304 Memoirs on the Coleoptera 



base, nearly as long as the head and prothorax, the antennae slender, piceous, 

 the club and enlarged seventh funicular joint finely, densely pubescent; 

 prothorax a fourth wider than long, the feebly arcuate sides more rapidly 

 rounding in apical fourth, the apex half as wide as the base; punctures 

 coarse, deep, separated by less than their widths, with a narrow smooth line 

 centrally; scutellum larger, longer than wide, deeply impressed; elytra in 

 outline nearly as in the preceding but only three-fourths longer than the 

 prothorax and slightly, though evidently, wider; grooves and intervals 

 similar in proportion, but the punctures of the latter are very different, 

 being small, rounded and isolated, sparsely confused; abdomen rather closely 

 punctulate and conspicuously squamose. Length 5.0 mm.; width 2.23 mm. 

 Brazil (Chapada). June. One specimen sospes n. sp. 



Prothorax not inflated, the subparallel sides never more than just visibly arcuate; 

 vestiture white, consisting of fine, short, sparse and more or less inconspicuous 

 squamules above 2 



2 — Body notably stout, oblong, convex, shining and deep black throughout; 

 sparse white squamules above very much shorter than in the preceding two 

 species, but not very slender and distinct, short and well separated beneath, 

 closer on the met-episterna, especially at apex and base; beak ( 9 ) shorter, 

 as long as the prothorax, rather slender, very feebly arcuate, cylindric, the 

 sculpture nearly as in the preceding, but less dense and less squamulose at 

 base; antennae slender, medial, blackish, the first funicular joint somewhat 

 longer, equal to the next three; prothorax not quite a third wider than long, 

 the sides rapidly rounding in apical fourth, the apex rather more than half 

 as wide as the base; punctures somewhat coarse, very deep, separated by 

 about half their diameters, with a narrow but entire median smooth line; 

 scutellum shorter and broader, subquadrate, very deeply and smoothly con- 

 cave; elytra only a third longer than wide, the sides parallel and feebly arcuate, 

 rapidly rounding behind through the very broadly and obtusely rounded 

 apex, slightly wider than the prothorax and four-fifths longer; grooves a 

 third as wide as the intervals, which are finely, loosely and subasperately 

 subpunctate, the punctures not rounded or distinctly defined; abdomen 

 rather closely but not coarsely punctate. Length 5.2 mm.; width 2.5 mm. 

 Brazil (Chapada). June. A single female obtusus n. sp. 



Body less stout, oblong-suboval, strongly convex, deep black and shining through- 

 out, the white squamules above very fine and sparse throughout, less conspicu- 

 ous though as usual broader but well separated beneath, a little larger and 

 closer evenly throughout the met-episterna; beak (cf ) rather stout, but evenly 

 cylindric, feebly arcuate, three-fourths as long as the prothorax, finely, 

 loosely punctulate and remotely squamulose; antennae slender, blackish, 

 sometimes with rufous scape, inserted at four-sevenths; prothorax only a 

 fifth wider than long, the sides somewhat as in the preceding, but more 

 gradually rounding anteriorly; apex half as wide as the base; punctures 

 less coarse and separated by one-half more than their diameters, with similar 

 smooth line; scutellum smaller, less concave and more obtrapezoidal; elytra 

 nearly one-half longer than wide, less obtuse, subevenly and semicircularly 

 rounded behind, subparallel at the sides, very slightly wider than the pro- 

 thorax and fully three-fourths longer; grooves and intervals nearly similar, 

 the interstitial punctures however very fine, sparsely confused, but individ- 

 ually distinct; male abdomen closely punctured, with a rather deep impres- 

 sion medially toward base; prosternal spines subporrect, half to three-fourths 

 as long as the prothorax in the types. Length 4.6-5.0 mm.; width 2.1-2.2 

 mm. Brazil (Chapada). November. Two male specimens, spinifer n. sp. 



Body still less stout, elongate-suboval, deep black and rather shining throughout, 

 the whitish squamules above very remote, much shorter, more slender and
