the base; punctures coarse but separated by about their diameters, denser 

 anteriorly as usual, the smooth median line much wider; elytra oval, a fifth 

 longer than wide, only slightly wider than the prothorax and two-thirds 

 longer, the sculpture nearly similar; pygidium similarly small, strongly 

 rounded and just visibly wider than long. Length 2.0 mm.; width 0.85 



mm. Brazil (Santarem). One specimen brunneipes n. sp. 



12 — Body very narrow, parallel and cylindric. Color piceo-rufous throughout, 

 the pronotum somewhat more obscure; squamules yellowish, those of the 

 pronotum extremely fine and not dense, wanting in median third, on the 

 elytra broader, white and conspicuous in single lines, confused basally except 

 toward the sides; on the under surface fine, white and well separated; legs 

 red-brown, beak ( 9 ) slender, only feebly arcuate and distinctly longer than 

 the head and prothorax, the rufous antennae very slightly behind the middle; 

 prothorax a fifth or sixth wider than long, the parallel sides straight, rounding 

 and oblique beyond the middle, the non-tubulate apex just half as wide as 

 the base; punctures very moderate but deep, dense laterally, but distinctly 

 separated toward the wide smooth median line; scutellum small, subglabrous, 

 convex, truncate behind, with sharp angles; elytra fully a fourth longer than 

 wide, the sides parallel and straight, evenly rounded in apical third, excepting 

 the usual reentrant sutural angle, just visibly wider than the prothorax and 

 three-fourths longer; grooves deep, half as wide as the intervals, which 

 have the usual single series of moderately coarse punctures; pygidium small, 

 circularly rounded. Length 2.15 mm.; width 0.75 mm. Brazil (Chapada). 



May. One specimen '. . .angustus n. sp. 



Body broader, oval, always deep black in color 13 



13 — Pronotal punctures strong, but not dense, except toward the sides, generally 

 separated by at least their own diameters; prosternum not spined in the 



male 14 



Pronotal punctures coarse, deep and dense, always closer than their own diam- 

 eters; body deep black, the legs rufous 17 



14 — Legs red 15 



Legs deep black 16 



15 — Form oval, shining; color deep black throughout, excepting the legs; squam- 

 ules throughout above whitish, slender, sparse and distinct though incon- 

 spicuous in single interstitial lines, broader and close beneath on the hind 

 body; beak (cf) notably slender and arcuate, much longer than the head 

 and prothorax, or ( 9 ) scarcely so slender as in the male, rather more thick- 

 ened at base and very little shorter; antennae piceous, at the middle (cf), or 

 distinctly behind the middle (9); prothorax fully two-fifths wider than 

 long, the sides feebly converging and straight, broadly rounding beyond the 

 middle; smooth median line entire; elytra broadly oval, a fifth or sixth 

 longer than wide, slightly wider than the prothorax and not quite twice as 

 long; grooves deep; interstitial punctures strong, rather well separated in 

 the single series; male without distinct sexual modifications. Length 2.4- 

 2.85 mm.; width 1.18-1.35 mm. Brazil (Espirito Santo). Desbrochers des 



Loges. Seven specimens parcus Fst. (MS?) 



Form oval but narrower than in parcus, deep black throughout and rather less 

 shining, the pronotum alutaceous; squamules above almost wholly denuded 

 in specimens at hand, those beneath white and narrowly separated; beak 

 ( 9 ) slender, moderately arcuate, slightly longer than the head and prothorax, 

 the antennae submedial; prothorax less transverse and more parallel, two- 

 fifths to a third wider than long, the arcuate sides gradually becoming 

 subparallel in about basal half; punctures isolated, not so coarse as in the 

 preceding, separated by about their own diameters, dense at the sides as
