J98 GLOMETRA DEJOIUAKIA. 



is as large again as that of the winter moth. Its bioad I'ore-vvings are 

 of a reddish yellow, covered with many blackish dots. From the an- 

 terior border, not far from the tips of the wings, a dark wavy line stretch- 

 es across through these dots to the posterior border. Near to this line, 

 almost in the middle of the wings, is a black dot. The under wings 

 are a dirty white, doled with brown, and in the middle of the wings is 

 a black dot. The female has no wings, is much larger than that of the 

 winter moth, and has no rudiments of wings. The head and body are 

 M'hitish, covered with black streaks and dots, and the feet annulated with 

 yellow and black. 



This caterpillar is very destructive to the foliage of fruit trees in 

 certain years, often coming in succession, when it appears in great num- 

 ber.<!, as is sometimes the case. As a single female of this insect lays 

 about 200 eggs, the caterpillars of a few females are sufficient, if they 

 all live, to strip a fruit tree entirely of its leaves, particularly if it is a 

 young one. It is not easy to take these caterpillars, because they live 

 singly, and are scattered about on the fruit trees, and it is not till they 

 are nearly full-grown, and have partly stripped the tree, that they attract 

 the eye. But the female moths are easily kept from the trees, when 

 they are provided with a w^ooden boot, frame or box, daubed on the out- 

 side with tar or cart grease. This frame consists of four boards about 

 a foot high, and rather longer than the diameter of the tree they are to 

 surround. These four boards are to be nailed together in the form of 

 a square open box, but the fourth board is not to be fastened on till the 

 frame is placed round the tree, as the stem must be entirely enclosed by 

 the boards. To pievent the sun or rain from having any effect on the 

 tar or cart-grease, the top of the frame is to be surrounded with a mould- 

 ing; that is, a thin piece of wood three or four inches broad is to be 

 nailed on the top, so as to form a projection on the outside, and under 

 this an angle. This angle, formed on the outside only, is to be thickly 

 smeared with tar. This frame may thus be called a boot, as the stem 

 of the fruit tree stands as if in a boot. It must be set an inch deep in 

 the earth, which must be well trodden in round it, so that the moths 

 may not get under it and reach the tree. The boot ought not to be made 

 too large ; but should be so fixed as to allow of but little space between 

 it and the stem, that it may be more certain that no pupae or chrysalids of 

 the moth lie between the boot, and consequently very near the trunk. 

 This boot must be put in use about the end of October. At first it must 

 be smeared 2 or 3 times, to keep it from drying into the wood. In the 

 spring it must be daubed again — and again in April. The female moths 

 come out the latter part of autumn, and as lliey arc without wings, they
