THE LONGICORNIA.

the intermediate tibiae obliquely truncated, and with a 
setose tubercle on the outer side behind the middle, 
the thorax is armed with a lateral spine, and the 
mandibles are short. 
In this sub-family some of our largest and most 
curious Longicornia are found ; Lamia textor and Asti- 
nornus xdilis being especially remarkable. The 
former of these is a large, clumsy, convex, dull black 
insect, found near Bristol, and at Raunoch in 
Perthshire, on willow-trees and in osier beds, the 
top shoots of which it is reported to weave together 
as a nidus. 
The other, A. xdilis (Plate XIII., Fig. 4), is con- 
spicuous for the enormous length of its antennae, 
especially in the male. This, also, occurs at Raunoch, 
where it may be not uncommonly seen flying across 
the glades of the Black Forest with its long appen- 
dages streaming behind. It loves to settle on felled 
pine logs, with its antennae spread out like compasses ; 
from which habit it is termed by the Highlandei’s 
“ Timberman ; ” a name, curiously enough, also ap- 
plied to it in Lapland and Sweden, where it is com- 
mon. If two males come within range they inevitably 
fight; for which reason, and also on account of their 
delicate structure, it is difficult to obtain quite perfect 
specimens. 
The larva makes wide galleries aud perforations in 
pine stumps, forming a nidus with coarse gnawed 
fragments near the surface, in which it changes to 
pupa. In this state the antenna) are turned down- 
wards aud recurved towards the middle of the head. 
The larva appears to be full fed at the beginning of 
the summer, and, after remaining two or three weeks
