HARPALIN^E 249 



smoother, without the longitudinal rugulae generally evident in 

 congener, the basal foveae feebler; elytra much narrower, rather more 

 than one-half longer than wide and only about a third wider than 

 the prothorax, similarly striate and with moderately convex intervals. 

 Length (cf) 3.75-4.0 mm.; width 1.2-1.25 mm. California (near 

 San Diego), Dunn. The hind tarsi in one example are much shorter 

 than in the other, possibly from muscular contraction. 



purgatus n. sp. 



Body larger, broader and more convex, very shining, pale testaceous, the 

 elytra with a feeble subposterior blackish cloud, divided by the 

 suture, the under surface of the hind body pale piceo-rufous, the 

 legs paler; head as pale as the prothorax and three-fourths as wide, 

 with very prominent eyes; antennae slender, dusky-testaceous, not 

 one-half as long as the body; prothorax rather short, fully a third 

 wider than long, of the usual anteriorly inflated form, the hind angles 

 obtuse, with their apices sharply defined but not minutely prominent 

 as a rule; base distinctly narrower than the apex; surface smooth, 

 the foveae moderate, feebly impressed and punctured as usual; elytra 

 not quite one-half longer than wide, fully one-half wider than the 

 prothorax, the striae deep and sulciform and with convex intervals 

 suturally, feebler laterally and apically; hind tarsi slender, only 

 moderate in length. Length (cf 9 ) 3.8-4.8 mm.; width 1.35-1.9 

 mm. Arizona (Tugson) to Texas (Austin and Waco), and north- 

 ward to Nevada (Reno) and California (Truckee). Abundant.

nubifer Lee. 



Body much smaller than in either of the preceding 13 



13 Form oblong-oval, moderately convex, pale rufo- testaceous above and 

 beneath, excepting a small cloud on each elytron posteriorly; head 

 nearly four-fifths as wide as the prothorax, the eyes very prominent, 

 separated by three and one-half times their own width; antennae 

 dusky testaceous, paler basally, rather short; prothorax about a 

 fourth wider than long, the sides rounded anteriorly, converging, 

 becoming sensibly sinuate for some distance before the basal angles, 

 which are acutely prominent and more nearly right than usual; 

 surface broadly but scarcely visibly impressed and closely punctured 

 throughout, though variably so, latero-basally ; base very slightly 

 narrower than the apex; elytra rather less than one-half longer than 

 wide, two-fifths wider than the prothorax, broadly and circularly 

 rounded behind, finely striate and with very feebly convex intervals 

 throughout, the discal puncture at three-fifths. Length (9) 3.2 

 mm.; width 1.15-1.2 mm. Colorado River at Yuma, California and 

 Arizona. [Bradycellus rival-is Lee.] rivalis Lee. 



Form and coloration nearly similar throughout; head similarly large and 

 well developed and with very prominent eyes that are separated by 

 barely more than three times their own width; antennae fuscous, 

 paler basally, longer than in rivalis, being about half as long as the 

 body; prothorax similar but relatively shorter, a third wider than 

 long, the converging sides posteriorly straight to the very obtuse
