Brazilian Baring 333 



punctures small and rather sparse, though evidently larger and smaller 

 intermingled, the single series of interstitial setae entire 4 



Body broader and strongly depressed, smoother, the discal pronotal punctures 

 fine, sparse and subeven in size; interstitial series of setae wanting, except 

 at apex • ' • 



4 — Form rather more oblong-oval than in the two preceding, feebly shining, 

 castaneous, more rufous beneath; vestiture nearly as in the preceding species; 

 beak slender, almost straight, not quite as long as the prothorax, feebly 

 tapering in profile but, as in the two preceding, rather abruptly narrower- 

 viewed dorsally — beyond the antennae, smooth distally, punctured and 

 setulose basally, the antennae at two-fifths, the scape rather short; prothorax 

 a fourth wider than long, subinflated, the sides broadly, subevenly arcuate 

 throughout, gradually more converging beyond the widest part, which is 

 near basal third; punctures small and sparse, rapidly coarse, uneven and 

 dense at the sides; median smooth line wide and well defined, not tumid, 

 obsolete at apex and broadest at the middle; elytra a third longer than wide, 

 parabolic, somewhat strongly rounded at tip, less than a fifth wider than the 

 prothorax and scarcely twice as long; grooves less coarse than in the pre- 

 ceding and distinctly but less coarsely and more closely punctured, scarcely 

 more than half as wide as the intervals, which have the rather coarse but 

 very shallow punctures distinct; abdomen with the first two segments 

 extremely minutely and remotely punctate, somewhat flattened discally; 

 pronotum with a feeble rounded impression at each side at outer fourth and 

 basal third. Length 3.2 mm.; width 1.35 mm. Brazil (Santarem). One 

 specimen repentina n sp. 



Form nearly similar but larger in size and nearly black, the legs and under surface 

 rufo-piceous; vestiture as in the preceding, the elytral setae a little longer 

 and more distant; beak similar but very slightly longer, the antennae almost 

 similar; prothorax nearly similar in outline but longer, scarcely a fifth wider 

 than long; basal lobe smaller and feebler; surface without trace of the two 

 impressions of the preceding type; punctures and smooth median line 

 nearly similar; elytra scarcely a third longer than wide, parabolic, more 

 obtusely rounded behind, only a little wider than the prothorax and four- 

 fifths longer, the humeri similarly feebly prominent; grooves deep, half as 

 wide as the intervals, evidently but not conspicuously punctured along the 

 bottom, the intervals flat, with the large but shallow punctures much more 

 widely separated, the ninth similarly cariniform internally; abdomen nearly 

 similar. Length 3.7 mm.; width 1.7 mm. Brazil (Santarem). One 



specimen subulifera n. sp. 



5 _Body oblong-oval, strongly depressed, more shining, deep black, the under 

 surface and legs rufo-piceous; upper surface wholly glabrous and smooth, 

 excepting a few erect setae at the elytral apex; under surface with the squam- 

 ules very minute and sparse throughout; beak black, nearly straight, very 

 smooth, somewhat flattened, thick, punctured and setulose in basal third, 

 the dorsal aspect as in the preceding species; antennae at two-fifths, piceous, 

 the scape capitate; prothorax a fifth wider than long, the sides subevenly 

 arcuate, feebly so and more parallel behind, a little more strongly toward 

 the constriction, the very abrupt short tubulation scarcely more than two- 

 fifths as wide as the base, the latter coarsely grooved, the wide and very 

 feeble lobe narrowly extending across the groove; punctures very fine and 

 remote, rapidly somewhat coarse but well separated at the sides, the smooth 

 median line not crossing the apical constriction; elytra obtusely oval, 

 subparallel basally, not quite a third longer than wide, at the obtusely 

 prominent humeri evidently wider than the prothorax, four-fifths longer; 

 grooves less than half as wide as the intervals, moderately punctate, the 

 intervals flat, each with a series of very minute punctures, which become
