Brazilian Baring 291 



where there are also scattered minute punctures, the median line indefinitely 

 somewhat less punctate; scutellum free, rather longer than wide, narrowed 

 at base, with very oblique straight sides; elytra very obtusely oval, a fourth 

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

 grooves abrupt but not very deep and with distinct punctures along the 

 bottom, a third as wide as the fiat intervals, which have rather small, moder- 

 ately separated punctures in single series; abdomen in the type convex, 

 finely, shallowly and sparsely punctate and with a feeble though obvious 

 impression medially at base. Length 3.3 mm.; width 1.65 mm. Brazil 

 (Santarem). One specimen sparsa n. sp. 



Body smaller and more narrowly oval, dark, the legs and under surface brighter, 

 rufous, the very sparse vestiture nearly as in the preceding; beak in the 

 type cylindric and finely, rather more closely punctate, but very much 

 shorter, not quite as long as the head and prothorax, feebly arcuate, the 

 antennae near two-fifths; prothorax a fourth wider than long, nearly as in 

 the preceding, the minute punctures medially less evident; scutellum smaller 

 and shorter, barely as long as wide, the sides rather less converging from 

 apex to base; elytra as in sparsa, but with the grooves less coarse and not 

 evidently punctate, the punctures of the single interstitial series a little 

 coarser; abdomen in the male type feebly, loosely punctate, with a distinct 

 simple impression medially at base. Length 2.6 mm.; width 1.2 mm. 

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



Body smaller, much narrower and more parallel, shining, piceous, the elytra dull 

 rufous; vestiture very fine, sparse and indistinct on the pronotum, the 

 squamules moderately long, distinct and well separated in single lines on 

 the elytra, the scales small, sparse and inconspicuous beneath; beak (9) 

 long, not very slender, four-fifths as long as the elytra, strongly sculptured 

 and separated from the head by an abrupt and rather deep sulcus, which is 

 not evident in the other species; antennae medial; prothorax barely wider 

 than long, the sides nearly straight and barely visibly converging, rapidly 

 rounding and oblique in nearly apical third to the extremely brief and feeble 

 tubulation, which is not quite half as wide as the base; punctures coarse, 

 close, somewhat sparse and a little less coarse, without intermingled smaller 

 punctures medially, the smooth median line distinct; basal lobe small, 

 without the apical notch of the two preceding; scutellum small, barely as 

 long as wide, narrowed at base and feebly impressed — flat in the other two 

 species; elytra nearly a third longer than wide, slightly wider than the 

 prothorax and three-fourths longer, the arcuate sides more oblique than in 

 the others, the apex more narrowly rounded; grooves deep, impunctate, 

 half as wide as the intervals, which have the punctures of the single series 

 small and widely separated; abdomen rather coarsely, deeply punctate. 

 Length 2.1 mm.; width 0.9 mm. Brazil (Santarem). One specimen. 



nana n. sp. 



I am inclined to think that sparsa is described above from the 

 female, notwithstanding the evident medio-basal abdominal im- 

 pression, and brunnea from the male, but it hardly seems probable 

 that they constitute a single species, because the size and coloration 

 differ considerably and, besides this, the scutellum is of different 

 size and shape, and, more especially, the elytral grooves in brunnea 

 are less coarse than in sparsa and without the very evident punctures 

 of that species. 



There can be scarcely any doubt that nana will have to be
