470 CLASSIFICATION OF THE RHYNCHOPHOROUS COLEOPTERA. 
the 1st and 2d very large connate, 3d and 4th very short, sut 
straight: lateral prolongation very narrow: groove on the i 
side of elytra narrow, gradually “ei "behind, fold exten 
nearly to the suture (somewhat as in Brenthide). 
This family is represented by Apion, a genus containing a l 
number of small species of pyriform body, and altogether | 
and of easily recognized appearance. So far as I have exa 
them they have well developed wings, though Lacordaire i 
that the body is apterous. This family is related to the Erirh 
tribe of true Curculionide. 7 
BELIDÆ. 
The Australian genus Belus, and the South American Hi 
ocerus, on examination present so many differences that I 
separated them to form a new family, which must be p: 
the present series. In fact, with a form of body greatly 
` bling Lixus of the true Curculionids, they have the dorsal 
inal segments of Apion; the ventral segments are, however, eqt 
or nearly so; the lateral prolongation is very narrow, and thou 
the edge is acute, the lateral fold on the inner face of the e 
extends only in the middle third, and is nearly confluent with 
margin at its front end. The antennæ are slender, 11 
straight, and the scape is moderately long. The tibiæ are 
truncate at tip, and the hind pair have two small but 
spurs as in normal Coleoptera. ; 
In the ¢ of Belus the apex of the elytra is prolonged 
many species of Lixus; and this family seems related és 
onine tribe of Curculionids as Apion is to the Eri 
slight trace of epipleura may be observed at the front part 
elytral side margin, thus showing also a relationship | 
Rhynchitide of the first series, in which, as I have al 
tioned there is a feeble fold on the inner face of the ely? 
the middle, but quite distant from the margin.— Cone
