and not densely punctured, punctures round and distinct ; marginal stria 

 short, extending to middle and deeply impressed,* and at humerus a 

 slight trace of an oblique stria. Propygidium and pygidium sparsely 

 and moderately coarsely punctured. Anterior tibiae finely spinulose, 

 middle and hind tibia? ciliate. Prosternum on each side deeply sulcate, 

 median convex portion broadly divided transversely by a deep sulcus 

 ciliate at bottom, anterior division broadly oval, coarsely, but sparsely 

 punctured, posterior portion small, narrow, cariniform. Mesosternal 

 plate coarsely but very sparsely punctured. The two sulci are united in 

 front by a fine transverse groove parallel with, and close to the anterior 

 margin of the prosternum. The lateral ridge of the prosternum is 

 moderately distant from the ridge bounding the sulcus externally, and 

 the space between them is sulciform and smooth. Length .04 inch ; 

 1 mm. 



Occurs abundantly in North and South Carolina. Marseul's name has 

 priority by one year, and must be adopted.

Oblong oval, brown, moderately shining. Head sparsely punctured, 

 front transversely slightly concave. Thorax slightly broader than long, 

 marginal stria deep, lateral sulcus entire, moderately deep, gradually less 

 impressed to base, margin convex, not interrupted, more densely punc- 

 tured at the anterior angles; disc divided unequally by a moderately im- 

 pressed transverse sulcus, anterior portion smaller, and more closely 

 punctured than the posterior, punctures sparsely placed and of elongate 

 form. Elytra strigoso-punctate, more densely near the humeral angles, 

 at humerus a short oblique stria moderately impressed ; marginal stria 

 short basal. Pygidium coarsely and moderately densely punctured. 

 Prosternum as in the preceding species, but with the portion behind the 

 transverse sulcus slightly more distinct. Length .05 inch ; 1.25 mm. 



Occurs from Canada to Texas, more abundant in the Gulf and Southern 

 Atlantic States.

Oblong oval, brownish, shining. Head sparsely punctulate, front 

 transversely slightly concave. Thorax slightly broader than long, mar- 

 ginal stria moderately deep, lateral sulcus entire, marginal space convex, 

 not interrupted, coarsely and rather densely punctured ; disc unequally 

 divided by moderately deep transverse sulcus, anterior portion more finely 

 and densely punctured than the posterior. Elytra coarsely and rather 

 closely punctured, suture slightly elevated, oblique humeral and one 

 dorsal stria short, rudimentary, marginal short basal. Pygidium and 

 propygidium densely and coarsely punctured. Metasternal plate densely 



* Marseul rail- the short stria an internal marginal stria, but from the position of the two 

 striae, I find that the short stria is really the marginal , while the other of which lie speaks, 

 composed ol coarse punctures, is really a portion of the sculpture of the side pieces of the 

 and metastema.
