It differs from the larva of Saperda vestita, Say, in the shorter body, which 
is broader, more hairy, with the tip of the abdomen flatter and more hairy. The 
prothoracie segment is broader and flatter, and the rough portion of the dorsal 
plates is larger and less transversely ovate.” 
These destructive grubs by tunnelling and undermining, loosen large portions 
of the bark, stopping the flow of sap, weakening and finally killing the tree. 
The perfect insect is a flat-bodied beetle, measuring from four to six-tenths 
of an inch in length. It is of a rather dark brown colour above, with a grayish 
tinge caused by a coat of very short downy hairs. The under surface blueish 
gray. The basal joints of the antennez are blackish brown, the remainder paler. 
A line of orange encircles each eye, and a stripe of the same colour runs from the 
antennz to the hind margin of the thorax, and is continued along the edge of the 
wing-covers where they are bent down over the sides of the body, getting 
narrower gradually until it reaches the tip. From this border, three branches or 
teeth run obliquely towards the inner edge of the wing-covers, the middle one 
being the longest. There are six small black spots on the thorax, two on top just 
behind the antenna, and two on each side below the orange stripe, and at each 
angle of the stripes on the wing-covers, there is a small dark patch or spot. 
Any trees known to be attacked by borers should be cut down in the fall or 
during the winter, and used for firewood, care being taken not to leave any ex- 
posed during the summer; particularly in June and July, as at this time most of 
our borers deposit their eggs. It follows, therefore, that no freshly cut, or fallen 
trees, or branches should be left lying about, and if cordwood is piled, it should 
be covered, as the borers will surely find all newly felled wood if left exposed, 
and where such carelessness is permitted, will congregate and multiply year after 
year. ; 
2. Tae LaTeRAL Em Borer, Saperda lateralis, Fab, Order Coleoptera, Family 
Cerambycide.—This beetle very closely resembles the preceding species, and its 
habits appear to be the same; it differs somewhat in markings, as the orange 
border on the wing-covers wants the three teeth running towards the inner mar- 
gin. It bores in the inner bark of the elm, appearing in June, but seems to be 
less common than Saperda tridentata. 
3. THE SIX-BANDED Dryostus, Dryobius sexfasciatus, Say, Order Coleoptera, 
Family Cerambycidee.—According to Dr. Fitch, the larva of this species is similar 
to that of Saperda tridentata, and is found along with it; it is, however, larger 
than that species. 
The perfect insect is a black beetle measuring from three-fourths to seven- 
eighths of an inch in length. The general colour is black, the thorax deeply 
margined with yellow, and each wing-cover is ornamented with four oblique’ 
bands of the same colour; the scutel, as entomologists name the little triangular 
piece at the base of the wing-covers, is also yellow. The antenne are reddish 
brown, the legs reddish, the thighs being dilated or swollen, the abdomen is banded 
with yellow. Ido not find this species on the Society’s list of Canadian beetles, 
but think I have seen it recorded by a Canadian entomologist. 
4. THE SHORT-LINED Dutartius, Dularius brevilineus, Say, Order Coleoptera, 
Family Cerambycidze.—This is a large black longicorn beetle, with dark blue wing- 
covers, not covering the whole of the abdomen ; a rounded thorax, flattened above 
and the thighs very much swollen. “The antenne are about two-thirds the 
length of the body, flattened towards the end, and somewhat serrate. The body 
above is velvety black, and brown black beneath. The head is black and coarsely 
punctured, and the prothorax is covered with short, dense, black hairs, like velvet. 
The wing-covers are Prussian blue in colour, bent, corrugated, with an interrupted 
ridge just outside the middle of each cover. They are covered with fine black
