Brazilian Baring 257 



the inner; dense squamose areas of the under surface as in cuneipennis, except 

 that the outer tip of the strongly and densely punctate mes-epimera is also 

 squamose; upper surface slightly ascending anteriorly viewed in profile, the 

 beak (cf) unusually long, a third longer than the elytra in fully developed 

 stages, rather thick, strongly and sparsely punctate, gradually narrow and 

 smooth in about apical fourth; antennae rather long, just beyond two-thirds, 

 the long and slender scape piceo-rufous; prothorax with the sides broadly, 

 subevenly arcuate, becoming parallel near base, the strong tubulation with 

 numerous rather small punctures; basal margin punctate and furrowed, the 

 lobe small, obtuse; scutellum distinctly transverse; elytra triangular, nearly 

 a third longer than wide, fully a fifth wider than the prothorax and about 

 three-fifths longer, the grooves moderate, deep and smooth, punctured 

 laterally; male with a large and feebly impressed flat, slightly transverse 

 oval area occupying the entire median part of the first segment, and densely 

 clothed with narrow yellowish subherissate scales, the second segment with 

 a very small anterior area, clothed more sparsely with more hair-like squam- 

 ules of the same color; prosternal spines in the type unusually developed, 

 subporrect, slightly curved and fully three-fourths as long as the prothorax, 

 much shorter in less developed stages, the glabrous canal deep, becoming 

 very deeply excavated posteriorly. Length 5.0-5.35 mm.; width 2.6-2.75 

 mm. Brazil (Chapada). October and December. Two male specimens. 



chapadanus n. sp. 



Prothorax black, very nearly as long as wide; body almost as in the preceding 

 throughout, but a little smaller and narrower, and with the infinitesimal 

 punctures of the upper surface almost obsolete, the sides of the prothorax 

 somewhat more arcuate, the tubulate apex slightly wider in the male, the 

 base nearly similar; scutellum smaller and much less transverse; elytra 

 nearly similar, but not so long, the outer squamose line distinctly less than 

 half as long as the inner; under surface nearly similar, except that there are 

 no pale scales on the mes-epimera, which, similarly, are visible from above; 

 beak nearly similar but shorter, only a little longer than the elytra, the anten- 

 nal scape black; male with almost similar sexual characters but with much less 

 developed prosternal spines, varying from very short to less than half as 

 long as the prothorax. Length 4.8-5.0 mm.; width 2.25-2.3 mm. Brazil 

 (Santarem). Seven specimens mimus n. sp. 



7 — Form, lustre, coloration and ornamentation very much as in chapadanus and 

 mimus, but with shorter elytra; minute and remote punctulation evident, 

 more distinct, close and subrugose at the extreme pronotal sides basally; 

 beak (o 71 ) nearly a third longer than the elytra, not very slender and much 

 more coarsely and closely punctured than in the two preceding, rather 

 rapidly but not abruptly narrowed and smoother in but little over apical 

 fourth; antennae near apical third, long, black, the first funicular joint rather 

 long, the outer joints gradually wider to the width of the club; prothorax (cf ) 

 as long as wide, the sides broadly, subevenly arcuate; tubulation long; base 

 as in the preceding; scutellum small, quadrate, not at all transverse; elytra 

 but little over a fourth longer than wide, a fifth wider than the prothorax 

 and only one-half longer, triangular, with slightly coarser but otherwise 

 similar grooves, the inner densely squamose line extending almost three- 

 fourths, the outer slightly less than half as long as the inner; squamose areas 

 of the under surface as in chapadanus, except that the sides of the first 

 ventral are also squamose to some extent; male with the median part of 

 the first ventral flattened, the squamose area smaller than in chapadanus 

 and mimus, and composed of broader, denser and more closely decumbent 

 scales, the second segment not at all squamulose and with a few minute 

 punctures, the presternum nearly similar. Length 5.0 mm.; width 2.45 mm.
