Brazilian Barin^e 381 



Antennal club very long, as long as the scape and very much longer than the 

 entire shaft; prothorax a truncated cone, the sides very nearly straight; 

 body very much smaller and narrower than in any other species; beak 

 strongly, evenly arcuate, the antennae medial in the type, which is apparently 



a male. [Leptomadarus n. subgen.] 8 



2 — Prothorax more or less inflated, rapidly narrowed anteriorly 3 



Prothorax more conical, the sides almost evenly and only very moderately arcuate 



throughout 7 



3 — Body notably broad in form 4 



Body much more narrowly elongate-oval and smaller in size 6 



4 — Distal joints of the antennal funicle distinctly transverse. Body smooth, 

 deep black, the four elytral pale spots rather dull in color; legs deep black 

 (0"), the femora somewhat piceous (9); beak (d 1 ) rather more than half 

 as long as the body, finely but deeply, sparsely punctate, not very evidently 

 crenulate but strongly fringed beneath, the antennae at apical third, or ( 9 ) 

 much shorter, evenly and strongly arcuate, smooth and feebly narrowed 

 beyond the antennae, which are at four-sevenths as usual, separated from the 

 head by an extremely feeble impression; prothorax a sixth (cf) or a fifth ( 9 ) 

 wider than long, the distinct tubulation not defined by a transverse con- 

 striction and much less than half as wide as the base; surface almost com- 

 pletely smooth; elytra three-fifths ( 9 ) to three-fourths (d 71 ) longer than 

 wide, elongate-suboval, but obtuse at apex, and with slightly tumid humeri, 

 a little wider than the prothorax and four-fifths longer, the striae discally 

 very fine and subobsolete, evident but fine at the sides, very coarse, deep 

 and exarate in nearly apical fifth; male abdomen with a simple deep medio- 

 basal impression, the sides of which, except at base, are densely brunneo- 

 setulose; pygidium (cf) nearly twice as wide as long, densely punctate, or 

 ( 9 ) a little less wide though otherwise nearly similar. Length 8.8-9.5 mm.; 

 width 3.8-4.0 mm. Brazil (Santarem). Seven specimens. 



quadripustulatus Fabr. 

 Distal funicular joints subquadrate, only very slightly wider than long (cf), 



very slightly more transverse ( 9 ) 5 



5 — Color, lustre and sculpture nearly as in the preceding, the elytral rufous spots 

 similar; legs deep black throughout; beak (o 71 ) just visibly more than half 

 as long as the body, finely but strongly, loosely punctate, its under surface 

 feebly crenulate and with a dense fringe; antennae piceous, at apical third; 

 prothorax longer, a fifth wider than long, the strongly arcuate sides very 

 converging anteriad, the tubulation strong, defined by a fine and feebly 

 impressed line, scarcely three-sevenths as wide as the base; surface smooth, 

 excepting the usual remote and infinitesimal punctulation; scutellum 

 strongly, transversely lunate and rather small, almost four times as wide as 

 its median length; elytra three-fifths longer than wide, very slightly wider 

 than the prothorax and three-fourths longer, the feebly oblique sides nearly 

 straight, circularly rounding at apex, with the usual reentrant sutural angle, 

 the humeri feebly tumid; sculpture similar; pygidium nearly as in the 

 preceding, but a little larger and rather less densely punctured, with the 

 median line more strongly tumid; medio-basal abdominal impression more 

 oblong, with the setiform hairs at the sides posteriorly somewhat longer and 

 finer than in the preceding. Length 10.2 mm.; width 4.28 mm. Brazil 



(Santarem). One specimen barbatulus n. sp. 



Color, lustre, sculpture and general features as in the preceding, the legs even 

 somewhat longer and deep black in both sexes; beak (d 71 ) longer, very nearly 

 as long as the elytra, coarsely serrato-crenate beneath and with a long 

 conspicuous fringe, finely but strongly, sparsely punctate, or ( 9 ) shorter,
