90 INSECTA. 
BracuHyrpus. * 
In that of 
BaLaNINus, 
We find very singular Rhynchophora ; their proboscis is at least as 
long as the body, and sometimes much longer. The larva of oue 
species—Rhynchenus nucum, Fab.—feeds on the filbert f. That of 
RHYNCHENUS proper, 
Only differs from the preceding subgenera in negative characters, 
and from the following subgenus in the antenne, which consist of 
twelve joints {. In 
SyYBINEs 
We find but eleven, seven of which are anterior to the club §. 
Those are deprived of wings. Such is the subgenus 
Myoruinus, Schenh.—Apsis, Germ. 
To which we will unite the genera Tanyrhynchus, Solenorhinus, 
Styphlus Trachodes—Comasinus, Dej.—of Scheenherr. 
We now pass to those which have but nine or ten joints in the 
antenne, and possess the faculty of leaping. 
Cronus, Clairv. 
The Cioni do not leap, and they have nine or ten joints in their 
antenne. Their body is usually very short, and almost globular. 
Several of them, together with their larva, live on the Verbascum 
and Scrophularia ||. 
Next come those in which the posterior thighs are very stout, 
which enables them to leap. The antenne consist of eleven joints. 
The body is short and ovoido-conical. 
Those whose antennz are inserted into the proboscis, form the 
subgenus 
Orcuesres, Idlig.—Sauivs, Germ. 
Those in which they originate between the eyes, that of 
Ruampuus, Clairv. * * 
In the last Rhynchzeni of which we have to speak, the legs are 
remote at base, and the sternum frequently presents a cavity of more 
* The genera Brachypus, Brachonyx, Tanysphyrus, Anoplus, of Schcenherr. 
+ The genera Balaninus, Antliarhinus, Erodiscus, of the same. 
t The genera Heilipus, Orthorhinus, Paramecops, Pissodes, Penestes, Erirhinus, 
Anthonomus, Euderes, Derelomus, Coryssomerus, Accalopistus, Endaus, Tychius, Ster- 
nechus, and Tylomus, of the same. 
§ The genera Sybines, Microtogus—a subgenus of Tychius, the genus Ellescus, 
Dej.—Bradybatus (Rhinodes, De}.) 
|| The genera Cionus, Mecinus, Gymnetron, Schenh., in which the antenne con- 
sist of ten joints; the genus Nanedes of the same, and that of Prionopus, Dalman, 
where there are nine. See Oliv., Col., V, p. 106.
