724 FIFTH REPORT OP THE ENTOMOLOGICAL COMMISSION. 
It will be seen that the rudimentary feet of the early embryo have dis- 
appeared. When the Larvae hatch. as soon as they are free from the shell, 
according to Dr. (lissler's observations, they attach themselves to the 
surface of the bark in the manner seen at Pig. 1254 a, and turn around 
for half an hour before beginning to feed. Fig. 254 b represents one of 
these larva- at this time. Pig. 254 o, was drawn by Dr. Gisslerto repre- 
sent the end of the body of one of these larv;e, to show the form of the 
infra-anal sucker-like extremity of the last abdominal segment, which 
is produced and soft at the end, with perhaps temporary dermal glands 
to secrete an adhesive fluid. The anus is ^v\\ to project above and 
beyond this sucker, r representing the rectum, i the intestine, and st 
the pyloric end of the stomach.* 
53. Thk goal-black hylastes. 
Hylastes porculus Er. (carbonarius Fitch). 
A beetle so closely like the preceding that it merits to be noticed in 
connection therewith is the Hylastes carbonarius of my cabinet. It is 
0.20 long, of a pure black color, except its feet and antennae, which are 
chestnut red. Its face shows no transverse depression iuferiorly, but 
has an elevated line along the middle, reaching a third of its length. 
The smooth line along the middle of the thorax is less distinct than in 
the foregoing species, being slightly if at all elevated, and the punct- 
ures of this part are more coarse. Its wing- covers are not bearded 
posteriorly, and its general form is plainly more narrow and slender 
than that of the Pine Hylastes. The only specimen I have seen was 
captured the middle of July in the yard in front of my dwelling. (Fitch.) 
54. The pales weevil. 
Hylobius pales Herbst. 
Order Coleoptera; family Curculionid.e. 
A large dark-chestnut colored or black weevil, 0.30 to 0.40 long, sprinkled over 
more or less with dots, whereof one on the middle of the outer side of tho wing-covers 
is more bright, these dots being formed by fine short yellowish gray-hairs. Quite 
common in May and June among pine trees, and in mill yards, and on piles of pine 
lumber; with its long cylindrical snout perforating the bark and crowding an egg 
into the hole, the larva from which, similar in its appearance to that of the white- 
pine weevil, burrows beneath the bark, loosening it from the wood. (Harris's Trea- 
tise, p. 61.) 
This is a very common pine insect, which ranges from Maine and 
Lake Superior to Florida. LeConte states that the head is very 
densely, though not coarsely, punctured, and is nearly opaque; the
