the body, the third joint about 3 times as long as the second. Prothorax 

 transverse, barely twice as wide as long, widest at the middle where the sides 

 are prominently rounded, thence moderately convergent and strongly arcuate 

 to the apex, oblique and straight to the base, the latter barely as wide as the 

 apex, broadly, feebly arcuate, deeply sinuate for a short distance near the 

 angles, which are right and posteriorly prominent, extending fully as far 

 backward as the median parts ; disk broadly, evenly and feebly convex, im- 

 pressed near the basal angles, the side margins defined by a thick reflexed 

 bead ; surface smooth and almost sculptureless, but becoming rapidly coarsely 

 and sparsely punctured at the sides, densely and more finely punctured in the 

 impressions ; median line fine and feeble. Elytra oblong, scarcely more than 

 % longer than wide, % wider than the prothorax, slightly wider at apical 

 third than at base, the side margins very narrowly refiexed ; surface moder- 

 ately convex, smooth, with wholly unimpressed equal series of extremely 

 minute punctures, which become slightly more evident and to some extent 

 transverse toward base, the three series on intervals 4, 8 and 12 composed of 

 very fine and widely spaced but quite distinct asperate punctules ; marginal 

 punctures only visible toward base, the submarginal series asperate and dis- 

 tinct throughout. Legs rather slender, black and non-metallic. Length 

 15.7 mm. ; width 7.2 mm. 



Utah. 



The male type has the anterior tarsi quite moderately dilated, 

 the three basal joints pubescent beneath, the pubescent pad of the 

 first joint transversely oval and occupying less than apical third ; 

 the hind trochanters and intermediate tibiae are unmodified. This 

 species is to be placed near peregrinator Guer, (carhonata Lee), 

 but differs greatly in its small size, much smaller head and pro- 

 thorax, structure of the labrum and in many other details. 



C parviceps n. sp. — Eather stout, with relatively very small head and 

 prothorax, deep black and devoid of metallic reflection throughout, the in- 

 teguments rather shining. Sead % as wide as the prothorax, evenly and 

 feebly convex, not rugose but finely, evenly and rather closely punctured, 

 becoming smooth at apex where the lateral impressions are narrow and very 

 deep; labrum dilated and rounded at the sides, transverse at apex, with a 

 broad and very shallow median sinuation, the surface transversely impressed; 

 antennaj short and rather stout, only slightly longer than the head and pro- 

 thorax, the third joint fully 3 times as long as the second. Prothorax moder- 

 ately transverse, about % wider than long, widest at the middle where the 

 sides are obtusely and somewhat bluntly angulate, thence very moderately 

 convergent and broadly, evenly arcuate to the apex, oblique and straight be- 

 hind, becoming slightly sinuate near the base, the latter rather narrower than 

 the apex and somewhat as in the preceding species; disk broadly and very 

 feebly convex, polished, feebly wrinkled, finely and rather sparsely punctate, 

 the punctures becoming coarser and subcoalescent at the sides, more numerous 

 in the impressions near the basal angles; side margins defined by a rather thin,
