5. The belted chion. 
Chion oinctus (Drury). 
Order Coleoptera; Family Cerambycid.e. 
This worm, like the preceding and with probably similar habits, forms 
long galleries in the trunk in the direction of the fibers 
of the wood, producing a more flattened long-horned 
beetle from two- thirds to a little over an inch long, of 
a hazel-brown color, with a short dull straw-yellow 
band placed obliquely forward of the middle of each 
wing cover, and with a small sharp spine on each side 
of the prothorax, and two slender ones on the tips of 
each wing-cover; the antennae of the males are more 
than twice the length of the body. ( Harris.) Fi * m -- The belted

6. The discoidal saperda. 
Saperdq discoidea (Fabricius). 
Order Coleoptera ; family Cerambycid,e. 
Not only did Dr. Fitch report this beetle as boring in hickory, but 
Drs. Le Oonte and Riley have also bred it from this tree. 
This grub is a similar but much smaller worm than the foregoing, 
changing to a cylindrical long- horned beetle of a black or blackish- 
brown color, clothed with ash-gray pubescence which is less dense 
above and commonly forms three gray stripes upon the thorax, and a 
band or crescent upon the middle of the wing-covers, its legs yellow or 
reddish. Length .40 to .60 inch. (Fitch.) 
7. The hickory borer. 
Cyllene picta (Drury). 
Boring in the trunk of the hickory, a whitish worm, one-half an inch long, the 
beetle appearing in June. (See Locust tree borer.) 
We have received this insect in all its stages from Mr. H. Gillman, of 
Detroit, who several years ago found a few of them in a hickory log 
March 10. From these living specimens 
the following description was drawn up : 
Larva. — Body thick; mouth-parts black; head 
redd.sh behind the antennse. Prothoracic seg- 
ment (first bohind the head) large and broad, 
being one-half as long as broad ; flat and broad 
above, the upper surface being lower than that 
of the succeeding segment; the anterior edge 
thickened, being slightly corneous ; a mesial 
deeply impressed line, especially on the hinder 
two-thirds, where it becomes a broad, deep, angular furrow, dividing the tergum into 
two quadrant-shaped halves ; the outer edge of the segment rises above the flattened

nat. size; a, larva; b, pupa.-— From
