I have not been able to find, even with Mr. Brodie’s help, the first specimen referred to; but an examination of the original of the latter (see fig. 3) proved that, while it is unquestionably an insect, it cannot be referred to the Lepidoptera; the punctures referred to are both too large and much too irregularly disposed to have been the points of insertion of the scales; they are probably the marks of the insertion of hairs, such as are not uncommonly seen irregularly scattered over the wings of insects belonging to the other suborders. As the figure of the first species closely resembles in this particular the one I have seen, I am forced to the conclusion that neither of these wings are lepidopterous. Plainly, the only reason why a new generic name was appended to these forms was that their remains were too fragmentary to afford the slightest guess as to what modern genus they might be referred. The fossils came from the English Purbecks. 2. _Palæontina oolitica_ BUTL. The first notice I find of this remarkable and very interesting fossil is that published in various literary and scientific London journals reporting remarks given at a meeting of the Entomological Society of London, and which afterward appeared as follows in their Proceedings:[AZ] “Mr. Butler exhibited a remarkably perfect impression of the wing of a fossil butterfly in the Stonesfield slate. It appeared to be most nearly allied to the now existing South American genus Caligo.” [Illustration: Fig. 4. Palæontina oolitica Butl. The neuration, after Butler’s first sketch.] A full description of this insect soon appeared in the author’s “Lepidoptera Exotica,” accompanied by a plate; both were afterward republished in the “Geological Magazine.” In fig. 4 we reproduce fig. 1 of his plates, representing the neuration of Palæontina; and in fig. 5, fig. 2 of his plates, subsequently copied by “The Graphic.” A description of the genus and species is first given, which it is unnecessary to reproduce here; afterward, the following remarks: “[126] Though a British insect, this species belongs to a group so completely tropical that I do not hesitate to describe and figure it in the present work; its nearest allies are the genera Caligo, Dasyophthalma and Brassolis, all three essentially tropical American genera.
