Brazilian Barin/e 229 



and closely decumbent scales as here, but of less decumbent, very 

 fine and hair-like squamules. The species of Brachygerceus at pres- 

 ent known are the following: 



Pattern of ornamentation somewhat as in Centrinaspis graphica, being solid 

 areas of white scales on a black background; presternum bispinose in the 

 male 2 



Pattern simple, the scales dense and almost uniform nearly as in Centrinaspis 

 condensata; presternum unarmed in the male 3 



2 — Form oblong-ovoidal, black, the legs and beak dull rufous; pronotum with 

 the dense white scales forming a parallel sublateral quadrate spot in basal 

 half, also with some less dense and less decumbent along the apex and entire 

 median line, the dense white scales of the elytra forming a semicircular scutellar 

 spot, and, on each elytron, a solid quadrate spot behind the middle on intervals 

 2-4 and separated from the scutellar area by nearly twice their length; 

 sides with looser white squamules; entire under surface with very dense 

 white scales; beak in both sexes rather thin, smooth, moderately and evenly 

 arcuate, gradually slightly thicker at base and about as long as the elytra, 

 the antennae slender, rufous, medial ( 9), a little beyond (cf), the first two 

 funicular joints very long and equal, the club abrupt, oval, subequally 

 divided by the distinct sutures; prothorax rather short, one-half wider than 

 long, the strongly arcuate sides becoming subparallel basally; apex scarcely 

 at all tubulate and less than half as wide as the base; punctures coarse and 

 dense; scutellum small, glabrous and impressed; elytra parabolic, somewhat 

 narrowly rounded at tip, rather over a fourth longer than wide, about twice 

 as long as the prothorax; grooves rather coarse and deep; fine dark squam- 

 ules nearly black; male with the abdomen feebly impressed and a little less 

 squamose at base, the presternum with two very slender erect processes, 

 scarcely one-half as long as the prothorax and widely separated, the inter- 

 vening surface flat and not at all modified. Length 3.2-3.4 mm.; width 

 I -55 _I -7 mm - Brazil (Santarem). Three specimens bellulus n. sp. 



Form, ornamentation and general structure almost similar, but the discal white 

 areas of the elytra are larger and are separated from the large scutellar 

 region by only half their length; beak (9) nearly similar but longer, dis- 

 tinctly exceeding the elytra, the antennae similar; prothorax nearly similar 

 but with the sides less inflated, being convergent, evenly and much more 

 feebly arcuate from base to apex; parabolic elytra almost similar but shorter, 

 with even more narrowly rounded apex and similarly reentrant sutural 

 angle, not quite twice as long as the prothorax. Length 3.3 mm.; width 

 1.7 mm. Brazil (Chapada — campo). October. One female example. 



pergratus n. sp. 



3 — Body rather stout, ovoidal, black, with dull rufous legs and apical part of the 

 beak; scales above parallel and rather wide, not extremely dense, being 

 narrowly separated as a rule, uniform brownish-white in color, those of the 

 pronotum often fulvescent except laterally; they are wider, very dense and 

 white throughout beneath; beak (o 71 ) evenly and moderately arcuate, rather 

 thick, scarcely as long as the head and prothorax, sparsely punctate, squam- 

 ulose at the extreme base, or ( 9 ) more slender, longer, evidently longer than 

 the head and prothorax, strongly arcuate basally but thence almost straight 

 to the apex; antennae slender, rufous, medial ( 9 ) or distinctly beyond (0*); 

 first funicular joint as long as the next two, the second relatively much shorter 

 than in the two preceding; prothorax short, one-half to three-fifths wider 

 than long, inflated, the sides strongly arcuate, becoming subparallel basally; 

 apex slightly ( 9 ) or much (o 71 ) less than half as wide as the base; punctures
