This is the insect previously mentioned in these papers as Leucanthiza Ornatella. At first I was inclined to place it in Lithocolletis, but a consideration of some of its peculiarities induced me to place it provisionally in DR. Clemens genus, Leucanthiza. On examination of the neuration of the wings, however, and of aome other points in its structure and habits, it seems to me to belong more properly to Lithocolletis, though it differs from it in some respects and approaches Leucanthiza, and more remotely, Phyllocnistis and Lyonetia.

Anterior wings rich chocolate - brown with creamy white stripes or markings. Costal margin lighter brown. A broad line running from the base of the median vein nearly to the posterior angle, where it becomes slightly forked; from this proceeds a slightly curved narrower branch, from the centre of the wing nearly to the costal edge, and one-third the distance from the apex ; a zigzag mark composed of three straight lines, the first being the broadest, and the third one-half the length of the others, proceeds from the outer angle, where it joins the first line, and terminates under the costal edge; the whole forming a distinct W crossed at the top by the transverse band. Inner edge faintly marked with creamy white.

Sometime during the latter part of July last, while wandering about the outskirts of a large potato patch, and examining the damage caused by the Coloroado beetle. I found on the vines the larva of a beetle belonging tothe family of Coccinellidæ or Lady Birds. The insect was new to me and although there were no larvaæ of the Colorado beetle in the immediate vicinity, yet I was in hope that I had discovered a new enemy of our abominable pest. To test the question more at leisure, I took my newly-found treasure home, and placed it in a box, wherein were numerous specimens of Colorado larvæ in all stages, from the diabolical looking little monster just hatched from the egg, to the full-grown, fat, and repulsive larva dragging its bloated body slowly about in search of some convenient place to undergo the transformation into the pupal state.
