Mr. Westwood, in reference to some observations made by 
Mr. Newport on the excitement previous to impregnation of a 
species of Pleromalus by the contact of the antennae of the oppo- 
site sexes, stated that he had observed the latter operation in 
other species of that family, and that the act of impregnation itself 
occurred in the ordinary manner, the vagina of the female being 
situated near the base of the abdomen beneath. He likewise con- 
sidered that the proceedings of the house-fly, so often observed in 
autumn, did not constitute copulation, but were merely acts of 
excitement.

Mr. Raddon exhibited a portion of gum containing insects 
which he considered to be gum Copal, and another portion with- 
out insects which he named Anime ; and made some observations 
on the distinction between these two substances. Mr. Hope, 
however, considered that both portions of gum were Anime, re- 
taining his opinion that the Copal never contained insects. There 
was great difficulty in tracing the original country of these gums, 
the dealers mixing them promiscuously, but he believed that the 
gum produced in the Old World was insectiferous, whilst that 
exuding from trees in the New World was not. There was also 
great difference between the same gum at different times, that 
which was a year old being much paler than that which was four 
years old.
