Brazilian Baring 137 



with prominent and broadly rounded humeri, the oblique sides only just 

 visibly arcuate; apex obtusely rounded; mes-epimera greatly visible from 

 above; strise not coarse but very deep and groove-like, distinctly punctate, 

 the second and third dilated basally; intervals with some minute punctula- 

 tion; presternum broadly before the coxae, sides of the metasternum, the 

 met-episterna and entire first two ventral segments, except at the sides, 

 extremely densely clothed with narrow whitish squamules. Length 7.0-7.2 

 mm.; width 4.7-5.0 mm. Brazil (Chapada — campo). October and No- 

 vember. Two female specimens cupreus n. sp. 



Body more elongate, green or dark blue in color throughout; met-episterna 

 glabrous .3 



3 — Elytral striae fine but deep, the seventh and eighth rather strong, coarsely 

 and deeply grooved posteriorly. Body rhombic-suboval, deep blue, green 

 beneath, the elytra with feeble violaceous reflection; beak subcylindric, 

 rather thick, minutely, sparsely punctate, almost as long as the elytra, nearly 

 straight, rapidly arcuate, thicker and coarsely, confusedly sculptured basally; 

 antennae near basal third, piceous, the notably elongate basal funicular 

 joint as long as the next three, the second twice as long as wide, the club 

 stout, oval, nearly as long as the preceding four joints; prothorax barely 

 more than one-half wider than long, the strongly and subevenly arcuate 

 sides becoming parallel at base; constriction rather strongly, loosely punc- 

 tate; surface finely, remotely punctulate; basal lobe broadly, evenly rounded, 

 having some coarse punctures, the lateral impressions small; scutellum 

 large, smooth, twice as wide as long, parallel, the obtuse apex acicularly 

 cuspid at the middle; elytra barely longer than wide, much wider than the 

 prothorax and nearly three-fourths longer, evenly parabolic, with strongly 

 rounded and prominent humeri; stria? distinct, finely punctulate, coarsely 

 exarate at apex, 2-4 dilated at base; metasternum and abdomen glabrous, 

 minutely, sparsely punctate, the former with a dense area of whitish squam- 

 ules at each side, deeply striate along the middle; presternum less con- 

 spicuously squamulose; femora sparsely punctate and minutely spiculate. 

 Length 6.7 mm.; width 4.4 mm. Brazil (Rio de Janeiro). October. One 

 specimen hyacinthus n. sp. 



Elytral striae extremely fine, almost obsolete, minutely and remotely punctulate, 

 coarsely impressed and exarate at apex, 2-4 dilated at base, the seventh 

 and eighth a little stronger and more evidently punctate but not at all 

 groove-like; presternum and sides of the metasternum with very dense pale 

 squamules 4 



4 — Body not very broadly rhomboid-oval, bright blue in color, the under surface 

 and beak more greenish; beak (o 71 ) very nearly as long as the elytra, moder- 

 ately slender, nearly straight, rapidly arcuate, a little thicker and more 

 coarsely, confusedly sculptured basally, the upper surface there becoming 

 longitudinally obtusely bitumerose or feebly and doubly bent; antennae 

 behind basal third, piceo-rufous, the first funicular joint longer than the 

 next two, the second twice as long as wide, the club rather large, longer than 

 the preceding five joints, asymmetric, more convex externally, widest near 

 basal third, thence gradually becoming finely acuminate at apex; prothorax 

 three-fifths wider than long, the arcuate sides subparallel in less than basal 

 half, obliquely rounding thence to the rather short and scarcely abrupt 

 tubulation, the constriction with numerous moderate punctures; surface 

 with very minute and remote punctulation; basal lobe very broadly, evenly 

 rounded, with a row of coarse punctures, the lateral impressions rather 

 large and deep; scutellum nearly as in the preceding but less transverse; 

 elytra a fifth longer than wide, much wider than the prothorax and two- 

 thirds longer, somewhat narrowly, subevenly parabolic, the humeri strongly
