tured, the sides of constriction with a transverse row of larger punc- 

 tures. Elytra slightly wider and nearly twice as long as thorax, sides 

 parallel to apical third, surface broadly impressed behind the base; striae 

 deep, very coarsely punctured; intervals narrow, strongly convex, third 

 and ninth carinate and confluent near tip, so as to leave a deep fovea 

 between their junction and the posterior callosity, which is well marked. 

 Beneath coarsely, the middle of abdomen more finely, punctate. Length 

 2.73.1 mm. 



Described from Maryland and Virginia. Known also from 

 District of Columbia and Arizona. Occurs on wild grape. 



X. PSEUDOBARIS Lee., 1876. (Gr., "false" + Baris.) 



Usually narrow, subcylindrical, convex species having the club 

 of antenna? entirely pubescent; front coxae widely separated; 

 prosternum deeply and abruptly sulcate along the middle; body 

 above almost glabrous ; pygidinm large, convex and prominent, 

 not inflexed beneath and not at all covered by the elytra; tarsal 

 claws approximate, connate at base.

Oblong-oval, strongly convex. Black, strongly shining. Beak rather 

 slender, moderately curved, as long as thorax, finely punctured above, 

 more coarsely on sides. Thorax short, nearly one-half wider than long, 

 sides nearly parallel from base to middle, then broadly curved and 

 narrowed to apex; disc coarsely, very deeply and rather sparsely punc- 

 tate. Elytra as wide and nearly twice as long as thorax, striae coarse, very
