AMERICAN COLEOPTERA. 2 1 



erect setae. Head densely cribrate punctate, clypeus moderately 

 widely reflexed, broadly emarginate or subtruncate, the angles obtuse 

 but fairly well defined with slightly rounded vertices; front nearly flat 

 without elevations or impressions. Prothorax nearly or quite twice 

 as wide as long, widest near the base, sides very broadly rounded and 

 a little convergent in front, angles all obtuse; disk very coarsely 

 punctate, the punctures nearly in mutual contact as a rule; base with' 

 marginal impressed line Elytra a little more than three times as 

 long as the prothorax, one- third longer than wide; discal costae indis- 

 tinct, punctate, the intercostal spaces with dense, coarse, confused 

 punctures. Beneath less coarsely but equally densely punctate, ex- 

 cept along the median line of the body. Propygidium without apical 

 groove. Tibial teeth subequidistant, the upper nearly twice as far 

 from the base as from the apical tooth. Claws cleft, the inferior 

 portion a little shorter and stouter. Length 7.6-8.4 mm.; width 

 3,9-4.3 mm. 



Habitat. — Texas. One example from Columbus (Hubbard 

 and Schwarz) and three others without definite locality. 



9. D. puberula Lee. 



Oblong, scarcely wider posteriorly, dark brown, upper surface 

 polished with scarcely a trace of alutaceous sculpture, sparsely hairy, 

 the hairs erect and - averaging in length one-half the width of the 

 scutellum or slightly less. Declivity of mentum beginning at the 

 middle of its length, the raised line rather feeble or imperfect, accom- 

 panying setae about eight in number, anterior suture curved forward 

 a little at middle, the basal margin of the ligula elevated and a little 

 prominent along the arcuation. Head densely moderately strongly 

 punctate, the front broadly feebly impressed at the middle, obscuring 

 the clypeal suture, which is distinct laterally. Clypeal margin either 

 truncate at middle with fairly distinct angles or broadly rotundate. 

 Prothorax very little less than twice as wide as long, widest just before 

 the base, not much narrowed in front, the sides broadly arcuate; disk 

 closely not coarsely punctate, basal margin narrowly impressed, 

 angles obtuse. Elytra three times as long and one-fifth or one-sixth 

 wider than the prothorax; rather densely and evidently more coarsely 

 punctate than the thorax; discal costas feeble, the first more evident; 

 intercostal areas confusedly punctate; sutural interval with an ir- 

 regular series of finer punctures; costas with single rows of somewhat 

 finer punctures which are as approximate as the larger ones of the 

 geminate striae. Beneath rather densely punctate; propygidium with- 

 out apical marginal groove. Teeth of anterior tibiae small and ob- 

 tuse or feebly developed, the posterior a little more remote, and twice 

 as distant from the base as from the anterior tooth. Claws cleft at 

 tip, the inferior portion stouter but scarcely shorter. Length 8-8.5 

 mm.; width 4.1—4.4 mm.
