three preceding species; hind tarsi much shorter than the tibiae, the 

 first and fifth joints subequal in length. Length (9) 9.8 mm.; 

 width 2.15 mm. New Mexico (Jemez Springs), Woodgate. 



fontinalis n. sp. 



15 Elytra shorter than the prothorax. Body parallel, rufo-piceous, 

 shining, the head black; legs and antenna? dark testaceous; head 

 rounded, as wide as long, the eyes not distinctly prominent, at evi- 

 dently more than their own length from the constriction, the tempora 

 rather strongly converging and broadly arcuate behind them, 

 gradually a little more strongly near the constriction; surface pol- 

 ished, with extremely minute and rather sparse punctulation through- 

 out; two coarse foveae are very near the eyes and two arranged trans- 

 versely behind the eyes but nearer the latter than the constriction; 

 antennae rather long, the outer joints fully as long as wide; prothorax 

 as long as wide, the base more rounded than the sides, the tripunctate 

 seriesdistinct; there isalso onesmall puncturemoreexternal anteriorly 

 and a large one still more lateral at apical third; marginal punctures 

 distinct; scutellum with very few minute punctures; elytra shorter 

 than wide, feebly expanding from the base, where they are narrower, 

 to the apex, where they are fully as wide as, the prothorax; punctures 

 small and well separated, the hairs rather coarse; abdomen with fine 

 sparse punctures, as remote as those of the elytra; hind tarsi with the 

 first three joints decreasing uniformly and rapidly in length. Length 

 (9) 7.4 mm.; width 1.35 mm. Manitoba (Aweme), Criddle. 



curtipennis n. sp. 



Elytra about as long as the prothorax, the head narrower and more 

 oval 1 6 



16 Elytra but slightly expanding from base, where they are fully as wide 

 as the prothorax, to apex, where they are distinctly wider. Colora- 

 tion and polished lustre nearly as in the preceding; head oval, rather 

 longer than wide, the eyes at much more than their own length from 

 the constriction, the tempora gradually converging and subevenly, 

 moderately arcuate to the latter; foveae somewhat as in the pre- 

 ceding; minute punctulation of the median parts invisible under 

 moderate enlargement; antennae shorter and more incrassate than 

 in curtipennis, extending barely beyond the middle of the prothorax, 

 the outer joints not quite as long as wide; prothorax rather small, 

 nearly as long as wide, much rounded at base and nearly as much at 

 the sides, the angles obliterated; punctures nearly as in the preceding; 

 scutellum with more numerous fine punctures; elytra slightly shorter 

 than wide, with rather strong and moderately close-set punctures; 

 abdomen finely, somewhat closely punctate; basal joint of the hind 

 tarsi fully as long as the next two combined. Length (9 ) 6.4 mm.; 

 width 1.25 mm. Montana (Mullan), Wickham. .montanicus n. sp. 



Elytra very rapidly expanding from base, where they are much narrower 

 than the prothorax, to the apex, the sides being notably oblique. . 17 



17 Body notably slender anteriorly, elongate-fusiform, shining, pale 

 brownish-testaceous throughout, the head piceous; legs paler, the 

 antennae darker, ochreo-testaceous; head fully as long as wide, 

 oblong-oval, the eyes at exactly their own length from the con-
