as usual, the punctures small, deep and rather sparse; fifth ventral simple, 

 deflexed apically; prosternum strongly punctate, with a broadly concave 

 channel, separating the coxae by three-fourths their width, the posterior lobe 

 discontinuous with the mesosternum, narrowly canaliculate, the surface 

 tumid at each side of the impression. Length 5.7-6.7 mm.; width 3.7-4.2 

 mm. Brazil (Chapada). November. Two specimens azureatus n. sp. 



12 — Body broad, rhombic-oval, polished, deep and pure cupreous in color, the 

 legs violaceous-blue; beak (9) thick, cylindric, cupreous, black in nearly 

 distal half, as long as the head and prothorax, the head having a large inter- 

 ocular indentation; punctures minute and sparse; antennae at three-fifths, 

 the funicle thick, narrowed basally, the indentation of the joints deep, 

 forming almost a continuous channel; prothorax strongly, evenly convex 

 in profile, one-half wider than long, the strongly arcuate sides becoming 

 almost parallel and straight in nearly basal half; tubulation abrupt but 

 with oblique sides, about three-sevenths as wide as the base; punctures 

 scarcely visible; lobe very broadly rounded; triangular scutellum nearly 

 smooth, slightly transverse, with straight sides; elytra scarcely as long as 

 wide, the humeral prominences only moderate and obtusely rounded; outline 

 behind them very broadly parabolic; striae very fine but rather deep and 

 distinct, finely, indistinctly lineato-punctate, the coarser first stria deeply 

 grooved and impunctate, feebly crenulate and coarser at base; pygidium of 

 the usual form, finely, loosely punctate; sterna medially and the abdomen 

 greenish, the fifth segment reflexed at tip but not at all foveate. Length 

 7.7 mm.; width 5.0 mm. Brazil. Locality unrecorded. One specimen. 



cupratus Germ. 



Body much smaller in size, less broad, subrhombic and of intense burnished 

 cupreous color throughout, the legs, under surface and beak also cupreous, 

 the last black at tip; beak (c 71 ) distinctly shorter than the prothorax, thick, 

 very feebly arcuate, not separated by an impression, not coarsely but deeply, 

 rather closely punctate; interocular impression shallow but evident, or ( 9 ) 

 longer, as long as the head and prothorax, similar in form and sculpture; 

 antennae submedial in both sexes, the funicle thick and more parallel than 

 usual, the joints moderately foveate, more slender in the female; club 

 gradually acutely and rectilinearly conical from near the base; prothorax 

 strongly, evenly convex in profile, the sides strongly arcuate, gradually less 

 so basally but not parallel, the tubulation moderate, subequal in the sexes; 

 punctures very minute and sparse throughout, but coarse along the basal 

 margin, especially along the broadly rounded lobe, also more distinct in the 

 constriction at the base of the tubulation; scutellum triangular, punctulate, 

 only moderately transverse; elytra about as long as wide, obtusely parabolic, 

 the humeral prominences much less conspicuous than usual; striae fine but 

 acute, distinctly punctate, the sutural not coarser but more coarsely punctate 

 basally, not at all as in the preceding; pygidium moderate, rather finely but 

 deeply punctate; male abdomen deeply impressed medio-basally, the fifth 

 segment with a deep subquadrate fusco-pubescent fovea; entire under surface 

 somewhat strongly but sparsely punctate; anterior coxae separated by rather 

 more than their width, the posterior lobe more narrowly, deeply canalate. 

 Length 5.5-6.0 mm.; width 3.75-4.0 mm. Brazil (Santarem). Four speci- 

 mens laetus n. sp. 



Body still smaller and more narrowly rhombic-oval, with polished, less intense 

 cupreous lustre, suffused with greenish, the legs and beak similar in color; 

 beak (o 71 ) not darker at tip, short, thick, evenly and rather distinctly arcuate, 

 not compressed but with the sides longitudinally impressed near the base, 

 four-fifths as long as the prothorax, separated by a feeble impression and 

 finely, sparsely punctate; antennae submedial, the funicle gradually thick-
