Exhibitions, dc. 



Mr. F. Moore exhibited, at the request of Sir W. H. Gregory, late 

 Governor of Ceylon, a large series of beautifully executed drawings, 

 by native artists, of the transformations of the Lepidoptera of that island. 

 These drawings were made under the supervision of Dr. Thwaites, and 

 represent the life-history of many species hitherto unknown. Mr. Moore 

 expressed a hope that the Government of Ceylon would accede to the 

 proposition of having them published. 



Mr. M'Lachlan exhibited four parts — relating to Entomology — of the 

 great Russian work, Fedtschenko's ' Travels in Turkestan ; ' they consisted 

 of two parts on Hymenoptera, &c., one on Coleoptera, and one on Arachnida.

 drawn, engraved, and coloured in Russia. 



Mr. H. Goss exhibited a small collection of fossil insects obtained by 

 Mr. J. S. Gardner, F.G.S., from the Bournemouth Leaf-beds (Middle

 p. 265), I remarked upon the variations of tint in some Pieridoe according 

 to season. I wish now to point out that Cape specimens of P. Severina 

 show in the female a tendency to vary on the fore-wing from a minute spot 

 at the extremity of the discoidal cell to a broad bar extending thence from 

 the costa. In thirty-eight specimens in my collection the mode in which 

 this occurs is well illustrated. At first a slight dark projection occurs on 

 the costa, while the discoidal spot is at the same time sometimes enlarged. 

 In other examples an intermediate dark marking occurs, until at last all 

 these markings become united in a dark band. In one specimen exhibited
