so in the second and only slightly so in the third. Pygidium sparsely 

 punctured. Body beneath nearly smooth at middle, moderately 

 coarsely but not very closely punctate at sides of abdomen, more 

 closely at sides of metasternum. Upper tooth of front tibia at or a 

 little above the middle. Hind thighs with very few punctures medi- 

 ally, ungual tooth rather slender, post-median, its tip about two-thirds 

 as distant from the apex as from the base of the claw. Length 6.2-7.6 

 mm.; width 3.4-4.3 mm. 



Hab. — Arizona. A single specimen from Phoenix taken by 

 Mr. Wickham, others in the Horn collection without more 

 exact locality. 



The raised margin of the mental declivity is unusually 

 strong for a species of its size; the ungual tooth is also less 

 apical than in other species in this part of the genus. 



76. D. dubia Lee. 



Oblong-ovate, brown, shining, not or with but faint trace of alu- 

 taceous sculpture on the elytra, entire upper surface densely or closely 

 punctate. Mental declivity moderate, beginning at about the anterior 

 third, finely margined. Clypeal margin rotundate, clypeus densely 

 punctate, suture distinctly impressed throughout, arcuate at middle; 

 front evenly broadly subconvex, the punctures close but not crowded. 

 Prothorax not quite two-thirds wider than long, widest just before 

 the base, sides broadly rounded, subparallel toward the base, con- 

 vergent anteriorly; punctuation close throughout, the punctures 

 separated by less than their own diameters, as a rule, at all points, 

 a little sparser along the median line posteriorly, as usual. Elytra 

 two and two-thirds times as long as the prothorax, about one-fifth 

 longer than wide, a little wider behind; densely, moderately coarsely 

 punctate, the costse ill defined, the punctuation confused on all the 

 intercostal spaces, the serial punctures of the costas finer than the 

 others but coarser and closer than usual. Pygidium densely punctate; 

 abdomen densely punctate laterally, closely so medially. Metasternum 

 rather densely punctate at sides, more finely and less closely at middle. 

 Upper tooth of front tibiae small, submedian in position; tarsi more 

 hairy beneath in the male. Ungual tooth subapical, moderately stout, 

 obliquely truncate, its apex twice as far from the base as from the 

 point of the claw. Length 7-7.5 mm.; width 3.9-4.2 mm. 



The LeConte types were taken by Haldeman in Texas. 

 Three examples from the same State are now before me, one 

 from Victoria (National Museum collection), one from Fedor 

 in my own collection, and the third without definite locality in 

 Mr. Schaeffer's collection. The species seems decidedly rare.
