transversely strigose, whilst the interstices are broad, 
costate, and shining, and stndded 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 
Brachjjtemnus-ij'^e ; 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 tibiaB are armed 
at their inner angle with a robust spine ; and the hooks 
of all of them are powerflilly developed. Its feet are as 
slender as, and if anything even more elongated than, in 
Stenoscells ; 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 liimself near Rio Janeiro ; and it is at 
once conspicuous for the very unusual structure of. its 
greatly abbreviated antennae, — 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 antennse, 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
