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 

 prothoracic 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 antenna are blackish brown, the remainder paler. 

 A line of orange encircles each eye, and a stripe of the same colour runs from the 

 antennae 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 antennae, 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. The Lateral Elm Borer, Saperda lateralis, Fab, Order Coleoptera, Family 

 Cerambycidse. — 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 Dryobius, Dryohius sexfasciatus, Say, Order Coleoptera, 

 Family Cerambycidse. — 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 antennae are reddish 

 brown, the legs reddish, the thighs being dilated or swollen, the abdomen is banded 

 with yellow. I do 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 Dularius, Dularius hrevilineus. Say, Order Coleoptera, 

 Family Cerambycidae. — 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 antennae 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
