I Hop vine Snout Moth. Pyralts rostralis, Linn.; Hypena rostralis, 1, caterpillar; 2, chrysalis; 3 and 4, moth. The caterpillars of this moth injure the Hop by feeding on the leaves. They are of a pale green colour, with clearer spots, and a whitish line on the sides and back; slender in shape and gradually smaller towards the head, and of the size figured above; and are distinguishable by having only three pairs of sucker-feet (in addition to the true feet on the rings next the head), and the pair of sucker-feet at the end of the tail. When full-fed the caterpillar draws a leaf partly together, and commonly changes to the chrysalis in a light cocoon which it spins within the folds. The moth, which appears in June and July, or earlier, is rather more than an inch in the spread of the wings, and is variable in colouring. In well-marked specimens the fore wings are greyish brown, darker from the base to about the middle, with a zigzag blackish streak across near the tip, and some raised tufts of black scales about the centre; the hinder part of the wings is palest. The hinder wings are brownish. The moths of this genus niav be generallv known Iw +.he snout-hke appearance of the front of the head, whence^'they take their name.—(* Illus. Brit. Ent
