22 INSECTS INJURIOUS TO FOREST AND SHADE TREES. 
Riley thinks that the larva lives but a single year, although larve of 
different sizes occur in midwinter with the beetles. 
The larva.—Length, 0.55-0.75 inch; diameter in middle of body, 0.05 inch. Body 
almost straight, cylindrical, 12-jointed, with a few faint hairs only on prothorax and 
around anus; thoracic joints short, bent a little forward, swollen and broadly and 
deeply wrinkled, with two especially prominent swellings on top of joints 2 and 3, 
converging towards head, and having each a granulated rufous spot; the other joints 
with about three dorsal transverse wrinkles; joints 5-9 subequal, as long as 1-3 to- 
gether, twice as long as 4; 10-12 diminishing in length, slightly swollen, the anus 
retracted; 6 very small 3-jointed thoracic legs, the terminal joint being a mere bristle ; 
stigmata quite distinct and brown, the first pair much the largest, between the fold 
of joints 2 and 3; the others on anterior fifth of joints 4-11, the last pair more dorsal 
than the rest. Head pale yellow, darker around mouth; rounded, more or less bent 
over the breast, with sparse, stiff, pale hairs springing from elevated points; ocelli, 
none; antennie not vislble, unless a dusky prominence lying close between mandibles 
and maxillie be calied such; labium small, with two depressions and other inequali- 
ties, the margins slightly angular, allowing jaws to closely fit around it; jaws stout, 
triangular, the inner margin produced at middle into a larger and smaller tooth, and 
with a slight excavation near tip; maxille long, with but a short, horny cardinal 
piece, the palpi apparently 2-jointed and with difficulty resolved, on account of three 
or four other prominences around them; garnished on the inside with a close row of 
stiff hairs and on the outside with two stouter hairs; labium large, oboval, the palpi 
placed in front and 2-jointed. 
Pupa.—Average length 0.40 inch, with the antenne curled back over the thorax, 
the seven or eight terminal joints each with a more or less distinct, forwardly-directed, 
brown thorn ; the snout lying on the breast and varying according to sex ; abdominal 
joints with a more or less distinct row of small thorns on the. posterior dorsal edge, 
the last joint with a more prominent thorn directed backwards in a line with the 
body. (Riley.) 
7. THE GRAY-SIDED OAK WEEVIL, 
Pandeletius hilaris Herbst. 
Order COLEOPTERA ; family CURCULIONID#. 
Making a smaller burrow than that of the Northern Brenthian, a worm like that ot 
the plum weevil and changing to a gray weevil found on the leaves from May to Sep- 
tember. 
Beyond the fact stated by Harris that the larva lives in the trunks of 
white oaks, on which the beetles occur from late in May to September, 
we know nothing of this insect. 
The beetle.—A little pale-brown beetle, variegated with gray upon the sides. Its 
snout is short, broad, and slightly furrowed in the middle; there are three blackish 
stripes on the thorax, between which are two of a light-gray color; the wing-covers 
have a broad stripe of light gray on the outer side, edged within by a slender blackish 
line, and sending two short oblique branches almost across each wing-cover; and 
the fore legs are larger than the others. Length from 4 to} of aninch. (Harris.) 
8. Tuk QUERCITRON BARK-BORER. 
Graphisurus fasciatus De Geer. 
Order COLEOPTERA ; family CERAMBYCID. 
Feeding upon and destroying the quercitron bark of newly-felled trees, forming 
large tracks filled with worm-dust, a white, footless grub about 0.60 inch long, and 
with a transverse oval tawny-yellow spot on the middle of each wing above and be-
