Mining the leaves of difterent species of pine, a minute, brown, narrow, cylindricallarva. For several years the leaves of the common pitch pine {Pinns rigida)in the vicinity of Ithaca, N. Y., have been seen to be extensively minedby the larvae of a Tineid, the life history of which we have first studiedthe present season. The end of the leaf, and in many cases the entire 794 FIFTH EEPORT OF THE ENTOMOLOGICAL COMMISSION. leaf above its base, becomes dead and brown, and when opened it isfound to be entirely eaten out, and to contain, in the proper season, thelarva or pupa of the above-mentioned Fig. 269.—The pine leaf miner, larva, pupa, adult, and -work.—After Comstock. What are in all probability the eggs of this insect have been founddeposited singly near the base of the leaves. They are nearly round,flattened on the side of attachment, and slightly so on the opposite average diameter is °^™ (.05 inch). The general color is reddishbrown, differing in intensity wich the stage of development. The sur-face of each egg is marked with numerous delicate carinae, which meetat the center, somewhat resembling those of the cotton and boll wormsfigured in the article on cotton insects. We have not proof positivethat these are the eggs of this leaf miner, but their size, appearance,and place of deposit seem to indicate that they are. The work of the growing larvae is well shown in the plate, and alsothe
