The perfect insect is a small, narrow, brown and greymoth, about seven lines across the wings when expanded(see Fig. 1a). The larva is of a pinkish colour, size as given at Fig. 5,slightly enlarged. Although there exists much difference of opinion as tohow the tubers of the potato are first attacked, I mustagree entirely with M. Ragouet, of Paris (as quoted byMr. Meyrick), that the eggs are laid on the young shootsof the plant; that the larvae, as soon as hatched, eat intothe root stock and descend until they reach a tuber; andthat they remain in this, eating ga
