apex. Length 6.6-8.0 

 mm. ; width 4.7—5.1 mm. 



Ore,^on ; Kansas. 



The specimen from Kansas has the pronotum subimpnnctate near 

 the striae and basal angles, but does not appear to differ otherwise 

 from the Oregon types. 



H. fractifroiis. — Somewhat narrowly oblong-oval, moderately convex, 

 very highly polished, the minute punctules very sparse, not much stronger 

 or denser toward the sides of the pronotum. Head a little more distinctly 

 punctulate, the frontal stria narrowly interrupted in the middle. Pmthorax 

 barely twice as wide as long, the sides moderately convergent, broadly and 

 feebly arcuate from base to apex ; marginal stria fine, entire, with two minute 

 interiial punctures ; outer lateral straight, almost entire ; inner sinuate at 

 the middle, subentire ; ante-scutellar stria feeble and extremely short. Elytra 

 not quite one-half longer than the prothorax, and, at basal third, where the 

 sides are somewhat more strongly rounded, slightly wider; apex broadly 

 rounded, feebly oblique; inflexed flanks fiat, strongly but not ver}' coarsely 

 or densely punctate ; outer series of remote punctures distinct, entire ; inner 

 Series between the subhumeral and first dorsal more approximate, distinct, 

 extending to basal third ; outer humeral fine, short, subtransverse ; inner 

 humeral fine, oblique ; subhumeral strong, not quite attaining the base ; first 

 four dorsals entire, strong, the fourth only slightly abbreviated at base ; fifth 

 and sutural very short, apical. Pjgidia rather finely evenly and very closely 

 punctate. Prosternal lobe broadly rounded, finely and feebly margined, 

 finely punctate ; mesosternum abruptly and circularly emarginate in rather 

 more than median third, the stria entire. Anterior tibiae with an external 

 series of about seven small, closely placed teeth, formed principally by the 

 short coarse spinules ; posterior with an outer series of slender spinules and 

 an inner series of stiff setse. Length 5.5 mm. ; width 3.8 mm. 



California (Lake Tahoe) ; Oregon 



A variety of this species with shorter prothorax, much more 

 widely interrupted frontal stria, and with slight but marked 

 divergence in the serrulation of the anterior tibia3, was recently 

 taken by Mr. Wickham in Vancouver. It may possibly be dis- 

 tinct, but I have at present only a single specimen. 



H. inorinoil. — Stout, oblong-oval, convex, very highly polished, the 

 punctules extremely minute, sparse, coarser and distinct near the posterior 

 limit of the inner thoracic stria. Head scarcely more distinctly punctulate, 

 flat, the occiput remotely bifoveate near the thoracic edge ; epistoma very
