20 INSECTS INJURIOUS TO FOREST AND SHADE TREES. 
their centers black. The under side of the body and the legs are brilliant coppery, 
the feet being deep shining green, their last joint and the hooks at its end black. 
Here also the surface is everywhere thickly punctured, the punctures on the venter or 
hind part of the body opening backwards. The last segment has an elevated line in 
the middle at its base, and its apex is cut off by a straight line, in the middle of which 
s commonly a small projecting tooth. The anterior thighs are remarkably large, 
from which circumstance this species has received its name, and they have an angular 
projection on their inner sides, beyond the middle. The tibiw, or shanks, of these 
legs are slightly curved. (Fitch.) 
Remedies.—We extract the following suggestions from Fitch: 
The remedies for destroying this borer must necessarily be much the same with 
those already stated for the common borer or striped Saperda. They consist essen- 
tially of three measures: First, coating or impregnating the bark with some substance 
repulsive to the insect; second, destroying the beetle by hand-picking; and third, 
destroying the larva by cutting into and extracting it from its burrow. ; 
As it is during the month of June and fore part of July that the beetle frequents 
the trees for the purpose of depositing its eggs in the bark, it is probable that white- 
wasbing the trunk and large limbs or rubbing them over with soft soap early in 
June will secure them from molestation from this enemy. And in districts where this 
borer is known to infest the apple trees the trees should be repeatedly inspected dur- 
ing this part of the year, and any of these beetles that are found upon them should 
be captured and destroyed. It is at midday of warm, sunshiny days that the search for 
them will be most successful, as they are then most active and show themselves abroad. 
The larye, when young, appear to have the same habit with most other borers, of 
keeping fee burrow clean by throwing their castings out of it through a small ori- 
fice in the bark. They can, therefore, be discovered probably by the new sawdust- 
like powder which will be found adhering to the outer surface of the bark. In Au- 
gust or September, whilst the worms are yet young, and before they have penetrated 
the heart-wood, the trees should be carefully examined for these worms. Wherever, 
from any particles of the sawdust-like powder appearing externally upon the bark, 
one of these worms is suspected, it will be easy, at least in young trees, where the 
bark is thin and smooth, to ascertain by puncturing it with a stiff pin whether there 
is any hollow cavity beneath, and if one is discovered, the bark should be cut away 
with a knife until the worm is found and destroyed. After it has penetrated the 
golid wood it ceases to eject its castings, and, consequently, we are then left without 
any clew by which to discover it. Hence the importance of searching for it seasonably. 
5. THE GREEN-HEADED BUPRESTIS. 
Buprestis chlorocephala. 
Order COLEOPTERA ; family BUPRESTID. 
Probably boring under the bark of the white oak, with habits similar to those of 
other flat-headed borers of the oak, a Buprestid beetle. 
(Observed by Mr. George Hunt laying its eggs on the bark of the white oak at 
Providence, in June). 
6, THE NORTHERN BRENTHIAN. 
Eupsalis minuta Drury. 
Order COLEOPTERA; family BRENTHID. 
Boring into the solid wood of the white oak, forming a cylindrical passage, a slender 
grub # inch long and not quite 0.05 inch thick, changing to a weevil with a large, 
very thick snout. 
The habits and transformations of this beetle were first described by 
Mr. Riley, the original account given by Dr. Harris proving erroneous,
