BARINI. 



BARIS German 

 Baris xanthii n. sp. 



This species runs in Major Casey's table for the species of 

 Baris to dichotomy 12. The legs are black, the integuments 

 highly polished with a more or less pronounced aeneous lustre ; 

 beak at least two-thirds as long as the prothorax. The species 

 is considerably smaller than B. lubrica, has the beak propor- 

 tionately longer, and the base of the thorax slightly con- 

 stricted, instead of straight as in lubrica. Oblong-oval, rather 

 slender, convex, black throughout, highly polished, with 

 aeneous lustre. 



Head obsoletely punctured ; the beak with elongate shallow punctures 

 in longitudinal lines, arcuate, robust, basal transverse impression distinct; 

 antennae shorter than the beak, club fully one-third the entire length of 

 the antennas. 



Prothorax scarcely one-third wider than long ; sides slightly con- 

 stricted at base, feebly arcuate to apical fourth, thence strongly conver- 

 gent and nearly straight to the apex, base not more than three times as 

 wide as head, feebly concave from sides to the truncate apex of the me- 

 dian basal lobe ; disk without an impunctate area, punctures moderately 

 coarse, smaller at apex, sparse, rather shallow, placed on a surface very 

 minutely punctate, about one-third the width of the scutellum, and sepa- 

 rated by distances greater than their own diameters. 



Scutellum subquadrate. 



Elytra more than one-third longer than wide, less than twice as long 

 as the prothorax, and wider than the latter at the humeri ; sides behind 

 the humeri very feebly convergent, the apex broadly rounded ; disk with 

 moderately coarse, deep, abrupt, finely remotely crenulate grooves, the 

 intervals at least twice as wide as the grooves, flat, each with a series of 

 very small indistinct, moderately distant punctures which are indifferently 

 and irregularly placed on all intervals and confused on the third and all 

 beyond the fifth ; setae minute silvery. 



Abdomen finely, sparsely punctured, the setae of the under surface very 

 fine, but pale and distinct. Legs very short, moderately robust, black, 

 finely and distinctly punctured. Length 3.3 mm. ; width 1.5-1.6 mm. 



This species was described with the type and five topo- 

 types of B. lubrica for comparison and the two appear very
