Brazilian Baring 395 



Body somewhat as in the preceding, the color, lustre and sculpture almost similar, 

 the size smaller, the subapical angulation of the prothorax much less con- 

 spicuous and more obtuse, the antero-lateral concavity of the surface much 

 less pronounced; beak thick, arcuate, as long as the head and prothorax, 

 the antenna medial; prothorax similarly convex, not quite so transverse 

 the parallel sides a little more arcuate, the tubulation relatively wider, halt 

 as wide as the base; surface similarly smooth and with a regular line oi 

 punctures along the basal margin as in the preceding; elytra nearly similar, 

 the pygidium not so transverse, similarly densely punctate; under surface 

 almost similar. Length 34 mm.; width 1.75 mm. Brazil (Santarem).

4 _ Fo rm color and sculpture-^ther than that of the elytra— nearly as in the 

 two preceding; beak similarly sculptured and arcuate but longer and a 

 little less thick, somewhat longer than the head and prothorax, the antennae 

 behind the middle; prothorax not quite so convex— viewed in profile, scarcely 

 more than a third wider than long, the parallel sides distinctly arcuate, the 

 subapical angle rather more obtuse when viewed from above, the tubulation 

 narrower, much less than half as wide as the base, the head smaller; surface 

 less smooth, sparsely, finely punctulate at apex and near the sides the lateral 

 rugulosity rather more pronounced; descending antero-lateral ridge de- 

 limiting the concavity much more pronounced than in amnicola, and even 

 more prominent than in truncatidens ; basal line of punctures similar; scu- 

 tellum similarly triangular, but more minute; elytra nearly similar in form 

 and relationship, but quite different in sculpture, the surface with more 

 evident minute punctulation laterally; pygidium nearly similar but more 

 finely punctate; under surface nearly as in the two preceding, the legs 

 shorter Length 3.15 mm.; width 1.7 mm. Brazd (Santarem). One

5 _ Fe moral tooth distinct; strial intervals smooth or nearly so; prothorax not 

 wider than the elytra ■ '.'''.',' ' ' 1 * ' ' + i 



Femoral tooth very minute; strial intervals coarsely, unisenally punctate the 

 punctures obsolete toward the suture; prothorax more inflated, slightly 

 wider than the elytra 



6— Prothorax about as wide as the elytra 7 



Prothorax evidently narrower than the elytra 



7-Integuments shining, glabrous, black, the prothorax very faintly picescent; 

 beak rather short, not quite as long as the prothorax, feebly and gradually 

 tapering evenly arcuate, somewhat strongly but loosely punctate the 

 antenna, a little behind the middle; prothorax two-fifths wider than long 

 the sides strongly, subevenly arcuate, gradually less so and parallel behind 

 the middle; tubulation short, feebly sinuate medially, not quite half as wide 

 as the base; surface smooth, minutely punctulate, longitudinally rugulose 

 at the sides, the basal series as usual; scutellum small, ogival; elytra scarcely 

 a fifth longer than wide, the oblique sides nearly straight, the apex rapidly 

 and somewhat broadly obtuse, one-half longer than the prothorax; grooves 

 sharply marked throughout, exarate apically; intervals smooth feebly 

 punctulate laterally; pygidium small, almost flat, densely punctate and 

 semicircular; metasternum very coarsely, perforately punctate; legs rather 

 short. Length 3.0 mm.; width 1.65 mm. Brazil (Chapada) March.
