coarsely punctured ; prothorax ((^) large, not quite one-half wider 

 than long, the apex three-fourths as wide as the base, the angles 

 much prolonged anteriorly but scarcely at all everted, the sides 

 evenly and distinctly arcuate, the basal angles acute and everted, 

 the surface almost even, rather coarsely, closely and subevenly 

 punctured throughout, without evident impunctate line; prothorax 

 (Q) trapezoidal, smaller, with nearly straight sides which are very 

 widely thickened except toward apex, the sculpture and ridges 

 nearly as in acutus ; elytra conspicuously and coarsely rugose, 

 rather coarsely, closeh' punctured, densely but less deeply toward 

 the sides, the broad impressed lines feeble; abdomen shining, 

 minutely, not very closely punctulate medially. Length 11.S-12.8 

 mm.; width 5.7-6.0 mm. Texas subrudis n. sp. 



Form much narrower than in either of the preceding species, elongate- 

 oval, strongly convex, rather shining, brilliant bronze in lustre, the 

 pubescence short, cinereous and not dense ; head closely, rather 

 coarsely punctured, the epistoma finely but not very densely, broadly 

 angulate ; prothorax {(^) two-fifths wider than long, the apex three- 

 fourths as wide as the base, with the angles narrowly prolonged, 

 prominent and strongly everted, the sides rather strongly arcuate, 

 becoming feebly sinuate toward the basal angles, which are acute 

 and slightly prominent, the surface rather finely and sparsely punc- 

 tate, more coarsely and closely so laterally, nearly even, with a 

 well marked, obsoletely impressed impunctate line ; elytra oblong- 

 oval, parallel and feebly arcuate at the sides, strongly rounded at 

 base to the thoracic angles, the surface somewhat coarsely, irregu- 

 larly plicato-rugose, finely, strongly, not very closely punctate sutur- 

 ally, less finel}^, closely and rugosely so laterally, the impressed 

 lines wide and feeble but evident ; abdomen minutelv rugose and 

 strongly, rather closely punctate medially. Length 11.3 mm.;

 or viridi-aeneous, the pubescence short and rather sparse ; head 

 rather finely, moderately closely punctured, the epistomal lobe 

 large, angulate; prothorax {(^) about a third wider than long, 

 of the same form as in the preceding species, the sides feebly 

 arcuate, the apical angles very acute and sometimes feebly everted, 

 the basal acute and prominent, the surface sometimes with a feeble 

 narrow tumorosit}' at each side of the middle anteriorlv, finely 

 but strongly, rather closelv punctate, more coarsely, rather densely 

 so laterally ; prothorax ( 9 ) of the same general form and sculp- 

 ture as in acutus', elytra oblong-oval, with feebly arcuate sides, 

 strongly rounded at base to the thoracic angles, at the middle 

 much wider than the prothorax, the impressed lines wide and 

 strong, the punctures minute and sparse suturally, still fine but 

 close-set, with the surface less sliining latcrallv ; abdomen finely, 

 feebly rugulose and finelv, rather sparselv punctate medially.
