large quadrate denuded spot at base and nearer ther" middle than each side; 

 scutellum with close yellowish squamules, transverse, aciculate medially 

 behind; elytra with close fulvous squamules, variegated with small yellowish 

 areas, the squamae not notably oblique; under surface with loose yellowish 

 linear squamae, becoming fulvous laterally on all the sterna; beak fully 

 half as long as the body, moderately thick, closely sculptured, more finely 

 and sparsely distally, straight, arcuate in apical half; antennae long, medial, 

 the cuter joints not coronate — as usual in the genus and unlike Eurypages; 

 prothorax large, two-fifths wider than long, the sides parallel in less than 

 basal half, then rapidly converging and feebly arcuate to the slightly con- 

 stricted apex, which is barely two-fifths as wide as the base; lobe large, 

 rounded, nude; medial carina visible only centrally; punctures strong and 

 very dense; elytra triangular, with broadly rounded tip, not a fourth longer 

 than wide and a fourth wider than the prothorax, less than twice as long as 

 the latter; striae strongly and closely punctate; intervals all strongly and 

 subevenly carinate, less definitely so at base. Length (c?) 8.7 mm.; width 

 5.4 mm. Brazil (Chapada). One specimen amplicollis n. sp. 



Body smaller, less obese; abdomen broadly, feebly concave and glabrous medially 

 at base in both sexes 3 



3 — Form rhombic-oval, broadly convex, black, the antennae rufous, with black 

 club; pronotal squamules rather small, not very close, fulvous, of a lighter 

 shade in a feebly defined oblique sublateral line, in a lateral connecting area 

 just behind the middle and on the median line basally, also on the scutellum, 

 very sparse in a large basal area at each side of the middle; on the elytra 

 fulvous, closer in a broad vague subapical fascia and in some other un- 

 definable fasciiform areas, which are separated by subdenuded spaces; on 

 the under surface moderately close and pale brownish-yellow; beak in 

 general form and sculpture as in the preceding, though slightly more slender, 

 rather more than half as long as the body and with the antennae medial in 

 both sexes, a little longer and more slender in the male; prothorax not so 

 large and fully a third wider than long, the sides strongly converging and 

 broadly arcuate anteriorly, gradually broadly rounding basally, becoming 

 nearly parallel near base, the latter deeply bisinuate, with large rounded lobe; 

 carina visible and nude only centrally; punctures rather coarse, densely 

 confluent; scutellum as in the preceding; elytra similar but rather narrower, 

 less obtuse at apex, the punctures and carinas similar. Length (o 71 ?) 

 6.2-7.0 mm.; width 4.0-4.4 mm. Brazil (Chapada). October. Found in 

 the campo region. Four specimens chapadana n. sp. 



Form and size nearly as in the preceding, the prothorax with more evenly arcuate 

 converging sides throughout and widest more nearly at the base, the fulvous 

 squamules variegated with whitish at the sides, at apex and base of the still 

 more indefinite oblique line, and in a transverse post-median external spot; 

 elytra nearly similar but with rather coarser variegated squamules, which 

 are more whitish in the paler areas; dense and slender squamules of the under 

 surface more whitish and faintly variegated with reddish-brown, the large 

 glabrous ventral space at base still less concave, almost flat; beak similar, 

 the antennal club a little larger and rather more elongate, gradually very 

 acutely pointed; pronotal punctures still coarser, coalescent, the elytral 

 sculpture almost similar; hind femora more coarsely squamose, the scales 

 whitish and not fulvous as they are in the preceding. Length ( 9 ) 7.2 

 mm.; width 4.4 mm. Brazil (Chapada — campo). December. One specimen.

4 — Body broadly rhomboidal, black, shining; pronotum strongly convex in 

 profile, more sloping anteriorly, sparsely, evenly clothed with fine hair-like 

 fulvous scales, whitish at the anterior and posterior angles; scutellum with
