Brazilian Baring 405 



abdominal suture not evident, but marked by a strong impression. 

 The species known to me are as follows : 



Body subevenly oval 2 



Body narrower, cuneiform 3 



2 — Body evenly oval, a little stouter, shining and deep black; beak in the type 

 and antennae as described above, the former almost as long as the head and 

 prothorax, the latter shining, black, with densely pubescent club; prothorax 

 slightly elongate, the sides feebly converging and nearly straight, very 

 gradually arcuate and more converging beyond the middle to the feeble 

 sinuses, the apex subsinuate medially and half as wide as the base; surface 

 with infinitesimal sparse punctulation, becoming fine, longitudinal ruguliform 

 lines at the sides, which are finely punctulate as in the preceding genus; 

 elytra rapidly oval or parabolic, scarcely a third longer than wide, at the 

 evidently tumid humeri very slightly wider than the prothorax, only two- 

 fifths longer, the subapical umbones very moderate; striae extremely fine 

 and subobsolete, finely punctate, impressed at apex, the intervals each with 

 a single series of infinitesimal punctules; punctures beneath diversified, 

 coarse to fine on various parts, the abdomen nearly smooth, evenly convex; 

 posterior prosternal lobe almost smooth, the anterior slope distinctly punc- 

 tate. Length 5.7 mm.; width 2.3 mm. Brazil (Santarem). One specimen. 



scrobiculata n. sp. 

 Body nearly as in the preceding but narrower, with similar humeri but more 

 prominent subapical umbones; beak in the type similar in form, but not 

 quite so long or thick, still more minutely and remotely punctulate and not 

 quite as long as the head and prothorax, the antennae similar in general plan 

 but with the funicle more slender, the club as long as the preceding six 

 joints; prothorax more distinctly elongate, the evenly converging sides 

 feebly and evenly arcuate from base to the feeble apical sinuses; apex rather 

 more than half as wide as the base; sculpture similar, the lateral punctulate 

 rugulosity still finer; scutellum smaller, more ogival and less transverse; 

 elytra narrower, more than a third longer than wide, the oblique sides 

 straighter, the apex more rapidly obtuse, barely wider than the prothorax 

 and two-fifths longer; pygidium and the evenly convex and nearly smooth 

 abdomen almost similar; posterior prosternal lobe very smooth, the anterior 

 slope sparsely punctate. Length 4.8 mm.; width 1.9 mm. Brazil (Chapada 



— campo). November. One example atrolucens n. sp. 



Body smaller, evenly elongate-oval, convex, shining, deep black; beak much 

 shorter but as long as the prothorax, relatively thicker, strongly arcuate and 

 compressed, sparsely punctulate, the upper line of the flanks acute; flattened 

 flanks longitudinally impressed, deeply sulcate beyond the antennae; an- 

 tennae black, very slightly post-median, short, the club longer than the entire 

 stem; prothorax as long as wide, the sides feebly converging and very 

 slightly arcuate, a little more rounding anteriorly, the apex fully four- 

 sevenths as wide as the base, the basal lobe much shorter and more broadly 

 rounded than in either of the preceding; punctures small but distinct, sparse, 

 forming longitudinal punctulate ruguliform lines at the sides; elytra two- 

 fifths longer than wide, oval, rather obtusely rounded at apex, not evidently 

 wider than the prothorax and about three-fifths longer, the humeral swellings 

 very feeble, the subapical umbones also feeble; striae represented by series 

 of fine punctures, impressed at apex, the interstitial punctures very small 

 but evident in single lines; pygidium as long as wide, strongly, closely 

 punctate; abdomen smooth and very evenly convex in the type. Length 

 3.85 mm.; width 1.7 mm. Brazil (Santarem). One specimen.
