JANUARY 25, 1875 (ANNIVERSARY MEETING). 
Sir Sidney Smith Saunders, C.M.G., President, in the 
chair. 
[After the usual review of the state of the Society, and 
obituary notices of Prof. Zetterstedt, Dr. Herrich-Scheffer, 
George Robert Crotch, Francis Walker, Dr. Antoine Dours, 
and John Traherne Moggridge, the President gave the 
following lucid and instructive summary of the progress of 
Economic Entomology on the Continent of Europe, in the 
United States, and in England, alluding to the several 
subjects of “ Phylloxera of the Vine,” “Colorado Potato- 
beetle,” “ Bee-Keeping,’ “ Economy of White Ants,” 
“Economy of Stingless Bees,” “Habits of Social Hyme- 
noptera,” and “Fertilization of Flowers by Insects,” as 
follows :—] 
The Phylloxera of the Vine.—The ravages of the Phyl- 
loxera Vastatrix, and the remarkable incidents connected 
with the life-history of this minute but formidable enemy of 
the viticulturists, have been the subject of many interesting 
communications to the Académie des Sciences of Paris, and 
to the French Entomological Society, during the past year. 
Among the innumerable remedies which have been advo- 
cated and tested as a means of checking the progress of this 
scourge, the only treatment hitherto recognised as absolutely 
effective is the submersion of the vineyards, where prac- 
ticable, during one month in winter, which has been attended 
with perfect success. The principal facts ascertained in 
connexion with the biology of these destructive Homoptera 
may not be undeserving of some notice, considering the vast 
proportions which their propagation and extension have now 
assumed. The young larve, which hybernate on the roots 
of the vine, whether derived from the autumnal sexual races 
adverted to in the sequel, or (as it would seem) from ante- 
cedent broods, commence laying eggs in the early spring, 
their progeny producing and reproducing in continuous 
succession by agamogenesis, as usual among the Aphides, 
though, unlike these, always oviparous. Among these 
successive broods some individuals never acquire wings;
