184 INSECTS: INJURIOUS TO FOREST AND SHADE TREES. 
Chrysalis,—Cylindrical, smooth, narrow, blackish-brown, about 16™™ in length. 
The head is pointed, there being a pronounced clypeal protuberance; the segments 
are unarmed; the anal plate is provided with a row of four spines, and two others, 
more slender, on either side of the mesial line, below the first. (Grote.) 
Moth.—The wings expand 30™™, Blackish-gray, shaded with reddish on the basal 
and terminal fields of the fore wings. There are patches or lines of raised scales on 
the basal field, and on the anterior and darker portion of the median space. The 
median lines are prominent, consisting of double black lines inelosing pale bands. The 
inner line at the basal third is perpendicular, (J-shaped or dentate. The outer line 
at the apical fourthis once more strongly indented below the costa. The black compo- 
nent lines do not seem to be more distinct on one side than on the other of the pale in- 
cluded bands or spaces. The median field is blackish, becoming pale towards the outer 
line; it shows a pale, sometimes whitish cellular spot, surmounted with raised scales. 
The terminal edge of the wing is again pale or ruddy before the terminal black line. 
Wings blackish. The hind wings are pale yellowish white, shaded with fuscous on 
the costal region and more or less terminally before the blackish terminal black line ; 
fringe dusky. Beneath, the fore wings are blackish, marked with pale on the costa; 
hind wings as on the upper surface. Body blackish-gray, with often a reddish cast 
on the thorax above and on the vertex. The eyes are naked, the labial palpi long, 
ascending, with a moderate terminal joint. Tongue rather long. The gray abdomen 
is ringed with dirty white; the legs are dotted with pale. The species differs from 
the European abietella by the raised scale tufts on the wings, and Zeller declares it to 
be distinct from any European species. (Grote.) 
54, THE PITCH-EATING WEEVIL. 
Pachylobius picivorus (Germar). 
A black weevil very similar to Hylobiuspales, but destitute of.any spots or dots, and 
having the same habits. This occurs in the southern part of our State, and becomes 
common farther south, but I have never met with it to the north of Albany. (Fitch.) 
Leconte separates as a distinct genus from Hylobius, H. picivorus, 
which differs greatly from the other allied species of Hylobius by the tibiae 
being much shorter and stouter, and expanding at the tip. It is abun- 
dant under pine bark, adds Leconte, in the Southern States, less fre- 
quent in the Middle States. 
55. THE WHITE-HORNED UROCERUS. 
Urocerus albicornis Fabricius. 
Order HYMENOPTERA ; family UROCERID&. 
A large black four-winged fly an inch long, having some resemblance to a wasp, 
but with a stout cylindrical body having the head and abdomen closely joined to the 
thorax, the base of the shanks and of the feet white, and also the antennwy except at 
their ends, and a spot behind each eye and another on each side of the abdomen, the 
wings smoky transparent. The abdomen ends in a point shaped like the head of a 
spear, below which is a straight awl-like ovipositor, about 0.40 long, with which it 
bores into the tree to deposit its eggs, the worm from which forms winding burrows in 
the wood, and is of a thick cylindrical form, divided into thirteen nearly equal seg- 
ments, including the head, which is small, polished and horny, the last segment being 
largest of all and ending in a conical horn-like point, and the under side with three 
pairs of very small legs anteriorly. 
These insects vary considerably in their colors and marks, and the two sexes are 
very dissimilar. The male, accoiding to Dr. Harris, is black, with a white spot be 
hind each eye, and a flattened rus.-colored abdomen. (Harris’s Treatise, p. 427.)
