140 MEMOIRS ON THE COLEOPTERA 



sides, three-fourths longer than wide, the apical lobe large, moderately 

 abrupt; surface convex, less so medially, even throughout though 

 with unusually coarse deep and close-set punctures, partially con- 

 fluent here and there, the side margins not much reflexed, abruptly 

 ending at apical fifth; under surface deep black and shining; epi- 

 pleura coarsely, loosely punctate, the abdomen smooth, with fine 

 anastomosing creases. Length (9) 27.0 mm.; width 12.4 mm. 

 New Mexico, Schaupp cribratus n. sp. 



Pronotum with two discal impressions; punctures of the head always 

 separated 14 



14 Form (cf) elongate-pyriform, very moderately convex, piceous- 

 black, the elytra dark to bright rufous; head moderately impressed, 

 rather coarsely, deeply, irregularly punctate and with irregular 

 impunctate patches; prothorax relatively small, two-fifths wider 

 than long, two-thirds as wide as the elytra, almost as strongly nar- 

 rowed basally as apically, the sides strongly arcuate, surface alu- 

 taceous, with moderately coarse, irregularly somewhat close, deep 

 punctures and with a rather elongate feeble impression at each side 

 at lateral fourth behind the middle, causing the median convexity 

 to be strongest between them, the sides feebly reflexed, transversely 

 rugose, the basal impression strong; elytra two-thirds to three- 

 fourths longer than wide, even, seldom with traces of raised lines, 

 coarsely but not very deeply punctate, the punctures generally well 

 separated but more or less confluent laterally, widest behind the 

 middle, the sides basally converging and broadly arcuate, the margins 

 moderately to feebly reflexed, ending at apical fifth or sixth; under 

 surface shining and darker as a rule, the legs rather stouter than 

 usual and only moderate in length. Length 24.0-26.0 mm.; width 

 11.5-11.8 mm. New Mexico (locality and collector unrecorded). 



subcruentus n. sp. 



Form (cf ) more oblong and parallel, more convex, shining throughout, 

 blackish-piceous, the elytra bright red; head nearly similar; pro- 

 thorax very much larger, nearly as wide as the elytra, one-half 

 wider than long, more broadly and less strongly convex, the rather 

 coarse punctures very irregularly disposed, sometimes leaving large 

 vacant areas, having a small rounded feeble impression at each side 

 rather beyond lateral fourth and slightly behind the middle; sides 

 evenly, moderately arcuate, rather strongly reflexed, densely, 

 transversely vermiculato-rugose, the basal impression distinct and 

 on the basal declivity as usual; elytra suboval, three-fourths longer 

 than wide, evenly convex, but faintly inflated posteriorly, the 

 sides broadly arcuate; surface nearly as in the preceding but with 

 the punctures deeper, the side margins nearly similar; legs moder- 

 ate, somewhat more slender. Length 24.0 mm.; width n.o mm. 

 Arizona (locality unknown) semirufus n. sp. 



Form (cT ) unusually narrow, elongate and less convex, alutaceous, deep 

 black throughout above and beneath; head deeply impressed, the 

 transverse impression interrupted medially and with the impression 

 at the middle of the vertex also distinct, the punctures moderately
