the boles made by this borer as probably those of Ghalcopkora vir- 
ginien.sis, but they are regularly oval cylindrical, less flattened oval 
than those made by a Buprestid, and exactly like those of other flat- 
bodied longicorns. The openings, usually most abundant on the south r 
side of the tree or stump, in the base of the trunk of the white pine, 
are at times very numerous, as many as ten in a space of 5 square 
inches. They are, on the average, G""" wide by 3"" 11 deep, or half aa 
deep as wide. The sides are smooth, but the orifice is often partially 
concealed by projecting portions of the bark. The holes are deep, ex- 
tending 6 or 8 inches towards the heart of the tree. Seen longitudi- 
nally the "mine" or tunnel is about a quarter of an inch (6 min ) wide, 
sometimes wider, and ends in an elongate oval cell, wherein the pupa 
rests. Some extend up and down under the bark, while most of them 
plunge deep into the wood. 
Larva. — Prothorax inclined downwards 
towards the head ; quite long and not very 
wide, being no wider than the mesotho- 
racic and metathoracic segments, the 
squarish area being very long, naked on 
the basal third, the front margin pale 
brown, chitinous. Mesothoracic and met- 
athoracic segments as wide as the protho- 
racic ; the metathoracic slightly longer 
and fully as broad as the mesothoracic seg-

the second the shortest and the seventh 
the lougest ; the eighth two-thirds as long 
as the seventh and considerably narrower : the ninth one-quarter as loug as the eighth 
and three-fourths as wide; the tenth only seen from beneath, and about two-thirds 
as wide as the ninth, and bilobed at the end. On the two hinder thoracic and the 
first abdominal segment are transverse regular oblong areas bounded by impressed 
lines; on segments 2 to 4 the callosities are narrower, and the anterior side is pointed ; 
on the sixth and seventh they are a little longer than broad and contracted poste- 
riorly. Beneath are similar callosities, but the anterior edge is feebly indicated, the 
sides being most distinct. Thoracic feet minute, 3-jointed, small and rather short: 
third joint one-halt as thick as the second. Head : Clypeus very small, membran- 
ous; labruni small, narrow, though longer than wide, and well rounded in front ; 
mandibles solid, thick, rounded at tip; antennae 4-jointed, rather slender; second 
joint about one-half as long as the tirst and about one-quarter shorter than the third ; 
the fourth minute, slender, about two-thirds as loug as the third is wide. Maxillae 
with the lobe rather broad, not very hairy, extending as far as the end of the muxil- 
lary and labial palpi ; maxillary palpus 4-jointed; first joint much shorter than long, 
flattened, spherical ; second subspherical ; third one-half as long as the second ; fourth 
longer than the third, but only about one-half as thick. Mentuni narrow, about one- 
third as long as wide ; ligula long and narrow; labial palpi 3-jointed; first joint a 
little longer than thick ; second very short, spheroidal, a little less than one-third as 
long as first : third conical, considerably longer than the second and one-half as 
thick. Length, 12 mm ; length of prothoracic segment, 2 mm ; breadth, 3 mna ; breadth

The pupa is .44 inch long. It is tlattened and rather broad, and may be readily 
identified from the other pnpsB of the genus, as it has the characters of the species, 
viz, by the short an ten me, which do not extend quite as far as the hinder edge of the
