was elected a Fellow of the Society. 
Exhibitions. 
Mr. Merririetp exhibited some Melitea aurinia from 
Touraine forced and cooled as pupe, the latter being much the 
darker and more strongly marked, some Hwuch/loe cardamines 
from Sussex, those cooled having the apices of the wings darker 
and the discal spots smaller than those which have been forced, 
and some Colias edusa from eggs laid by two normal females 
taken in Savoy, two out of the five reared being of the var. 
helice ; the marginal border of one male, which had been forced, 
was very pale and much suffused with long yellow scales. He 
also showed four Papilio machaon ; two of them forced as 
pup, had their dark parts very pale and their tails long and 
slender, the two which had been cooled having the dark parts 
much extended in area and darkened in hue, their tails being 
short and broad. These results, which were to be obtained 
with winter as well as summer pupe, corresponded with 
those previously obtained by Dr. Standfuss. 
Mr. J. J. WALKER exhibited two winter nests of Porthesia 
chrysorrhea from the Isle of Sheppey, where the species had 
lately become very common. 
Dr. Mason exhibited a Buprestid larva found among 
Baltic timber at Burton-on-Trent. This had been among 
wood in a box since the beginning of July last, and there 
was scarcely a trace of frass. Marsham had recorded the 
escape of a larva of Buprestis splendens from the wood of a 
desk in the Guildhall, which had stood there for more than 
twenty years (Trans. Linn. Soc., x). It is probable that the 
growth is extraordinarily slow and consequently that the larva 
can maintain life for very long periods in most unfavourable 
conditions. 
Mr. BLanprorD called attention to similar cases which he
