24 Memoirs on the Coleoptera 



except in a narrow oblique entire line at each side; on the elytra the vestiture 

 in the type is mostly denuded accidentally, but the fulvous scales seem to be 

 rather sparse and are variegated posteriorly with white flecks; on the under 

 surface the pale scales are narrowly separated, becoming fine and incon- 

 spicuous on the met-episterna and broadly denuded on the prothorax basally; 

 beak feebly, evenly arcuate, shorter, barely longer than the head and pro- 

 thorax, rather thick, abruptly less so beyond the antennae, which are at 

 three-fifths, the club elongate-oval, the first two funicular joints notably 

 elongate, the third more than half as long as the second; prothorax shorter 

 than in the preceding section, nearly one-half wider than long, the evenly 

 converging sides broadly arcuate; apex nearly half as wide as the base, the 

 prominent basal lobe rounded; punctures rather strong, dense, longitudinally 

 united; carina distinct, with fine summit; scutellum short and transverse, 

 the cusp acute; elytra of the usual form and proportion, much wider than 

 the prothorax, differing from any other species in having the flat and coarsely, 

 densely punctured intervals carinate laterally and posteriorly; striae rather 

 coarse and deep; legs as usual; abdominal impression narrow, feeble and 

 not differently clothed in the male. Length (c?) 5-3 mm.; width 2.8 mm. 

 Brazil (Santarem). One specimen parvula n. sp. 



8 — Prothorax black, with an even white arcuate squamose line extending from 

 before each coxa transversely outward, bending backward to the base, 

 becoming visible from above, also with a median elongate-oval and more 

 anteriorly pointed spot of dense orange scales on the pronotum, widest be- 

 hind the middle and extending from apex to base. Elytral ground opaque, 

 velvety-black, finely densely punctate like the black pronotal areas, the trans- 

 verse entire fasciae whitish, clearly defined and dense, the anterior unevenly 

 arcuate, at two-fifths, the posterior at three-fourths, not attaining the sides 

 and forming an even chevron, the apex also densely whitish; under surface 

 densely albido-squamose on the entire mes-episterna, at the anterior end of 

 the met-episterna and at the sides of the abdomen; beak as long as the head 

 and prothorax, feebly arcuate, rather thick, a little less so beyond the an- 

 tennae, carinate dorsally and squamose basally, finely punctured and nude 

 beyond the antennae, which are medial and of the usual structure, the club 

 oblong, pointed apically; prothorax conical, with nearly straight sides, a 

 little wider than long, the median carina moderate and not exposed; scu- 

 tellum flat, the apex briefly aciculate; elytra of the usual form in the pre- 

 ceding species, much wider than the prothorax, the striae rather fine; intervals 

 flat on the flanks — more broadly behind — having each a very fine medial cari- 

 nule. Length (a 71 ) 7.3 mm.; width 4.3 mm. Brazil (Chapada). One 

 specimen centralis n. sp. 



Prothorax with the same densely squamose inferior whitish line as in the pre- 

 ceding, except that it is wider anteriorly, involving the entire exterior pronotal 

 edge, but the entire pronotum, having the line mentioned as a lateral limit, 

 is uniformly and densely clothed with pale linear scales, with a short trans- 

 verse basal denuded spot at each side of the middle 9 



9 — Strial interval behind the humeri alone carinulate and, even this, not traceable 

 much behind the middle. Body rhombic, convex, black, the antennal 

 funicle dark rufous; dense vestiture of the pronotum and scutellum fulvous, 

 becoming whitish on the basal lobe and elytral humeri; anterior whitish 

 fascia of the elytra straight from suture to fifth stria; at two-fifths a dis- 

 connected broader straight fascia extends from the fifth stria to the margin; 

 at apical third there is an angulate fascia, not extending to the margin, the 

 anterior apex of which is connected on the suture with the anterior fascia 

 by a narrow and partially fulvous white vitta; apex loosely white, except 

 on the suture; beak rather longer than the head and prothorax, formed as
