Brazilian Barin^e 267 



parallel toward base; elytra nearly similar but with more elevated humeri, 

 and with the strise still less obsolete, being in fact distinct though fine, the 

 punctures subsimilar; male abdomen nearly similar, the prosternal spines 

 half as long as prothorax, their posterior basal rounded angle more obtuse, 

 the canal narrower anteriorly, more rapidly dilated behind and with less 

 abruptly defined margins. Length 5.5 mm.; width 2.4 mm. Brazil 

 (Santarem). One specimen tubifera n. subsp. 



I have not seen the type of this genus — Cylindrocerus flabellitarsis 

 Boh., from Cayenne — but it is in all probability different from any 

 of the above. The female seems to be rare. 



This genus has given rise to some misunderstanding. According 

 to Lacordaire it is a Madarid, with widely separated anterior coxae 

 and a prosternum armed with two short subapical spines in the 

 male. The very peculiar anterior male tarsi described by that 

 author, coincide closely with those of the present interpretation of 

 the genus, which is unmistakably a Centrinid near Cylindrocerus. . 

 The fact that the type species was described as a Cylindrocerus in 

 the work of Schonherr, would seem to show that the present iden- 

 tification is correct, but what the Dactylocrepis of Lacordaire can 

 be, I have no means of knowing at present. It is stated by Schon- 

 herr that the pygidium is concealed in Dactylocrepis, while in that 

 genus as interpreted by Lacordaire, the pygidium is uncovered. 



Nedestes n. gen. 



The body in this genus is broadly rhomboidal, polished and 

 glabrous, the beak very long, cylindric, strongly and evenly arcuate, 

 the long slender antennas at basal fourth, the scape almost attaining 

 the eye, the funicular joints all elongate, the first three notably so 

 and diminishing more or less regularly in length, the club long, 

 slender, subcylindric, gradually finely pointed at apex, with its 

 basal segment half the mass, the sutures fine. The mandibles are ex- 

 traordinary — rather long, straight, apparently not contiguous when 

 closed and very difficult to describe adequately in language; viewed 

 dorsally there are two segments, the basal the shorter, hollowed 

 dorsally, with the sides of the hollow elevated, the apical segment, 

 oval, rounded externally at base, obliquely excavated longitudinally 

 throughout the length of its upper surface, with the apex rounded; 

 the basal segment is deeply constricted internally near the base; 

 the tip of the beak above the mandibles is broadly sinuate. The 

 beak is separated from the head by the feeblest possible incurvature 

 when viewed in profile. The anterior coxae are rather widely 

 separated, the prosternum in the male with two long, porrect and 

 outwardly curvate processes, separated at base by a very deep 

 circular excavation. The legs are rather long, the tibiae straight, 

 the anterior not fimbriate in the male, except briefly so at apex,
