Brazilian Baring 205 



more arcuate and oblique in about apical half, the gradual and moderate 

 tubulation not half as wide as the base; strigilation fine and dense; scutellum 

 nearly as in the preceding, subglabrous, more impressed medially; elytra a 

 fourth longer than wide, evenly parabolic, slightly wider than the prothorax 

 and twice as long; pale squamules unevenly but, in general, loosely aggre- 

 gated over most of the intervals, which are not very coarsely, somewhat 

 loosely, confusedly and subrugulosely punctate; male with the prosternal 

 spines slender, erect, evidently arcuate and one-half longer than the thickness 

 of the femora. Length 2.65-2.75 mm.; width 1.45 mm. Brazil (Rio de 

 Janeiro). November. Three specimens ovoideus n. sp. 



It is rather remarkable that the last four species were all taken 

 near the same place and at the same season, but, so far as can be 

 determined, they are amply distinct among themselves. 



Centrinopus Csy. 



This genus is allied to Centrinites and is similarly widely distrib- 

 uted in North and South America; the body, however, is much 

 more minute in size, the beak longer, more slender, smoother and 

 less sculptured and, at apex, is slightly dilated and flattened, with 

 the mandibles similar; the line separating it from the head is ex- 

 tremely fine and barely observable. The antennae are slightly 

 behind the middle, slender, the first funicular joint as long as the 

 next three, the outer joints somewhat enlarged and frequently 

 coronate with slender white squamules, and the club is oval, very 

 moderate and rather abruptly formed. The prosternum is similarly 

 impressed but squamose along the middle, and the coxae are moder- 

 ately separated. The pronotum is densely but discretely punctate 

 and the scutellum quadrate and densely squamulose, the elytral 

 striae deep. These characters are taken from the two Brazilian 

 species here described, but do not seem to differ from those of our 

 northern species; no prosternal spines are observable in the only 

 Brazilian male at hand. The two species are not at all closely 

 allied and may be described as follows: 



Body suboblong-oval, convex, very densely and uniformly clothed above and 

 beneath with yellowish parallel scales, those below a little whiter; beak ( 9 ) 

 very slender, subcylindric, three-fourths as long as the elytra, very smooth, 

 shining and glabrous, rapidly becoming closely squamose and gradually 

 slightly thicker basally; prothorax between a fourth and third wider than 

 long, the broadly arcuate sides more oblique in about apical, subparallel in 

 basal, half; punctures strong and extremely close throughout; base recti- 

 linearly transverse, the lobe abruptly formed, short, with truncate apex; 

 elytra a fourth longer than wide, obtusely oval, slightly wider than the 

 prothorax and somewhat less than twice as long; striae deep but not coarse, 

 distinctly parting the dense decumbent vestiture; abdomen very densely 

 and uniformly squamulose, the first suture distinct, arcuate medially, the 

 last three not coarse, strongly reflexed at the sides. Length 2.4-2.5 mm.; 

 width 1.05-1.2 mm. Brazil (Santarem). Two female specimens.
