THE BANDED STENOCORUS.

slender and tapering, sometimes of moderate length, some- 
times excessively long, especially in the males ; the thorax 
is longer and more convex than in the preceding family, not 
thin-edged, but often rounded at the sides. 
Some of these beetles, distinguished by their narrow wing- 
covers, which are notched or armed with two little thorns at 
the tip, and by the great length of their antennae, belong to 
the genus Stenocorus, a name signifying narrow or straitened. 
One of them, which is 
rare here, inhabits the 
hickory, in its larva state 
forming long galleries in 
the trunk of this tree in 
the direction of the fibres 
of the wood; This beetle 
is the Stenocorus ( Ceras- 
phorus) ductus ,* or band- 
ed Stenocorus (Fig 4(5). 
It is of a hazel color, with 
a tint of gray, arising from 
the short hairs with which 
it is covered ; there is an 
oblique ochre-yellow band 
across each wing-cover ; and a short spine or thorn on the 
middle of each side of the thorax. The antennas of the 
males are more than twice the length of the body, which 
measures from three quarters of an inch to one inch and one 
quarter in length. 
The ground beneath black and white oaks is often ob- 
served to be strewn with small branches, neatly severed from 
these trees as if cut oft with a saw. Upon splitting open the 
cut end of a branch, in the autumn or winter after it has 
fallen, it will be found to be perforated to the extent of six 
or eight inches in the course of the pith, and a slender grub, 
the author of the mischief, will be discovered therein. In
