Length (cf 9 ) 6.3-6.5 mm.; width 2.8 mm. North Carolina (South- 

 ern Pines), Manee. Three examples corvina n. sp. 



1 6 Body larger, the elytra much wider than the prothorax; anterior 

 tarsi very feebly dilated in the male. Form oblong-suboval, mod- 

 erately convex, highly polished throughout above in the male, dark 

 castaneous; under surface black, the abdomen and middle of the 

 prosternum rufescent; legs dark rufous; head large, two-thirds as 

 wide as the prothorax, with large and somewhat prominent eyes, 

 the strioles deep, linear and oblique; antennae ferruginous, long, 

 extending well behind the thoracic base; prothorax relatively small, 

 rather more than one-half wider than long, the sides feebly converg- 

 ing, feebly and subevenly arcuate and finely reflexed from near the 

 base to the apex, curving inward slightly at base, the angles more 

 than right but sharp; apex three-fourths as wide as the base, sinuato- 

 truncate, with broadly obtuse angles; basal impression distinct and 

 with rather coarse punctures throughout the width except medially, 

 the anterior obsolescent; stria very fine, abbreviated; inner fovea 

 large, broad, just visibly impressed, the outer smaller and deeper; 

 elytra two-fifths longer than wide, three times as long as the pro- 

 thorax and nearly a fourth wider, the base distinctly wider than the 

 thoracic base; sides broadly, feebly arcuate, obtusely rounded in 

 apical third; striae very finely, slightly punctulate, the scutellar long, 

 longitudinal and free; lateral series moderately interrupted; inter- 

 vals flat; central prosternal fovea of the male very small, oval, im- 

 pressed; abdomen with many small punctures latero-basally, the 

 tip with two pairs of punctures. Length (cf) 8.0 mm.; width 3.65 

 mm. Arizona amplipennis n. sp. 



Body smaller, much narrower, the elytra not distinctly wider than the 

 prothorax. Form elongate-oval, convex, polished, pale castaneous; 

 under surface and legs rufo-flavate; head shorter than wide, three- 

 fifths as wide as the prothorax, with moderate but prominent eyes 

 and coarse deep converging strioles; antennae ferruginous, notably 

 short, not longer than the thoracic width (cf ), still shorter (9 ); pro- 

 thorax three-fifths wider than long, the sides broadly arcuate and 

 feebly converging from the base, slightly more arcuate very gradu- 

 ally toward apex, finely reflexed ; apex two-thirds as wide as the base 

 or more, feebly sinuate, the angles broadly blunt; impressions very 

 faint; foveal region with a few widely scattered punctures; inner 

 fovea broadly impressed and partially sublinear, the outer deeper, 

 rounded, not quite basal; elytra two-fifths to one-half longer than 

 wide, gradually rounded, in apical two-fifths, with the sides feebly 

 arcuate, the thoracic and elytral bases equal; striae moderately fine, 

 subimpressed suturally, impunctate, the scutellar short, oblique, free; 

 lateral series distinctly interrupted; intervals wide, flat or nearly 

 so; central fovea of the prosternum (cf ) very small, impressed, 

 narrowly oval; abdominal apex with two punctures at each side in 

 both sexes. Length (cf 9 ) 6.0-6.8 mm.; width 2.5-2.9 mm. New 

 York (Jamaica, Long Island), Fred. M. Schott schotti n. sp. 



Body nearly as in the preceding but shorter, the elytra not distinctly 

 wider than the prothorax. Darker castaneous, very feebly metallic,
