blighted by these -weevils and commit it to the iiames. With every shoot that is 
thus treated, from ten to fifty or more of these weevils will be destroyed, which 
otherwise will come abroad the following year to dwarf and deform a number of the 
other trees in the same manner. No one, on casting this subject over in his mind for 
a moment or two, will doubt but that a few hours devoted to such work, or a whole 
day, should it be required, will be time -well spent, aud labor that will be amply 
rewarded." 
To the foregoing account, copied from Fitch's Fourth Keport, we will 
add that we have observed the weevil in all its stages of growth at 
Brunswick, Me., under the bark of white pine shrubs, the last of April, 
the larvae at this date being more numerous than the pupae or beetles. 
Our larvae were .32 inch long. The pupa is white, the tip of the abdo- 
men being square, with a sharp spine on each side. It is .30 inch in 
length. There are often to be seen in the forests of Maine trees, from 
2 to 4 feet in diameter, variously distorted by the attacks in early life 
of this weevil. 
TO. The white pine aphis. 
Lachnus strobi Fitch. 
Order Homoptera ; family Aphid^:. 
Colonies of plant-lice on the ends of the branches, puncturing them and extracting 
their juices, the bark of the infested trees having a peculiar black appearance ; num- 
bers of ants in company with them, and traveling up and down the trunks of the 
trees which they inhabit. The winged individuals 0.20 long to the tips of their 
wings, black, hairy, and sometimes slightly dusted over with a white meal-like pow- 
der, with a row of white spots aloug the middle of the abdomen, the thighs dull 
pale-yellow at their bases, and the fore wings hyaline, with black veins, of which 
the forked one is exceedingly fine and slender. The wingless individuals far more 
numerous, 0.12 long, brownish black with a white line along the middle of the thorax 
aud white spots along each side of the abdomen, which are sometimes faint or want- 
ing, the antennae pale, with their tips black. 
71. The parallel spittle-insect. 
Jphrophora jxtralleUa Say. 
Order Hemiptera (Homoptera); family Cercopid^e. 
In June, a spot of white froth, resembling spittle, appearing upon the bark near 
the ends of the branches, hiding within it a small white wingless insect having six 
legs, which punctures and sucks the fluids of the bark, and grows to about a quarter 
of an inch in length by the last of that month, and then becomes a pupa of a similar 
appearance, but varied more or less with dusky or black, and with rudimentary 
wings resembling a vest drawn closely around the middle of its body ; the latter part 
of July changing to its perfect form, with wings fully grown, and then uo longer 
covering itself with foam, but continuing to the eud of the season, puncturing and 
drawing its nourishment from the bark as before. The perfect insect a flattened 
oval tree-hopper, 0.40 long, with its wing-covers held in form of a roof, its' color 
brown from numberless blackish punctures upon a pale ground, a smooth whitish 
line along the middle of its back, and a small smooth whitish spot in the center of 
each wing-cover, its abdomen beneath rusty brown. (Fitch.)
