AMERICAN COLEOPTERA. 85 



upper tooth at about the basal third. Hind thighs very stout, hind 

 tibia? stout, a little shorter than the femora. Ungual tooth subapical, 

 evidently shorter and not appreciably stouter than the superior portion 

 of the claw, its tip about two and one-half times as distant from the 

 base as from the apex of the claw. Length 9.1 mm.; width 4.6 mm. 



Hab. — Texas. 



The type and only representative of this very distinct 

 species is in the Horn collection. 



87. D. truncatula Lee. 



Oblong-subovate, dark piceous brown, more rarely red-brown, mod- 

 erately shining, elytra finely, the prothorax minutely alutaceous. 

 Mental declivity beginning at about the anterior one-third or two- 

 fifths, posterior margin distinctly elevated. Clypeal margin truncate 

 and feebly sinuate at middle, the angles well defined but obtuse, with- 

 out or with but faint trace of sinuation. Clypeal suture well impressed, 

 often a little smoother, head elsewhere densely punctate. Prothorax 

 very nearly two-thirds wider than long, widest at posterior one-third 

 or two- fifths; sides broadly rounded and convergent in front, hind 

 angles very obtuse, rounded, scarcely defined; punctuation rather fine, 

 moderately close though somewhat variable. Elytra rather less than 

 two and three-fourths times as long as the prothorax, slightly more 

 than one-fourth longer than wide, feebly wider behind; costas distinct, 

 very remotely and finely punctate, all the intercostae wide and con- 

 fusedly moderately coarsely punctate. Body beneath punctate about 

 as usual, the punctures at sides moderately coarse but not very dense. 

 Dorsal and ventral segments separated by a raised line. Upper tooth 

 of front tibia? slightly ante-median, more distant from the middle tooth 

 than the latter is from the apical one. Hind thighs stout, very sparsely 

 punctate at middle. Ungual tooth subapical, broad and almost 

 squarely truncate, its tip about twice as distant from the base as from 

 the end of the claw. Length 6-7.4 mm.; width 3.3—4 mm. 



Hab. — Kansas, Texas and New Mexico. 



The type, as well as almost all other specimens seen, are 

 from Texas — for the most part without specific locality. Mr. 

 Wickham has found it as far west as Alpine, and it has been 

 taken at Brownsville by most of the collectors who have 

 visited that place in recent years. The New Mexico specimen 

 was taken at La Trementina and sent me by Prof. Cockerell, 

 but it is not typical, the prothorax being widest at about the 

 middle. There is considerable variation in the form and 

 punctuation of the thorax, and I feel almost certain that con-
