impressed between the eyes ; beak slightly longer than the head and 

 thorax, and feebly curved, tricarinate, at apex rather closely punctate, 

 punctures elongate at sides, and larger than at middle ; antennae inserted 

 at about apical fourth. Thorax slightly broader than long ; sides nearly 

 straight to slightly before middle, then narrowing to apex, where the 

 impression is feeble ; surface with large closely-placed punctures, which 

 are confluent at apex, not carinate, very sparsely clothed with short, 

 forwardly-inclining, decumbent yellowish hairs. Elytra with rows of large 

 punctures, alternate intervals feebly convex ; surface with recumbent dark 

 set?e, and very sparsely clothed with white and ochreous hairs, the latter 

 forming an indistinct post-median fascia. Body beneath sparsely 

 pubescent; mesosternum flat, truncate in front, abdomen coarsely punc- 

 tate, punctures of last segment smaller. Legs slightly annulated, femora 

 with two moderate teeth ; claws finely toothed. Length, 4 mm. 



Huachuca Mts., Arizona. 



There is no sinuation at the sides of the elytra below the humeri, and 

 the sides of elytra are more parallel to slightly behind middle than in any 

 other species of Division I-A of Leconte, where this species has to be 

 placed. This group contains those species which have the claws divergent, 

 toothed, not cleft, prothorax not sulcate, femora bidentate, and elytral 

 costae interrupted. The three specie described above all belong to this 

 group, and to facilitate their identification the following table is presented. 

 Our anaglypticus, which occurs in Mexico also, has two crests in front of 

 thorax, and the surface between these impressed, but specimens occur 

 without crest and impression. A few of the species in the following table 

 are not represented in the material before me, and the characters employed 

 had to be taken from the descriptions. 



1. Costae of elytra abruptly interrupted 2 



Costa of elytra feebly interrupted ^ 



2. Thorax strongly tuberculate tuberculicollis, n. sp 



Thorax without tubercles 3 



3. Post-median elytral fascia uniformly white or pale yellow 4 



Post-median elytral fascia white and yellow ; the two post-mediar 



elytral crests near suture much larger than the 



others ?id?iup/iar, Hbst. 



4. The two post-median elytral crests near suture large, more elevated 



than the others ; elytra with a pale-yellow fascia 



behind middle jughmdis, Lee.
