Genera of the Cossonida. 593 



transversely strigose, whilst the interstices are broad, 

 costate, and shining, and studded with a single series of 

 large subasperated punctures), and their short, transverse, 

 abrupt, anteriorly-truncated, cup- (or somewhat calyx-) 

 shaped capitulum, are all of them characters which are 

 essentially their own. In its prothorax being comparatively 

 unconstricted in front Calyciforus is, likewise, on the 

 Brachytemnus-iy$Q ; nevertheless it is impressed ante- 

 riorly in the centre (which is not the case in that genus) ; 

 and both the prothorax and elytra are coarsely margined 

 at their respective bases. Its four anterior tibiae are armed 

 at their inner angle with a robust spine ; and the hooks 

 of all of them are powerfully developed. Its feet are as 

 slender as, and if anything even more elongated than, in 

 Stenoscelis ; but their third joint is still narrower and more 

 entire, being perfectly simple. 



121. EURYCORYNES (nov. gen.~). I am indebted to 

 Mr. Janson and Mr. Fry for the remarkable Cossonid 

 from which the details for the present genus have been 

 drawn-out ; and it has given me much pleasure in dedi- 

 cating the species to the former of these eminent Cole- 

 opterists. Like Calyciforus it is South- American, having 

 been received by Mr. Janson from the province of Minas 

 Geraes in Brazil ; while Mr. Fry's example appears to 

 have been taken by himself near Rio Janeiro ; and it is at 

 once conspicuous for the very unusual structure of its 

 greatly abbreviated antennas, the scape of which has the 

 joints gradually more and more transverse and lamelliform, 

 the last one of them being so thin as to be only just appre- 

 ciable against the enormously enlarged club. This latter 

 is most peculiar, being exceedingly wide, transverse, and 

 abrupt (more so indeed than in any member of the family 

 with which I am acquainted). In its thickened head, and 

 in the shortness of its triangular rostrum and antennas, as 

 well as in its sunken eyes and elongated slender feet, Eury- 

 corynes has much in common with Brachytemnus, Caly- 

 ciforus, and Stenoscelis ; but it agrees best with the last 

 of those three genera in the fact of its scutellum being 

 nearly obsolete, and in its elytra being asperated (though 

 less so, and in a different manner) both before and behind. 

 Nevertheless, in reality, it is perhaps nearer to Calyci- 

 forus, with which it agrees in its eyes being less widely 

 separated on the forehead, in its prothorax being less short- 

 ened, in its elytra being broadly sulcated (though not quite
