LACKEY, or BARRED-TREE LACKEY MOTH (Clisio- 

 ca'mpa Neu'stria). " The eggs of this insect, in winter, 

 may be detected easily, in broad bands, round the twigs 

 of our pear, apple, and other trees. They are arranged 

 with such admirable art, that they seem set by the 

 skilful hands of the jeweller, and are very conspicuous. 

 Each bracelet, as the French gardeners call it, contains 

 from two hundred to three hundred eggs, fastened by 

 their ends, in a series of from fifteen to seventeen close, 

 spiral circles, round the twig. The spaces between the 

 eggs are filled up with a tenacious, brown gum, which 

 protects them from inclement weather, as well as from 

 all attacks except those of man. The eggs thus placed 

 look like a ring of seed-lac ; and we think its name may 

 have been thence derived. They are easily crushed by 

 the gardener's knife. The caterpillars striped length- 

 wise, blue, red, and yellow, slightly hairy, and with a 

 white line down the back appear from these eggs in 

 the April or May following. They congregate early in 

 the morning, or during rain, in large nests, at the forks 

 of the small branches, and are then easily crushed. 

 They enter the chrysalis state at the end of June, and 

 then they are to be found in cocoons, or oval webs, 

 powdered with white or yellowish dust, between two 

 leaves, &c. The chrysalis, or pupa, is longish, and dark 

 brown, in which state it remains for three weeks or a 

 month. In July the moth appears ; its colour is light 

 yellow or reddish-yellow-ochre. The upper wings have 

 a darker band across their middle, which band is bordered 

 by two light cross-lines ; the fringes of the wings are 

 whitish, spotted with brown ; the lower wings are of a 

 uniform brownish or light yellow colour. The male is 

 readily known from the female by his comb-like (pecti- 

 nated) antennae (feelers) and thinner body. The insect 

 flies only at night, and, consequently, is rarely seen. The 

 caterpillars often appear in considerable numbers, and 

 do not confine their ravages to fruit-trees, but attack 

 many others ; such as beeches, elms, poplars, oaks, and 

 even pines. In May, when the caterpillars are living in 

 society, the nests containing them should be collected 

 and destroyed. Care must be taken when collecting the 

 nest ; for, if the caterpillars are much disturbed, they let 

 themselves down to the ground by means of a thin, 

 silken thread, and escape. In July their cocoons should 

 be looked for on the trees, in the roofs of sheds, in hedges, 

 and even on the tops of walls." The Cottage Gardener,
