251 . Pitch-eating weevil, Hylobius picivorus, Schonherr. 
A black weevil very similar to the preceding 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. 
See Harris’s Treatise, p. 62. 
252 . White-horned Urocerus, Urocerus albicornis, Fabricius. (Ilymen- 
optera. Uroceridse.) 
[Plate iii, fig. 2.] 
A large black four-winged fly an inch long, having some 
resemblance to a wasp, but with a stout cylindrical body hav¬ 
ing the head and abdomen closely joined to the thorax, the 
base of the shanks and of the feet white, and also the antenna) 
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 segments, 
including the head, which is small, polished and horny, the last seg¬ 
ment beinglargest 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, according to 
Dr. Harris, is black, with a white spot behind each eye, and a 
flattened rust colored abdomen. See Harris’s Treatise, p. 427. 
253. Yellow-banded Urocerus, Urocerus abdominalis, Harris. 
A four-winged fly similar to the foregoing, about 0.80 long, 
of a blue-black color, with from two to four of the middle seg¬ 
ments of its abdomen bright orange yellow, and also a broad 
band on the antenme and the four forward legs except at their 
bases, its wings hyaline, tinged at the tips with smoky. There 
is sometimes a yellow spot behind each eye, and the hind knees 
and some or all of the joints of the hind feet are usually yellow. 
My specimens are males, nor has any female answering to this 
been found, and I am forced to entertain suspicions it is the
