until after the June meeting. The Council did not make any condition of exchange, 

 but they hoped the Members would, in return, contribute as far as they were able the 

 desiderata to the Society's collection. 



Proposed Catalogue of British Coleoptera. 

 The Secretary also said he was happy to announce that the offer of Dr. Gray for a 

 Synonymic Catalogue of British Coleoptera had been accepted by our Curator, Mr. 

 Jauson, who would be glad to receive any information and assistance from his brother 

 Coleopterists in the work he had undertaken. The first part of the Catalogue would 

 be ready in about two months, and it was also Mr. Janson's intention eventually to 

 print a Nomenclature of the Species, for interchange among collectors. 



Exhibitions. 



Mr. Foxcroft sent for exhibition specimens of several species of Lepidoptera, re- 

 cently reared by him from larvae collected in Fifeshire; a pair of each species would 

 be given to each of his subscribers for Lepidoptera : also two specimens of Papilio 

 Machaon, with the skins of the chrysalides from which they came: both insects and 

 pupag, he said in a note, presented certain constant differences of marking divisible 

 into two kinds, of each of which he had reared males and females. 



Mr. Bond exhibited a Phragmatobia lubricipeda, presenting an agglomeration of 

 the dark spots on the costa into a continuous line, and also some other variations of 

 marking. This specimen was reared by Mr. Foxcroft. 



Mr. Stevens exhibited, from the collection of Madame Pfeiffer, a pair of the rare 

 beetle Euchirus longimanus. 



Greasiness of Insects. 



Mr. Stainton exhibited two specimens of Nepticula Acetosae, pinned last summer, 

 which already showed signs of verdigris on the pins. 



Mr. Edward Sheppard exhibited four specimens of a Donacia, two of which were 

 mounted on gilt and two on ungilt pins. They were all pinned at the same time, four 

 months ago, and the gilt pins exhibited no trace of verdigris, but the ungilt pins were 

 surrounded with it. 



Mr. Edwin Shepherd repeated his former remark, that after the lapse of a year or 

 more he had found pins doubly gilt were affected by the greasiness of the insects 

 equally with ungilt pins. 



Description of a New Ornithoptera. 



Mr. Stevens read a description, by Mr. Wallace, of a new butterfly taken by him 

 on the N. W. coast of Borneo, under the name of Ornithoptera Brookiana, of which 

 a drawing was exhibited. 



Tropical Micro- Lepidoptera. 



Mr. Stevens read an extract from a letter received from Mr. Wallace, in Borneo, 

 in which he stated that he had taken about 700 Micro-Lepidoptera, among which are 

 some extraordinary developments of palpi, &c. He finds these small moths come in 

 abundance to a lamp, on dark, wet nights, and in the wet season he is sure he could 

 get thousands of thein.
