FOUR OCHOD^US NEW TO THE UNITED STATES.

Working over some neglected material, I found, to my surprise, that the 



specimens of Ochodceus collected by me last year in Arizona are 



separable into three distinct species, none of which agree with the 



descriptions of the North American species. A few years ago my brother 

 sent me from California, with some other material, two specimens of what 

 I take to be an Ochodceus. Unfortunately, 1 misplaced one of the 

 specimens, and not wishing to dissect the single remaining one, I leave 

 this species in this genus for the present, till more material is available. 



OchodiEus p/iviifrons, new species. — Male : Ferruginous-brown. 

 Head sub-convex, granulate ; clypeus short, transverse, broadly arcuate- 

 truncate in front, feebly sinuate at sides, frontal margin single, clypeal 

 suture feebly impressed, but visible ; labrum deeply arcuate-emarginate. 

 Prothorax moderately densely granulate, and with very short stiff semi- 

 erect hairs, median impression obsolete. Elytra punctate-striate, intervals 

 feebly convex, not densely punctate, punctures irregularly placed, each 

 bearing a coarse, short hair, these are slightly longer at apex and sides 

 than on the disk ; sutural angle obtuse. Propygidium with a longitudinal, 

 nearly parallel, median groove, apical margin strongly beaded. IMentum 

 slightly longer than broad, deeply, longitudinally concave at middle. 

 Prosternum arcuate-truncate in front. A^nterior tibiae tridentate, the upper 

 tooth very small, and nearer the base than the second tooth. Posterior 

 femora with a triangular tooth at apex ; posterior tibiae, inside at about 

 apical fourth obtusely toothed or rather angulate ; first joint of hind tarsi 

 long, elongate. Body beneath moderately clothed with long hairs. 



Female : Differs only from the male by having the hind tibiae simple, 

 the hind femora at apex with a smaller and more obtuse tooth and the 

 clypeus slightly broader. 



Length. 5 mm. 



Huachuca Mts., Arizona. July and August. 



This species, by the form of the male hind tibiae, is very distinct from 

 the described species, and is best placed after Ulkei in Dr. Horn's table.* 

 The size, as usual, is variable ; some are larger than the above measurement,
