Brazilian Baring 23 



clothed. Length (d*) 8.3 mm.; width 4.8 mm. Brazil (Chapada). Sep- 

 tember subsimilis n. sp. 



5 — Antennal club rapidly and sharply conical, its basal segment broad and barely a 

 third the total length; scutellum not grooved. Body rather broadly rhombic 

 in form, convex, black, the dense linear fulvous scales above with three elon- 

 gate black denuded spaces at each side of the pronotum, two near the strong 

 median carina and one antero-lateral; on the elytra the black denudation 

 forms very irregular broken fasciae or sometimes isolated smaller spots; 

 linear scales of the under surface scarcely paler and not quite so dense, with 

 the prothorax denuded throughout the width at base, the squamules sparse 

 on the met-episterna except at apex and base; large basal abdominal im- 

 pression more distinct and subdenuded in the male; beak similar in the sexes, 

 rather thick, a little longer than the head and prothorax, densely sculptured, 

 costulose and squamose, becoming smooth, subdenuded and finely punctate 

 distally; antennae slightly beyond the middle, moderate in length; prothorax 

 two-fifths wider than long, the sides strongly converging and broadly, evenly 

 arcuate from the base; apex two-fifths as wide as the base; punctures dense; 

 scutellum transverse, trapezoidal, the middle of the apex acicularly pro- 

 longed; elytra ogival, two-fifths wider than the prothorax, the apex more 

 obtuse than in the two preceding, the humeri similar; striae coarser, deep, 

 obscurely punctate; intervals and legs almost similar. Length (o 7| 9) 

 7.0-8.0 mm.; width 4.0-4.8 mm. Brazil (Chapada). February. Seven 

 specimens variegata n. sp. 



Antennal club oval, not broadest basally; scutellum grooved along the middle. . .6 



6 — Body not very broadly rhombic, moderately convex, black, with small dense 

 lineiform scales above, fulvous in color but partially denuded in an elongate 

 basal inner, and an anterior elongate outer, streak at each side of the pro- 

 notum and also in some very irregular spots on the elytra, the whiter scales 

 of the under surface disposed somewhat as in the preceding, the abdominal 

 impression shallow and with sparser squamules; femora uniformly clothed 

 with yellowish scales; beak cylindric, nearly straight, arcuate distally, a 

 third longer than the head and prothorax, sculptured and clothed as in the 

 preceding; antenna? well beyond the middle, the third funicular joint but 

 little longer than wide and only half as long as the second; prothorax in 

 outline, carination and sculpture as in variegata; scutellum transverse, 

 acicularly cuspid at apex; elytra as in the preceding but more narrowly 

 ogival, rather obtuse at apex, the subapical umbo similarly feeble; striae 

 not so coarse, very deep, obscurely punctulate; intervals flat and densely 

 punctate. Length (cf ) 7.2 mm.; width 4.2 mm. Brazil (Chapada). One 

 example maculata n. sp. 



Body very much as in the preceding, the subdenuded oblique broad lateral 

 pronotal line almost entire, the inner area only evident at base; pronotal 

 punctures more distinct and much less dense, the scales slightly separated 

 and the surface lustre more shining; beak similarly long in both sexes, 

 thicker and more sculptured in the male, with the antennae more distinctly 

 beyond the middle, the third funicular joint a little more elongate, much less 

 than half as long as the second; pronotal carina moderate, polished and 

 smooth; basal lobe truncate, about a fifth the total width; scutellum similar 

 in form but more coarsely sulcate along the middle: elytra similar, except 

 that the punctulation and squamules are less dense, the latter also coarser 

 and longer; abdomen only just visibly impressed basally and similarly 

 squamulose in both sexes. Length (d 1 9) 7-0-7-5 mm.; width 4.0-4.4 mm. 

 Brazil (Santarem). Three specimens confusa n. sp. 



7 — Form rhomboid, rounded at apex, convex, feebly shining, black; narrow ful- 

 vous scales of the pronotum rather sparse, not concealing the sculpture,
