69. T>. maura n. sp. 



Oblong, subovate, black, moderately shining, the elytra minutely, 

 the prothorax barely visibly alutaceous. Mental declivity beginning 

 about the middle, rather steep, distinctly margined. Clypeal margin 

 broadly sinuate, angles rounded. Clypeal suture fine, less distinct at 

 middle, front nearly flat, punctuation dense. Prothorax two-thirds 

 wider than long, sides broadly arcuate, subparallel in basal half; 

 punctuation rather fine, dense laterally, becoming less close toward 

 the middle, where there is a narrow smooth space posteriorly, which, 

 however, does not reach the basal margin. Elytra three-tenths wider 

 than long, two and two-thirds times as long as and not quite one-fourth 

 wider than the prothorax, slightly widened behind, costse distinct, 

 intercostas all wide and rather closely irregularly punctate. Sides of 

 body beneath rather coarsely closely punctate, metasternum minutely 

 sparsely punctate at middle, abdomen sparsely but much more coarsely 

 so. Upper tooth of front tibias strongly ante-median; ungual tooth 

 stout, obliquely truncate, its tip nearly twice as far from the base as 

 from the apex of the claw. Length 8.7-9 mm.; width 4.7-5 mm. 



Texas (Belfrage). 



70. D. pinguescens n. sp. 



Rather broadly ovate, ferruginous, moderately shining, indistinctly 

 alutaceous, upper surface densely not coarsely punctate. Mentum 

 declivous from just before the middle, declivity strongly margined. 

 Clypeal margin broadly sinuate with rounded angles. Head densely 

 punctate, clypeal suture finely impressed. Prothorax nearly three- 

 fourths wider than long, sides broadly arcuate, subparallel in basal 

 half; hind angles slightly, front angles strongly obtuse, punctuation 

 dense throughout, the punctures, as a rule, closer than their own 

 diameters, even at the middle. Elytra one-fourth longer than wide, 

 a little more than one-third wider than the prothorax and very nearly 

 three times as long, distinctly wider behind; costae rather feeble but 

 evident, the intercostas all wide, three to four times as wide as the 

 costae, closely confusedly punctate. Body beneath densely punctate 

 at sides, this denser coarser punctuation covering all but about the 

 middle fifth of the metasternum. Upper tooth of front tibia distinctly 

 ante-median; ungual tooth long, its tip scarcely twice as far from the 

 base as from the apex of the claw. Length 7.G-S.4 mm.; width 

 4.5-4.7 mm.

71. I), frondicola Say. 



Oblong-ovate, brown or ferruginous, moderately shining, elytra 

 barely visibly alutaceous. Mental declivity beginning a little in front 

 of the middle, distinctly margined. Clypeal margin moderately sin- 

 uate at middle with rounded angles; clypeal suture distinctly impressed,
