but rather strongly sinuate at tip. Length (cf ) 17.2 mm.; width 6.7 

 mm. New Mexico (Luna) cylindricollis n. sp. 



5 Punctures of the basal part of the inflexed elytral flanks large, rather 

 close-set and very strongly graniferous; body very elongate, deep 

 black, shining, entire front finely and rather closely but unevenly 

 punctate; antennae less than three-fifths as long as the body, the 

 annulus of the fourth joint very sharply defined, not attaining the 

 base; prothorax nearly as in cylindricollis, except that there are 

 very few fine, irregularly dispersed punctures, these a little larger 

 and somewhat more numerous basally but of the same character as 

 the others; elytra rather more than twice as long as wide, smooth, 

 oval, more pointed behind, convex but with the upper limit of the 

 flanks very sharply defined nearly to the middle; surface smooth 

 but with faint vestiges of rapidly wavy longitudinal lines laterally, 

 the punctures fine and sparse, not extending to the middle ; last dorsal 

 red; fifth ventral (cf ) rufescent at tip, broadly, distinctly sinuate; 

 femora (cf ) unusually rapidly and very strongly clavate apically. 

 Length (cf) 23.0 mm.; width 9.0 mm. Arizona (Douglas), Snow. 



microsticta n. sp. 



Punctures of the basal parts of the inflexed elytral flanks coarse but 

 sparse and not graniferous 6 



6 Elytra very moderately convex, widest distinctly before the middle, 

 thence gradually narrowing posteriorly, the sides arcuate throughout; 

 body stout, piceous-black, rather large, shining; front with fine 

 scattered punctures laterally; antennae (cf ) half as long as the body; 

 prothorax larger than usual, slightly wider than long, the sides 

 parallel and straight, converging slightly near apex and base; 

 punctures very fine and extremely sparse, larger and more numerous 

 near the base, perforate; elytra abruptly declivous along a prominent 

 though blunt line to rather behind the middle, two-thirds longer 

 than wide, smooth, with faint longitudinal inequalities, the punctures 

 small and scattered in basal two-fifths; femora (cf ) very much in- 

 flated, the fifth ventral rufescent, broadly, distinctly sinuate, with 

 a broad and flat marginal bead; last dorsal red. Length (cf ) 

 25.0 mm.; width 10.8 mm. Western Texas appressa Lee. 



Elytra strongly convex, the delimiting line of the flanks much less promi- 

 nent, broadly rounded in transverse section as a rule, almost evenly 

 elliptic in outline and widest at about the middle; size smaller and 

 narrower; elytra with shallow and wavy, approximate furrows, the 

 body black to piceous-black, the last dorsal red throughout; lustre 

 subopaque or slightly shining; front with a very few fine punctures 

 near the sides; antennae two-thirds as long as the body; prothorax 

 nearly as long as wide, much smaller than in appressa, the sides 

 undulated, subconstricted near the base; punctures very fine and 

 extremely few in number even near the base, where they are but 

 slightly less minute; elytra twice as long as wide, the punctures fine 

 and very sparse, only present in basal fourth, the flanks not less 

 opaque and with the moderately large punctures sparse even 

 basally, the line of flexure broadly convex ( 9 ), more sharply defined 

 (cf ) ; femora much inflated distally (cf ) and rather stouter than usual
