opterous insects, characterized 
by the (usual) prolongation of 
the head into a snout or pro- 
boscis (whence the name); the 
weevils, curculios, or snout 1 
beetles. In Latreille's classifica- 
tion (1807), the Rhynchophora were the 
first family of the Coleopttra tetrame- 
ra. They have the palpi typically 
rigid, without distinct palparitc, the 
maxillary four-jointed and the labial 
three-jointed ; labrum typically ab- 
sent : gular sutures confluent on the 
median line; prosternum cut off behind by the epimera, 
and prosternal sutures wanting ; and the epipleune of the 
elytra generally wanting. The characteristic beak or ros- 
trum varies from a mere vestige in some of these insects 
to three times the length of the body. The antenna; are 
generally elbowed or geniculate, with the basal joint or 
scape received into a groove or scrobe. The larvae are leg- 
less grubs ; some spin a cocoon In which to pupate. This 
suborder is divided into 3 series, and contains 13 families. 
The species are all vegetable-feeders except Brachytargus, 
which is said to feed on bark-lice. They are very numer- 
ous, being estimated at 30,000, and many are among the 
most injurious insects to farm, garden, and orchard. See
