punctate, the sutural interval alone with confused punctures; 

 abdomen medially and femora minutely, sparsely punctured 

 throughout. Length 7.7 mm.; width 3.0 mm. Arizona. 



parvuliceps n. sp, 



Body more broadly oblong and still less convex, more depressed than 

 in almost any other species, dark rufo-piceous, the legs and an- 

 tenniE paler, polished; head moderate, but little more than half 

 as wide as the prothorax, the sides much less converging than 

 usual, arcuate, becoming parallel toward the eyes, the apex trun- 

 cate, the punctures only moderately coarse, dense, confluent 

 toward the eyes, the occipital spot small, sometimes almost want- 

 ing ; prothorax but very slightly less than twice as wide as long, 

 the sides moderately arcuate, more converging apically, the basal 

 angles nearly right, not at all prominent, the punctures rather 

 small but deep, moderately separated, becoming very gradually 

 but moderately coarse and dense and forming long rugje laterally ; 

 scutellum rather well developed, transverse, sparsely punctured; 

 elytra as in parvuliceps., more than three times as long as the 

 prothorax but not wider, the punctures smaller throughout, espe- 

 cially toward the sides and more irregularly disposed suturally ; 

 abdomen finely, sparsely and evenly punctured medially through 

 the first three segments. Length 6.9-7.2 mm. ; width 3.1S-3.22 

 mm. Arizona rufopiceum n. sp. 



Body relatively shorter, stouter, more oblong and rather more convex, 

 shining, piceous-black, the under surface dark, the legs and an- 

 tennae pale, rufous ; head well developed, almost three-fifths as 

 wide as the prothorax, coarsely, not very densely punctate ; pro- 

 thorax twice as wide as long, a little less in the male, the sides 

 evenly and vmusually strongly rounded, the basal angles very 

 obtuse, not rounded or prominent, the punctures not coarse but 

 strong, well separated, becoming rapidly very coarse, dense and 

 subconfluent in almost lateral fourth ; scutellum well developed, 

 transverse, punctured except apically; elytra not quite one-half 

 longer than wide, about three times as long as the prothorax 

 and scarcely perceptibly wider, very rapidly and obtusely ogival 

 at apex, the punctures rather close-set in somewhat irregular 

 series, moderately small and strong suturally, coarse and muri- 

 cate laterally, the interstitial punctures sparse and broadly con- 

 fused suturally, irregularly serial laterally, the subsutural series 

 scarcely at all impressed; abdomen not very coarsely but un- 

 usually strongly, conspicuously, moderately loosely and evenly 

 punctured medially, somewhat more coarsely on the basal seg- 

 ment; femora minutely, sparsely punctured. Length 7'2~7*75 

 mm. ; width 3.2S-3.35 mm. Texas (El Paso) ...saginatum n. sp. 



16 — Form parallel, moderately slender and not very convex, polished, 

 black with feeble piceous tinge, the legs and antennje rufous ;
