Curator of the Botanic Garden, Sydney, New South Wales.- Prof. Westwood dis- 
covered two species of Coccus upon the branches, but was unable to detect anything 
but mould upon the fruit. 
Mr. Stainton exhibited a collection of Micro-Lepidoptera obtained from the larve 
which he had collected whilst at Cannes and Mentone in February and March: the 
collection comprised upwards of thirty species, amongst which may be specially 
mentioned a fine series of Depressaria rutana, from larve on Ruta angustifolia on the 
rocks at Monaco; a specimen of Phibalocera quercana, bred from Arbutus; two spe- 
cies of Gelechia, bred from larve feeding on Silene Niczensis, and forming sand- 
cocoons amongst the roots of that plant (one species being probably identical with our 
G. marmorea) ; a new species of Zelleria, allied to Z. hepariella, for which M. Milliére 
proposes the name of Phillyrella, bred from the flowers of Phillyrea angustifolia; and 
a Nepticula, bred from the cork-tree. Mr. Stainton remarked that, in addition to the 
species bred, there were a number of different larve which he failed to rear, and 
among them was another species of Nepticula on the cork-tree with a very peculiar 
mine. 
The Hon. Thomas De Grey exhibited Eupecilia anthemidana and E. rupicola 
from Norfolk; and mentioned that he had on the previous day captured in Kent five 
specimens of Hypercallia Christierninana. 
Mr, A. R. Wallace exhibited a collection of Malayan Cetoniida, in illustration of 
the paper mentioned below.

“Observations on Dzierzon’s Theory of Reproduction in the Honey-bee,” by 
Mr. John Lowe, of Edinburgh. With a view to test the truth of the theory that “ all 
eggs which come to maturity in the two ovaries of a queen-bee are only of one and 
the same type, which when they are laid without coming in contact with the male 
semen, become developed into male bees, but, on the contrary, when they are fertilized 
by male semen, produce female bees,” from which theory, if true, we might, in the 
words of Von Siebold, “expect beforehand that by the copulation of a unicolorous 
blackish brown German and a reddish brown Italian bee, the mixture of the two races 
would only be expressed in the hybrid females or workers, but not in the drones, 
which, as proceeding from unfecundated eggs, must remain purely German or 
purely Italian, according as the queen selected for the production of hybrids belonged 
to the German or Italian race,” the writer set to work to obtain hybrids between Apis 
mellifica and Apis Ligustica, and also between Apis mellifica and Apis fasciata, and 
the result of his experiments was that Ligurian queen-bees fertilized by English 
drones and Egyptian queen-bees fertilized by English drones, both produced 
drones which, as well as the workers, were hybrid in their characters, and 
bore unmistakeable evidence of the influence of the male parent. From this 
the Author drew the conclusion that the eggs of a queen-bee which has been fer- 
tilized by a drone of another race, whether they develope into drones or workers, 
are in some way affected by the act of fecundation, and that both sexes of the progeny 
partake of the paternal and maternal character or race; from which it followed that 
Dzierzon’s was not the true theory of reproduction in the honey-bee. Specimens of 
the hybrids were exhibited to the Meeting, and Mr. Frederick Smith (who did not 
consider Apis Ligustica to be specifically distinct from Apis mellifica), after an
