maining three, bowditchi is pubescent, cephalotes is separable 

 at once by the cephalic sculpture and ceneus is much smaller 

 and with angulate clypeus. 



74. D. thoracica n. sp. 



Oblong-oval, brown or ferruginous, shining, the prothorax polished, 

 the elytra with barely perceptible minute alutaceous sculpture, entire 

 upper surface finely rather densely punctate. Mental declivity begin- 

 ning at anterior two-fifths, summit distinctly elevated. Clypeal mar- 

 gin rounded with a feeble median sinuation, rather strongly reflexed, 

 head densely punctate, clypeal suture feebly impressed, especially at 

 middle. Prothorax two-fifths wider than long, sides broadly arcuate, 

 subparallel behind, finely rather densely punctate throughout. Elytra 

 not quite one-half longer than wide, one-fourth wider than the pro- 

 thorax and about two and one-half times as long, scarcely wider 

 behind; costas moderately distinct, each with a row of strong closely 

 placed punctures; intercostae wide, broadly closely confusedly punctate. 

 Body beneath closely punctate at sides, more sparsely and finely at 

 middle. Upper tooth of front tibiae median in position, ungual tooth 

 obliquely truncate, nearly as long as the superior portion of the claw, 

 its tip twice as distant from the base as from the apex of the claw. 

 Length 7.5-9 mm.; width 3.9-4.5 mm. 



I have seen a considerable number of specimens, all from 

 Texas, many from New Braunfels, the others without specific 

 locality. The prothorax is less transverse in this species than 

 in any other known to me. In the males the abdomen is a 

 little concave beneath in outline when viewed from the side; 

 the tarsi are more hairy beneath, and on the hind legs are 

 more evidently longer than the tibiae. 



75. D. arcuata n. sp. 



Oblong-subovate, dark brown or piceous, moderately shining, elytra 

 distinctly, prothorax very minutely, alutaceous. Mental declivity 

 beginning at the anterior one- third or two-fifths, rather steep, strongly 

 margined; clypeal margin arcuate from side to side, no median sinua- 

 tion; clypeal suture distinctly impressed, clypeus densely punctate, 

 front nearly as densely so, the punctures becoming less close at the 

 middle of the vertex. Prothorax three-fourths wider than long, 

 widest at or slightly behind the middle, sides rather strongly arcu- 

 ate, angles all obtuse, punctures rather fine, distant by their own 

 diameters more or less at sides, sparser at middle. Elytra one-fourth 

 longer than wide and not quite two and three-fourths times as long 

 as the prothorax, evidently wider behind; punctuation coarser than 

 on the prothorax, confused in the first intercostal space, more narrowly
