and on the third at apical sixth; elsewhere the pale scales are wanting; 

 on the under surface the coarse close punctures have small squamules, which 

 become large and close, whitish scales on most of the presternum, over the 

 nies-epimera and on parts of the metasternum and abdomen; beak (cf) 

 almost evenly cylindrical, not inflated at base as in the preceding, and a 

 third longer than the head and prothorax, the piceous antennae at three- 

 fifths, the club shorter; prothorax a third wider than long, the converging 

 sides subevenly arcuate throughout, the very feebly differentiated tubulation 

 much less than half as wide as the base; punctures very coarse and dense, 

 the carinule nearly flat; basal lobe very broad, obtusely cuspidiform; scu- 

 tellum quadrate, pallidly squamulose; elytra only a fifth longer than wide, 

 parabolic, not a fourth wider than the prothorax and twice as long; grooves 

 coarse and deep; intervals strongly, very densely punctate, the brown scales 

 large and conspicuous; male with the abdomen rather deeply impressed and 

 abruptly subglabrous along the middle basally; prosternum flat, but some- 

 what sparsely squamose. Length 5.4 mm.; width 3.0 mm. Brazil (Cha- 

 pada — campo). October. One specimen breviusculus n. sp. 



Body more narrowly subrhomboid-oval, nearly similar in color and vestiture, 

 except that the pale scales are more ochreous-yellow, form a more definite 

 loose central design on the pronotum and are more extensively sprinkled 

 among the dark brown scales of the elytra, the other elytral condensations 

 nearly similar, the under surface almost similar; beak (o 71 ) subsimilar or ( 9 ) 

 very nearly as in the male, though somewhat longer, the antennse similarly 

 inserted in both sexes; prothorax nearly similar but slightly smaller and a 

 little narrower, coarsely, densely punctate, the median carina still feebler and 

 more indefinite; basal lobe and scutellum subsimilar; elytra narrower, more 

 than a fourth longer than wide, the general form and relationships almost as 

 in the preceding, the grooves not quite so coarse and the close confused 

 interstitial punctures a little smaller; male abdomen much more feebly 

 impressed but subglabrous along the middle basally. Length 4.2-4.8 mm.; 

 width 2.0-2.35 mm. Brazil (Chapada — campo). October. Three speci- 

 mens stabilis n. sp. 



6 — Form more oblong, subrhomboid-oval, with more convex prothorax as seen 

 in profile, deep black, the dark scales throughout not brown as in the pre- 

 ceding species but black, the pale pronotal scales large and sparse, forming 

 a feeble submedial design and distinct antero-laterad; on the elytra nearly 

 white, the dense subbasal entire but irregular fascia with an offset on the third 

 interval, which attains the base, it also curves forward to the humeri at the 

 sides; at three-fifths there is a transversely quadrate spot on each, involving 

 intervals 3-5; on the under surface the large whitish scales are conspicuous 

 on the sterna medially, on most of the abdomen, on the mes-epimera and 

 anterior end of the met-episterna; beak (d") three-sevenths as long as the 

 body, feebly inflated basally, moderately tapering, smoother and thinner 

 distally, or ( 9 ) distinctly more inflated toward base and relatively thinner, 

 smoother and more tapering distally, also relatively much shorter, being 

 only a little longer than the head and prothorax; antennae at three-fifths 

 (o 71 ) or four-sevenths (9), black; prothorax a third (o 71 ) or two-fifths (9) 

 wider than long, the sides rather strongly, subevenly arcuate to the some- 

 what well marked tubulation, which is much less than half as wide as the 

 base in both sexes; punctures very coarse, deep, dense and confused; carina 

 smooth, distinct, broader basally; basal lobe short; scutellum obtrapezoidal, 

 very coarsely punctured, subglabrous; elytra a fourth longer than wide, 

 wider than the prothorax but distinctly less than twice as long, obtusely 

 rounded at apex, with feebly oblique and nearly straight sides; grooves 

 very moderate in width and depth, the intervals densely and confusedly
