Tribe XVIII. BARINI. 



To this, one of the most important tribes of the Curculionidse, 

 belong a large number of small or medium sized species whose 

 principal distinguishing character is the projecting upwards and 

 outwards of the epimera of the mesosternum (Fig. 22, c ! so that 

 they form a sort of wedge or knob, often visible from above, each 

 side of the body between the base of the thorax and elytra, thus 

 obliquely truncating the humeri and giving the insects an ap- 

 pearance different from that of any other tribe of the subfamily. 

 The liarini are usually compact, robust, elliptical, oval or sub- 

 rhomboidal weevils of a black (rarely brown i hue, having the 

 funicle always 7-jointed. the first and usually the second joint 

 each longer than the third; club annulate; beak variable in form, 

 not received closely upon the prosternum, its antennal grooves 

 usually oblique and rapidly descending, sometimes wholly in- 

 ferior; thorax without postocular lobes, not emarginate beneath 

 and, in most cases, as wide or almost as wide as elytra; scutel- 

 ium distinct; pectoral groove usually wanting; front coxje always 

 more or less separated; legs slender, femora in our genera un- 

 armed (except in Madurcllnx and I'scmlolmrix I . tibia* with a short 

 acute internal spur at apex; tarsi with third joint usually bi- 

 lobed, the claws simple. The beak of the female is nearly always 

 smoother, more slender, somewhat longer, less punctate and more 

 strongly curved than in the male.
