along the sides beneath; beak very short, evenly cylindric, slender, sparsely 

 punctate and not distinctly more than half as long as the prothorax, broadly 

 bent at the middle; antennae a little behind the middle, pale rufous, rather 

 slender, the first funicular joint as long as the next three, the club somewhat 

 shorter, with the basal segment glabrous and almost half the mass; prothorax 

 almost a third longer than wide, the sides parallel, feebly arcuate anteriorly, 

 straighter basally, gradually rounding to the briefly tubulate truncate apex, 

 which is three-fifths as wide as the base; surface transversely impressed 

 just before the basal margin, which is broadly and feebly arcuate; punctures 

 rather small and well separated, larger but shallow and rugulose laterally; 

 median line only partially smooth, feebly prominent only at the extreme 

 apex; scutellum nearly as in the preceding; elytra two and a third times as 

 long as wide, scarcely as wide as the anterior part of the prothorax, about 

 twice as long, parallel, the straight sides gradually arcuate and oblique in 

 nearly apical third to the narrowly individually rounded apices; striae fine, 

 their indistinct punctures bearing slender decumbent squamules; intervals 

 strongly, loosely rugose and rather shining; first ventral suture distinct, not 

 obsolete as in the preceding, the prosternum more convex medially behind 

 the coxae; legs nearly similar. Length 4.65 mm.; width 1.0 mm. Brazil 

 (Chapada). March. One specimen parvirostris n. sp. 



Sexual characters are not apparent in either of the above types, 

 which in reality form two different subgenera, because of the more 

 abrupt and differently divided antennal club, convex prosternum, 

 briefly tubulate thoracic apex and transverse subbasal impression, 

 different sculpture and altogether different vestiture of parvirostris. 

 The subgenus having parvirostris as the type may take the name 

 Camopisella (n. subgen.). 



Canopinus n. gen. 



In its shorter and broadly oblong bodily form, this genus bears 

 scarceh any resemblance to the otheis described above as Madop 

 terids, but there are certain structural features, such as the pos- 

 teriorly truncate prosternum, which seem to show that it forms a 

 part of this tribal group, and the beak, in general form and sexual 

 differences, is unlike anything else in the subfamily. The body is 

 glabrous above and strongly but sparsely sculptured, the punctures 

 beneath bearing small white squamules. sparse and uniform but 

 denser in a longitudinal line beyond each anterior coxa. Beak 

 straight, only feebly deflexed, slender and dorsally tricarinate in 

 basal half in the female, shorter, a little thicker and simply cylindric 

 in the male, separated from the head by a moderate impression. 

 Antennae just visibly behind ( 9 ) or beyond (cf 1 ) the middle, the 

 scape slender, not attaining the eye, the first two funicular joints 

 notably elongate, the second the shorter, the other joints more or 

 less evidently longer than wide and the club elongate-oval, pubescent 

 and scarcely longer than the three preceding joints, with its basal 

 segment nearly half the mass. Prosternum almost flat, with the
