PEAR. QUINCE. 



that species. As tlie 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 cmea Say {nigricornis Le Conte) . My examples of that species, 

 however, have the exact dimensions assigned to it by Say and Le 

 Conte (0.55), Avhilst 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 houi'S 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.— Ct/(f(mza 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.
