HARPALIN.E 119 



finely, deeply margined, the lateral obliquity always feeble and some- 

 times obsolete, the angles slightly obtuse and evidently rounded; 

 surface almost evenly convex, the reflexed margin very fine and 

 unmodified from apex to base, the latero-basal region a little more 

 feebly convex, impunctate though usually slightly rugulose, the 

 foveae short, feeble, sublinear, impunctate but rather coarsely and 

 feebly rugulose, these rugulee faintly pervading most of the disk and 

 longitudinal along the median parts of the base, the stria very fine; 

 elytra oval, about as wide as the prothorax, rounded behind, parallel, 

 with distinctly arcuate sides, the sinus barely traceable, vestigial, 

 the striae fine, the intervals nearly flat, the puncture small, behind 

 apical third. Length (cf 9 ) 9.7-10.3 mm.; width 3.6-3.9 mm. 

 Colorado (Eldora and Boulder Co.). Thirteen examples. 



furtivus Lee. 



Body smaller and narrower than in furtivus and darker in color, black 

 or with the feeblest piceous tinge, blackish-piceous beneath, polished, 

 the elytra (9 ) slightly alutaceous; head nearly as in the preceding; 

 mandibles rufous, the acute external margin basally and the tip 

 black; prothorax much less transverse, barely two-fifths wider than 

 long, the sides broadly rounded, becoming straighter basally, the 

 apex rather deeply sinuate, with narrowly rounded angles and only 

 slightly narrower than the base, which is rectilinear medially but 

 abruptly strongly and posteriorly oblique at the sides, the angles 

 therefore nearly right, narrowly rounded; surface nearly as in the 

 preceding but without the rugulosity, extremely smooth and polished, 

 with a few traces of longitudinal rugulosity medially near apex and 

 base and with a few feeble punctures near the linear foveolae and 

 near the lateral edges; elytra oblong-oval, nearly one-half longer 

 than wide, rather distinctly wider than the prothorax, especially in 

 the female, the parallel sides broadly arcuate, the sinus vestigial 

 and barely traceable; striae rather fine, feebly impressed (cf), the 

 intervals feebly convex (cf ) or flat (9 ), the puncture before apical 

 fourth. Length (cf 9 ) 8.4-9.5 mm.; width 3.1-3.8 mm. New 

 Mexico (Jemez Springs) and Colorado. Ten examples. 



probatus n. sp. 



Body still smaller, elongate-oval, convex, castaneous above, paler piceo- 

 rufous beneath, highly polished, the elytra ( 9 ) scarqely visibly less 

 so and just perceptibly alutaceous; head as in probatus; prothorax 

 also similar, except that the fine reflexed lateral margins are feebly 

 dilated and punctulate posteriorly, the hind angles similarly nearly 

 right and narrowly but very evidently rounded, the s'urface similarly 

 very feebly flattened very near the hind angles, the foveae linear and 

 still feebler, sometimes slightly punctulate; elytra similar throughout 

 but with feebler striae and flatter intervals; tarsi still more slender; 

 accessory setae of the abdomen similarly extremely few in number. 

 Length (cf 9 ) 7.7-8.0 mm.; width 2.9-3.25 mm. New Mexico 

 (Socorro Co.), Snow. Four examples nitescans n. sp. 



II Mentum tooth distinct and usually more or less acute; basal thoracic 

 angles never very sharply defined, always blunt at their apices as 

 in the preceding section 12
