peculiar mandibles, these being subvertical in plane and broadly, 

 deeply bifid at apex, or ( 9 ) shorter, a little more slender and 

 distally smoother, but otherwise nearly similar; antennae at three- 

 sevenths (cf) or barely behind the middle (9), slender, moderate 

 in length, the first funicular joint as long as the next two, the second 

 between two and three times as long as wide, the outer joints loose, 

 the seventh nearly as long as wide and densely pubescent, the club 

 small, narrowly oval, pointed and as long as the three preceding 

 joints. The prosternum is very large, even, with subobsolete 

 constriction, flat and horizontal behind, ascending beyond the inter- 

 coxal line, the suture wholly obsolete; posterior lobe not produced, 

 very broadly and shallowly' sinuate, the coxae separated by nearly 

 three times their width. The legs are rather long and simple, the 

 anterior longer, especially in the male, the anterior femora with a 

 small sharp inferior denticle, the others with the denticle very 

 minute or sobobsolete; the anterior tarsi are rather broad, the 

 claws moderate. Prothorax strongly and narrowly tubulate at apex 

 (o 71 ), or very briefly and more broadly (9), the basal lobe large, 

 prominent and angulate, the scutellum extremely short, transverse 

 and arcuate, the elytra coarsely, deeply and unevenly striate and 

 the pygidium subvertical in both sexes, small, feebly convex and 

 rounded. The type can be briefly described as follows: 



Paramadarus complexus n. sp. — Rather broadly, feebly cuneate-oval and 

 somewhat depressed above, deep black, the integuments shining, but clothed in 

 great part with a mixture of white and fulvous scales, dense in an oblique pronotal 

 line at lateral third and thence unevenly aggregated to the sides, on the elytra 

 unevenly aggregated and with a glabrous space about the scutellum, at the 

 middle of the suture and near the apex of each, also with dense whitish spots, 

 remotely arranged along parts of the intervals, close, fulvous and with uneven 

 condensations throughout the under surface, except broadly along the middle of 

 the abdomen, this being abruptly glabrous; beak three-fifths as long as the body 

 (o 71 ), about one-half (9), cylindric, closely and strongly punctate and with 

 fulvous squamules basally, smoother and glabrous ( 9 ) beyond the antennae, 

 which are nearly black; prothorax large, a little more convex anteriad, as viewed 

 in profile, a fifth ( d") or more than a fourth ( 9 ) wider than long, the sides parallel 

 and feebly arcuate in basal, oblique in apical, half; surface abruptly glabrous 

 and minutely, sparsely punctate in median third, thence to the sides coarsely, 

 unevenly and subrugosely punctate; elytra rapidly subparabolic, a fourth longer 

 than wide, equal in width to the prothorax and less than one-half longer; humeral 

 swelling subobsolete; surface somewhat uneven; alternate intervals feebly convex 

 and flat, with strong and more or less sparse, uneven punctures, the coarse striae 

 also punctate and squamose. Length 7.2-9.2 mm.; width 3.25-4.0 mm. Brazil 

 (Chapada). Nine specimens. 



In the male, the abdomen has a small feeble simple and nude 

 indentation at the middle of the apex of the first segment. The 

 first suture is fine but distinct.
