and, on the suture, extending slightly beyond two-fifths, the two post- 

 median spots narrowly uniting on the suture but separated from the basal 

 area; white scales of the under surface extremely dense throughout; beak 

 ( cf) somewhat arcuate, cylindric, not quite as long as the head and prothorax, 

 the rufous antennae rather long, submedial; prothorax large, a fourth wider 

 than long, the converging sides subevenly and strongly arcuate, becoming 

 slightly sinuate at apex; punctures small and dense, the dark scales very 

 deep brown; elytra parabolic, rather more than a fourth longer than wide, 

 evidently wider than the prothorax and three-fourths longer, with somewhat 

 prominent humeri; grooves deep, the densely punctate intervals nearly as 

 in the preceding species; abdomen of the male scarcely at all modified at 

 base, the erect prosternal spines slender, rather short, with their apices 

 slightly refiexed. Length 4.2 mm.; width 2.2 mm. Brazil (Chapada — 

 campo). October. One male example pernota n. sp. 



9 — Body somewhat broadly oblong-suboval, black, with rufous legs; sublateral 

 pronotal vittae at outer fourth broad basally, narrow and oblique anteriorly 

 and often narrowly interrupted beyond the middle, extended laterally at 

 apex to connect with the densely squamose under surface; median line very 

 narrowly and loosely albido-squamose; extreme sides loosely albido-squam- 

 ose, this area clearly separated from the abrupt upper limit of the dense 

 inferior flanks, which is slightly below the obtuse edge; elytra with scattered 

 white scales broadly toward the sides, these dense and forming a large 

 subquadrate scutellar area, broader at base and occupying basal third, the 

 post-medial spots formed by short lines on intervals 2-4 and always widely 

 separated from the scutellar area; beak ( 9 ) as long as the head and pro- 

 thorax, slender and nearly straight, arcuate but not much thicker in about 

 basal half, the pale antennae slightly behind the middle; prothorax fully 

 two-fifths wider than long, the sides strongly arcuate, parallel basally, the 

 apex very briefly and feebly prolonged, much less than half as wide as the 

 base; punctures moderate and very dense, the dark scales rather wide, 

 blackish-brown; elytra much narrowed behind, subparabolic, a fourth longer 

 than wide, with reentrant sutural angle, not quite twice as long as the pro- 

 thorax; surface rather finely and closely punctate, the grooves moderate. 

 Length 3.4-3.7 mm.; width 1.7 -1.85 mm. Brazil (Chapada). November. 

 Six specimens graphica n. sp. 



Body nearly as in the preceding in form, coloration and sculpture, also in general 

 scheme of ornamentation, except that the lateral pale scales of the pronotum 

 are more extended in area, joining the sublateral vitta near the middle and 

 gradually merging into the dense scales of the inferior flanks without break, 

 and that, on the elytra, the dense basal area is broadly subtriangular, extend- 

 ing almost to the middle and separated from the large post-median spots by 

 a very narrow space — -sometimes connected with the latter along the second 

 interval, the beak (9) nearly similar; prothorax shorter, almost one-half 

 wider than long, the sides more rapidly oblique anteriorly and the pale 

 scales along the median line more obvious as a rule; elytra almost similar, 

 but more nearly twice as long as the prothorax; legs piceo-rufous. Length 

 3.6 mm.; width 1.75 mm. Brazil (Chapada). November. One female 

 specimen decora n. sp. 



ro — Form nearly as in the two preceding, black, the pronotal pale scales disposed 

 almost as in decora, but occupying still more of the surface, the large median 

 area not so broad and with a confused mixture of whitish and dark brown 

 scales; elytra with the parallel white scales distributed almost throughout 

 the surface, but denser on the first and second intervals almost throughout 

 the length, and on the third and fourth behind the middle for a fourth the 

 length; just before and behind the latter two short lines, there is a small
