Brazilian Baring 241 



as the prothorax; grooves moderately coarse, deep, the intervals with fine, 

 confused and well separated punctures; male with very feeble abdominal 

 characters, the prosternal spines very short, slender and erect. Length 2.7 

 mm.; width 1.38 mm. Brazil (Entre Rios). September. One example. 



relicta n. sp. 



3 — Scales of the elytra broader, forming a dense crust parted by the deep striae. 

 Oblong-oval, the integuments black, the legs obscure rufous; dense scales of 

 the upper surface uniformly ochreous, a little broader and denser at the 

 sides of the pronotum than medially, whiter, broad and forming a dense 

 crust throughout beneath; beak (o 71 ) nearly two-thirds as long as the elytra, 

 rather more arcuate distally than basally, punctate and squamose through 

 the greater part of the sides, the antennae piceous, moderately long, sub- 

 medial; prothorax a third wider than long, the arcuate sides subparallel 

 basally, more oblique anteriorly, the apex less than half as wide as the base; 

 punctures moderate, dense; basal lobe and small scutellum with very dense 

 whiter scales; elytra elliptic, a fourth longer than wide, not quite twice as 

 long as the prothorax; striae deep, a third or fourth as wide as the very 

 densely squamose intervals; male with the abdomen slightly impressed and 

 less squamose medio-basally, the prosternal spines short, slender, straight and 

 slightly oblique. Length 2.4 mm.; width 1.23 mm. Brazil (Chapada — 

 forest). August. One male specimen ingeniosa n. sp. 



Scales of the entire upper surface very narrow and slender, abundant and uniform, 

 but not forming a dense crust on the elytra; body more minute 4 



4 — Form oval, the integuments piceous, with rufous legs; squamules above 

 yellowish, very close but not in mutual contact, uniform; whiter, broader 

 and dense beneath; beak (c?) slender, very strongly arcuate, just visibly 

 tapering and smooth distally, squamulose basally, the antennae rufous, very 

 slightly behind the middle; prothorax very nearly as long as wide, the 

 converging sides subevenly and feebly arcuate, the apex not at all tubulate 

 and half as wide as the base; punctures dense; scutellum well developed 

 and with coarse, whitish scales, like those of the thoracic lobe; elytra rather 

 broadly parabolic, not a fifth longer than wide, a fourth wider than the 

 prothorax and two-thirds longer; striae moderate, the interstitial punctures 

 close-set; male with the abdomen scarcely modified, the prosternal spines 

 short, slender, erect and obscure rufous. Length 1.8 mm.; width 0.8 mm. 

 Brazil (Chapada). June. One specimen timida n. sp. 



Form narrower and more elongate-oval, rufo-piceous, with red legs; squamules 

 above yellowish, even smaller, finer and more distinctly separated than in 

 the preceding, uniform; paler, gray and denser beneath; beak (c?) a little 

 longer and still more strongly arcuate, nearly three-fourths as long as the 

 elytra, cylindric, only just visibly tapering distally, punctulate and squamu- 

 lose basally; antennae piceous, submedial, not so evidently behind the middle 

 as in the preceding; prothorax only a fifth or sixth wider than long, the sides 

 feebly arcuate and subparallel basally, thence oblique and straighter to the 

 non-tubulate apex, which is evidently a little less than half as wide as the 

 base; punctures dense; median line very faintly prominent; scutellum 

 much smaller and narrower, very densely clothed with much smaller squam- 

 ules; elytra more elongate, oval, more narrowly rounded at tip, three-fourths 

 longer than the prothorax, the sutural angle, as usual in this group, not at 

 all reentrant; striae much coarser, the squamules of the narrower intervals 

 more nearly in two irregular lines; male with the abdomen not at all modified, 

 the prosternal spines oblique, slender, rufous, slightly arcuate and three- 

 fifths as long as the prothorax. Length 1.88 mm.; width 0.8 mm. Brazil 

 (Chapada). May. A single male example subangusta n. sp. 



Form still narrower, the body more minute than in any other species; pale
