, is the number of brownish wart-like bodies that stud the young shoots and occasionally the margins on the underside of the leaves.[2] Each of these warts or scales is a transformed female, containing a large number of eggs which are hatched within it. [Footnote 1: The following notice of the "coffee-bug," and of the singularly destructive effects produced by it on the plants, has been prepared chiefly from a memoir presented to the Ceylon Government by the late Dr. Gardner, in which he traces the history of the insect from its first appearance in the coffee districts, until it had established itself more or less permanently in all the estates in full cultivation throughout the island.] [Footnote 2: See the annexed drawing, Fig. 1.] When the young ones come out from their nest, they run about over the plant like diminutive wood-lice, and at this period there is no apparent distinction between male and female. Shortly after being hatched the males seek the underside of the leaves, while the females prefer the young shoots as a place of abode. If the under surface of a leaf be examined, it will be found to be studded, particularly on its basil half, with minute yellowish-white specks of an oblong form.[1] These are the larvae of the males undergoing transformation into pupae, beneath their own skins; some of these specks are always in a more advanced state than the others, the full-grown ones being whitish and scarcely a line long. Some of this size are translucent, the insect having escaped; the darker ones still retain it within, of an oblong form, with the rudiment of a wing on each side attached to the lower part of the thorax and closely applied to the sides; the legs are six in number, the four hind ones being directed backwards, the anterior forwards (a peculiarity not common in other insects); the two antennae are also inclined backwards, and from the tail protrude three short bristles, the middle one thinner and longer than the rest. [Footnote 1: Figs. 2, and 3 and 5 in the engraving, where these and all the other figures are considerably enlarged.] When the transformation is complete, the mature insect makes its way from beneath the pellucid case[1], all its organs having then attained their full size: the head is sub-globular, with two rather prominent black eyes, and two antennae, each with eleven joints, hairy throughout, and a tuft of rather longer hairs at the apices; the legs are also covered w
