segments three to five more sparsely so toward base, the fine semi-denuded 

 points not very evident. Legs short and robust, densely clothed, the femora 

 feebly annulate with paler and denser pubescence at apical third. Length 

 9.8-10.5 mm. ; width 4.2-4.8 mm. 



New Mexico. 



The two typical representatives of this species which I have be- 

 fore me are both from New Mexico, and I also refer to it a speci- 

 men from Arizona which is more elongated and parallel with a 

 rather less developed rostral carina and more broadly pubescent 

 median area of the pronotum. 



D. denticollis n. sp. — Moderately robust, somewhat depressed above, 

 elongate-suboval, black and somewhat dull throughout, extremely densely 

 clothed with short recumbent squamiform pubescence, cinereous to ferruginous 

 in color, the erect hairs very short, sparse. Head sparsely punctate ; beak 

 about one-half longer than wide, a little shorter than the prothorax, flattened, 

 broadly bisulcate, very densely pubescent above, the medial carina rather 

 narrow but not acute, moderately elevated. Prothorax fully one-fourth wider 

 than long, widest at the anterior lateral tubercles which are very pronounced ; 

 sides behind them parallel to the base, the latter broadly cusped in the middle, 

 much wider than the apex ; disk very coarsely, unevenly foveolate, broadly, 

 obliquely pubescent laterally and more or less broadly but rather less densely 

 so in the middle. Scutellum very small. Elytra two-thirds longer than wide, 

 much more than twice as long as the prothorax and about one-third wider ; 

 sides feebly arcuate especially behind, obliquely convergent to the apex, the 

 latter narrowly subtruncate ; humeri not much exposed or prominent ; disk 

 with series of moderate sized, rather distinct punctures, the alternate intervals 

 rather strongly elevated, the extremely dense pubescence imperfectly denuded 

 in an oblique spot on each elytron at basal third and posteriorly in a large 

 elongate spot parallel to the side margin from the middle nearly to the apex, 

 also behind the middle near the suture along the second interval. Abdomen 

 extremely densely pubescent, the small denuded points sparse. Legs moder- 

 ately stout, the femora feebly annulate at apical third. Length 9.5-10.0 mm. ; 

 width 4.0-4.4 mm. 



Arizona (Peach Springs). Mr. H. F. Wickham. 



The typical series of five specimens represents a species some- 

 what allied to angularis but differing completely in the general 

 arrangement of the denuded elytral spots, also in its smaller size, 

 narrower and more depressed form and smaller punctures of the 

 elytral series. The general direction of the elytral denudation is 

 longitudinal in this species but is more transverse in angularis.
