210 THE CANADIAN ENTOMOLOGIST. 



chiefly during the night and hide in the day time among the roots and 

 stalks of the plants. When full grown the larva spins a small cocoon, 

 which is usually placed a httle below the surface of the ground, m which 

 it changes to a chrysalis : about three weeks later the beetle escapes. From 

 observations which have been made on this insect at the Department of 

 Agriculture, in Washuigton, the average period required from the time of 

 the depositing of the egg to the escape of the mature beetle is three and 

 one-third months, hence in most localities there will be two broods dunng 

 the summer Mr. A. H. Kilman, one of our members residing in Ridge- 

 way was the first to report the occurrence of this pest in Ontario which 

 he says was wafted to our shores by prevaiUng east winds, about the loth 

 of August last. On this date the beetles appeared on the opposite side of 

 Lake Erie in Buffalo, in such multitudes that thousands of them were 

 crushed on the pavements by the feet of passers by. Mr. Kilman says : 

 " I picked them from the fences and sidewalks, and found them m the 

 grass in my lawn ; I am of opinion that they will go into winter quarters 

 here and open up a lively campaign in the spring. Whatever the sequel 

 may show, I fear these invaders will prove of better staying qualities than 

 those who crossed the border in '66, and turned to the right about at 

 Ridgeway because Canada was not the 'clover patch' they were looking 

 for." 



As the larvae will be found most numerous in the latter part of May or 

 early in Tune, it is recommended that the clover should be heavily rol ed 

 a that time L the purpose of destroying them. If badly infested fields 

 were ploughed about this period, the destruction of the insects would be 

 still more cerlain. 



Early in the summer alarming accounts were received of another in- 

 sect injuring the maple trees, especially the shade trees on streets and 

 venue's. Tl-s was a species of Coccus or bark-louse />..«-
