Forest entomology . hey passthe winter, being perfectly im-mune to the effects of soon as the young larchneedles burst forth in spring the larvae wake up, carry their casesback to the needles, and commence feeding in real earnest, thus giv-ing rise to the characteristic withering already referred to. Thelarvae now grow very rapidly, and the original cases become too tiny caterpillar then makes a fresh case. The larvae are a dark red-brown colour, and still darker head. Onlythe anterior pair of legs are at all moderately developed, and, withthe exception of one anal pair of pro-legs, with which they fix them-selves in the case, the pro-legs are also but poorly developed. Thereis a black plate on the anal segment. The larva is about 5 mm. long. The pupa is small and brownish-black. When the wings of the perfect insect are expanded they measureabout 4 or 5 lines across. The head and anterior wings are grey, theposterior wings of a paler grey, and the abdomen of a blackish grey.(Fig. 270.). 270.—Coleophora larieella. (From F. V. Theo-balds Animal Pests of Forest Trees.)a, pupal case ; b, moth. 284 FOREST ENTOMOLOGY. COLEOPHORA FUSCEDINELLA, Zell. This species is, as a rule, very common on alder, and is termed thealder-bud moth, in consequence of the larva? feeding on the buds anddestroying them prior to forming its case, and then on the leaves. COLEOPHORA Sp. Some years ago I received from my friend, Mr Elder Cholmondeley,Cheshire, a quantity of birch twigs which had been utterly destroyedby a species of Goleophora. So far this species has not been defin-itely identified. Fig. 271 is a representation of the damage, and the
