ination will show that they are covered with little six-sided 

 pits. 



The eggs are entirely unprotected, and yet they weather 

 the winter, hatching out in the spring about the time the 

 corn begins to grow. The full grown larva is nearly half 

 an inch long. It burrows into the roots of the corn, mining 

 lengthwise, and causing them to decay unless the season is 

 very wet. 



The worm pupates in August, in an oval cell in the 

 ground, and the beetle hatching out, commences to feed on 

 the pollen of the corn, frequently devouring the silk, and 

 if they are not too hard, the grains of corn also. 



As the Corn Root Worm always stays in the same locality, 

 and does not move about much, there is a very simple and 

 effective remedy against it, viz., the changing of crops, 

 which will soon start out the Root Worms. 



STRAWBERRY ROOT WORMS. 



There are three genera of Chrysomelidce, known as 

 Strawberry Root Worms, each occurring at different times, as 

 follows: 



Colaspis. April — June. 



Paria June — August. 



Scelodonta August — June. 



(Active from August — October. ) 



They much resemble the larva known as the crown 

 borer, but the latter is footless, and so they are easily dis- 

 tinguished from it. 



The eggs are laid in the ground at different periods of 

 the year, according to the species, the larvae feeding on the 

 roots of the strawberry leaves. 



The genus Scelodonta feed only on the strawberry.
