 an inch long, the male somewhat smaller, of a glossy- 

 black, the first two pairs of legs being yellowish, with 

 blackish thighs. The transparent wings are iridescent, 

 the front pair haying a smoky tinge across the middle. 

 They lay their eggs in little incisions made in the skin 

 of the leaf. This insect is often very injurious in the 

 older States, and is extending westward, and is frequent 

 in Canada. 



RE3IEDIES. — Dry air-slaked lime, if sprinkled from a

 attached to a pole, has been found very effective. It has

THE PEACH-BORER. 

 {^geria exitiosa, Say.) 



This borer is quite common, and the greatest insect

From the Round-headed Apple-Tree Borer, to which 

 it bears some resemblance, both in its mode of work, and 

 general appearance, it is at once distinguished by having 

 six scaly, and ten fleshy legs. It works also more gen- 

 erally under the surface of the ground, and goes through 

 its transformations within a year, though worms of two 

 or three sizes may be found at almost any season. When 

 full grown, the worm spins for itself a follicle of silk, 

 mixed with gum and excrement, from which in due time
