Brazilian Barin.e 97 



mm.; width 1.8-2.0 mm. Brazil (Chapada — forest and campo). Novem- 

 ber and December. Five specimens convexicollis n. sp. 



Body smaller and especially narrower than in the preceding, though nearly 

 similar in color, lustre, sculpture and vestiture, the metasternum similarly 

 more closely squamulose than the side-pieces; beak nearly similar but 

 slightly shorter, slender, arcuate and cylindric, smoother and more shining; 

 eyes separated by the full width of the beak; prothorax less transverse, only 

 a fourth wider than long, the arcuate sides less rapidly converging anteriad, 

 more parallel and feebly arcuate in about basal half; apex not quite so wide, 

 but more than half as wide as the base; sculpture and lobe nearly similar, 

 except that the punctures are in mutual contact; elytra nearly similar, the 

 feebly arcuate sides a little more oblique and the apex less broadly rounded, 

 rather more evidently wider than the prothorax, the grooves, punctures 

 and scanty vestiture almost similar. Length 3.35-3-85 mm.; width 1 4-1.7 

 mm. Brazil (Chapada). May. Two specimens, found on flowers in 

 clearings balteella n. sp. 



Body a little narrower and more suboval than in convexicollis, nearly as in balteella, 

 but more abbreviated, similar in color, lustre and vestiture but differing 

 from either in the less coarse thoracic punctures, which are more distinctly 

 separated among themselves, especially near base, where they become small 

 and widely separated; the basal lobe also has a broad shallow apical sinus, 

 invisible in either of the preceding; beak closely sculptured, feebly arcuate, 

 distinctly shorter than the prothorax ( 9 ), still a little shorter and less 

 slender (d"); eyes separated by not quite the rostral width; head rather 

 finely, very densely punctured throughout; prothorax still less transverse 

 than in balteella, a fifth wider than long, rather more in the female, the sides 

 broadly rounded medially, oblique anteriorly, nearly parallel basally, the 

 truncate apex three-fifths as wide as the base; elytra nearly similar, somewhat 

 more than one-half longer than the prothorax, the strial intervals a trifle 

 wider. Length 3.9-4.0 mm.; width 1.8 mm. Brazil (Santarem). Two 

 specimens thoracica n. sp. 



I am unable to identify these species with any of those described 

 as Ccelonertus by Solari, all of which may truly belong to Ccelonertus, 

 as the prothorax is very much more elongate than in any one of 

 the five preceding species, and the form is more cylindric, except 

 perhaps in alternatus and baridioides; they are also from rather 

 widely different localities. 



Ccelonertus Solari 



In this genus the body becomes narrower and more truly parallel 

 and cylindric, with the prothorax longer as a rule. The antennal 

 club differs radically, for, instead of being very solid, with fine and 

 feebly marked sutures and short basal segment, it is here more 

 abbreviated, less densely pubescent, with deep coarse sutures and 

 relatively very large basal segment. There seem to be two rather 

 well defined species at hand as follows : 



Form almost cylindric and parallel, only feebly shining, black throughout; pro- 

 notal punctures bearing slender sparse white squamules, a little broader and 

 closer at the sides; elytra with single series of small dark brown squamules,
