Brazilian Baring 339 



(cf ) to fourth ( 9 ) longer than wide, very slightly wider than the prothorax 

 and one-half longer; grooves coarse and deep, as wide as the intervals, 

 except internally, the interstitial punctures small but deep, in single series 

 on the narrower, sparser, more minute and confused on the inner broader, 

 intervals; abdomen rather strongly punctate and very finely squamulose, 

 feebly impressed at the middle basally in the male, the prosternal spines 

 slender, more than half as long as the prothorax in the type. Length 3.65- 

 3.75 mm.; width i. 6-1.7 mm. Brazil (Chapada). May. On flowers. A 

 single pair lateralis n. sp. 



Form rather more oval and smaller, deep black and shining throughout; beak 

 (cT) nearly as in the preceding, somewhat shorter than the prothorax, or ( 9 ) 

 somewhat more slender and fully as long as the prothorax; antennae piceous, 

 medial in both sexes; prothorax a fifth (d") to a fourth ( 9 ) wider than long, 

 the sides parallel and distinctly, subevenly arcuate, rapidly rounding and 

 very convergent in apical third or fourth; tubulatioh distinct, somewhat 

 less than half as wide as the base; punctures nearly as in the preceding; 

 scutellum with similarly oblique sides; elytra similar in the sexes, a fourth 

 longer than wide, rapidly oval, barely visibly wider than the prothorax and 

 one-half longer or less; sculpture almost similar, the eighth and ninth inter- 

 vals similarly cariniform; presternum with a small deep apical fossa (9), 

 or with a large impression and two slender processes (o 71 ), the processes 

 similarly piceo-rufous, three-fifths as long as the prothorax; abdomen scarcely 

 modified in the male; size and outline of the body much more nearly identical 

 in the sexes than in the preceding species. Length 3.2-3.5 mm.; width 1.5- 

 1.6 mm. Brazil (Santarem). Three specimens amazonica n. sp. 



5 — Body rather broad, depressed, with subinflated prothorax, deep black through- 

 out, the legs black and notably short as usual; beak (9) feebly, evenly 

 arcuate, only three-fourths as long as the prothorax, feebly punctulate, 

 cylindric and notably slender, rather abruptly thicker, punctured and 

 minutely, loosely squamulose behind the antennae, which are near basal third 

 of the lower profile, blackish; prothorax rather wider at the middle than at 

 base, a fifth wider than long, the sides distinctly arcuate, more rapidly 

 rounded and converging beyond about the middle to the extremely short 

 and feeble tubulation, which is much less than half as wide as the base; 

 punctures laterally very coarse, deep and separated by nearly their own 

 diameters, rapidly becoming fine and very remote discally; elytra oval, 

 scarcely a fourth longer than wide, barely as wide as the prothorax and one- 

 half longer, the humeri not prominent; grooves deep, evidently punctured, 

 a third as wide as the intervals internally, but fully as wide as the latter 

 externally, the eighth and ninth intervals somewhat cariniform; interstitial 

 punctures minute and sparse, a little stronger and in single lines laterally; 

 scutellum flat, not quite as wide as long, obtrapezoidal; metasternum 

 coarsely, loosely punctate and feebly squamulose. Length 4.0 mm.; width 

 1.8 mm. Brazil (Chapada — forest). November. One specimen. 



robustula n. sp. 



Body distinctly narrower; coloration and lustre similar; beak (9) similar but 

 still somewhat shorter, or (o 71 ) much thicker, not tapering, more feebly 

 arcuate and somewhat less than three-fourths as long as the prothorax; 

 antennae nearly similar, medial (o 71 ), at basal third ( 9 ), blackish; prothorax 

 nearly as long as wide, the sides less arcuate, similarly rounding beyond 

 about the middle, there only just visibly wider than at base, the longer 

 tubulation much ( 9 ) or only slightly (d") less than half as wide as the base; 

 punctures laterally coarse and deep, but not so large or widely spaced as in 

 the preceding, rapidly fine and remote on the disk but less remote than in
