the rest of the body is much narrower, and tapers sh'ghtly towards the posterior extremity. 

 It is of a pale yellow colour, and has no feet. The pupa is at first whitish, but becomes darker 

 as the beetle develops. As noted above, the adult beetle is of a shining greenish black colour, 

 and has shorb stout legs. It may often be seen basking in the sunshine in summer, on the 

 sides of the trees and logs. The eggs of this insect are deposited early in summer in crevices, 

 and under the scales of the bark, being fastened in place by a glutinous substance. In a few 

 days the larva hatches and bores thcough the bark to the sapwood, in which it cuts broad, flat 

 channels, and sometimes completely girdles the tree. As it develops it bores farther into the 

 solid wood, and when fully grown again approaches the surface. When ready to become a 

 pupa, it gnaws partially through the bark, and then casts its last larval skin. About a fort- 

 night later the pupa changes to a beetle, which gnaws its way through the bark, and thus 

 completes the cycle of development. 



P .. The directions given above for the round-headed borer are also applicable to 



this insect. 



The Small Bark Borers (Magdalis cenescens), identified by Dr. Fletcher, are reported 



from all parts of the Lower Mainland, especially injurious on Vancouver and other islands. 



They are the larvae of small beetles of the weevil family (Curculionidm). 



B k §,"^ The larvse are found under the bark of apple trees, destroying the inner bark 



and young wood, usually several close together; sometimes they are so 



numerous that the entire bark of the trunk and principal limbs is infested with the larvse, 



and for all practical purposes the tree is valueless and had better be destroyed. 



The methods advised to prevent the ravages of the larger borers are advised to be used as 

 preventives; and as it is usually noticed that trees in an unthrifty condition are particularly 

 liable to be attacked, measures should be taken by drainage, cultivation and manuring to 

 induce a vigorous healthy growth of the trees. 



The Pea Weevil ( liruchus pisi) is reported from Poster's Bar and Lytton. The parent 

 beetle deposits eggs on ike outsides of the young pea-pods in summer. These hatch in a few 

 p ^^ .. days, and the larvse bore through the pods into the peas, which they enter 

 and eat out the substance of, leaving the germ, however, untouched. When 

 fudl-grown, the larvse eat holes on one side of the pea, leaving only the outer covering, before 

 entering the pupal state. Most of these remain' in the peas till the following spring, emerging 

 as the perfect beetle; but some complete their life cycle the same season. 



Seed peas infested with these pests should be enclosed in tight vessels, and a little bisul- 

 phide of carbon poured in, covering up closely. The fumes will destroy them. Another plan 

 has also been tried with good effect; this is to heat the peas, as soon as ripe, to a temperature 

 of 145° Pahrenheit, when the partially grown larvae will be killed without injuring the 

 germinating quality of the seed. 



On no account should peas infested with weevils be sown without treatment.
