that species. As the insects of this genus vary in their size it is 
with considerable hesitation that I enter this as a distinct species, 
it corresponds so closely in its colors and other characters with 
the amca Say (nigricomis Le Conte). My examples of that species, 
however, have the exact dimensions assigned to it by Say and Le 
Conte (0.55), whilst all my examples of this species are more 
than a third larger. They moreover have the anterior as well as 
the middle shanks curved. 
To test the blistering qualities of this species three of the legs 
of a specimen nineteen years old were pulverized and mixed with 
a little cerate and bound upon my arm. In six hours the spot 
was as nicely vesicated as though the best Cantharides of the shops 
had been employed. 
The worm of the Codling moth (No. 48) and of the Plum 
weevil (No. 70) are as prone to infest the interior of pears as of 
apples. 
3. THE QUINCE .—Cydonia vulgaris. 
The only insects known to us as occurring upon the quince are 
the same that are found upon the apple, and also the Cherry slug 
worm, No. 92. Its worst enemy is the Apple tree borer (No. 2) 
which appears to prefer the quince to any other tree; and in dis¬ 
tricts where this insect abounds it is found to be almost impossible 
to grow this fruit.
