86 H. C. FALL. 



sors Lee. is only one of these varieties. It differs from the 

 typical form only in the thorax, being slightly less transverse 

 and less closely punctate. I regard morula Lee. also as a 

 synonym of truncatula; the unique type differing in no way 

 except by its somewhat narrower form. 



88. D. punctata Lee. 



Oblong-oval, dark-brown, shining, elytra very finely alutaceous, 

 prothorax scarcely or barely visibly so. Mental declivity short, begin- 

 ning at or about the anterior one-fourth, margined at summit. Clypeal 

 margin hemihexagonal, the middle truncature sometimes feebly emar- 

 ginate, angles distinct but obtuse and without or with but faint trace 

 of external sinus. Head densely or closely punctate, clypeal suture 

 distinct but not much impressed, a little smoother. Prothorax from 

 three-fifths to two-thirds wider than long, strongly subangularly 

 rounded at middle, the sides nearly straight before and behind, apex 

 nearly equal in width to the base; front angles a little obtuse; hind 

 angles more obtuse but fairly well defined; punctuation rather coarse 

 and sparse and somewhat less sharply impressed than usual. Elytra 

 about two and three-fourths times as long as the prothorax, suboval, 

 sides broadly arcuate; costae not distinct; punctuation rather coarse, 

 confused on the broader intervals, the costae with a row of fine distant 

 punctures. Pygidium sparsely punctate. Body beneath rather 

 coarsely and sparsely punctate, finer toward the middle. Upper tooth 

 of front tibia strong and evidently post-median in position; hind thighs 

 not stout; ungual tooth subapical, its tip nearly or quite three times 

 as distant from the base as from the apex of the claw. Length 7-8 

 mm.; width 3.9-4.4 mm. 



Hab. — Texas (San Antonio, New Braunfels, Marfa and Del 

 Rio), and New Mexico (Roswell and Tecumcari). 



LeConte's type was taken at " Frontera" on the Rio Grande. 

 Punctata is more likely to be confused with truncatula than 

 with any other species, but the latter differs quite constantly 

 in its more finely and closely punctate thorax, the point of 

 maximum width of the latter is more posterior, the pygidium 

 is more closely punctate, the upper tooth of front tibia is 

 in front rather than behind the middle and the hind thighs 

 are stouter. 



89. D. chiricalmae n. sp. 



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

 finely alutaceous, prothorax not evidently so. Mental declivity short, 

 beginning at about anterior fourth, distinctly margined. Clypeal mar-
