Exhibitions, dc. 
Mr. Higgins exhibited collections of exotic insects from Natal and 
Borneo. In the former were magnificent examples of several of the larger 
South-African Bombyces, bred from the larve; and he also exhibited a 
series of figures of these larve, executed by what was described to him as a 
«chromo-photographic process,” the figures having evidently been obtaimed 
by means of photography, and presenting their natural colours. 
Mr. Meek exhibited the example of Nyssia lapponaria (male) of Boisduval, 
recorded in the ‘ Entomologist’s Monthly Magazine,’ vol. vil. p. 282, as 
having been recently taken by Mr. Warrington at Rannoch, Perthshire, 
new to the British Fauna. 
Prof. Westwood exhibited a collection of varieties of British Lepidoptera, 
obtained by Mr. Briggs from an old collection formed in the time of 
Haworth. Among them were singular forms of Lycena dispar, Leucophasia 
sinapis, Lithosia helveola, &c. 
The Rev. R. P. Murray exhibited a series of Lepidoptera captured in 
Switzerland, including an example of Lyczena Euridice (said by Staudinger 
to be a form of Hippothée), in which the spots of the under side formed 
long streaks. 
Mr. Bicknell (on behalf of Mr. Cowan, who was present as a visitor) 
exhibited an extraordinary specimen of Gonepteryx rhamni, captured by 
Mr. Cowan at Beckenham, in March, 1870. This example was a male of 
the ordinary form, but the costal margin of each anterior wing was broadly, 
but unequally, suffused with bright rose-colour or scarlet, and the right 
posterior wing was marked in a like manner. 
Mr. M‘Lachian suggested that possibly the wings of the insect had come 
in contact with some substance during hybernation, which had chemically 
altered the coloration. 
Mr. Janson said he had noticed that yellow insects killed by cyanide of 
potassium became red. 
Mr. Cowan said the individual exhibited had been killed by chloroform, 
and moreover it was in precisely the same condition when captured. 
Mr. Bicknell also exhibited varieties of other British Lepidoptera. 
Mr. Stainton exhibited beautifully-executed coloured figures of the mines 
of various Micro-Lepidoptera, collected at Santa Marta, by Baron Von 
Nolcken, who had proceeded upon an entomological expedition to New 
Granada. 
Mr. Champion exhibited Scydmenus rufus, Mill. dé Kunze, a beetle new 
to the British list, recently captured by him in Richmond Park, as recorded 
in the ‘ Entomologist’s Monthly Magazine,’ vol. vil. p. 273. 
Mr. M‘Lachlan exhibited a tusk of an Indian elephant, placed in his 
hands by Dr. Sclater, accompanied by the following explanatory note,
