when approached. The President remarked on the interesting 

 nature of this exhibition, and stated as his belief that many 

 AcridiidcB and LocuatldiB voluntarily took a bath by leaping on to 

 the surface of streams and swimmiug to the bank after a short 

 time. 



Mr. Kirby exhibited, on behalf of Mr. Ralfe, who was present 

 as a visitor, a series of very remarkable specimens of Lycccna 

 corydon, and the President, Mr. Weir, and others made remarks 

 thereon. 



The Rev. W. W. Fowler exhibited the second recorded British 

 example of the beetle, Harpalus calceatus, taken by himself at 

 Bridlington, Yorksliire; also Apion Lemoroi (Brisout), a new 

 French Apion, taken on the coasts of Normandy and Brittany 

 on Poli/(/o)iuni avkulare ; and he observed that it was likely to be 

 found on our southern coasts, if looked for. He also exhibited 

 several species of British Helophori, and read notes on their 

 synonymy.

Mr. H. Goss read the following analysis of M. Brongniart's 

 recent work on ' Les Insectes Fossiles des Terrains Primaires,'* 

 which he had prepared at the request of M. Brongniart: — 



After some preliminary remarks on Palaeozoic insects, and the 

 large number recently discovered near Commentry, the author 

 referred to the proposed classi6cation of insects by Packard and 

 Scudder into two series, — Metahola and Heteroinetahola, — the 

 former including insects with a complete metamorphosis, such 

 as the Lepidoptera, Diptera, and Hymenoptera, and the latter 

 consisting of insects for the most part with incomplete metamor- 

 phosis, i. e., the Hemiptera, Neuroptera, and Orthoptera, the 

 Coleoptera being in Brongniart's opinion an intermediate group, 

 or, if placed amongst the Heterometabola, are to be regarded as in 

 course of progression towards the Metahola. It was observed that 

 all the insects known from Palseozoic rocks belong to the section 

 Heterometabola, and the classification of Packard and Scudder is 

 therefore the one which best accords with the data of Palaeontology 

 and Embryology. In this paper M. Brongniart enumerates in 

 the order of their apparition the known Pahieozoic forms, and, 

 after briefly alluding to the Silurian Blatta and the Devonian
