2 D. lireTisetosilS n. sp. — Oblong, very feebly convex above ; integu- 

 ments rather sliining, piceous-black, confusedly mottled with rufous, especi- 

 ally toward the sides ; vestiture rather dense, moderate in length, subrecum- 

 bent, confusedly mottled and with numerous very short erect setfe. Heud 

 Very densely pubescent, especially above the eyes and with a deep frontal 

 fovea ; eyes large, feebly convex ; beak in the male two-thirds longer than 

 the prothorax, feebly arcuate, coarsely, deeply, rugosely punctate and longi- 

 tudinally sulcate, with the antennae inserted slightly beyond the middle, the 

 basal joint of the antennal funicle as long as the next three ; in the female 

 the beak is a little more slender, evenly and strongly arcuate, much more 

 than twice as long as the prothorax, smooth, more finely, sparsely punctate, 

 with the antennae inserted a little behind the middle, the basal joint of the 

 funicle as long as the next four. Prothorax not coarsely, deeply, somewhat 

 sparsely punctate, with an impunctate median line ; in the male it is trans- 

 versely oval, slightly narrower than the elytra and about one-third wider 

 than long, in the female smaller, more transverse, more broadly truncate at 

 apex, much narrower than the elytra and about one-half wider than long. 

 Elytra three-fourths longer than wide, the sides straight and parallel in the 

 male or feebly divergent from the base to apical third in the female, the apex 

 obtusely rounded, the sutural notch rather large and distinct ; strial punc- 

 ture rather large, deep, closely approximate ; intervals finely, somewhat dis- 

 tinctly and closely punctate. Ahdomen rather strongly, not densely, unevenly 

 punctate. Length 5.7-7.0 mm. ; width 2.3-2.9 mm. 



Arizona. 



This species is closely related to mucidus, but may be distin- 

 guished by the slig-htly longer beak with the antennae a trifle less 

 apical in insertion in both sexes, by the abundant, erect but short 

 setge, bristling throughout the dorsal surface, and by the relatively 

 more elongate anterior legs of the male, the basal joint of the tarsus 

 in that sex being about equal in length to the remainder; it is dis- 

 tinctly shorter in mucidus.

Oblong, flat above, convex at the sides, somewhat densely clothed 

 with short robust pointed and subrecumbent hairs, which are whitish 

 in color and with barely a trace of sparse and extremely short semi- 

 erect setae toward apex only ; integuments black and rufo-testaceous 

 confusedly mottled. Beak slender in the male, feebly arcuate, 

 coarsely, densely, rugosel}^ striato-punctate, about one-half longer 

 than the prothorax, with the antennae inserted at apical two-fifths, 

 in the female more strongly arcuate, cylindrical, smooth, finely, less 

 densely, confusedly punctate, twice as long as the prothorax, with
