and not denselj'^ punctured, punctures round and distinct ; marginal stria 

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

 slight trace of an oblique stria. Propygidiuni and pygidium sparsely 

 and moderately coarsely punctured. Anterior tibia? finely spinulose, 

 middle aud hind tibite 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, nai'row, cariniform. Mesosternal 

 plate coarsely but very sjiai-sely punctured. The two svilci are united in 

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

 margin of the pi-osteruum. 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 deeji, gradually less 

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

 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 jiunctured. 

 Prosternum as in the i)receding species, but with the ijortiou 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 punctui-ed than the posterior. Elytra coarsely and rather 

 closely ipunctured, suture slightly elevated, oblique humeral and one 

 doi'sal stria short, rudimentary, marginal short basal. Pygidium and 

 propygidium densely and coarsely punctured. Metasternal plate densely 



* Marseul calls the short stria an intf.rnnl marginal stria, but from tlio position of the two 

 strije, I find that the short stria is really tho mai-ginal, while the other o*«which lie speaks, 

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

 meso- and metastcrua.
