STAPH YLINID.E. 77 



OXYTELUS Gravenhorst. 



A cosmopolitan g-euus, with-numeroiis species, of which North America 

 has its fair share. It has been recognized in the early Tertiaries of New- 

 South Wales, and in amber, and four species have been described from 

 Alsatia. Oeningen, and Utah. 



OxYTELUS PRISTINUS. 



Oxytelm prlsUnits Scudd., Bull. U. S. Geol. Geogr. Surv. Terr., II, 79 (1876); Tert. 

 Ins. N. A., 503-50-i, pi. 5, figs. 118-120 (1890). 



Wliite River, Utah. 



GEODROMICUS Redtenbacher. 



A north temperate genus with a moderate nvimber of species, of which 

 North America possesses only four. It has been found fossil only in 

 America, in the older Tertiaries of Colorado, and in the Pleistocene of 

 Canada. 



Geodromicus abditus sp. nov. 



PI. IX, fig. 3. 



Unfortunately the single specimen on which this species is founded 

 lacks the head, but as the form and surface structure of the other parts is 

 somewhat peculiar, it is with little doubt that we place it here. The thorax 

 is scarcely broader than long, the front and hind margin truncate, the sides 

 strongly convex and slightly angulate just in advance of the middle, the 

 hind margin therefore a little narrower than the front margin, the angles 

 scarcely rounded; there is a shglit median impressed line, and the whole 

 surface is very dehcately granulated, with scattered short delicate hairs- 

 The elytra are half as broad again as the thorax, but narrow toward the 

 base; they are nearly twice as long as the thorax, and they are together 

 angularly emarginate at apex, and delicately margined laterally; the surface 

 structure is the same as that of the thorax, only the granulations are a trifle 

 coarser. The abdomen is scarcely so long as the thorax and elytra together, 

 long ovoid, naiTower at base than the elytra, beyond equal to it in breadth, 

 roundly pointed at apex; the surface is vaguely granulated and very sparsely 

 and briefly pilose. The whole body is piceous.
