208 MEMOIRS ON THE COLEOPTERA 



entire, evenly arcuate on the front; prothorax almost twice as wide 

 as the median length, with evenly arcuate converging sides and 

 sharp apical angles, the surface smooth, the lateral striae moderate, 

 the outer fully attaining the base, the inner slightly abbreviated, 

 the intermediate surface smooth, except that there is some minute 

 and very feeble punctulation and, anteriorly, one or two of the rugulse 

 characterizing the two preceding species; elytra fully a third wider 

 than long, the sides evenly arcuate, distinctly converging posteriorly, 

 each with three entire striae, the fourth represented by a very short 

 basal line, the subhumeral by a very short dash before the middle, 

 oblique humeral fine but evident; red color extending to the sides 

 but not quite to apex, the black plaga but slightly wider posteriorly, 

 wider than long; propygidium with rather large but very shallow, 

 remotely scattered punctures; pygidium convex, with small and 

 sparse punctures, becoming rather coarse only very near the base; 

 mesosternal sinus very deep. Length 6.3 mm.; width 4.4 mm. 

 Utah (southwestern) semiruber Csy. 



Sutural stria distinct though never entire 6 



6 Punctures of the propygidium coarse and dense laterally, mingled 

 everywhere with distinct small punctures; body more broadly oval, 

 the tibiae more dilated distally, the two lateral striae of the pronotum 

 very approximate at base. Color black, the abdomen rufescent, 

 the legs not at all pallescent; integuments highly polished; head with 

 minute remote punctulation, the ambient stria entire, evenly curved; 

 prothorax only three-fifths wider than long, strongly convex, the 

 sides rather strongly converging and very feebly arcuate from the 

 base, more rounding apically; surface minutely, remotely punctulate 

 laterally, the striae coarse and deep; elytra nearly a third wider than 

 long, the arcuate sides moderately converging, the subbasal inflation 

 feeble; three entire striae very coarse, becoming finer apically, the 

 fourth represented by short subbasal and subapical dashes, the sutural 

 sharply defined from basal third nearly to the apex, the humeral a 

 succession of short incisures from basal third nearly to tip, the sub- 

 humeral a short stria near basal third, the oblique humeral deep and 

 very distinct; propygidial punctures not quite so coarse or close 

 medially, those of the pygidium notably coarse, deep and close-set, less 

 coarse but not sparser apically; prosternal lobe narrowly parabolic; 

 mesosternum rather deeply sinuate; teeth of the anterior tibiae 

 each with an abruptly smooth rounded extension, appearing like a 

 short broad eroded spine. Length 7.0 mm.; width 4.85 mm. New 

 Mexico (Deming), Wickham subcruentus n. sp. 



Punctures of the propygidium always sparse and never so coarse, the 

 intermingled punctulation never more than extremely minute; 

 body less broadly oval; lateral striae of the pronotum remaining 

 widely separated throughout their length 7 



7 Legs black, with the femora red, blackish at base and apex as in 

 arcuatus. Body short, subquadrate-oval, convex, shining, black, 

 the elytral red areas large, extending to the sides but not quite to 

 apex, the medio-basal black spot not extending to the middle and 

 wider than long; head smooth, the ambient line transverse on the
