Brazilian Baring 377 



the outer joints not compactly joined, gradually slightly more 

 transverse, the club oval, as long as the four preceding joints and 

 more obliquely pointed in the male. The prosternum is not modi- 

 fied and separates the coxae by one-half more than their width, 

 the apical constriction fine, deep and entire; the posterior lobe 

 extends to a line tangent to the middle coxae and is obtusely emar- 

 ginate. The legs are normal, the tarsi only moderately dilated and 

 the tarsal claws rather strong, arcuate and widely divergent; the 

 femora are completely unarmed. The prothorax is tubulate, the 

 basal lobe large, prominent and evenly rounded, the scutellum 

 transversely lunate, not exactly free, the elytra with extremely fine, 

 subobsolete, finely punctulate striae, becoming coarse and exarate 

 at apex and with large and very moderately prominent subapical 

 umbones and broadly tumid humeri. The pygidium is semicircular, 

 feebly oblique in both sexes, slightly larger in the male and always 

 feebly ridged along the middle.- In the male the beak has some 

 erect setae and often a subcrenulate edge beneath, somewhat as in 

 Pseudomadariis, but less developed. The three species at present 

 known to me are as follows: 



Sides of the prothorax strongly arcuate, except posteriorly, the third hind tarsal 

 joint well developed and dilated as usual 2 



Sides of the prothorax feebly arcuate, the third hind tarsal joint much smaller 

 and less dilated, though similarly bilobed; body smaller in size 3 



2— Body larger and more obese, deep black and polished, the large humeral red 

 area extending to the second stria; beak (c?) thick, shining, very moderately 

 and evenly punctured, as long as the head and prothorax — a little shorter 

 but otherwise similar ( 9 ) — and having an obtusely impressed channel at 

 each side, extending from base nearly to the antennae, the latter blackish; 

 prothorax large, a fifth wider than long, the sides feebly converging and 

 slightly arcuate, gradually rounding anteriorly, the tubulation much less 

 than half as wide as the base in both sexes, but especially in the male; punc- 

 tures sparse and very fine, somewhat more evident at the extreme sides; 

 elytra nearly one-half longer than wide, only very slightly wider than the 

 prothorax and four-fifths longer, the moderately oblique sides nearly straight, 

 the apex obtusely rounded, with reentrant sutural angle as usual in this 

 section; minutely punctured subobsolete strise deeper at the suture and on 

 the flanks; pygidium closely punctured and with slender yellowish squamules, 

 especially in the male, where there is a distinct medio-basal abdominal 

 impression. Length 9.3-9.8 mm.; width 4-1-44 mm - Brazil (Chapada). 

 October and November. Four specimens latus n. sp. 



Body not so large and distinctly narrower, similar in color, lustre and almost 

 similar in all structural characters, the beak a little shorter, not as long as 

 the head and prothorax (o 71 ), and still shorter and less thick ( 9 ) and more 

 finely punctate, the antennae nearly similar; prothorax relatively not so 

 large or broad, only very little wider than long, the sides nearly similar but 

 not quite so rapidly rounding anteriorly, the tubulation and sculpture 

 almost similar; elytra nearly similar throughout, but with somewhat less 

 oblique sides and still more obtuse apex; pygidium almost as in latus, but 

 exhibiting still greater sexual contrast, being relatively much smaller in the
