INJURIOUS INSECTS. 363 



and of a length to correspond to the size of the trees to be pro- 

 tected. When these are drawn closely about the tree they 

 should lap sufficiently to be tacked or nailed through the lap : 

 a hole should be made through one end of the tins with a 

 punch, then in placing the tins on the tree the end with the 

 hole should lap over the other end, and if a lath nail is used 

 this may be made by a smart blow to pass through the other 

 end, and into the tree. The nail should only be driven par- 

 tially in so as to be easily pulled out when the tins are to be 

 laid away. By making a narrow slit in the other end of the 

 tin to correspond with the hole when the tin is lapped, it can 

 be fastened by a common carpet tack, in which case the tack 

 should only be driven partially into the tree. Professor Tracy 

 recommends that the tin be tacked or nailed near the upper 

 edge. This tin is a sure preventive, for the cut-worm can not 

 pass over the surface of smooth tin. Judge Ramsdell would 

 have the tins longer, and fasten by hooking, as the ends are 

 bent for that purpose. He thinks there is little danger of the 

 larva passing between the band and tree. He uses these same 

 bands in fighting the peach-borer, as already described. 



As these pests work far worse on sandy land, those having 

 orchards on light soil will have to be specially vigilant. 



The Rose Chafer. Macrodactylus subspinosa, Fabr. 

 Family, Scarabeidce. Order, Coleoptera. As this old pest of the 

 rose is becoming quite destructive to the grape in various sec- 

 tions of our country I will give it brief attention. 



NATURAL HISTORY. Its history and habits closely resemble 

 those of its family relation, the May beetle, already described. 

 The beetles appear in June and July ; eat most ravenously, 

 seeming to relish rose leaves, grape leaves, and even cherry 

 leaves. After this wedding feast is over, the females lay their 

 eggs in the ground. The grubs feed on the roots of plants, but 

 are not sufficiently destructive to attract attention. The pupre 

 may be found in May, and in June the beetles come forth again. 



REMEDIES. As this beetle will, like the curculio and blister 

 beetles, fall from the plants whenever disturbed, they may be 

 shaken onto sheets placed under the vines, and destroyed.
