H. mibilus. Lee. Pr. Acad., 1855, p. 298. 



A variable species in color and punctuation, but more elongate than 

 any of the preceding. The elytra show hardly any traces of the dor- 

 sal lines. 



Kansas, Colorado, Texas. 



C. — Femora free ; clypeus truncate in front. 

 H. hybridus, Aube, Spec, vi., p. 513; venustus, Lee. Pr. Acad , 1855, p. 

 2!)5.— Ovate, tolerably convex above and below, rufous ; head and thorax 

 punctulate, elytra pubescent black, punctate, slightly transversely rugulose, 

 with a slightly variable orange marking; under surface coarsely and deeply 

 punctate. L. *17 inch. 



Western and Southern States. 



H. mellitus, Lee. Pr. Acad., 1855, p. 299, 73.— Differs in having the cly- 

 peus less distinctly truncate, only the coxal plates beneath deeply punctate 

 and its much smaller size. L. -09 inch. 

 New England, Vermont. 



D. — Small, oblong, depressed, thorax with a basal plica. 

 H. granarius. Aube, Spec, vi., p. 501.— Broadly ovate, form of the first 

 division, head, thorax and legs entirely rufous; elytra greenish-yellow, dis- 

 tinctly punctate; metasternum sparingly punctate, abdomen smooth. L. -05 

 inch. 



Southern States. The ovate convex form at once distinguishes this 

 species. 



H. cinctellus. Lee, Ann. Lye. v., p. 206.— Oblong, black above, antennse, 

 legs and body beneath rufescent; head nearly smooth; thorax rufous in front, 

 base dark, deeply punctate; elytra evidently and closely punctate, with a 

 faint sntural striae; a sub-basal interrupted fascia, and a curved mark towards 

 the apex orange ; ventral surface deeply punctate ; 9 opaque. L. "0G5 inch. 

 California.

 with two orange spots, one under the callus, one beyond the middle. L. -05

Distinct by the evident sutural strife; the surface beneath is en- 

 tirely impunctate as in all the remaining species of this group. 



H. miiiiiidiis. Lee. 1. c. p. 207. — Closely allied to H. subtilis, but more 

 elongate, head smooth, not bi-impressed, more visibly pubescent, more vuri- 

 gated with orange and more finely punctulate. L. "05 inch. 



California. (Leconte.) Distinct by the absence of any sutural
