724 FIFTH REPORT OF 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. Gissler's observations, they attach themselves to the 

 surface of the bark in the manner seen at Fig. 254 a, and turn around 

 for half an hour before beginning to feed. Fig. 254 b represents one of 

 these larvsB at this time. Fig. 254 c, was drawn by Dr. Gissler to repre- 

 sent the end of the body of one of these larvte, 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 seen to project above and 

 beyond this sucker, r representing the rectum, i the intestine, and st 

 the pyloric end of the stomach.* 



53. The coal-black hylastes. 

 Hylaates porculu8 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 inferiorly, 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. 



Hylobiua pales Herbst. 



Order Colkoptera; family CuRCULiONiDiE. 



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 onter side of the 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
