sparsely punctate medially, not very closely so laterally. Upper tooth 

 of front tibia strong, slightly post-median. Ungual tooth post-median, 

 evidently shorter than the upper portion of the claw, not very stout, 

 obliquely truncate, its apex scarcely twice as distant from the base as 

 from the point of the claw. Length 7-7.5 mm.; width 3.8-4 mm. 



New Mexico (Albuquerque and Cloudcroft). 



Two examples only of this species have been seen, that 

 from the first named locality, collected by Wickham, the 

 other by Viereck and now in the collection of the Philadelphia 

 Academy of Sciences. 



The almost complete absence of the serial punctures of the 

 elytral costae — except near the apex — is a very unusual char- 

 acter noticed elsewhere only in atratula. 



91. D. confusa n. sp. 



Oblong-ovate, rufotestaceous, moderately shining, the elytra dis- 

 tinctly finely alutaceous. Mental declivity fairly distinct, beginning 

 a little in front of the middle, feebly or not at all margined behind. 

 Clypeus emarginate at middle, angles sharply defined and prominent, 

 with usually a slight external sinus; surface broadly convex at middle, 

 feebly concave at sides, punctuation close but not crowded; suture 

 moderately strongly impressed, arcuate at middle; front distinctly 

 broadly impressed or concave at middle behind the clypeal suture; 

 punctures separated by their own diameters or less, becoming a little 

 sparser on the vertex, the occiput smooth at least in part. Prothorax 

 about three- fifths wider than long, widest at or just behind the middle, 

 sides strongly rounded, straight or faintly sinuate anteriorly; front 

 angles obtuse, not prominent, hind angles more broadly obtuse; punc- 

 tuation less close than on the head, the punctures separated by from 

 one to two times their own diameters except near the anterior margin, 

 where they are more densely placed; median lateral foveae rather 

 deep, the others faint or lacking. Elytra barely two and one-half 

 times as long as the prothorax and about one-fourth longer than wide; 

 costas distinct, first interspace wide, confusedly punctate; second 

 narrower, punctuation variable, confused throughout its length in the 

 type, but only very slightly so or only toward the base in others; 

 third with punctuation usually a little more irregular than in the sec- 

 ond. Propygidial marginal groove nearly obsolete, pygidium mod- 

 erately closely punctate. Body beneath rather finely and sparsely 

 punctate. Upper tooth of front tibiae at or a little in front of the 

 middle; ungual tooth subapical, rather stout, obliquely truncate, its 

 apex about twice as far from the base as from the point of the claw. 

 Length 5.3-6.9 mm.; width 3.1-3.6 mm.
