as the Editor suggests that it was doubtless at rest on the tree, and not 

 feeding. — John Poetee, Jun., 8, East Street, Lewes, December 14th., 1857. 



Nottingham Natural History Society. — "We are glad to find by a letter 

 from Mr. J. H. Wood, that this Society is in a prosperous condition. On 

 the 17th. of November an excellent paper was read by Mr. Morley, on 

 Lepidopterous Insects, which contained much interesting information, and 

 many observations especially valuable to the student. The meetings are held 

 weekly, when a paper is read upon some subject connected with Natural 

 History — these papers being for the most part the result of the writer's 

 personal experience and observation. This is the right principle to act upon, 

 and we wish the Society every success. We shall be glad at any time to 

 receive a report embodying any original facts brought before the Society. 



Cambridge Entomological Society. — The November meeting of this Society 

 was held on Friday, the 27th. ult., at the Secretary's rooms; F. Barlow, 

 Esq., Vice President, in the chair. The following are the names of the 

 members balloted for and elected: — F. Stainforth, Esq., Queen's College; Mr. 

 L. Cumming, Cambridge; H. S. Bainbridge, Esq., St. John's College; F. H. 

 Knapp, Esq., Pembroke College. — Mr. Preston read a paper on the structural 

 differences observable in the several stages of Lepidopterous insects. Passing 

 over the varied forms of the egg, Mr. Preston commenced by a description of 

 the structure of the larva; he sketched the various organs of the head and 

 trunk, with the abdomen; he dwelt at some length on the structure of 

 the mouth. Respecting the internal organization the author noticed in suc- 

 cession the nervous, the digestive, the circulatory, the respiratory, and the 

 muscular systems. Pointing out the arrangement in each, and especially the 

 wonderful development of the last-mentioned in the larvae of insects. Mr. 

 Preston then enumerated the various changes that the organs of insects under- 

 went in passing through the pupa stage to that of the imago. The parts of the 

 body of the imago then were described and their purposes explained. Several 

 diagrams were exhibited as illustrative of the subject. — After the chairman 

 had tendered the thanks of the meeting, an interesting discussion arose from 

 some questions put by Mr. Dunning, Mr. Bree, and Mr. Crewe, regarding the 

 sensations of insects. — The "vexed question," as to the advisability of keeping 

 pupse dry or moist, was also discussed. — Mr. Brown exhibited M. peltigera, 

 taken near Newmarket; also very pale varieties of Ncenia typica and Pascilo- 

 phasia marginaria, and two specimens of Dosithea eburnata. — Mr. Barlow 

 exhibited a splendid insect nearly black, which was said to be a variety of 

 Galleria cereana, also a fine series of cereana which were distributed. — Mr. 

 Crewe exhibited a box of Eupithecice. — Mr. Preston exhibited Cynips aptera. 

 — Mr. Sealy exhibited a series of L. callunce, collected in Pomona, Orkney, 

 during the past summer. The meeting broke up at half-past ten.
