3")ec. 1897] Webster: Notes on Coleoptera. 201 fold has some mealy bloom ; dorsum covered with long tufts of white down which is secreted slowly after each molt, in long, flattened masses, two dorsal, two subdorsal, three lateral, the posterior one lower ; sub-dorsal tufts longer than the unpaired dorsal ones. The wool may be-come 5 mm. long and curls a little. Three stages observed with widths of head i.t, 1.5 and 2.1 mm. Ultimate Stage. — Head 2.1 mm. Perfectly smooth, uniform opaque yellowish white, head shining and a shade darker, eye black. Segments indistinctly transversely wrinkled. Body robust, thick, as high as wide ; thorax very slightly enlarged. Food-Plant. — Butternut. Found at Greenwood Lake, N. J. Dr. Packard has confounded this species with Monophadnus caryce Norton (5th Rept. U. S. Ent. Comm., 339). Fitch's butternut larvae, on being bred, prove to belong to Eriocampa, and moreover they differ from the hickory larvae of Norton in being blackish, while the latter •are described as greenish beneath the wool. NOTES ON VARIOUS SPECIES OF COLEOPTERA. plate X. By F. W. Webster. It has always appeared to me as a good plan to record the little, detached observations that are made by almost every observing ento-mologist. Taken individually, these are very often almost devoid of scientific value, but we all of us know how much light some point, of itself unimportant, will throw upon the problem of a life history, when we attempt to work this out, or construct it from the known facts at our disposal. It is as if a huge piece of chinaware were to be dashed into an infinite number of fragments, and these scattered broadcast over the land, and the attempt then made to bring these fragments together, and from them construct the piece anew. It would probably occur that many pieces would have to await the discovery of one, and again, a piece would fit fairly well into the wrong place, and the error could only be detected by the right fragment finally turning up and indicating its proper place. Sorrie of these notes have been, in the main, recorded elsewhere, but without illustration ; and it seems to me to be a matter of mutual benefit to have, somewhere, as accurate illustrations of as many of our species as possible.
