302 CURCULIONID^. 



PACHYBABIS n. g. 



[LeConte. 



A single glabrous species of very stout form and coarse sculpture repre- 

 sents this genus. It has the characters of Onychobaris except that the 

 elytra are conjointly rounded behind, so as to cover the pygidium, and the 

 fifth ventral, though very transverse is broadly rounded behind. The 

 beak is slender, longer than the head and prothorax, moderately curved, 

 and striato-punctate, a character not seen in any other of our species. The 

 antennae are stout, first joint of funicle elongate, second not longer than 

 the third, remaining joint gradually stouter, merging into the club, which 

 is elongate-oval, annulated and entirely pubescent. Prothorax broader than 

 long, strongly but gradually narrowed from the base, rounded on the 

 sides, scarcely constricted in front. Elytra very little wider than prothorax 

 at base, humeral callus not prominent, gradually narrowed behind, con- 

 jointly rounded at tip. Prosternum rather broad between the coxae 

 longitudinally slightly concave in front, with two short impressions con- 

 nected at their anterior end. Legs rather stout, thighs unarmed, tibiae 

 rather short, scarcely mucronate, marked with two fine lines and inter- 

 vening ridge on outer surface; third joint of tarsi broadly dilated, last joint 

 moderate, claws rather large, divergent. 



1. P. porosus, n. sp. 



Broadly oval, black, moderately shining. Beak slender, punctured in 

 rows, sides striate; head punctured, frontal constriction obsolete. Pro- 

 thorax strongly punctured, scutellar lobe large, emarginate. Elylra very 

 deeply striate, strife punctured, interspaces flat, each with a row of large 

 approximate punctures, bearing very short whitish hairs. Beneath coarsely 

 punctured. Length 3.7 mm. ; .15 inch.

STETHOBARIS n. g. 



The single species of this genus is rather broadly oval, though less so 

 than Pachybaris. The beak is as long as the head and prothorax, rather 

 stout, curved finely, punctulate; head distinctly punctured, convex, frontal 

 constriction strong, eyes narrowly separated beneath; antennas stout, first 

 joint of funicle elongate, second not longer than third, the following 

 gradually a little broader; club large, elongate oval, annulated, entirely 

 pubescent. Prothorax broader than long, convex, rapidly narrowed in 

 front and rounded on the sides, very strongly and tubularly constricted 

 near the tip. Elytra gradually wider than the prothorax at base, then 

 rounded on the sides, and conjointly rounded at tip, covering entirely the 

 pygidium. Front coxae rather widely separated, prosternum with a deep 

 smooth sharply defined groove. Legs longer, rather stout, thighs not 

 toothed, tibiae faintly grooved, feebly armed at tip; third joint of tarsi 

 broadly dilated, last joint small; claws very small, approximate but not 

 connate.
