THE LONGICORNIA. 
Tms section belongs to the large group of vegetable- 
feeders formerly known by the name of Tetramera, on 
account of their apparently possessing only four joints 
to the tarsi : this name has, however, been modified 
to that of “ Pseudo-tetramera,” or “ Sub -tetramera,” 
by Mr. Westwood, who pointed out that they have the 
normal five joints, although the fourth is so minute as 
usually to escape notice ; being, with the basal portion 
of the terminal joint, received between the lobes of the 
third joint, which is always more or less deeply 
notched at its extremity. The three basal joints are, 
also, always more or less strongly cushioned beneath. 
The other sections which have been classed together as 
possessing these characters are the Longioornia and 
the Rhynclurphora ; the latter, however, are now usually 
regarded as a group entirely apart from the rest. 
The Lonoicornia present a considerable family like- 
ness to each other, chiefly on account of their long 
antennal, which are never clubbed, but at most ser- 
rated, being generally filiform or setaceous, and having 
a long, thickened, basal joint. Their eyes are kidney- 
shaped, or strongly hollowed out in the middle of 
their front side, having the antennae frequently inserted
