Exhibitions, ^c. 



Mr. Stevens exhibited a magnificent collection of Coleoptera, made by the late 

 M. Mouhot among the mountains of Lao, in the interior of Cochin-China ; it included 

 some splendid Buprestidae, about 150 species of Longicorns, &c., and a very large 

 number of novelties. He regretted to have to state that M. Mouhot's exertions in the 

 cause of Science had brought on a fever which resulted in his death. 



Mr. Stainton exhibited specimens of Gracilaria semifascia, bred from maple-leaves 

 obtained near Mickleham, on which the larvae raised small, blunt, conical excres- 

 cences. Mr. Stainton having remarked upon the tendency of this insect to produce 

 verdigris on the pin, the President suggested the use of a pin dipped into varnish, and 

 allowed to dry before it was used. 



Mr. Wallace exhibited photographic figures of Coleoptera : plates of Lucani, of 

 the natural size, were conspicuously successful ; other insects of smaller size, but 

 magnified twice in linear dimensions, were not so successful. Mr. Wallace called 

 attention to the mode of mounting these smaller species on pieces of gelatine instead 

 of cardboard : this rendered the use of gum unnecessary, since all that was requisite 

 to fix the insect was to moisten the under side ; moreover, the gelatine was so trans- 

 parent that the under side of the insect was available for examination. 



The President exhibited two rare Staphylinidae, — Myrmedonia Haworthii and 

 Heliobates propinqua, — both captured by his son, Mr. Edward Smith, on Keigate 

 Common, on the occasion of the Society's excursion on the 8th ultimo. 



The President also exhibited an imperfect hermaphrodite of Apis mellifica, which 

 had been sent from Scotland, and read the following description thereof :—
