Brazilian Baring 379 



with extremely fine and scarcely traceable striation on the disk. 

 The pygidium is evenly convex, subvertical and more or less semi- 

 circular, narrower in vernicatus. The two known species are as 

 follows : 



Form rather broadly rhombic-oval, convex, very smooth, polished, black and 

 devoid of sculpture, wholly glabrous above and beneath; beak (9) thick, 

 evenly cylindric, straight, arcuate and just visibly tapering distally, as 

 long as the head and prothorax, minutely and remotely punctulate, the 

 upper surface with a deeply impressed broad channel from basal to apical 

 fifth; antenna at four-sevenths, blackish, the scape gradually rufous basally; 

 prothorax a fifth or sixth wider than long, the sides evenly and moderately 

 arcuate, becoming subparallel at base and very feebly sinuate at apex, the 

 latter truncate and much less than half as wide as the base, the basal lobe 

 prominent, bluntly angulate at tip and with a feeble basal impression at 

 each side; punctures minute, remote and very feeble; elytra oval, with 

 rather prominent humeri but no subapical umbones, a fourth longer than 

 wide, distinctly wider than the prothorax and three-fifths longer; striae 

 excessively fine, subobsolete except at the suture and on the flanks, not 

 stronger at apex, minutely punctulate, the general surface minutely, remotely 

 and evenly punctulate; pygidium distinctly but sparsely punctate, even and 

 semicircular; prosternum in the type not transversely constricted at apex, 

 but with a large and rounded, very deeply impressed apical pit, the basal 

 emarginate lobe briefly and sparsely setulose. Length 7.5 mm.; width 3.7 

 mm. Brazil (Para). June. One specimen. [Eudamarus in sp.]. 



impressirostris n. sp. 

 Form narrower, much more evenly oval, smooth, deep black, polished and gla- 

 brous, except that the entire met-episterna and the sides of the abdomen 

 behind the second suture are densely clothed with orange scales; beak ( 9 ) 

 not quite so stout, evenly and moderately arcuate, cylindric though feebly 

 compressed at the sides basally, separated from the head by a much deeper 

 impression and with the punctures much larger, deep and denser, somewhat 

 longer than the head and prothorax and not at all impressed dorsally ; an- 

 tennae rather beyond four-sevenths, rufous, fuscous distally, almost similar 

 but with the club longer than the preceding six joints; prothorax a sixth 

 wider than long, the sides converging and straight to apical third, there 

 rounding and thence oblique to the apex; basal lobe large, broadly rounded; 

 punctures fine and sparse but very evident; scutellum broadly ogival, less 

 sinuate at base than in the preceding; elytra very evenly oval, nearly a 

 third longer than wide, with almost obsolete humeral swelling, slightly wider 

 than the prothorax and nearly three-fourths longer; sculpture almost as in 

 the preceding, the minute strnal punctures more distinct; pygidium smaller, 

 narrower, scarcely wider than long and with coarser and much closer, very 

 deep punctures; prosternum not modified at apex, excepting a small sinuation 

 of the edge; it and the entire under surface much more strongly and closely 

 punctured than in the preceding. Length 5.7 mm.; width 2.7 mm. Brazil 

 (Santarem). One specimen. [Damarites n. subgen.] vernicatus n. sp. 



As may be perceived very readily, there are two distinct subgenera 

 represented by the above two species. The Calandra corvina of 

 Fabricius, placed in Madarus by Boheman, belongs to the present 

 genus, but there are several characters mentioned by the latter 

 author that do not harmonize very well with impressirostris, and
