Brazilian Baring 281 



the punctures of which are strong, close-set and in single series; male with 

 the extremely densely squamose abdomen very feebly impressed and with 

 slightly separated scales medio-basally. Length 3.7-4.1 mm.; width 1.65- 

 1.75 mm. Brazil (Chapada). May and November. Three specimens. 



nimius n. sp. 

 Form less broad and still more elongate, rather less convex; coloration, lustre 

 and vestiture nearly similar, except that the squamules above are pale, the 

 large and very dense scales beneath deeper, yellow, and not almost white; 

 scutellum a little larger and more quadrate; beak (c?) much longer, feebly 

 arcuate, rather less coarsely sculptured, with more numerous slender squam- 

 ules and fully as long as the head and prothorax; antennae piceous, at three- 

 fifths, the scrobes similarly very deep and only moderately oblique; obtuse 

 reentrant angle at the base of the beak evident, in nimius almost obsolete; 

 prothorax fully as long as wide, the sides parallel and nearly straight for a 

 much longer distance from the base, gradually rounding and oblique in 

 apical two-fifths; punctures sparser and not so coarse; elytra elongate, 

 suboval, relatively somewhat more obtuse at tip, nearly one-half longer than 

 wide, three-fourths longer than the prothorax, the sculpture and vestiture 

 nearly similar in form; sexual characters beneath almost similar. Length 

 3.6 mm.; width 1.45 mm. Brazil (Chapada). November. One example. 



elongatus n. sp. 



One of the males of nimius has the elytra relatively somewhat 

 shorter and more broadly rounded at apex than the other, but 

 there seems to be no other difference. 



Nicentrus Csy. 



This is a large genus, abundant almost throughout North and 

 South America, except in the Pacific coastal regions. The body 

 is elongate and more or less narrowly suboval, the humeri feebly to 

 distinctly subprominent. The beak is not very slender, strongly 

 sculptured, differing but little in the sexes, with the antennae often 

 beyond the middle in both, never separated from the head by a 

 very distinct reentrant angle and with the mandibles somewhat 

 narrow and prominent, with the straight inner margins obtusely 

 dentate medially and biemarginate. The end of the beak above 

 the mandibles is obtusely lobed, the lobe defined by sinuations or 

 even deeper fissures. Antennae moderate, the first funicular joint 

 as long as the next two or longer, the club oval, with distinct 

 sutures, the basal segment apparently always distinctly less than 

 half the mass. The presternum is not impressed, except by a 

 small feeble transverse apical fossa; it is densely squamose and 

 very moderately separates the coxae. The prothorax is not tubulate 

 at apex, the basal lobe short and gradual, the scutellum usually 

 more or less densely squamose and the elytra moderately grooved, 

 the grooves not very distinctly punctate, except in striatopunctatus. 

 The species at hand may be known as follows. 



Pronotum with three distinctly defined pale squamose vittae, the strial intervals 

 with uniseriate, or sometimes in small part narrowly confused, squamules, 

 the series in many cases abbreviated 2
