MAPLE BOKERS. 387 
on the metathoracic segment is of a double lunoid shape. The first 
abdominal segment has a short, narrow dorsal area, shorter than the 
one on the preceding segmeut. The lateral linear crescent-shaped im- 
pressed hues are well marked. 
This larva differs from that of Chrysobothris femorata in being con- 
siderably larger, the abdominal segments being thicker in proportion 
to the prothorax, and also in the style of sculpturing on the prothorax. 
The apex of the V * s surrounded by a square, deeper-colored area; the 
disk on the under side is divided by a double line, which widens sud- 
denly in front into halves. 
9. The quercitron bark-borer. 
Graphisurus fasciatus (De Geer). 
Order Coleoptera ; family Cerambycice. 
This beetle, more commonly found on the oak, has been found in the 
pupa as well as adult stage under the bark of the sugar maple in North- 
ern New York by Mr. George Hunt; and we have reared the b°etle 
from a pupa found under the bark of the red or swamp maple, at 
Providence, June 1. The cell made by the larva for the repose of the 
pupa is about an inch long, one-third of an inch wide, and one-tenth 
deep. (See also p. 71.) 
10. Xyloterus politus Say . 
Order Coleoptera ; family Scolytid^e. 
In this species, according to Leconte, the elytra have ill-defined dis- 
tant rows of punctures, with interspaces equally strongly punctured, 
pubescence erect and abundant. He has received specimens from Dr. 
J. A. Lintner, said by him to depredate on maple trees. " It is easily 
known," adds Leconte, " by being more hairy than the other species, 
with the interspaces of the elytra sparsely punctured, so that the rows 
of punctures appear confused." 
11. Bellamira scalaris Say. 
This longicorn has been taken by Mr. Harrington in the act of ovi- 
positing in a maple stump in July. It also attacks the birch. 
The beetle. — Head contracted behind the eyes to form a neck ; thorax narrow ; 
wing-covers pubescent, glistening, rather wide at the base, but tapering rapidly 
behind, and shorter than the abdomen. Reddish, with yellowish antennas and feet. 
Length, 25 mm to 30 mm . 
12. The white ant. 
Termes flavipes Kollar. 
The following copy of an article by Br. H. A. Hagen (Can. Ent., xvii, 
p. 134) shows that this insect, usually only destructive to rotten wood, 
may rarely attack living trees.
