Tlu! head of the larva is thin, flat and circular, with the mandibles t'orming an appendage in front on the median line similar to some of the JJtItocollctis larvae. The body tapers somewhat posteriorly? with the sides of the segments slightly ])rojecting find flattened, with the general form rather cyliiub-ical. It is without feet or pro- legs, and is very inactive, making little or no voluntary motion when removed from the mine, aiid does not retreat in its mine when touched. The body is somewhat viscid. The mine is a linear tract just wide enough to accommo- date the body, long and winding. The larva does not con- sume all the parenchyma of the leaf along its tract, but simply separates the upper ej)idermis, so that it is not trans- ])arcnt. When full grown the end of th(i mine is enlarged, and the cocoon woven in a little i)ucker of the leaf within the mine. The perfect insect is very sluggish, at rest carrying its antenna? thrown backward, but arched somewhat above the dorsal surface. P. vitigencUd* Antenna} brownish-silvery, fuscous at the tip.
