120 INSECTS INJURIOUS TO THE APPLE. 



There is a conspicuous black spot near the fringe, from which 

 arises a pencil of black hairs. 



The larva (Fig. 118), which feeds on apple- leaves, is small, 

 flattened, and of a green color. It constructs from the skin 



of the leaf a flattened, oval case, in 

 Fig. 118. J^ig. 119. vvhich it lives ; the case is open at each 



^y^^'T/jS [ end, and is drawn about by the larva 

 \ as it moves from place to place. The 

 case is represented in Fig. 119. (Both 

 ^ case and larva are mac^nified.) The 

 larva becomes full grow^n about the 

 end of August, and attaches its cocoon to the bark of the tree 

 on which it is feeding, changing there to a chrysalis, in which 

 condition it remains until the following spring. 



No. 55. — The Rosy Hispa. 



Odontota rosea (Weber). 



This is a small, flat, rough, coarsely-punctated beetle, its 

 wing-covers forming an oblong square, as shown in Fig. 120; 

 there are three smooth, raised, longitudinal lines on each of 

 them, spotted with red, while the spaces between 

 Fig. 120. are deeply punctated with double rows of dots. 

 The head is small, the antennae short, thickened 

 towards the end, and the thorax rough above, 

 striped with deep red on each side. The under 

 side of the body is usually darker in color, some- 

 times blackish. This beetle is found from the 

 latter part of May until the middle of June, and 

 deposits its eggs on the leaves of the apple-tree. These are 

 small, rough, and of a blackish color, fastened to the surface 

 of the leaves, sometimes singly and sometimes in clusters of 

 four or five. 



The larvae, w\hen hatched, eat their way into the interior 

 of the leaf, where they feed upon its green, pulpy substance, 

 leaving the skin above and below entire, which soon turns 

 brow^n and dry, forming a blister-like spot. The larva, when
