As our only purpose in this place is to deny the lepidopterous character of Palæontina, it is unnecessary to say anything in defence of the view we have expressed of its homopterous affinities; the superior position of the cell, the position and character of the lower cross veins (which we believe really traversed the entire wing), with their origin at the indentation of the lower border, suggest such a relationship, although there are not a few points in which it differs somewhat strikingly from living types. The discovery of a fossil in the cabinet of the Rev. Mr. Brodie, which was found in England at the same or nearly the same horizon, as _P. oolitica_, and which seems to be a pupa case of one of the Cicadida of rather unusual size, renders my suggestion more worthy of credence. At the conclusion of his latter paper Mr. Butler draws attention to the fact that Messrs. Westwood and Bates had expressed their agreement with his views. It should, however, be borne in mind, that, so far as appears from any facts which have been published, these gentlemen, whose well considered views upon the subject would unquestionably be of great weight, expressed this assent only upon a brief evening examination of a very obscure fossil in a poorly lighted hall, and before any one had questioned its lepidopterous character. FOOTNOTES [A] Probably an error for Tab. 5, fig. 28a, 28b, which seems to represent a Tenthredinidous larva. [B] The plate, however, is wanting, both in the copy belonging to the Smithsonian Institution and in that in the Library of the Boston Society of Natural History, so that I cannot tell whether it is copied from Boisduval’s figure or is an original.
