Brazilian Baring 25 



usual, the antennae submedial, the club triangular, acute, broadest basally; 

 prothorax conical, wider than long, strongly carinate and densely, rather 

 strongly punctate; scutellum aciculate at the middle behind; elytra ogival, 

 with rounded apex, scarcely a third wider than the prothorax; striae rather 

 coarse and deep, with distinct and well separated punctures along the bottom; 

 intervals flat, finely, densely punctate; abdomen with deep glabrous basal 

 impression, the white scales of the general surface becoming fulvous along its 

 margins. Length (c?) 7-2 mm.; width 4.2 mm. Brazil (Chapada — campo). 



September. One example • balteata n. sp. 



Strial intervals throughout on the flanks carinulate almost to the apex 10 



10 — Body nearly as in the preceding in outline but slightly stouter; integuments 

 black; dense uniform squamules of the pronotum pale yellowish in color, 

 also on the scutellum and humeri; anterior elytral fascia continuous from side 

 to side and feebly, irregularly arcuate, with interruptions as usual at the striae; 

 posterior angulate fascia rather broken, the sutural line uniting it with the 

 anterior fascia broader than in balteata and very uneven; divided apical spot 

 larger than in that species; scales beneath white; beak barely as long as 

 the head and prothorax, very feebly arcuate, notably thick, loosely squamu- 

 lose and carinate, becoming thinner distally, finely punctulate; antennae 

 slightly beyond the middle, nearly as in the preceding, the triangular club 

 with more arcuate sides; prothorax conical, wider than long, with the usual 

 lateral constriction at apex; punctures dense, the carina strong, but with 

 its summit fine and not exposed; scutellum as in balteata; striae moderate, 

 deep; intervals flat, finely, densely punctate; abdominal impression deep, 

 less glabrous than in the preceding, almost entirely covered with fulvous 

 scales, except at the middle of the first segment. Length (cf) 7-5 mm.; 

 width 4.35 mm. Brazil (Chapada). November. One example. 



luteicollis n. sp. 

 Body nearly as in the preceding but not quite so stout; color similar, the antennae 

 piceous; under surface rather sparsely squamulose and shining, densely 

 clothed in manner stated on the prothorax; scales of the pronotum small, 

 slender and close, fulvous, in color, fine, fulvous and sparse in the humeral 

 spot; surface of the elytra black as usual in this group and with widely 

 scattered small irregular spots of white squamules; only the posterior 

 chevron is distinct, with traces of the sutural line; beak evidently longer 

 than the head and prothorax, very feebly arcuate, rather shining, coarsely 

 punctured, finely distad, moderately thick, costulose and loosely squamulose 

 basally, somewhat reduced in thickness and smooth distally and finely 

 punctulate; antennae at four-sevenths (9), three-fifths (cf), the club with 

 deep sutures, subtriangular; prothorax rapidly conical, much wider than 

 long, the sides feebly arcuate; punctures strong, dense, longitudinally 

 coalescent, the carina distinct, with nude and shining summit; scutellum as 

 in the preceding; elytra also similar but only a fourth wider than the pro- 

 thorax; striae rather coarse and deep; intervals flat, densely punctulate; 

 abdomen broadly and shallowly concave and loosely, evenly squamulose 

 basally in both sexes. Length (cf 9) 6.9-7.7 mm.; width 4.0-4.2 mm. 

 Brazil (Chapada). October. Three specimens diffrangens n. sp. 



At least the humeral interval of the elytra is feebly carinulate in 

 all the species, but in some, such as parvula and centralis, there are 

 several others of the lateral intervals feebly carinulate, especially 

 behind. The genus is probably a large one in Brazil and occurs 

 also in the Central American region.
