[719] I have reason to think that the larvæ of some species of Hemerobius thus protect themselves by a net-like case of silken threads; at least I found one to-day (December 3d, 1816) inclosed in a case of this description concealed under the bark of a tree: and it is not very likely that it could be a cocoon, both because the inhabitant was not a pupa, which state, according to Reaumur, is assumed soon after the cocoon is fabricated (iii. 385); and because the same author describes the cocoons of these insects as perfectly spherical and of a very close texture (384); while this was oblong, and the net-work with rather wide meshes.

[723] Lesser, L. .256.—Lyonet inserts a note to explain that Lesser's remark is to be understood only of such insects as live in societies; and adds, that solitary species do not assemble to pass the winter together. Lesser, however, says nothing about these insects passing the winter together, as his translator erroneously understands him; but merely that they assemble as if preparing to retire for the winter, which my own observations, as above, confirm. His expression in the original German is, "gleichsam als wenn sie sich zu ihrer winter-ruhe fertig machen wolten." Edit. Frankfurt und Leipsig 1738, p. 152.
