Louisiana; for this very interesting species I am indebted to my friend Dr. 

 Schaum. The pubescence will distinguish it from the other species, having a 

 basal stria common to the thorax and elytra. The sides of the thorax are slightly 

 rounded, and form with the elytra a scarcely perceptible angle.

 tiliter pubescens, thorace subtiliter punciulato, margine basali nigricante. striola

Ne.w York? given me by Mr. Willcox. The sides of the thorax are rounded, 

 and form a moderately distinct, but very obtuse angle, with the elytra; the an- 

 terior fascia of the latter is one-third from the base, and consists of a marginal 

 spot and a smaller discoidal one ; the second band is at one-third from the tip, 

 and is straight and regular, extending nearly to the suture ; the elytra in the 

 only two specimens seen are moderately shining, finely and very densely punc- 

 tured, but probably vary according to sex. 



20. H. 12-1 i n e a t u s, appears allied to H. alpinus and other European species. 

 The female resembles closely the figure of H. bidentatus (Aube, Col. Eur. 5, pi. 

 28.) H. laevis Kirby appears to be the same, but he states that no punctures are 

 visible on the upper surface of the body. In comparison with H. alpinus, our 

 species is a little narrower, and the sides of the thorax are less curved anteriorly. 



21. H. scitulus, oblongus, postice subacutus parum convexus, niger subni- 

 tidus glaber, capite thoraceque testaceis, punctulatis, punctis maioribus sparsis 

 intermixtis, hoc versus latera utrinque impresso ad basin transversim subdepresso, 

 margine apicali et basali nigricante, disco fasciis duabus subinterruptis extror- 

 sum connexis ornato, elytris margine basali ad humeros dilatata, laterali 

 lineolisque pluribus flavo-testaceis ornatis, parce punctatis, utrinque fortius bi- 

 seriatim punctatis, pedibus piceo-testaceis. Long. -13. 



One specimen, Eagle Harbor, Lake Superior. Allied to H. septentrionalis of 

 Europe, but more acute posteriorly, much darker colored above, more coarsely 

 punctured, and with the two punctured lines of the elytra distinct. The thorax 

 is broadly rounded on the sides, and forms a distinct angle with the elytra. 



22 H. st ri a t el lus, varies in color from the black type, with indistinct 

 testaceous elytral markings to dull muddy testaceous, with short lines on the 

 elytra, two discoidal thoracic spots, and the sides of the head fuscous. The under 

 suiface is black, and the feet dull testaceous, with the posterior tbighs dark. 

 The impressed striae of the elytra are four on each, and are usually deep, but are 

 sometimes shallow, though always distinct. It is found at San Francisco and 

 San Diego, in California, and at Sinta Fe in New Mexico. 



23. H. venustus, ovalis convexus, postice attenuatus, confertim subtiliter 

 punctatus, pubescens, ferrugineus, clypeo ad apicem late truncato, lateribus ob- 

 liquis, thorace versus angulos postico3 vage impresso, elytris atris, ad medium 

 paulo latioribus ad apicem oblique subtruncatis, margine fasciis duabus undu- 

 latls, maculaque versus apicem testaceis. Long. -17. 



One specimen from North Carolina given me by Mr. Zimmermann. Very dis- 

 tinct from all others by the hemi-hexagonal form of the clypeus, which is oblique 

 each side, and truncate at the apex, with the angles well marked, and the edge 

 very slightly reflexed. Head and thorax densely finely punctured ; the latter 

 slightly rounded and distinctly margined on the sides; posterior angles rectan- 

 gular, broadly vaguely impressed ; the sides make a very obtuse, not very per- 

 ceptible angle with the elytra. These are black, densely punctured, finely pubes- 

 cent, moderately convex, broadest about the middle, then narrowed to the apex, 

 which is obliquely truncate ; the whole margin, two undulated fasciae not
