indication. M. de Laferte, Monogr. des Anthicites, 149 (1848), rem arlcs " that the 

 individuals from the shores of the ocean are generally paler than those from the 

 eastern countries of Europe, and that those from the coasts of France and Belgium 

 are entirely destitute of the discoidal spot." 



Mr. Janson also exhibited the following rare species: — 



Philonthus fuscus, Grav. Taken by himself in a boletus on an ash, near Hornsey, 

 Middlesex, on the 19th ultimo. 



Oxylaemus cylindricus, Panz., Eric. Found by Turner about ten days since, in 

 bark of oak in the New Forest, near Brockenhurst. 



Tomicus monographus, F. The male, apparently very rare, conspicuous by having 

 the anterior margin of the thorax triangularly produced with the apex recurved ; 

 found by Turner at the same time and under the same circumstances as the foregoing. 

 Erichson (Naturgesch. d. Ins. Deutschl. iii. 284, 1845), adds to his description of 

 Oxylaemus cylindricus: " In oaks, rare. Found by Professor Ratzeburg and myself 

 in the burrows of Bostrichus monographus." It is therefore interesting to find the 

 two species associated in this country. 



Platydema violaceum, F. Likewise taken by Turner, under bark of oaks, at the 

 same time and in the same locality as the two preceding. 



The President remarked that he had himself taken Philonthus fuscus, under 

 bark of trees infested by the larvae of Cossus ligniperda, and Mr. Shepherd staled that 

 he also had met with this species in similar situations. 



Mr. Sealy exhibited a beautiful series of varieties of Colias Edusa, including the 

 white female variety (Helice, Hub.), and examples forming links from it to the typical 

 insect: also a specimen of Sphinx Pinastri, said to have been captured by a young 

 entomologist whilst flying about a fir-tree at Romsey, Hants. 



The President remarked that, with the exception of the specimens said to have 

 been received by the late Dr. Leach many years ago from the neighbourhood of 

 Edinburtjh, there was no record of the capture of this species in Britain, although so 

 abundant in many parts of Europe ; he inquired of Mr. Sealy whether there was any 

 likelihood of the specimen exhibited being a foreign example which had been 

 inadvertently placed amongst insects from the locality mentioned. 



Mr. Sealy replied that the reputed captor had some time previously visited 

 Switzerland, and there taken a few insects, but he was assured that the S. Pinastri 

 was not one of the Swiss captures; moreover, he (Mr. Sealy) believed that country 

 was not a locality for S. Pinastri. 



Mr. Stainton observed that Mr. Sealy was mistaken, as the insect is well known 

 in Switzerland ; it was, however, only fair to state that from his knowledge of 

 the habits of S. Pinastri on the Continent, he considered the neighbourhood of Rom- 

 sey a very likely spot for the occurrence of this species. 



Mr. Stevens exhibited specimens of four species of Lomaptera sent from Batchian 

 by Mr. A. R. Wallace ; he also communicated the following by Mr. A. R. Wallace : — 



Note on the Sexual Differences in the Genus Lomaptera. 



" Lacordaire says in his ' Genera ' that the Lomapterae ofier no sexual distinctions, 

 except slight variations in the legs; and in the generic character he adds ' the fore 

 legs are three-toothed in both sexes or in the females only.' In four species of the 

 genus which I have recently taken in the Gilolo group of islands, I have, however, 

 observed very strongly marked sexual differences, and I have had the good fortune to
