Brazilian Baring 235 



spines minute and vestigial, forming two very small tubercles. Length 2.7 

 mm.; width 1.2 mm. Brazil (Chapada). March. One male specimen. 



testata n. sp. 



Prothorax more or less inflated, always more narrowed apically 4 



4 — Pale scales yellowish-white, narrowly lineate, loosely distributed, broadly 

 toward the pronotal sides, narrowly so just beyond the middle, and with a 

 small vacant space in the broad basal part, wanting medially, except on the 

 basal lobe, very sparsely scattered toward the sides of the elytra and more 

 closely aggregated on the basal parts of all the intervals, with gradually 

 increasing lengths of the lines inwardly — on the suture extending to about 

 the middle; intervals 1-4 with shorter lines of dense scales behind the middle, 

 the sutural the shortest; under surface rather densely clothed throughout; 

 body black; beak ( 9 ) evenly cylindric and strongly arcuate, black, three- 

 fourths as long as the elytra, the piceous antenna? moderate; prothorax 

 short, one-half wider than long; apex half as wide as the base; converging 

 sides straight, rounding and oblique anteriad; punctures strong and dense; 

 median line scarcely modified; elytra a fifth longer than wide, oval, with 

 narrow apex and reentrant sutural angle, about twice as long as the prothorax; 

 grooves as in the preceding, the confused interstitial punctures smaller and 

 rather feeble. Length 2.6 mm.; width 1.3 mm. Brazil (Chapada). No- 

 vember. One female brevicollis n. sp. 



Pale scales white above and beneath and differently arranged at the sides of the 



pronotum 5

Pronotal scales forming a broadly and completely interrupted sublateral vitta. . 1 1 



6 — Vacant areas of the elytra deep black and sharply defined 7 



Vacant areas more or less suffused with pale scales, the denser design, however, 



evident IO 



7 — Prothorax but slightly transverse 8 



Prothorax strongly transverse -9 



8 — Form elongate-oval, convex, black, the legs long, piceous; pronotum with 

 very few scales outside of the sublateral vittse, which are very slightly 

 interrupted just beyond the middle, and none at all along the middle, the 

 vittae extending laterally at apex to the dense scales of the entire under 

 surface; on the elytra, the pale scales are sparsely scattered toward sides 

 and apex, dense at extreme base and in a narrowly triangular sutural area 

 extending to the middle, the post-median spots oblique and generally ex- 

 tending to the suture, frequently united along the latter with the triangular 

 scutellar area; beak (d") rather thick, cylindric, moderately arcuate and as 

 long as the head and prothorax, or .( 9 ) similar in length but more arcuate 

 and much narrower and smoother beyond the antennae, which are piceous 

 and submedial (9), or near three-fifths (d"); prothorax a fifth wider than 

 long, the feebly arcuate converging sides gradually more arcuate anteriad; 

 punctures dense, moderate but deep; elytra oval, a fifth longer than wide, 

 two-thirds longer than the prothorax, the grooves deep; intervals densely 

 punctate, nearly as in the preceding species; prosternal spines moderate, 

 slender, not separated by a perforate impression. Length 3.8-4.0 mm.; 

 width 1. 75-1. 85 mm. Brazil (Santarem). Eight specimens.. . .picta n. sp. 

 Form more rhombic-oval, the size larger, black, the pale pronotal scales densely 

 covering the entire lateral part, extending down the inferior flanks and along 

 base and apex to the middle, with a small denuded area at the middle of the 

 extreme sides; median area broadly cordiform and entirely devoid of pale 

 scales; on the elytra the pale scales are scattered toward the sides and form 

 a large, posteriorly and obtusely angulate area, involving the entire base
