REPORT ‘OF THE ENTOMOLOGIST. 71 
(not crescent-shaped like that of the common plum curculio,) 
wherein to deposit her eggs, five or six holes being found in 
one plum, from which the gum exudes copiously. The larva, 
instead of living permanently in the flesh of, the fruit, bores 
its way to the stone, and then feeds upon the kernel exclusively. 
The insect itself is said to feed upon the flesh of the plum, and 
takes wing readily. There is probably only one brood in the 
season. Destroying all fallen fruit, as in the case of the true 
plum eurculio, would probably lessen the number of these pests, should 
they increase so as to become troublesome. 
Horticulturists, growing evergreens for their beauty or effect in land- 
seape, are frequently annoyed by finding the leading shoots of pine, hem- 
lock, Norway spruce, &c., dying out, thus destroying the symmetry of 
the tree. The injury is frequently caused by the attacks of the yy, 16, 
white pine weevil, Pissodes strobi, (Pech.,) which deposits an egg — ~ 
in the terminal or leading shoot, and the larva, hatching, destroys 
the shoot by boring into it. The pupa is formed just under the 
bark, and the insect, which is of a grayish brown color, appears 
in April and May, after hybernating in the crevices of the bark. 
Some of these insects are said to come out in autumn, although they 
appear in much larger numbers early ir the season. All shoots thus 
infected should be cut out and burned, and in case the larva cannot be 
extracted without essentially injuring the branch, one of the leading 
side-shoots can be selected and bound in an upright position, so as to 
take the place of the terminal shoot which bas been cut off. 
Lixus concavus, (Say,) another curcalio of a lengthened — Fig. 17, 
form, dark-colored, and sometimes covered with a yellowish 
bloom, was found on the rhubarb, or pie-plant, in Washing- 
ton, in the act of boring into the stalk of the leaves and 
depositing its egg in the hole thus made. On examining 
the plant many of the leaves were found to be yellow and 
faded. These injured leaves mostly contained eggs, aud 
although no larve were found at the time, it is highly proba- 
ble that the larva of this insect causes considerable injary 
‘to the plants thus perforated, as an allied Huropean insect, 
Lixus paraplecticus, is stated to reside in the stems of Sium or water 
parsnip. 
The perfect insect of Epicerus vadosus, (Say,) or an allied pi, ig. 
species, was found in Maryland to be very destructive to cab- —° 
bages, clover, &c.. by eating holes in the leaves. Hpicwrus 
tmbricatus, (Say,) a very siniilar insect, was complaiued of as 
being injurious to the foliage of the apple and cherry trees. 
The larva of Caryborus arthriticus (Fab,) was found in palmetto 
seed brought by Mrs. Berrian, of Washington, from Pilatka, 
Florida. This larva lives in the seed, eating its interior in 
the same manner as the Bruchus pisi, or pea-weevil. The 
seed was entirely destroyed by this insect, one only of which 
Fig. 20. appeared to inhabit each seed or berry, The per- 
fect beetles came out in May or June. 
Horticulturists are well aware of the damage done by the 
© 61 common pea-weevil, Bruchus pisi, but it appears that a spe- 
\. cies hitherto unknown here has been lately introduced from 
Europe, which threatens, if not checked, to help its relative, 
., 6. pisi, in the work of destroying peas, &c.. iu this country. 
This insect, Bruchus granarius, is said to have been introduced 
into New York in some seed brought by a gentleman trom Switzerlaud
