and abrupt, half as wide as the intervals, which have each a single series of 

 coarse and close-set punctures. Length 2.65 mm.; width 1.28 mm.^ Brazil 



(Chapada— forest). November. One specimen brevicollis n. sp. 



Prothorax less abbreviated, its surface more polished between the punctures. . 10 

 IO — p r onotum conspicuously squamulose throughout, but with the squamules 



more slender and less close-set medially • ....11 



Pronotum sparsely and finely squamulose or, if more distinctly so, with the 



squamules wanting broadly toward the middle 12 



11— Body rather stout, oval, black, the legs and beak rufous; squamules above 

 yellowish, only a little more slender narrowly at the middle of the pronotum; 

 on the elytra conspicuous and close-set in single series, narrowly confused 

 toward base on the inner intervals; whiter and dense beneath, except as 

 usual on the p'ropleura; beak (cf) black, rather thick, very moderately 

 arcuate, feebly tapering, sculptured and longer than the head and prothorax, 

 or ( 9 ) distinctly thinner, similarly arcuate but not quite so long; antennae 

 rufous, slightly beyond (<?) or a little behind ( 9 ) the middle; prothorax a 

 sixth Co 71 ) or a fifth ( 9 ) wider than long, the parallel sides nearly straight, 

 rounding in apical third to the short tubulation, which is just half as wide 

 as the base ( 9 ) or narrower (cf); punctures strong, separated by their 

 diameters or less toward the smooth median line; elytra oval, only very 

 little longer than wide, distinctly wider than the prothorax and one-half (c?) 

 to two-thirds ( 9 ) longer; grooves deep, punctured, fully half as wide as the 

 intervals, having strong and close-set, uniseriate punctures; male abdomen 

 very feebly impressed and abruptly, sparsely and finely squamulose medio- 

 basally, the porrect prosternal spines very slender, testaceous, upwardly 

 somewhat curvate and three-fourths as long as the prothorax in normally 

 developed examples. Length 2.35-2.8 mm.; width 1.1-1.28 mm. Brazil 

 (Chapada— forest). May and November. Thirteen specimens. 



brevipennis n. sp. 

 Body smaller, narrower and more convex, shining, rufous, the elytra alone more 

 obscure; squamules nearly as in the preceding; beak (c?) more slender and 

 more strongly arcuate, sculptured and partially squamulose as usual, very 

 feebly tapering and much longer than the head and prothorax, or ( 9 ) 

 notably shorter, still more slender, smoother, similarly arcuate and very 

 little longer than those parts; antennae (c?) submedial or ( 9 ) near two-fifths; 

 prothorax a fifth (c?) to a fourth (9) wider than long, the parallel sides 

 rounding from nearer the middle; punctures much coarser and everywhere 

 close-set or dense, the median smooth line narrow and sharply defined; 

 elytra a fifth longer than wide, oval, similarly proportioned with regard to the 

 prothorax; sculpture almost similar, the uniseriate punctures of the intervals 

 not quite so coarse ; male abdomen medio-basally abruptly subdenuded but 

 not impressed, the very slender pale porrect prosternal spines varying from 

 very short to about half as long as the prothorax. Length 2.15-2.45 mm.; 

 width 0.9-1. 18 mm. Brazil (Chapada— forest). May and November. On 



flowers as usual. Eighteen specimens seriellus n. sp. 



Body still a little smaller and more narrowly oval than in seriellus, piceous-black, 

 shining, the legs pale red-brown, the squamules rather less conspicuous but 

 with a more evident denser spot at the base of the second strial interval, 

 white beneath but only moderately dense, sparse on the prothorax; beak ( 9 ) 

 piceous, slender, feebly arcuate, longer than in seriellus and much longer 

 than the head and prothorax, the slender rufous antennae only just visibly 

 behind the middle; prothorax longer, scarcely a fifth wider than long, the 

 parallel sides nearly straight, gradually rounding beyond the middle to the 

 non-tubulate apex, which is wider and evidently more than half as wide as
