gust and September and the winter succeeding, to give out the 
flies which appear in May. It is much more probable, however, 
that the flies all come out of their cocoons about the beginning 
of August, and like the species we have seen on the pines, pro¬ 
duce another brood of worms in autumn, which has escaped the 
notice of Dr. Harris; and it is these which lie in their cocoons 
through the winter and give out the flies which are met with 
in May. 
4. THE CEDAR AND JUNIPER .—Juniperus communis , etc. 
The wood of the red cedar (Juniperus communis ) is in high 
repute as being most repulsive to insects, especially to moths 
and other vermin which destroy clothing, furs, collections of 
insects, &c., hence it is prized before all other kinds of wood 
for the manufacture of drawers and boxes in which such articles 
are to be stored. And yet this wood has its particular enemies 
among this class of animals, which, so far from being poisoned 
are fed and nourished by it. In the Museum of the State Agri¬ 
cultural Society a specimen of this wood may be seen in which 
is a large hole bored by some insect, probably a species of wood¬ 
mining bee, in which to place the cells for nurturing its young. 
Another, and no doubt the most important enemy of the red 
cedar, is the first of the following species: 
284 . Cedar bark-beetle, Ilylurgus dentatus, Say. (Coleoptcra. Scolytidio.) 
Perforating small pin-holes through the bark, and between it 
and the wood excavating long slender burrows with numerous 
branches leading off therefrom at nearly right angles, similar to 
those of the Wood-engraver bark-beetle, No. 242; a very small 
cylindrical dark brown bark-beetle, scarcely the tenth of au 
inch long, its wing covers rough from little elevated grains 
which are more prominent towards the hind part, and arranged 
in rows with impressed lines forming little furrows between 
them. See Harris’s Treatise, page 77.
