ANNUAL REPORT OF NEW YORK 
POPLAR. TRUNK. 
minute oval yellowish white lice 0.02 long, with blackish legs, the femalo 
more or less coated with white meal on her back, 0.07 long, oval and pale 
yellow with blackish legs and antennas. Though I have not yet met with 
winged individuals, they in all probability pertain to the genus to which I 
have referred this species above. The galls may frequently be noticed on 
elm leaves. By the middle of summer they become tenantless, dry and 
bard and of a blackish brown color. 
4. THE POPLAR— Populus grandidentata, etc. 
AFFECTING THE TRUNK. 
348. Broad-necked Prionus, Prionus laticollis, Drury. (Colcoptcra. Cerambycidm.) 
In the wood of the trunk and roots of different poplars, a white soft grub 
as thick as one’s thumb and otherwise similar to that of the Chestnut-brown 
or Pennsylvania Prionus, § 234*; producing an oval moderately convex 
black long-horned beetle 0.90 to 1.50 long and less than half as broad, its 
wing-covers rough from confluent irregular punctures and with two or three 
raised lines, its thorax with three irregular teeth along each side, and its 
antennee of twelve joints resembling little conical cups placed one within 
the other and projecting upon their lower side like the teeth of a saw; ap¬ 
pearing abroad in July. 
349. Pgplar-uorkr, Sapctda calcar at a , Say. (Colcoptera. Cerambycideo.) 
Beneath the bark and in the interior of the wood boring a hole 0.45 wide 
and less than half as high, a yellowish white footless grub 1.75 long, slightly 
tapering and divided by strong constrictions into twelve rings, the first one 
largest and with its upper side flattened, tawny and slopeing forwards, and 
in all other respects resembling the Apple-tree borer, § 2 ; passing its pupa 
state in the tree and coming out in August and September, a pale bluish 
gray long-horned beetle, about an inch long and a fourth as broad, finely 
dotted with black, its scutel ochre yellow and also three stripes on its tho¬ 
rax and several spots on its wing-covers. See Harris’ Treatise, p. 93. 
AFFECTING THE LEAVES. 
350. Wuite-S Ci.ostera, Clostera albosigma, Fitoh. (Lcpidoptcra. Notodontidoo.) 
Early in July, eating the leaves and reposing in a cavity formed of 
leaves drawn together like a ball, a large black caterpillar with white and 
yellow dots and stripes and a hump on the back of its fourth and eleventh 
rings; its pupa lying in a cocoon attached among the leaves, and in ten 
days giving out the moth the latter part of July ; the moth grayish-brown, 
its fore wings crossed by three faint paler streaks, the two first parallel, 
the hind one with its outer half silvery white and strongly waved in the 
shape of the letter S ; width 1.50. See Transactions, 1855, p. 506. 
• Since my lost report was in print I have ascertained that the fifth volume of Dcgecr’s 
work was not published till 1775. Forster's name of this insect consequently 1ms the priority, 
and Chestnut-brown Prionus, Orthosoma brunnea, Forster, should be substituted for tho 
name I have in that place givou.
