728 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
having quit*' similar larval habits. Daring the past summer I succeeded in getting 
the moth of one of them ; it is an /Egerian. as I think, undeecribed, bat I would not 
venture upon describing it had I only the imago ; bat as I am able to give mainly its 
history, and haying done so muoh tramping and olimbingfoi its sake, that I have 
conn- t<> feel a proprietary right, I nodertake to name and describe it as new. As its 
proposed Dame implies, the larva inhabits the pine, boriog under the bark and into 
the superficial layers of the wood. From the wounds thus made pitch exudes, which, 
through the action of the larva and the warmth of the sun, forms hemispherical 
! over its burrows ; in these masses the papa cells are finally prepared and the 
inactive stage passed. The larva occurs more frequently than elsewhere just below 
a branch; sometimes about the border of a wound made by the axe, or where a limb 
has been wrouched off by the wind ; rarely in the axil of the branch. It appears to 
attack larger trees than the Zimmerman's pine pest, and more frequently occurs at 
considerable altitude. I have taken them 30 to 40 feet from the ground. While 
they sometimes, perhaps as a rule, take advantage of the broken cortex, I have 
found them where it appeared that they had worked through the same into the soft 
layer. 
I have found the larva in the following localities : Hastings Center, N. Y. ; Portage, 
N. Y. ; Buffalo, N. Y. (?) ; Point Abino, Ontario. At the first-named place they were 
found in several instances numerous enough to seriously injure trees of moderate 
growth. I have taken the larva) in autumn from 0.25 to 0.75 of an inch in length; 
they finally attain a length of 1 to 1.1 inch ; diameter quite uniform, 0.18 of an inch. 
Color white ; headlight brown, flattened; first thoracic ring slightly clouded with 
brown, smooth ; no trace of an anal shield ; true legs scarcely colored, prolegs promi- 
nent, crowned with two rows of about eight hooks each. The brown hairs arise from 
papilhe, the base of each hair being surrounded by a brown annulation. The spira- 
cles are but slightly elliptical, last pair large, placed subdorsally. 
Before transforming they prepare a cell in the extruded pitcli mingled with their 
debris; this they line with silk, but spin no other cocoon. While in their burrows 
they move through the soft pitch with impunity, but if removed from the same they 
soon die from the incumbrance of the hardening pitch adhering to them. 
I have found the pupa the last of May ; the moth appears from the middle to the 
end of Juno. It may be that others come in July and August, for I have found larva 
apparently full grown in July. On the 15th of July I brought to my rooms, devoted 
to the rearing of insects, some blocks of wood containing such apparently mature 
larvae, expecting them to complete their transformations in a few weeks at most ; 
they are still in the pitch cells unchanged (November). Is it a case of retarded 
development, due to the drying of the bark and wood ? 
The pupa has a length of 0.73 of an inch. Color light brown with the extremities 
dark. Over the dorsal portion of the abdominal rings are the usual rows of teeth ; 
those on the anterior margius* scarcely extend below the spiracles. The clypeus is 
without a pointed process ; the medio-dorsal ridge of the thorax is unusually promi- 
nent. 
When about to transform it bores through the pitch wall and escapes, leaving the 
pnpa skin protruding. 
The moth (female) expands 1.2 inch. Forewings opaque ; hind wings transparent. 
Color blue-black, as follows: forewings, the clothed portions of hind wings, head. 
palpi, thorax, upper part of abdomen, antennas, and legs. The neck fringe and the 
sides of the collar are orange, also the ventral side of the abdomen and the tail 
fringes, as well as a band on the fourth abdominal ring. The antennae are long, 
slightly enlarged toward the end ; there is a decided orange line on the underside of 
the antennae for one-third their length; the tarsi are smoky. The male is smaller, 
but marked the same as in the female. (Canadian Entomologist, xiii, pp. 5-7, 157,
