straight, tapering rapidly from base to the middle and thence very 

 smooth, slender and dorsally flattened to the apex; it is not separated 

 from the head by any kind of an impression and the mandibles are 

 long, with their inner margins straight. The antennae are medial 

 (d 1 ) or slightly behind the middle (9) and are moderately long, 

 the first two funicular joints notably elongate, the second slightly 

 the shorter and the remainder all short, the seventh much larger 

 and more pubescent in the male, the club small, very short and 

 virtually globular and only about as long as the two preceding. 

 The prosternum is very flat and even throughout in both sexes, 

 the coxae remote, separated by almost twice their width. The 

 scutellum is subtransverse, nearly quadrate, rather convex and 

 glabrous, the elytra with punctured grooves. The tarsal claws are 

 widely divergent, arcuate and free. The type is as follows: 



Remertus marginatus n. sp. — Elongate-oval, with slightly prominent humeri, 

 black, convex, the beak densely sculptured and squamulose basally, the pronotum 

 glabrous and shining, with an abrupt dense entire marginal vitta of ochreous 

 scales; elytra glabrous, but with the bases of all the intervals clothed with dense 

 ochreous scales, these covering apical half of the second, the median part of the 

 third, extending throughout the fourth to apical fifth and, on the eighth, from 

 the humeri to the sutural angle; strong punctures of the under surface each with 

 a small whitish squamule, these longer and dense on the outer part of the meso- 

 sternum and outer part of the met-episterna; on the inferior thoracic flanks the 

 ochreous scales descend at apex nearly to the middle, and there is a vitta of 

 whiter scales just outside of the coxae; beak (cf ) as long as the head and pro- 

 thorax, relatively slightly longer (9), the antennae piceous; prothorax (o 71 ) 

 feebly Convex in profile, virtually as long as wide, with arcuate sides, gradually 

 less so and subparallel behind the middle, the apex a little more than a third as 

 wide as the base, the surface finely, sparsely punctate, the basal lobe rather 

 broadly but prominently rounded, more strongly, densely punctate and with 

 convex peripheral surface, or ( 9 ) strongly convex in profile and a fifth or sixth 

 wider than long, otherwise nearly as in the male; elytra parabolic but strongly 

 rounded at tip, a third longer than wide, distinctly wider than the prothorax and 

 three-fifths longer (o 71 ), or two-thirds (9); grooves rather coarse, the wide fiat 

 intervals strongly, densely, confusedly and subrugosely punctate; abdomen (o 71 ) 

 finely, somewhat closely punctulate, with a very deep concavity along the middle 

 in basal half, or ( 9 ) not impressed and more strongly, much more sparsely 

 punctate. Length 5.8-6.8 mm.; width 3.0-3.7 mm. Brazil (Chapada — campo). 

 October. Three specimens. 



The remarkable characters of this species and the notable and 

 diversified sexual differences necessitate the rather long description 

 given above. 



Forandia n. gen. 



In its somewhat dense and uniform fulvous vestiture this genus 

 departs strongly in habitus from any of the preceding, and this 

 habital difference is supplemented by numerous structural peculi- 

 arities. The beak is rather short, smooth, cylindric and nearly
