Brazilian Baring 453 



the scape slightly longer than the club, which is normal, evenly oval and 

 subequally divided by the sutures, feebly fusco-pubescent; prothorax a 

 fourth wider than long, the sides feebly convergent and very slightly arcuate, 

 gradually more rounding in apical third; basal lobe obtusely rounded; 

 punctures coarse, subrugosely close laterally, gradually smaller and separated 

 by fully their own diameters medially, where they are normally coarse basally 

 as usual; median smooth line not evident; scutellum small, rounded and 

 feebly impressed ; elytra with moderately oblique and slightly arcuate sides, 

 rather rapidly obtusely rounded at apex, a third longer than wide, evidently 

 wider than the prothorax and nearly three-fourths longer; grooves deep, 

 abrupt and subequal throughout, punctulate and more than half as wide as 

 the intervals, which are sparsely and scarcely visibly, infinitesimally punctu- 

 late; pygidium broadly, longitudinally tumid; tarsal claws slender, diver- 

 gent. Length 3.2-3.45 mm.; width i. 3-1. 5 mm. Brazil (Chapada — forest). 

 March and November. Two specimens ; . . .lyratulus n. sp. 



Prosternal lobe more finely and evidently more sparsely punctate, shining and not 

 so deeply concave 7 



7 — Body evenly oval, convex, shining and black; beak (o 71 ) rather thick and 

 short, evenly and moderately cylindric and arcuate, moderately closely 

 punctate, somewhat more strongly gradually toward base, shorter than the 

 prothorax, or ( 9 ) as long as the head and prothorax, otherwise nearly as in 

 the male; antennae medial (d*), slightly post-medial (9), the club oval, 

 normal; prothorax larger, a fourth wider than long, the sides subparallel 

 and barely arcuate, broadly rounding and oblique in about apical third; 

 apex rather more than half as wide as the base; basal lobe gradual, narrowly 

 rounded at tip; punctures coarse and narrowly separated laterally, much 

 smaller and separated by twice their widths medially throughout the length, 

 with a very feebly defined subimpunctate median line; scutellum small, 

 flat, scarcely as wide as long, close-set and ogival, the elytra evenly oval, a 

 fourth Longer than wide, very slightly wider than the prothorax and barely 

 three-fifths longer; grooves rather coarse, deep, exarate distally; punctures 

 of the regular interstitial series very minute; pygidium evenly convex (o 71 ), 

 smaller ( 9 ) ; abdomen rather closely punctate at base, apex and sides, . 

 without trace of basal impression in the male type; prosternum with a 

 somewhat deep apical sinus as usual. Length 2.65 mm.; width 1.25 mm. 

 Brazil (Chapada). May and January. Two specimens veridicus n. sp. 



Body nearly as in the preceding but subaeneous; beak ( 9 ) shorter, not as long 

 as the prothorax, moderately thick, not swollen basally, evenly and moder- 

 ately arcuate, feebly tapering and almost smooth distally, gradually closely 

 punctured basally, shorter than the prothorax; antennae piceous, barely 

 visibly behind the middle; prothorax a fifth wider than long, the feebly 

 converging sides gradually more rounding toward apex, the latter distinctly 

 more than half as wide as the base; punctures deep, rather coarse, dense 

 laterally, even in size medially, a little less coarse and separated by more 

 than twice their diameters in basal, and much less in apical, half, without 

 smooth median line; scutellum very small, rounded, close-set; elytra evenly 

 oval, a fourth longer than wide, only slightly wider than the prothorax and 

 three-fifths longer; grooves nearly as in the preceding, except that the first 

 does not approach the base so closely; they are coarsely exarate distally; 

 pygidium very small, abruptly and narrowly tumid along the median line. 

 Length 2.65 mm.; width 1.2 mm. Brazil (Chapada — forest). November. 

 One specimen tersus 'n. sp. 



Body larger and stouter than in the two preceding, shining and deep black, 

 suboblong-oval, convex; beak (o 71 ) thick, feebly and evenly arcuate, rather 

 closely punctate and as long as the head and prothorax, the antennae barely
