EUPAGODERES.—AMPHIDEES. 97 
and slender, with series of rather large deep punctures. Posterior tibiee thick at the 
extremity and with unusually large apical truncature. The whole insect is covered 
with somewhat shining scales, and the maculation is due to some of these being dark 
in colour. Three examples. 
The apparent absence of fimbrize from the ocular lobes suggests that this species may 
belong to the genus Sapotes, Casey, but I do not think it necessary that it should be 
separated from Hupagoderes at present. 
AMPHIDEES. 
Amphidees, Schéuherr, Gen. Cure. vi. 2, p. 252 (1842) ; Lacordaire, Gen. Col. vi. p. 242. 
This genus was established by Schonherr for a single Mexican species, and I now 
add several others. ‘These differ among themselves by small structural distinctions in 
the ventral segments and apices of the hind tibie, as well as in the thickness of the 
rostrum ; but I am quite unable to look on these minute structural characters as of 
more than specific importance. A. pilosus differs rather more strongly, but I do not 
think it necessary to separate even it at present. 
Viewed in this way, I define Amphidees as embracing such ‘ Otiorhynchine aptere’ 
as have ocular lobes, and in which the rostral scrobes are broad and indefinite behind ; 
this latter character being the essential point of distinction from Hupagoderes. In our 
region, therefore, the genus is the equivalent of Horn’s group Strangaliodes. The 
posterior corbels are more or less imperfectly cavernous, except in A. pilosus, where I 
think they may be described as open.

This greatly resembles an elongate Hupagoderes of the E. cinereus group of species, 
and is covered with scales ina similar manner; the rostrum, too, is only a little more 
slender, but its scrobes are excessively broad and vague posteriorly, so that a glance is 
sufficient to enable one to appreciate the distinction between the two genera. The 
forehead has a convexity slightly separate from the plane of the rostrum; the latter 
has a vague elevation of its middle near the base, and in a line with this there is a 
small longitudinal fovea on the forehead; the antenne are elongate and slender, the 
first and second joints of the funiculus equal in length, the club elongate, slender, and 
acuminate, the sutures distinct, the eighth joint very abruptly separated from the club. 
Thorax strongly transverse, evenly rounded at the sides. Elytra considerably broader 
than the thorax, with a raised margin behind the scutellum, which is unusually distinct ;
