The. Exhibition of " Other Orders." 



Mr. Ashdown exhibited three boxes containing varieties and 

 aberrations of Cocrinellida, comprising : — 



1. About 20 different forms of Adalia bipunctata. 



2. A very large number of Coccinella 10-piinMata showing a great 

 range of aberration, from spotless examples to specimens with 

 coalesced spots and blotches, and also several dwarf and some very 

 large forms. 



3. Many forms of Coccinella hierogbjphica showing a similarly 

 large range of aberration from spotless forms to a specimen in 

 which the thorax was entirely black. 



Mr. R. Adkin exhibited a weathered flint that he had found on 

 the Downs near Eastbourne, and which so closely resembled a 

 mushroom in general appearance that, when in an upright position 

 one might easily have been tempted to gather it as such. 



Mr. West (Ashtead) exhibited the living larva of a stag-beetle, 

 Liicanus cervus. 



Mr. West (Greenwich) exhibited five drawers of his collection 

 of Coleoptera, including his very fine series of Cocchiellidce, 

 Chryso)iieiid(t', Endo^injchida', Brucliidcn, Scarabaidce, LucanidcB, 

 etc. Among the LucanidcB was a fine series of Lucanus cervus, the 

 stag-beetle, showing extremes of size, the largest J measuring from 

 the point of the antlers to the tip of the elytra just 3^- inches, while 

 the smaller measured If inches. 



As a contrast some of the Trich<)jiteri/i/iilae\\ere exhibited to show
