the elytra or a little longer. Body extremely ventricose, blackish- 

 piceous with rufous legs, polished; head unusually narrow and elon- 

 gate, two-thirds as wide as the prothorax, the eyes notably small and 

 scarcely at all prominent; sulci long, deep and entire; antennae ob- 

 scure rufous; prothorax relatively very small, a third wider than 

 long, the evenly rounded and well reflexed sides becoming slightly 

 sinuate before the acute, sharp and notably prominent basal angles; 

 base and apex equal in width; anterior impression very fine and lin- 

 ear, the posterior feeble, the foveae deep, sublinear, at outer fourth; 

 elytra scarcely a third longer than wide, twice as wide as the pro- 

 thorax, evenly elliptic-oval and very convex; striae very fine, scarcely 

 at all impressed, not clearly punctulate, gradually almost obsolete 

 laterally; dorsal punctures somewhat coarse; sutural stria gradually 

 coarser and deeper apically. Length (of) 44 mm.; width 2.0 mm.

Antennae not as long as the elytra; hind body much less dilated and not 

 quite so convex; head less narrow and not elongate, the eyes more 

 developed 12 



12 Form rather stout, shining, dark rufous, the elytra more clouded; 

 legs rufous; head fully three-fourths as wide as the prothorax, the 

 eyes slightly prominent, moderate in size, the sulci long, deep, entire 

 and strongly arcuate; last palpal joint shorter than the preceding; 

 antennae filiform though not very slender, obscure rufous, but little 

 shorter than the elytra; prothorax nearly one-half wider than long, 

 somewhat wider at base than at apex, the rounded and well reflexed 

 sides becoming briefly but deeply sinuate at the hind angles, which 

 are scarcely more reflexed but acute, very sharp and laterally prom- 

 inent; anterior impression feeble, the posterior coarser and deeper, 

 both subangular; stria very fine, coarser basally; foveae rather large, 

 deep though diffuse; elytra two-fifths longer than wide, two-thirds 

 wider than the prothorax, broadly rounded posteriorly, the humeri 

 and sides almost coarcuately rounded; striae internally rather fine, 

 evidently impressed and finely, obscurely punctulate, gradually ob- 

 solescent laterally, the second as well as fifth with an arcuate apical 

 groove; scutellar stria rather long and deep; dorsal punctures mod- 

 erate. Length (cT) 3.8 mm.; width 1.65 mm. Arizona (locality

 black, the legs rufous; head moderate, two-thirds as wide as the pro- 

 thorax, fully as long as wide, the eyes small, scarcely prominent; 

 sulci deep, entire; last palpal joint very slender, much shorter and 

 narrower than the third; antennae short, filiform, piceo-rufous, clearer 

 basally, scarcely four-fifths as long as the elytra, the joints unusually 

 short; prothorax short, three-fifths wider than long, the rounded 

 sides oblique and straighter posteriad, very feebly sinuate at the 

 hind angles, which are right, not very sharp and not prominent; 

 anterior impression fine, feeble, linear, the posterior coarse and deep; 

 foveae small, deep, slightly beyond lateral fourth; elytra more oblong-
