and both pairs are deeply-fringed. There are two or three broods of this insect during 

 the year.

In addition to those enumerated, there are a score or two of species of insects which 

 are known to devour the leaves of the pine, in some instances injuring them very much. 

 Unfortunately it does not yet seem to be within the power of man to do much directly 

 towards limiting the destructive work of these enemies to our forests, yet this should not 

 deter us from studying their habits and life history, as a knowledge of these may help us 

 much more than we anticipate. A few trees, such as a belt or group planted for shelter 

 or ornament, may be protected from the leaf -destroyers by syringing them with a mixture 

 of Paris green and water, in the proportion of a teaspoonful of the poison to a pailful of 

 water. Bark lice may be killed by the use of alkaline washes applied with a brush or 

 broom ; such alkaline applications are also of use in preventing the borers from obtaining 

 a lodgement in the trees, as these insects will not usually deposit their eggs on trees so 

 protected ; but it is scarcely possible that such remedies can ever be applied over extensive 

 areas of forest. It is gratifying to know that in addition to the number devoured by 

 insectivorous birds, almost every injurious species is preyed on by predaceous and parasitic 

 insects, which seek out and destroy the pests with ceaseless diligence. Were it not for 

 these friendly species, the destructive insects would long ere this have rendered the growth 

 of trees an impossibility. 



THE CHINCH BVG—Micropus leucopterus. Say. 

 By Wm, Saunders, London, Ont. 



This formidable insect pest has recently appeared in force in the adjoining State of 

 New York, where it has within a limited area inflicted a very considerable amount of 

 damage. That an insect so enormously destructive as this one is in the west, has 

 domiciled itself so near us is sufficient to excite some alarm and induce our agriculturists 

 to be on the alert and to use such defensive measures, in case of attack, as the science of 

 economic entomology has suggested. 



During the last week in September a package of insects was forwarded to the New 

 York State Entomologist, with the following statement in regard to them, from Mr. M. H. 

 Smith, of Eedwood, Jefferson county, N.Y. : " I herewith transmit specimens of (to us)
