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.
