120 Memoirs on the Coleoptera 



moderately arcuate sides and rather strongly rounded apex, at the humeri 

 but little more than a sixth wider than the prothorax, fully four-fifths longer; 

 striae fine and almost completely obsolete, feebly punctulate, gradually 

 stronger and more punctate, though not definitely groove-like, laterally, 2 

 and 3 slightly dilated and deep at base; punctures on the thoracic flanks 

 below much finer and sparser; male with a more deeply impressed and more 

 squamulose basal abdominal impression and very short, slender and erect 

 prosternal processes; hind femoral punctures sparse. Length 6.5 mm.; 

 width 4.2 mm. Brazil (Rio de Janeiro). October. One specimen. 



vitrarius n. sp. 



19 — Elytral strise fine and feeble, sometimes virtually obsolete 20 



Elytral strise deep, sharply abrupt and groove-like 21 



20 — Antennal funicle with the first two joints elongate, as in the three preceding 

 species; elytral striae rather impressed. Form not very stout, rhomboid- 

 oval; beak moderately thick and arcuate, rather closely, strongly sculptured, 

 a little longer than the head and prothorax; antennae medial, not very 

 slender, blackish, the first funicular joint longer and thicker than the second, 

 the third slightly longer than wide, the club rather longer than the preceding 

 four joints; prothorax two-fifths wider than long, slightly more convex 

 basally, the arcuate sides subparallel in less than basal half, the tubulation 

 almost three-sevenths as wide as the base; basal lobe smooth, broadly 

 rounded, impressed medially at apex, the lateral impressions evident; scu- 

 tellum transversely subquadrate; elytra somewhat longer than wide, evenly 

 parabolic, with moderately prominent humeri, two-thirds longer than the 

 prothorax; striae fine but broadly and feebly impressed, finely, distinctly 

 punctate; femora strongly, loosely punctate; prosternum glabrous, with 

 large deep canal; metasternum with a striiform sulcus; first abdominal 

 segment broadly, feebly impressed and with rather close setulose punctures 

 at the middle. Length 5.5 mm.; width 3.4 mm. Brazil (Rio de Janeiro). 

 November. One specimen, the abdominal characters of which would seem to 

 indicate the male, but without trace of the prosternal spines of the preceding 



group, or of the following species inops n. sp. 



Antennal funicle very unlike that in any of the preceding species, the first joint 

 being the only one elongated, the second obconic and but little longer than 

 wide. Very broadly rhomboidal and smooth; beak thick, strongly arcuate, 

 as long as the head and prothorax, finely, sparsely punctate throughout, even 

 at the scarcely compressed sides basally; antennae rather thick and short, 

 black, the seventh funicular joint wider, the club longer than the preceding 

 four joints; prothorax three-fifths wider than long, the strongly and evenly 

 arcuate sides gradually parallel basally; tubulation with only very minute 

 and remote punctulation, rather over a third as wide as the base, the basal 

 lobe smooth, broadly impresso-sinuate at apex, the lateral impressions dis- 

 tinct, scutellum transversely quadrate; elytra not quite as long as wide, 

 almost a third wider than the prothorax and four-fifths longer, parabolic, 

 with feebly biundulated flanks and very prominent humeri; striae very fine 

 and feeble, subobsolete, the punctures not distinct, 2-4 briefly dilated at 

 base, the sutural moderate, deeper and punctate basally; legs rather short 

 and stout, the femora sparsely and not very strongly punctate; male with 

 the abdomen flat, minutely and remotely punctulate medio-basally, the 

 ante-coxal spines of the prosternum moderate, feebly arcuate and vertical. 

 Length 6.65-6.8 mm.; width 5.0-5.2 mm. Brazil (Espirito Santo and Rio 



de Janeiro). Two male specimens decens n. sp. 



21 — Pronotum smooth or nearly so at base, as usual 22 



Pronotum punctured and squamulose along the base, especially on the basal 

 lobe, the scutellum punctulate but glabrous; first two joints of the antennal 

 funicle much elongated and equal 3 2
