ClCINDELID/E AND CARABID^E 179 



5 Body only feebly convex, varying unusually in size, shining, blackish- 

 piceous, the sides of the prothorax, flanks of the elytra nubilously, 

 epipleura, median parts of the sterna and the legs paler, testaceous; 

 surface with rather short stiff sparse pale hairs; head rather closely 

 and strongly punctured, except the median parts of the front; 

 antennae moderate, fuscous, paler basally; prothorax a fourth to 

 nearly a third wider than long, nearly as in cribricollis in general 

 character but with the punctures much smaller and very sparse; 

 elytra oblong-oval, slightly widest posteriorly, the sides broadly 

 rounded, about a third longer than wide and two-thirds wider than 

 the prothorax, which is relatively smaller than in cribricollis and less 

 transverse; apices obliquely sinuato-truncate; surface smooth and 

 shining, the striae fine but rather strong, very finely and closely 

 punctulate, the intervals nearly flat, each with a very irregular 

 single series of sparse impressed punctures, which are distinctly 

 larger than those of the striae, the third alone apparently having 

 three or four slightly larger setigerous punctures. Length (cf 9 ) 

 8. 2-1 1. o mm.; width 2.9-3.9 mm. Mexico (Colonia Garcia, Sierra 

 Madre Mts., Chihuahua), C. H. T. Townsend.. . *uniseriata Bates 



Body narrower and rather more convex, paler rufo-piceous in color 

 throughout, the legs and antennae still paler, shining, the elytra 

 rather opaque in the female, alutaceous in the male; hairs short, 

 stiff, fulvous, in single series on the strial intervals; head strongly, 

 sparsely punctured, broadly toward the sides, three-fourths as 

 wide as the prothorax, the antennae two-thirds as long as the body, 

 slender and filiform; prothorax two-fifths wider than long, widest 

 near apical third, formed nearly as in cribricollis, with broadly con- 

 cave and reflexed side margins and feebly prominent obtuse basal 

 angles, the surface however more broadly and evenly convex, not 

 very coarsely but strongly, very sparsely punctate, broadly trans- 

 versely impressed and more coarsely, closely and subrugosely 

 punctured near the base, the median stria fine but rather impressed, 

 not entire; elytra two-fifths longer than wide, about one-half wider 

 than the prothorax, slightly broadened posteriorly, the apices 

 broadly, evenly arcuate, becoming straight or very faintly sinuate 

 only near the broadly rounded outer angles; striae excessively fine 

 and faint, not at all impressed and extremely finely, not at all closely 

 punctulate, the flat intervals each with a single very.irregular series 

 of very fine and feeble punctures, not differing much from those of 

 the striae, the third, fifth and seventh with a series of slightly larger 

 setigerous punctures, about four in number on each; male with a 

 small rounded impression at each side of the middle at the apex of 

 the last ventral segment. Length (cf 9 ) 8.2-9.0 mm.; width 3.0- 

 3.3 mm. Utah (Marysvale), H. F. Wickham.. . .evanescens n. sp. 



6 Elytra broadly, obliquely arcuate at apex, not at all sinuate and with 

 very broadly rounded outer angles; intervals three, five and seven 

 each with about four setigerous punctures; pronotum more broadly 

 and evenly convex throughout the width 7 



Elytra feebly obliquely sinuato-truncate at apex, the third interval alone
