an inch long, white, with a horny, yellow head. It changes 

 to a pnpa within the root, from which the beetle escapes dur- 

 ing the month of August. 



The beetle, shown at b and c in the figure, is about one- 

 sixth of an inch long, of a browu color, with several more 

 or less distinct dark-brown spots, and is marked with lines 

 and dots. 



Almost all the plants infested with this larva are sure to 

 })erish, and old beds are said to be more liable to injury than 

 new ones. The only remedy suggested is to dig up and burn 

 the plants after the fruiting season is over, and before the larva 

 has time to pass through its transformation and escape as a 

 'j.-eils. 



ATTACKING THE LEAVES. 

 No. 192. — The Strawberry Leaf-roller. 



Phoxopleris complana Frol. 



Tliis insect, which is sometimes designated the strawberry 

 leaf-roller, is not the only leaf-roller which attacks the leaves 

 of the strawberry. The caterpillars belonging to the early 

 brood are found upon the plants during the month of June, 

 rolling the leaves into cylindrical cases, fastening them with 

 threads of silk, and feeding within on their pulpy substance, 

 causing the leaves to appear discolored and partly withered. 

 They are about one-third of an inch long, and vary in color 

 from yellowish brown to a darker brown or green. The head is 

 yellowish and horny, with a dark eye-like spot on each side. 

 The second segment has a shield above, colored and polished 

 like the hes-d, and on every segment there are a few pale 

 dots, from each of which arises a single hair. In Fig. 335, 

 a represents the larva of its natural size, b a magnified view 

 of the head and four succeeding segments, and d the terminal 

 segmen't of the body. 



The larva becomes a chrysalis within the folded leaf late in
