130 INDIAN CORN CULTURE. 



White ff rub {Lachnosterna fusca, Frohl). This 

 is the larva of the common btown May beetle 

 or June bug. The beetles deposit small, whit- 

 ish eggs about the roots of grass which in. about 

 a month hatch into small, brown-headed grubs 

 that feed on the roots about them. During the 

 second year the grubs work near the surface 

 and reach their full growth during the sj)ring 

 of the third or fourth year. They are most 

 abundaiit in old grass lands, and when this is 

 plowed for one or two seasons may work great 

 damage to the corn which may be planted on it. 

 This is a difficult insect to exterminate. Fall 

 plowing is no doubt advantageous. Pasturing 

 land in the late summer and fall with pigs will 

 be a means of getting rid of many, then plow- 

 ing during the late fall or spring.
