Carlisle and Chattenden, the former were lighter in colour of 
underside and not nearly so rich as the latter, four of the 
former were either var. avete or nearly approached that form ; 
one example of the curious larva of Heterogenea limacodes from 
Westerham; and larve of Acidalia immorata from ova laid 
by a female taken in the Southern Alps. Referring to the 
latter, Mr. Turner remarked on their undoubted Acidalia- 
like appearance and habits. Mr. Tutt said that from the 
imaginal appearance he had at first considered the species 
a Strenia, allied to S. clathrata. But he observed that the 
egg had also an undoubted Acidalid form, and was very 
different from that of S. clathrata, which was well distin- 
guished by being studded with white knobs. 
Mr. Manger exhibited specimens of the extremely large 
land shell, Achatina variegata, from Ibadan, near Lagos, 
West Coast of Africa. They were six inches across the 
mouth, and specimens were known which measured as 
much as eight inches. The natives prized this mollusc 
as an article of food. He stated that the eggs were more 
than one inch in diameter, and possessed a calcareous 
shell. 
Mr. West, of Greenwich, exhibited specimens of a local 
Hemipteron, Dictyonota fuliginosa, taken on broom at Plum- 
stead. 
Mr. R. Adkin exhibited series of Satyrus semele from East- 
bourne and Bournemouth, also examples set in their natural 
resting positions and affixed to an artificial background to 
illustrate the manner in which the insect on alighting 
obtains protection by assuming a position that caused it to 
harmonise with the rough ground on which it was wont to 
rest. 
Mr. Tutt remarked that the Continental allied species had 
precisely similar habits. 
Mr. Lucas exhibited specimens and drawings of the 
dragon-fly Agrzon mercuriale, and communicated the fol- 
lowing notes : 
‘“On August 3rd last I came across a colony in the New 
Forest of the very scarce little dragon-fly, Agrion mercuriale, 
of which I exhibit a male and a female specimen. Mr. 
McLachlan found this insect rather commonly in a certain 
locality in the New Forest in 1868, but could not find it 
again till last year, when he succeeded in taking eight. The 
locality from which the present specimens came can hardly 
be the same as that known to Mr. McLachlan, as the stream 
over which they fly is a perennial one, where they would
