M. Lefebvre also found at Cosseir some very slender bones of a 

 cuttlefish which 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 Sejna elonr/ata, Paleont. Univers. t. 4. f, 7-10 (Ferussac 

 and D'Orb. Ccphal. t. 24. f. 7-10). 



There is a third species 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. Camillo Rondani. 



Rondani has found the larva of Tischeria complaneUa living in 

 oak-leaves, upon wliich its mines form spots similar to those pro- 

 duced by the larva? of some other Tineidae 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 bell-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 had 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 ; all furnished 

 at the sides with a few minute hairs. It lives between the epider- 

 mides on the parenchyma of the leaves of Quercus peduncidata 

 and perhaps other species. 



Simultaneously with the moths, a considerable number of minute 

 Hymenopterous parasites were produced from the leaves ; they feed 

 upon the larva? of the Tischeria, and destroy many of them. This 

 parasite belongs to the Chalcididae, and to the subfamily Encyrtinip ; 

 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
