286 Memoirs on the Coleoptera 



shorter; surface somewhat less shining, the pronotum feebly alutaceous; 

 beak (o 71 ) very much more slender, moderately arcuate and longer than 

 the prothorax, closely puhctulate; antennae beyond the middle, longer than 

 in smithi, the funicle relatively less narrowed toward base; prothorax nearly 

 as long as wide, the sides parallel and straight to about the middle, thence 

 rounding and distinctly oblique to the apex; punctures scarcely coarse and 

 separated by about twice their diameters; scutellum closely squamulose; 

 elytra evenly elliptic, a third longer than wide, slightly wider than the pro- 

 thorax and evidently less than twice as long; grooves abrupt and deep, 

 more than half as wide as the intervals, the punctures of which are rather 

 strong, well separated and in even single series; male abdomen rather 

 broadly and distinctly impressed medio-basally, but scarcely at all less 

 clothed, the entire abdominal vestiture composed of narrower and sparser 

 squamules than usual. Length 2.1 mm.; width 0.75 mm. Brazil (Santa- 



rem). One example sodalis n. sp. 



13 — Elytra (cf ) more elongate, twice as long as the prothorax 14 



Elytra (cf) evidently less than twice as long as the prothorax 15 



14 — Body elongate-oval, black, with piceo-rufous elytra; vestiture uniform in 

 color, whitish, the squamules of the pronotum fine, moderately sparse and 

 not very conspicuous, very even on the elytra, somewhat larger but moderate, 

 loosely confused, but forming single lines laterally and posteriorly, wider 

 and moderately dense on the under surface; scutellum very densely squa- 

 mose; beak (cf) thick, compressed, finely sculptured, dull and feebly squam- 

 ulose, about as long as the prothorax and feebly arcuate, the antennae piceous, 

 near three-fifths; prothorax about as long as wide, the sides subparallel, 

 gradually rounding and more oblique anteriorly, the punctures strong, deep 

 and not quite contiguous, with a narrow partial impunctate line; elytra a 

 third to nearly half longer than wide, elongate-elliptic, slightly wider than 

 the prothorax; grooves deep and abrupt, the intervals finely, loosely punc- 

 tate, subcrenulate at the sides basally; male abdomen with the impression 

 along the middle basally rather deep and less squamose; anterior femora 

 normal. Length 2.35-2.45 mm.; width 0.9-1.0 mm. Brazil (Rio de 



Janeiro). November. Three male examples australis n. sp. 



Body a little broader, suboval, more parallel than in australis, black, with obscure 

 piceous elytra; vestiture whitish, coarser and closer than in the preceding, 

 denser beneath, similarly arranged but more conspicuous on the elytra, the 

 scutellum similarly abruptly and very densely albido-squamose; beak (d 1 ) 

 almost similar, but not quite so thick, feebly arcuate and as long as the 

 prothorax, the antennae near three-fifths; prothorax very slightly though 

 evidently wider than long, the sides broadly and evenly arcuate, becoming 

 gradually straight and parallel in basal half; punctures not quite so deep or 

 strong as in the preceding, very close-set, the median smooth line scarcely 

 apparent; elytra elongate-elliptic, almost one-half longer than wide, slightly 

 wider than the prothorax, the grooves deep and abrupt, but not quite so 

 coarse, the intervals even and with loosely confused small punctures; they 

 are a little wider than in australis; anterior femora clavate and rapidly 

 pedunculate at base in the type; male abdomen very much more densely 

 clothed with larger scales, the medio-basal impression feeble and not dis- 

 tinctly less squamose. Length 2.4 mm.; width 0.9 mm. Brazil (Chapada). 



May. A single male suffusus n. sp. 



15 — Form oval, moderately narrow, convex as usual, black, the elytra scarcely 

 less so; vestiture almost as in the preceding, except that the pronotal squam- 

 ules, though similarly uniform and rather abundunt, are shorter, finer and less 

 conspicuous, and that, on the under surface, they are dense on the prosternum, 

 met-episterna and abdomen, but elsewhere rather well separated; beak (o 71 )
