Brazilian Baring 427 



tellum nearly similar; elytra as in the preceding in outline and proportions, 

 the striae still finer and feebler, finely but evidently, distantly punctate; 

 pygidium nearly similar, one-half wider than long, circularly rounded and 

 rather strongly but loosely punctate; punctures beneath only moderately 

 coarse, well separated, the abdomen subimpunctate medially. Length 3.85 

 mm.; width 2.5 mm. Brazil (Santarem). A single female specimen. 



incerta n. sp. 



4 — Body moderately broad, very convex, polished, green, with cupreo- aeneous 

 suffusion by particularly reflected light, especially beneath and on the legs 

 and beak, the last (<f) nearly straight, three-fifths as long as the prothorax, 

 distinctly and not very closely punctate, the antennae nearly at two-thirds; 

 . prothorax in profile very convex, declivous anteriad, two-thirds wider than 

 long, the parallel sides feebly arcuate, rapidly rounding but not angulate 

 near two-thirds and thence very oblique and nearly straight to the short, 

 feeble tubulation, which is scarcely three-sevenths as wide as the base; 

 punctures coarse but well separated apically, gradually less coarse thence 

 posteriorly as usual, without trace of a smooth median line; along the base 

 the punctures are rather coarse, close and confused, the lobe truncate, the 

 scutellum smaller, more closely punctulate and but little wider than long; 

 elytra in outline and proportions nearly as in the two preceding, the striae 

 fine but stronger, coarser at base and apex and with strong, though not in 

 any way coarse punctures, the intervals sparsely and infinitesimally punctate; 

 pygidium formed as usual but rather convex; male abdomen nearly as in 

 angulata, the two small foveae of the fifth ventral still more approximate. 

 Length 3.7 mm.; width 2.2 mm. Brazil (Chapada). November. One 

 specimen obliqua n. sp. 



Body much broader, polished, bright green, more or less suffused with cupreous 

 beneath and often also above, similarly very convex anteriorly and declivous 

 toward the thoracic apex; beak (c?) very short and thick, rather finely, 

 moderately closely punctate, almost straight and three-fifths as long as the 

 prothorax, or ( 9 ) a little less thick, more bent at apex and two-thirds as 

 long as the prothorax, the latter fully four-fifths wider than long, the sides 

 parallel and straight for three-fifths, then rapidly rounding, becoming very 

 oblique to the very gradual, short and feeble tubulation, whiah is about two- 

 fifths as wide as the base; punctuation nearly as in the preceding, the basal 

 lobe evenly rounded, not truncate, the scutellum similar but larger, closely 

 punctulate; elytra similar in general form and proportion, the striae and 

 punctuation nearly similar but somewhat finer; metasternum and medio- 

 basal part of the male abdomen distinctly impressed and smooth, the two 

 small discal foveae of the fifth segment similar but very approximate. Length 

 3.85-3.9 mm.; width 2.6-2.65 mm. Brazil (Santarem). Four specimens. 



recticollis n. sp. 



5 — Form oblong-oval, strongly convex, polished and subaeneous-green, somewhat 

 cupreous beneath, the legs and beak green; beak (9) very short, thick, 

 slightly arcuate, finely, loosely punctate and only three-fifths as long as the 

 prothorax, the latter strongly, subevenly convex in profile, only one-half 

 wider than long, the sides distinctly converging, evenly and very feebly 

 arcuate, gradually rounding anteriorly to the short and gradual, feeble but 

 unusually wide tubulation, which is almost half as wide as the base; punc- 

 tures coarse, deep and separated by barely their diameters laterally and 

 apically, becoming fine and sparse medio-basally and with a distinct narrow 

 impunctate line; basal lobe evenly rounded, the scutellum ogival, punctulate, 

 only a little wider than long; elytra but little longer than wide, distinctly 

 wider than the prothorax and barely more than one-half longer, evenly and 

 obtusely parabolic in form, the humeral prominences more developed than
