82 MEMOIRS ON THE COLEOPTERA 



impunctate as in the two preceding, but with broadly subgeminate 



series of very fine punctures, generally distinct but sometimes 



becoming obsolete; tarsi not quite so elongate, with the same 



sexual differences; lateral margins rather broadly bright violet, 



not at all blue. Length 25.5-29.5 mm.; width 10.0-12.2 mm. 



North Carolina (Southern Pines), Manee . . carolinensis n. subsp. 



Sides of the prothorax and general features nearly as in depressus but 



a little smaller, not quite so stout, somewhat more convex and more 



polished black, the head nearly similar, the mandibles as in depressus, 



the labrum nearly similar; prothorax much shorter, four-fifths wider 



than long, the subbasal impressions shorter and deeper, the more 



lateral wholly wanting, with the surface even and convex; elytra 



distinctly narrower and more convex, impunctate though with feeble 



vestiges of costae, which become wholly obsolete laterally; hind 



tarsi in the type slender, fully as long as the tibiae or a little longer; 



lateral margins more deeply concave, violet in color. Length 26.5 * 



mm.; width 10.4 mm. Pennsylvania (Carlisle Junction), A. B. 



Champlain. A single example, probably male. . . champlaini n. sp. 



Sides of the prothorax more converging posteriorly, becoming strongly 



sinuous, so that the sides are parallel for a considerable distance 



from the angles 13 



13 Elytra without trace of serial punctures, the lateral margins black. 

 Surface shining, the form narrower than in depressus or its related 

 forms; mandibles perfectly smooth, the labrum transversely truncate 

 throughout the width, with scarcely a trace of lobation; lineiform 

 depressions of the head rather broadly impressed; prothorax one- 

 half wider than long, the lateral groove deeply attaining the basal 

 angles, the basal groove strong, equal and entire, attaining the angles; 

 stria fine, the middle pair of subbasal impressions alone visible and 

 rather feeble; elytra oval, with rounded sides, two-fifths longer than 

 wide; hind tarsi in example at hand slender, about as long as the 

 tibiae. Length 26.0 mm.; width 10.0 mm. North Carolina (Ashe- 

 ville). A single specimen apparently but not certainly male, 



taken by the writer morio Lee. 



Elytra with geminate series of punctures, the side margins colored. ... 14 

 14 Body large, shining and much depressed, more so than in depressus, 

 rather less depressed in the female as usual, the hind tibiae (cf) with a 

 large internal brush of dense hairs at apex, deep black, with broad 

 and strongly violet concave side margins; head much larger than in 

 depressus or allies, the two impressions deep, the mandibles (cf) 

 partially strigose, with unusually long slender part beyond the tooth, 

 or ( 9 ) smaller, with shorter apical part and strigose almost through- 

 out; labrum with very broad and feeble median lobe; prothorax one- 

 half wider than long, the lateral groove lost at base in a large depres- 

 sion extending from the subbasal median impressions toward the basal 

 angles, the stria fine; basal groove nearly entire, lost at the angles; 

 elytra formed nearly as in depressus but still broader and more 

 rounded at the sides, the punctures of the series extremely fine and 

 rather widely spaced but apparently always visible; hind tarsi (d 71 ) 

 rather slender, almost as long as the tibiae, or ( 9 ) a little stouter and
