distinctly beyond the middle (cf ) or near two-fifths ( 9 ), the scape 

 virtually attaining the eye, long in the male, the first funicular 

 joint as long as the next two, 2-7 short, compact, transverse and 

 gradually increasing in width, the club large, oval, densely pubescent 

 throughout, as long as the preceding six joints, at least in the male, 

 and subequally divided by the deep and conspicuous sutures. The 

 prosternum is large and with even surface, remotely separating the 

 coxae and wholly unarmed in the male. The legs are moderate, the 

 femora somewhat inflated, the anterior not longer in the male but 

 with more strongly inflated femora, with or without a blunt oblique 

 asexual inferior tooth in both sexes, the tarsal claws moderate 

 and divergent. The prothorax is feebly tubulate, the basal lobe 

 very short and evenly rounded, the scutellum well developed, flat, 

 transversely suboval, free at the sides but in close contact with the 

 elytra behind; elytra with the grooves much diminishing in strength 

 internally, as in the preceding genus. The species at hand are 

 four in number as follows : 



Anterior femora with an oblique truncate tooth beneath in both sexes 2 



Anterior femora with the lower margin of the inflation angularly dentiform.. . .3 



Anterior femora strongly medially swollen, but not at all dentate beneath 4 



2 — Body parallel, feebly convex, with feebly tumid humeri, somewhat more 

 abbreviated in the female, deep black throughout, polished and glabrous; 

 beak (cf) thick, feebly arcuate, compressed, finely, loosely punctate and 

 much shorter than the prothorax, or ( 9 ) longer, slender, cylindric, smooth, 

 dilated, compressed and with the flat sides impressed behind the antennae, 

 a little longer than the prothorax; piceous antennae as described above, 

 prothorax as long as wide, a little wider ( 9 ), the parallel sides straight (cf ), 

 feebly arcuate (9), rapidly rounding and converging in about apical third 

 to the tubulation, which is rather more than half as wide as the base; punc- 

 tures gradually stronger but not coarse, closer and subrugulose toward the 

 sides, finer and denser in the female; elytra somewhat more (cf) to less ( 9 ) 

 than one-half longer than wide, the sides only just visibly oblique, gradually 

 circularly rounding at apex, very little wider than the prothorax and three- 

 fourths longer; grooves coarse and exarate at apex, fine and punctulate on 

 the disk suturally and deep but not very coarse laterally; intervals smooth, 

 loosely and infinitesimally punctulate; male abdomen strongly and closely 

 punctate, more finely and densely on the last three segments, feebly impressed 

 medio-basally. Length 3.8-4.0 mm.; width 1.4-1.6 mm. Brazil (Santa- 



rem). Four specimens femoralis n. sp. 



Body broader, feebly convex, deep black and polished, feebly subcuneiform, the 

 prothorax larger; beak (cf ) nearly similar but a little longer, four-fifths as 

 long as the prothorax; antennae blackish, nearly as in the preceding; pro- 

 thorax as long as wide, the parallel sides evenly and very evidently arcuate, 

 gradually rounding in about apical third, the tubulation longer and more 

 sharply marked, not quite half as wide as the base; punctures minute and 

 sparse, gradually more distinct and longitudinally ruguliform laterally, but 

 not at all coarse, much finer than in the male of femoralis; elytra shorter, 

 less than one-half longer than wide, more broadly and obtusely rounded at 

 apex, with still more feebly marked humeral swelling, not quite as wide as 

 the prothorax and scarcely one-half longer; grooves throughout nearly
