South Carolina and New York. Dr. Zimmerman. Piceous, densely covered 

 with moderately long, slightly erect yellowish hair. Head densely punctulate ; 

 antennae with the basal joints testaceous, the 2d and 3d nearly equal in length 

 and thickness, together they are longer than the fourth. Thorax very short, 

 densely punctulate, sides margined, scarcely rounded except at the angles. 

 Elytra tlensely punctured, with very faint traces of three elevated lines. Be- 

 neath piceous, with the legs paler and femora somewhat obscure.

 capite punctulato, thorace obsolete punctulato, lateribus vix rotundatis, subcon- 

 cavis, elytris d^nse punctatis, testaceis:, macula scuteliari, sutura postice, mar- 

 ginequft late infuscatis, antennis fuscis basi pallidis. 2 et 3 asqualibus, coniunctis 

 ito longioribus, pedibus testaceis, femoribus infuscatis. Long. '10 ! 1. 



Abundant in the Northern and Middle States. This species is readily distin- 

 guished by the punctuation of the thorax being l*'ss obvious than that of the 

 head, and by the peculiar marking of the elytra, which are punctured as in the 

 three preceding species, and entirely destitute of raised lines. It cannot be H. 

 pa d i of Europe, as the 3d joint of the antennae is equal in size and thickness 

 to the 2d. If Guerin did not describe the head of II. o b s c u ra as smooth, I 

 should refer my specimens to that species. 



9. H. modest a, oblouio-ovalis, rufo-testacea, dense pubescens, tborace 

 capiteque sublilius pimctiilatis, illo lateribus distincte mar^inatis, elytris dense 

 punctatis, antennarum articulis 2 et 3 asqualibus, 4fo coniunctis lon^jioribus.

South Carolina, Dr. Zimmerman. This species resembles the two preceding, 

 but is smaller ; the head and thorax are equally finely punctulate; the antenna? 

 have the 3(1 joint as long and as thick as the 2d. The side margin of the thorax 

 is distinct and slightly retlexed. 



10. H. p u s i 1 I a, ovali^, nigro-picea, irriieo-pubescens, capite thoraceque 

 punctulatis, hoc lateribus fere rectis, distincte marginatis, elytris sat dense 

 punctatis, macula apicali Icete flava, pedibus testaceis, femoribus infuscatis, 

 antennarum basi flava, articulis 2 et 3 coniunctis 4to longioribus, illo crassiore. 

 Long. 'OS. 



Two specimens, Indiana, near Evansville. This species is more regularly 

 oval than any of tho-e above described ; the antennae, are as in H. fusciceps and 

 picea that is, the 2d joint is evidently thicker than the 3d. 



11. H. collar is, elonzato-oblon'j;a, atra nitida, parce pubescens, thorace 

 rufo, vix punctulato, lateribus subrolundatis, reflexis, elytris minus dense punc- 

 tatis, minime costatis, antennarum articulis 2 et 3 testaceis, sequalibus, 4to 

 coniunctis longioribus, tibiis tarsisque piceis. Long. 'IG. 



Guerin, Spec, et Icon. An. Art. No. 9, p. 4. 



Georgia, three specimens. Very distinct from H. ruficollis, not only by the 

 form of the antennae and thorax, but by the coarser punctuation of the elytra. 

 The thorax is entirely bright yellow, without any tendency to become dark in 

 the middle. The third joint of the antennae is not thinner than the second. 



12. H. bi color, elongato-oblonga, atra nitida, parce pubescens, tborace 

 rufo, parce punctulato, lateribus subrotundatis, latius reaexis, elytris minus 



' dense punctatis, minime costatis, antennis basi tiavis, articulis 2 et 3 asqualibus, 

 4to coniunctis longioribus, pedibus flavis. Long. '15. 



Two specimens, from Georgia. Resembles the preceding, but at first sight 

 distinguished by the yellow feet. 



The two following I cannot identify : 



H. obscura Guerin, Spec, et Icon. An. Art. No. 9, p. 4, and H. ob 1 onga 

 Giier, lb. 13. Fresh evidence is required before the European H. variabilis and
