surHxce alutaceous; head little punctate, deeply foveolate; thorax 

 about as long as broad, si)arsely punctate ; sides more or less 

 transversly rugose ; elytra sparingly punctate, with traces of 

 seriate punctures, and a sutural stria evident behind ; base with 

 a reflexed margin; under side densely but obsolete!}' punctulate. 

 L. .13. Middle and Southern States. 



2. H. curtipennis (Mels.), I- c. n. 4. 



Much smaller; tliorax entirely rugose; eyes very prominent; 

 elytra more strongly punctate. L. .9. Middle and Southern 

 States. 



3. H, marcassita (Zimm. MSS.), sp. n. 



Closely resembling H. pvbescens, but the clypeus is deeply and 

 acutel}^ emarginate in front, with the lateral lobes also prominent; 

 the thorax is not rugose; the form is shorter, the elytra more 

 visibly striate, and the basal margin does not reach the scutellum. 

 L. .12-.13. Middle and Southern States. 



4. H. nebulosus, Leo. 



Also very near H. piihescens and with the clypeus truncate, but 

 the thorax is not rugose, but has smooth reliefs on the disk ; the 

 elytra are more evidently striate punctate ; the pubescence is 

 stronger and more marbled; the basal margin of the elytra is in- 

 complete. L. .13. Kansas, Iowa, and Wisconsin. 



5. H. smaragdulus, Lee. 



Apparently distinct by the uniform metallic green color, but 

 otherwise extremely close to H. nebulosus. 



Glyptoscelis, Lee. 



1. G. hirtus (Oliv.), Ent. vi. 96, p. 906, t. 1. f. 16. 



C3'lindrical, brilliant cupreous, tolerably thickly clothed with 

 a decumbent pubescence of white and brown hairs intermixed ; 

 thorax and elytra deeply and closely punctate, the sides of the 

 former suddenly narrowed towards the base. L. .35-.40. Middle 

 and Southern States, Oregon. 



This may be known by the parti-colored pubescence, and the 

 nearly bare scutellum.
