A. New London correspondent says: " I send by this mail to your address, a box containing leaves of Paris Daisy, which have been tunneled on the upper surface by an insect which you will find transformed in its tunnels on the leaf. I did not see it in the grub state. It is new here, the men had shifted the plants without noticing it, and in passing I thought at first that they had soiled the leaves with damp soil. It had wisely, for its own advantage, chosen the fleshy leaves on the young plants - old plants with small leaves are not much injured. I have picked every infected leaf and had it burned, hoping to stamp it out - keeping a few under a bell glass to find out what the perfect insect is. I have seen similar tunnels sparingly on cinerarias long ago, and at times on broad-leaved plants in the open air, but the runs were larger than those; possibly this is a smaller species of the same family".

[Prof. Riley considers them a dipterous leaf-miner of the genus Oscinis. But we have since observed that the insect has been noticed in Europe on these plants. It is probably introduced here from the Old World. - Ed. G. M].
