others smaller ; in the larger specimens the angulation on inner side of hind 



tibiae is more prominent than in the smaller specimens. 



Ochodceus ifiarfuatus, new species — Brownish-ferruginous. Head 



and clypeus coarsely rugose, front with a short transverse carina, which is 



emarginate at middle ; behind the carina the surface is less coarsely 



sculptured than before ; clypeus hemihexagonal, margin single, clypeal 

 suture distinct, but feebly impressed. Labrum broadly, not deeply 

 emarginate. Prothorax relatively coarsely and densely granulate and with 

 very short recumbent hairs. Elytra striate-punctate, intervals feebly 

 convex, moderately coarsely punctured, punctures irregular, and each 

 bearing a short setiform erect hair ; sutural angle sinuate. Apical margin 

 of propygidium narrowly interrupted at middle with a small acute tubercle 

 on each side. Mentum longer than broad, deeply longitudinally impressed 

 from base to apex, the latter broadly emarginate. Prosternum arcuate in 

 front. Posterior femora and tibiae simple. Body beneath sparsely 

 clothed with moderately long hairs. 



Length, 7 mm. 

 . Huachuca Mts., Arizona. July and August. 



The head behind and before the emarginate frontal carina is 

 shallowly impressed. The two sexes do not seem to differ, except that 

 the head in what I consider the female is less distinctly carinate 

 and hardly at all impressed before and behind the carina; otherwise there 

 is scarcely any difference in the large series before me, except in size. 

 The measurement is taken from one of the larger specimens. This species 

 has to be placed v^'xih. penifisular is, near biarjnahis, in Dr. Horn's table, 

 from both distinguished principally by the emarginate frontal carina of the 

 head. From the Mexican luridus, which has a similar armature of the 

 head, it differs by the coarsely-sculptured head, the irregular punctuation 

 of the elytral intervals and the larger upper tooth of the anterior tibiae, 

 which is situated nearer the second tooth than the base. 



Ochodceus prcesidii, Bates, Biol. Cent. Am. col. Vol. H., pt. 2, 106. — 

 Male : Ferruginous. Head coarsely cribrateiy punctate ; front with a 

 feebly-indicated carina ; clypeus very narrow, with a double margin, the 

 posterior margin more elevated and slightly more prominent at middle and 

 at sides. Labrum feebly emarginate in front. Prothorax densely 

 asperately punctate, with short semi-erect hairs and a posteriorly deeply- 

 impressed dorsal line. Elytra punctate-striate, intervals feebly convex.
