188 INSECTS INJURIOUS TO FOREST AND SHADE TREES. 
the work of small birds, which are very efficient and serviceable in fer- 
reting out and devouring the larve and pup of this weevil. And, in 
addition to these, it has several insect enemies which aid in restraining 
it from becoming excessively numerous. But notwithstanding the great 
inroads which are hereby made upon its ranks, this is quite a common 
insect in every part of our State and country where the pine abounds, 
deforming these valuable trees and retarding their growth. The pro- 
prietor of every grove of young pines should therefore make it a rule to 
examine them every year, in August or September, and cut or break 
oit the top of every tree that is blighted by these weevils and commit 
it to the flames. 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 fora 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, and labor that will be amply rewarded. 
To the foregoing account, copied from Fitch’s Fourth Report, we will 
only add that we have observed the weevil in all its stages of growth at 
Brunswick, Maine, under the bark of white pine shrubs, the last of 
April, the larvee at this date being more numerous than the pup or 
beetles. Our larvee were .32 inch long. The pupa is white, the tip of 
the abdomen 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 two to four feet in diaineter, variously distorted by the attacks in 
early life of this weevil; one in particular, at Brunswick, we are famil- 
jar with, nearly four feet thick at the base, and which subdivides into 
eight shafts, the central one wanting. 
We have also found the insect in abundance in September, on the 
ornamental pine bushes on the grounds of the Massachusetts Agricul- 
tural College, at Amherst, Mass. 
59. THE WHITE-PINE APHIS. 
Lachnus strobi Fitch. 
Order Homoptera; family APHIDE. 
Colonies of plant-lice on the ends of the branches, puncturing them 
and extracting their juices, the bark of the infested trees having a pecu- 
liar black appearance; numbers 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 powder, with a 
row of white spots along 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
