pale, rather shorter than in either of the preceding; prothorax two- 

 fifths to nearly one-half wider than long, throughout nearly as in 

 arizonensis but with the coarse punctures more numerous and less 

 irregularly disposed; elytra almost as in laticollis throughout and 

 evidently shining in both sexes, the striae still slightly finer and 

 similarly minutely punctate, the intervals flat or virtually so, with 

 fine and evidently less numerous confused punctures, each bearing 

 a much longer stiff hair, those of the fourth and sixth intervals 

 sometimes displaying a tendency to arrangement in a single irregular 

 line; fifth ventral in the male having a small and shallow but very 

 distinct apical sinus, which is perfectly constant in the four males 

 at hand, the surface apically sometimes with a very broadly obtuse 

 faint raised axial line. Length (cf 9 ) 9.8-10.5 mm.; width 3.5-3.75 

 mm. Arizona (Benson), Dunn and also New Mexico. 



zuniana n. sp. 



9 Seventh elytral stria impressed and similar to the others or but slightly 

 feebler. Body not stout, very moderately convex, rufo-piceous in 

 color, the side margins, under surface, except the blackish margins 

 and sides of the abdominal segments, and the legs, still paler; head 

 well developed, the neck wide, the eyes only moderate in size or 

 prominence; punctures very coarse, deep, rather close-set, largely 

 wanting antero-medially ; antenna* rather long and slender; prothorax 

 two-fifths wider than long, the sides very evenly rounded anteriorly, 

 converging, becoming gradually feebly and broadly sinuate poste- 

 riorly to the obtuse though slightly prominent angles; surface nearly 

 even, coarsely, rather closely, somewhat unevenly punctate, the 

 sides very broadly concave, strongly reflexed and diaphanous as 

 usual, the general form as in cribricollis; elytra a little longer than 

 in that species but otherwise nearly similar in form, the striae notably 

 coarser and deeper, especially in the female, with the punctures 

 everywhere more close-set and confined to the limits of the striae, 

 the intervals very feebly convex and with numerous punctures, 

 irregularly but not densely disposed and rather smaller than those of 

 the striae; fifth ventral (cf) almost evenly rounded behind, the surface 

 longitudinally convex and with a very short faint raised axial line 

 at tip. Length (cf 9 ) 9-5-9-8 mm.; width 3.4-3.5 mm. New 

 Mexico acomana n. sp. 



Seventh stria unimpressed, very feeble and sometimes almost obliter-

10 Sides of the pronotum only moderately broadly but rather more 

 abruptly reflexed, the pronotal punctures slightly less coarse. Color 

 blackish-piceous throughout above, except, as usual, at the side 

 margins, the under surface varying from almost entirely black to 

 almost completely pale; head rather short, with only moderately 

 wide neck and prominent eyes, the punctures coarse, larger than those 

 of the pronotum and rather close-set: antennae testaceous, rather 

 slender; prothorax in outline nearly as in cribricollis but more evenly 

 convex from side to side and with evidently less coarse though equally 

 close-set punctures; elytra narrower, more than two-fifths longer than 

 wide, three-fifths wider than the prothorax, the striae fine (cf 1 ) but
