apparently very broadly and feebl}- bisiniiate. The head in the 

 female is relatively bnt little smaller, bnt the prothorax is some- 

 what more narrowed toward apex and the elytra just perceptibly 

 and gradually wider behind. The ungual appendages are very 

 short and rudimentary, and the anterior tibiae completely devoid 

 of spinules. I have before me a large series agreeing in every 

 respect with the original type of LeConte. 



10. D. depressiiliis n. sp. — Ovoidal, feebly convex, sinning, black; legs 

 riifo-ferriiginous, the hind thighs, except at tip, black, the anterior and inter- 

 mediate piceons-black ; antennit black throughout; labrum, mandibles and 

 apex of the ejiistoma pale piceo-rufous; pubescence cinereous, rather short, 

 moderately dense, intermingled with a few erect black setfe anteriorly and with 

 more numerous, very short and scarcely distinct erect pale hairs on the elytra. 

 Head rather small, three-fifths as wide as the prothorax, strongly and closely 

 punctate and slightly rugose, the impressions nearly obsolete; labrum feebly 

 arcuate at apex; eyes moderately small, convex; antennae long, filiform, the 

 joints rounded. Prothorax twice as wide as long, the sides parallel, distinctly 

 and almost evenly arcuate, the edges feeljly and finely' crenulate; basal angles 

 obtuse but not rounded, the apical feebly obtuse and not very blunt; apex 

 and base subequal, feebly and almost equally arcuate; disk finely and some- 

 what closely punctate, rugose in a wide and feebly delimited lateral area. 

 Elytra one-half longer than wide, quite distinctly wider at apical two-fifths 

 than at base and about two-fifths wider than the prothorax; apex almost semi- 

 circular; disk finely, evenly and rather closely punctured. Under surface 

 finely and somewhat sparsely luteo-pubescent. Length 2.6 mm.; width 1.25 

 mm. 



Nevada. 



A moderatel}^ large species, readily recognizable by the sub- 

 depressed form, small head, very transverse prothorax and colora- 

 tion of the legs. It is represented in my cabinet by a single 

 female t3'pe.

Suboval, rather narrow and convex, the head and pronotum 

 smooth and polished, the elytra very obsoletely reticulate; body 

 piceous-black, the legs rufo-ferruginous; antenna? blackish-pice- 

 ous, scarcely paler toward base; pubescence moderately long, 

 coarse and dense, closely decumbent, fulvo-einereous in color and 

 Avithout trace of intermixed erect hairs. Head three-fourths as 

 wide as the prothorax, minutely and sparsely punctate ; antennre 

 only moderate in length though subequal to the head and pro-
