AMERICAN COLEOPTERA. 73 



arcuate at middle; front closely, clypeus usually a little more densely 

 punctate. Prothorax three-fifths wider than long, sides rather broadly 

 arcuate, subparallel in basal half, punctuation quite dense throughout, 

 the punctures not crowded, however, but separated, as a rule, by less 

 than their own diameters. Elytra three-tenths longer than wide, 

 almost one-third wider than the prothorax and two and three-fourths 

 times as long, rather densely and uniformly punctate, costse distinct, 

 intercostae wide, irregularly punctate, the serial punctures of the costae 

 closely placed and but little finer than those of the wide intervals. 

 Sides of body beneath densely punctate, the punctuation sparser at 

 middle. Upper tooth of front tibias nearly twice as distant from the 

 base as from the apex of the tibia, ungual tooth long, scarcely shorter 

 than the superior portion of the claw its tip barely twice as distant 

 from the base as from the apex of the claw. Length 6.5-8 mm.; 

 width 3.7-4.3 mm.

72. D. basalis n. sp. 



Oblong, scarcely widened posteriorly, rufotestaceous, strongly shin- 

 ing, alutaceous sculpture scarcely visible. Mentum feebly declivous in 

 front from about the middle, declivity feebly margined. Clypeal margin 

 rather widely reflexed, sinuate at middle with angles rounded; clypeal 

 suture distinct, sinuate at middle, punctures of front well separated, 

 of clypeus a little closer but not dense. Prothorax nearly three-fourths 

 wider than long, sides broadly arcuate, subparallel posteriorly, hind 

 angles somewhat obtuse, basal margin impressed from side to side, the 

 impression narrowed a little at middle, punctuation rather dense at 

 sides, a little less so at middle, where the punctures are separated by 

 their own diameters or a little less. Elytra fully three times as long as 

 the prothorax, costae not conspicuous, punctuation confused on the sub- 

 sutural interval, and irregular in basal half on the outer intercostal 

 spaces. Body beneath closely punctate at sides, more finely and 

 sparsely at middle. Upper tooth of front tibias slightly ante-median; 

 ungual tooth broad, obliquely truncate, its apex twice as distant 

 from the base as from the point of the claw. Length 7.5-9 mm.; 

 width 3.9^4.7 mm.
