the adults in size and in having a smaller number of body 

 segments and fewer legs. 



In New York a common and troublesome species is Jidiis 

 cocruleocindus Wood. It is nearly an inch in length and has 



})een found in- 

 jurious to peas, 

 beans, tomatoes, 

 melons and many 

 other vegetables 

 (Fig. 214). 



No satisfactory 

 method for the 

 control of milli- 

 pedes under field 

 or garden condi- 

 tions has been 

 devised. In the 

 garden they may 

 be trapped under pieces of boards or slices of vegetables 

 laid on the ground. In the greenhouse they may be trapped 

 in the same way or by using lumps of dough sweetened with 

 molasses. Lime or tobacco dust applied around the plants 

 will have a tendency to keep the pest away.

White Grubs 



Lachnosterna (several species) 



Vegetable crops are often seriously injured by large white 

 curved grubs that are found in land that has recently been in 

 sod. These grubs (Fig. 215) are the larval form of the large 

 brown June beetles or June bugs (Fig. 21()) that come blundering 

 around lights on sunnner evenings. In the United States 

 there are nearly one hundred species, but the greater part of 

 the injury is caused by a relatively small number.
