134 THE CANADIAN HORTICULTURIST. 



The Apricot Plum is a large greenisli-yellow plum, measuring 6| 

 inches in cfe'cumfererxe, and has a very small stone. 



The County of Peterborough can by no means claim exemption 

 from the ravages of injurious insects. 



The Galeruoa vittata, commonly called the Cucumber Beetle, 

 appeared on my melon vines in June, in far greater ^abundance than 

 usual. Being unlike the Potato Beetle, exceedingl}^ active and very 

 wide-awake, it is not so easily captured as its larger and more formid- 

 able congener. On approaching a bed, those beetles that a.re on the 

 surface of the leaves, either fly rapidly away or run beneath the leaves, 

 and dropping to the ground, quickly make their escape. I found the 

 best method of capturing them was by the careful manipulation of a 

 small butterfly net. 



Another small beetle that attacked the grape vines about the same 

 time, was one of the flea-beetles, the Haltica chulyhea. This beetle 

 destroys the buds as well as the leaves of the vines. These beetles 

 are also pretty active, although not so much so as the Galeruca. As 

 their name indicates, they hop as well as fly, but I caught the majority 

 of those 1 fourfd in my garden without much difficulty. They, like 

 the Cucumber Beetles, are very conspicuous in appearance, varying in 

 color from a glossy blue of difi'erent shades to a green, and measuring 

 nearly one-fifth of an inch. 



The Codlin Moth, Carpocapsa pomonella, an unwelcome imme- 

 grant from the " Old Country," is a constant visitant. Numbers of the 

 caterpillars may be captured by pinning a piece of old cloth around 

 the trunks of the trees at a short distance from the ground early in 

 the summer, and destroying the lai'VCB that have found shelter there 

 day by day. 



The Pear-tree Slug, the larva of one of the saw flies, Seland/ria 

 Cerasi, is an occasional visitor, although I have not found them 

 during the present season. They feed on the surface of the leaves of 

 pear, cherry and plum trees, and thus, the lungs being destroyed, the 

 trees ultimately perish, or at all events are unable to mature their fruit 



Last year, during my absence from home in August, the gaudy red- 

 humped caterpillar, the larva of the notodonta concinna, defoliated a 

 flourishing specimen of the Pomme Grise apple tree which I had 

 received from our Association.
