Ride of the same segment ; with them is a projecting horn shorter than the middle one. 

 He named it Cephaloniscus Grayanus, in compliment to the keeper of the zoological 

 collections at the British Museum. Mr. White also made some remarks on the order 

 Isopoda. 



Mr. Stainton exhibited, on behalf of tha Rev. H. A. Pickard, a specimen of 

 Plutella Annulatella, remarkable as having been taken in a new locality, the Isle of 

 Portland, and as being much whiter than ordinary specimens. The only previous 

 localities in this country recorded for this insect, were the North of England (near 

 Newcastle- on-Tyne), the North of Ireland and Scotland ; from the greater contrast 

 of colour in this Portland specimen, it was far prettier than the northern form of the 

 species. 



Dr. Allchin exhibited a large Noctua allied to Catocala, said to have been taken 

 near Bolton, Lancashire; he had been unable to identify it with any species 

 contained in the extensive general collection of Nocture in the British Museum. 



Mr. Walker made the following remarks : — "At a former Meeting, on the occasion 

 of the exhibition of a horn-shaped gall inhabited by a Thrips, discovered by 

 Mr. Foxcroft, at Sierra Leone, I observed that it resembled the horn-shaped gall of 

 the lime-leaf, and that I had not discovered the insect which is the cause of the latter 

 excrescence ; but I have since found that its history has been investigated long ago 

 by the botanist under-mentioned : — 'Observations Physiologiques sur le development 

 des gales corniculees de la feuille de tilleul de Hollande, et sur la cause qui les 

 produit. Par P. J. F. Turpin.' (Mem. Acad. Roy. Sci. Institut. Fr. vi. 1835)." He 

 noticed that it was inhabited by a mite, which he named Sarcoptes Gallarum Tiliae, 

 and of which he traced the development from the egg to the perfect insect. He 

 observes that it is not certain whether the mite is the cause of the formation of the 

 gall, in which it does not occur before the middle of May nor after the middle 

 of August, and, therefore, its mode of life during nine months of the year is 

 still unknown. Another horn-shaped gall appears on the leaves of the beech, and is 

 quite distinct from the pyramidal gall lately mentioned here as the habitation 

 of Ocidomyia Fagi. 



Mr. Smith communicated a paper intituled " A Contribution to the History of 

 Stylops, with an enumeration of such species of Exotic Hymenoptera as have been 

 found to be attacked by these parasites." 



Mr. Waterhouse read the following papers: — "A List of the British Species of 

 Latridius." " A Revision of the British Species of Corticaria." 



Part ix. of the current volume of the Society's 'Transactions,' published in 

 December, was on the table. — E. S. 



York Entomological Society. — At the Anniversary Meeting of this Society, held 

 on the 3rd of January, 1859, the Rev. F. O. Morris was elected President; Mr. J. 

 Birks, Treasurer ; and Mr. R. Anderson, Secretary, to whom all communications may 

 be addressed at his residence, Coney Street, York.
