Miscellaneous. 359 M. Lefebvre also found at Cosseir some very slender bones of a cuttlefish whicli have the inner surface elevated into a central ridge as in >S^. Lefebvrei, and which D'Orbigny has described and figured under the name of Sepia elongata, Paleont. Univers. t. 4. f. 7-10 (Ferussac and D'Orb. Cephal. t. 24. f, 7-10). There is a third S2)ecies in the British Museum with the central prominence, found on the coast of Australia, which I have described as Sepia apama, Gray, Cat. Cephal. Antepedia, p. 104, var. 10. The Larva of Tischeria complaneUa and its Parasite. By Prof. Camilio Rondani. Eondani has found the larva of Tischeria complaneUa living in oak-leaves, upon which its mines form spots similar to those pro-duced by the larvae of some other Tineidse and those of Orchestia quercus. The leaves were brought to him by a friend, who wished to know by what insect the spots were produced. They were placed under a beU-glass, and in a few days two specimens of Tischeria complaneUa were observed endeavouring to make their escape. Other specimens continued to make their appearance until the end of July, the first having been observed about the middle of that month. On examining the mines, most of the insects were found in the pupa-state ; but some larvae were discovered which bad died without any apparent cause ; and these, when placed in a vessel of water, acquired nearly the appearance which they must have possessed when alive. From the specimens thus swelled the author prepared the following description of the larva : — The larva is footless or with indistinct feet, the sides being rugu-lose or tubercular to replace those organs. Head coriaceous, ferru-ginous, the following segments very pale yellowish and somewhat translucent, except the last, which are confused into one large fer-ruginous piece ; first or cephalic segment broader, marked above with a large, subquadrate, blackish spot ; the remainder with a yellowish or brownish-yellow dorsal longitudinal vitta ; aU furnished at the sides with a few minute hairs. It lives between the epider-mides on the parenchyma of the leaves of Quercus pedunculata and perhaps other species. Simultaneously with the moths, a considerable number of minute Hymenopterous parasites were produced from the leaves ; they feed upon the larvae of the Tischeria, and destroy many of them. This parasite belongs to the Chalcididae, and to the subfamily Encyrtince ; but the author was unable to refer it to any of the genera of that group with the characters of which he was acquainted. As Mr. Haliday concurred with him in regarding it as a new generic type, he has characterized it as follows, under the name of TiNEOPHAGA, nov. gen. Antennae 7-articulatae, sen scapo et articulis 6 flageUi instructae in utroque sexu ; prime articulo flageili brevi, caeteris in foemina
