AMERICAN COLEOPTERA. 91 



Texas. Three examples in the Nationl Museum collection. 

 There are other specimens in the same collection from Mexico, 

 where the species is apparently common and widely dispersed. 

 This little species will be at once recognized by its color, which 

 is quite different from anything else in our fauna. 



94. D. misella n. sp. 



Oblong-oval, rufotestaceous, moderately shining, upper surface 

 rather coarsely punctate, the elytra minutely sub-alutaceous; mental 

 declivity very short and feebly oblique, hind margin not elevated. 

 Clypeus hemihexagonal, broadly roundly emarginate between the 

 sharply defined angles, feebly or scarcely sinuate laterally. Head 

 closely strongly punctate, clypeal suture not impressed, front broadly 

 evenly convex. Pro thorax slightly more than two-fifths wider than 

 long, widest just behind the middle, sides strongly arcuate; front angles 

 obtuse, well defined but not at all advanced; hind angles broadly 

 rounded and indistinct; surface moderately closely rather coarsely 

 punctate. Elytra two and one-half times as long as the prothorax, 

 almost one-half longer than wide; costae not very distinct, very re- 

 motely finely punctate; first intercostal space moderate in width, and 

 confusedly punctured; second and third with nearly regular series of 

 punctures. Pygidium and propygidium not densely punctate, the 

 latter without apical groove. Body beneath rather sparsely not 

 coarsely punctate. Upper tooth of front tibia sub-median; hind thighs 

 impunctate medially; ungual tooth subapical, its tip about twice as 

 far from the base as from the apex of the claw. Length 5.5 mm.; 

 width 2.7 mm. 



Cochise County, Arizona. One example sent by Prof. 

 Snow. Next to pumila this is the smallest species in our 

 fauna. The two may be readily distinguished by the clypeal 

 differences. 



95. D. tenuis Lee. 



Elongate subparallel, rufotestaceous, elytra minutely alutaceous. 

 Mental declivity ill-defined, not margined behind. Clypeus arcuately 

 emarginate at middle, the angles moderately well defined, without 

 external sinuation. Head densely punctate, clypeal suture finely 

 impressed, rather strongly posteriorly flexed at middle. Prothorax 

 three-fifths wider than long, widest just behind the middle, sides 

 strongly arcuate, nearly straight anteriorly; front angles obtuse, not 

 in the least prominent, hind angles broadly rounded and ill-defined; 

 punctuation rather sparse. Elytra very nearly three times as long as 

 the prothorax, one-half longer than wide, scarcely wider posteriorly, 

 costas not very distinct, first intercostal space only with the punctua-
