ANNUAL REPORT OF NEW-YORK 
APPLE. LIMBS. 
Two other New-York species, very similar to this and doubtless 
having the same habits, may here be noticed. They are much 
less common, and are met with in the month of April. 
10 . Purblind snapping beetle, Alans myops, Fab. 
Brown, clouded with ash-gray, the eye-like spots much smaller 
dim, and oval instead of round. 
11. Blinking snapping beetle, Alaus luscus, Fab. 
Differs from the foregoing only in being wholly destitute of any 
gray or white coloring. 
The Divaricated Buprestis (see No. 71,) is sometimes met 
with upon decaying apple trees. 
AFFECTING THE LIMBS AND TWIGS. 
Mining the ttvigs internally causing them to perish. 
12. Apple twig borer, Bostrichusbicaudatus, Say. (Coleoptera Bostrichid®.) 
Particular twigs withering and their leaves turning brown in 
midsummer, with a hole the size of a knitting needle perforated 
at one of the buds some six or twelve inches below the tip end 
of the twig, this hole running into the heart of the twig, which is 
consumed some inches in length. 
The insect, a small cylindrical beetle, dark chesnut brown, 
black beneath, the fore part of its thorax rough from minute ele¬ 
vated points, and in the males furnished with two little horns, 
and the tips of their wing covers above, with two prickle-like 
points which curve inwards. Length 0.25 to 0.35. 
This insect occurs from Pennsylvania to Mississippi, and has 
been common of late years in the orchards of Michigan and Illi¬ 
nois, but has never been met with as yet in New-York or New- 
England. 
The blight beetle destroys the twigs similarly, perforating a 
minute hole at several of the buds instead of one only, but it is 
more common on the pear tree. See No. 56. 
The oak pruner, represented on plate ii., fig 2, in its larva 
state severs the small limbs, in summer, cutting them off as 
smoothly as though the work were done by a saw. It is rare on
