As against this insect the arsenites are indicated, or, where only a few plants are to be protected, hand-picking may be resorted to. In vineyards there may be often seen feeding on the under sides of the leaves little, black-spotted, yellow, sbmewhat hairy larvce, less than half an inch in length, ranged side by side as closely as possible, and retreating as they eat until a leaf is com- pletely skeletonized. When this kind of larva is full grown it spins a white, flattened cocoon, in which it changes to a pupa and from which it emerges in due time as a little, narrow- winged, black moth wearing a red collar. This is the Harrisina
