70 Memoirs on the Coleoptera 



ii — Pronotum strongly punctured throughout the subtubulate apex, but not 

 definitely at the sides. Body stout, almost evenly and broadly oval; beak 

 (o 71 ) moderately thick and tapering, arcuate, compressed, two-thirds as long 

 as the prothorax, closely punctured throughout, more finely above, the 

 reentrant angle between beak and front deep; antennal club smaller than in 

 the preceding forms, oval, about as long as the preceding four joints, the basal 

 funicular joint rather long and thick as usual; prothorax in upper profile 

 very evenly arcuate, a fifth wider than long, the strongly converging sides 

 evenly arcuate to the subtubulate apex, which is rather more than a third 

 as wide as the base; the usual sparse infinitesimal punctures become rather 

 evident toward the sides; basal lobe well developed, obtusely rounded, 

 with a very small feeble apical sinus, minutely, sparsely punctulate; scutel- 

 lum moderate, quadrate, not deeply impressed; elytra broadly oval, barely 

 longer than wide, evenly rounded at tip, a fifth wider than the prothorax, 

 the humeri slightly prominent, their summits rather narrowly rounded ; discal 

 striae very fine, feeble and barely traceable, I, 9 and 10 coarse and more or 

 less deep; mes-epimera with a few strong punctures near the upper limit, 

 elsewhere minutely and remotely punctulate; hind tibiae with a large tri- 

 angular external tooth at base, the proximal slope of which is finely sinuate 

 at the middle; tumid first ventral impressed at the middle. Length 3.75 

 mm.; width 2.8 mm. Brazil (Chapada — campo). November. One 

 example ovoideus n. sp. 



Pronotum rather coarsely, sparsely punctate at the extreme sides, but subim- 

 punctate at apex; body smaller in size 12 



12 — Body subevenly oval, but more attenuate behind; beak (o 71 ) thick, scarcely 

 compressed and with the punctures somewhat coarse though sparse, minute 

 and remote above, very minute and few in number on the head, except at 

 base, fully four-fifths as long as the prothorax; antennal club as long as the 

 five preceding joints, the first funicular shorter than usual; prothorax above 

 evenly arcuate in lateral profile, subsinuously sloping very near the apex, 

 almost a third wider than long, the converging sides moderately arcuate, 

 gradually a little more so and somewhat more converging beyond about the 

 middle, the apex broader than usual, rather tubulate and more than two- 

 fifths as wide as the base; lateral punctures coarse, not continuous down 

 the inferior flanks; basal lobe moderate, narrowly sinuato-truncate, subim- 

 punctate, with rather large but feeble lateral impressions; scutellum a little 

 wider than long, suboval, nearly flat and smooth; elytra but little longer 

 than wide, a sixth wider than the prothorax, ogival, with narrowly and 

 strongly rounded apex, the humeri broadly rounded, scarcely prominent; 

 discal striae subobsolete, barely traceable, those near the sutural and on the 

 flanks rather more obvious, 1, 9 and 10 deep; hind femora finely, sparsely 

 punctate, the tibiae externally oblique basally, the tooth rather small, tri- 

 angular, the inner margin serrulate ; mes-epimera coarsely, sparsely and equally 

 punctate throughout. Length 3.25 mm.; width 2.25 mm. Brazil (San- 

 tarem). One specimen definitus n. sp. 



Body nearly similar but narrower and much smaller, the beak (d 71 ) not so thick 

 and with the moderate punctures much denser; prothorax nearly similar in 

 form and profile, but scarcely a fifth wider than long, the sides more evenly 

 arcuate, barely visibly more arcuate anteriad; strong, sparse lateral punc- 

 tures visible only at the more extreme sides, but continuous down the in- 

 ferior flanks; basal lobe moderate, narrowly truncate at tip and with a few 

 small punctures; scutellum smaller, flatter, quadrate, barely as wide as 

 long; elytra with subobsolete striation, the sutural stria alone deep, 2, 9 

 and 10 fine but rather evident; mes-epimera coarsely, loosely punctate 

 throughout; legs much shorter and thinner, the hind tibiae obliquely trun-
