made. Favorable or unfavorable weather will explain, at least in part, 

 why sonje buds are cut off, while others remain attached. 



The entire time consumed varies greatly, but fifteen or even ten min- 

 utes, is ample for oviposition. The process of forming a hole consists 

 simply in perforating the corolla, although the calyx is also sometimes 

 pierced through, the time varying from two to five or more minutes. 

 In inserting the egg less than a minute is ordinarily consumed, and the 

 process of severing the bud varies in time according to how completely 

 the insect does its work. 



INJURIOUS APPEARANCES. 



The strawberry weevil appears to be one of the many forms, like the 

 corn bill bugs, for example, that are only exceptionally injurious, which 

 appear in great abundance for one or more seasons in certain districts, 

 and after causing a vast amount of trouble relapse into obscurity, to 

 reappear in a new locality after a lapse of years. A review of economic 

 literature, however, together with reports from correspondents, shows 

 that this insect has done more or less damage in the past, year after 

 year, since its first recorded appearance in 1871. It is more than prob- 

 able that the strawberry and blackberry crops, at least of this vicinity, 

 are annually levied upon by this little creature to the extent of from 5 

 to 20 per cent, a loss that would seldom be noticed. 



Now that our local growers are becoming familiar with the appear- 

 ance of the insect and its work, we should be better able to observe its 

 progress, as well as to cope with it in years of abundance. 



The following table shows that the insect has been more or less inju- 

 rious for the past twelve years:
