it commonly here on the male flowers of the oak. Its occur- 
rence first in a northern locality, and in a southern one when 
looked for, must tend to show that it is widely distributed 
over the country, and would no doubt be found to be so, were 
the Cynipidew more studied by British entomologists. Dr. 
Mayr’s description and figures of the gall will no doubt 
appear in a later number of the ‘ Entomologist.’ I hope the 
reproduction of the excellent figures in his work will call 
entomologist’s attention to the study of British galls, their 
makers, and parasites—Hdward A. Fitch; Down Hall,

Correction of an E'rror.—May I ask you to state that all 
the Aphides marked “females” in my list of desiderata, 
inserted in your May number, are required to be “ winged 
females,” except Schizoneura vagans, unless they should be 
oviparous females. Your readers are doubtless aware that 
Aphides occur under five forms, namely, as larve, pupe, 
winged females, winged males, and wingless oviparous 
females. The three first are oviparous, and have incomplete 
sexual characters; the two last are to be regarded as the 
mature individuals of the series —G. B. Bucklon; Wey- 
combe, Haslemere, May 5, 1874.

Economy of Bees and Wasps.—Sir John Lubbock read 
some “ Observations on Bees and Wasps.” The paper com- 
menced by pointing out, with reference to the power of 
communication with one another, said to be possessed by 
Hymenoptera, that the observations on record scarcely justify 
the conclusions which have been drawn from them. In 
support of the opinion that ants, bees, and wasps, possess a 
true language, it is usually stated that if one bee discovers a 
store of honey, the others are soon aware of the fact. This, 
however, does not necessarily imply the possession of any 
power of describing localities, or anything which could 
correctly be called a language. If the bees or wasps merely 
follow their fortunate companions, the matter is simple
