to us. I must own to a measure of scepticism as to some of 
the particulars related, a scepticism heightened by the fact 
that I had tried the experiment in vain with a female 
B. Quercus, in a spot which the species frequented. The 
emergence of three females, last July, gave me a new oppor- 
tunity of testing the attractive power which resides in them, 
though I had to keep them prisoners for some days ere I could 
take them to a suitable locality. This I was able to do on 
August Ist, and had sufficient evidence that the very rapid 
discursive flight of the male Quercus can be brought to 
a check by the presence of the female. Several eagerly 
surrounded the bag in which these females were enclosed, 
almost regardless, for the moment, of the danger to them- 
selves, while others flew round in circles. It was observable, 
however, that when struck at, if they escaped, they usually 
took alarm and flew off. Now and then one would sweep up, 
and, perceiving the position in which the objects were which 
had attracted him, departed at once, without endeavouring to 
come any closer to the box containing the prisoners. Appa- 
rently, the presence of the male insect is also, in some 
manner, indicated to the female, for those that were taken 
out for this experiment, though before that they were 
quiescent in the day-time, were in a state of agitation, even 
when the box in which they were enclosed was kept quite 
still. After 2 p.m. the males, from some cause, ceased to 
take any notice of the females, though they had not ceased 
to fly about. The female of Quercus, when impregnated, 
deposits her eggs with great rapidity, a hundred or more 
being got rid of in an hour. The whole number are not got 
rid of in confinement, the stimulus of flight being necessary 
to remove the whole from the ovary.—J. R. S. Clifford. 
P. Daplidice and A. Lathonia in Jersey.—These rare 
insects have been tolerably abundant here this season. The 
former (of which I have taken thirteen) are only found in one 
locality, and have been established there these last two 
years, before which time they were seldom seen in the 
island. The latter has been taken in several localities, also 
rather abundantly, having taken sixteen myself, and I know of 
other collectors equally successful: this, also, is seldom 
seen.—J. Piquet ; 12, York Street, Jersey, October 5, 1871.
