Mr. Janson mentioned Tomicus villosus as a nearly parallel case among the 
Coleoptera; it was true Ratzeburg figured an insect which was said to be the male, 
but, though myriads of the female were found annually, he believed that the male had 
never been detected in this country. 
The President exhibited a specimen of one of the wingless Diptera which he had 
found at Farnborough, Kent, under bark, in company with Thysanura. He believed 
it to be the Epidapus venaticus of Haliday (see Walker, Ins. Brit. Diptera, iii. 56). 
Mr. 8. Stevens exhibited specimens of Gordius aquaticus [but see below], numbers 
of which were that morning observed on the ground in his garden at Kennington after 
the heavy rain of the previous night. A nephew of his had also seen the Gordius at 
Ashford on rose-trees. Mr. Weir had noticed them at Brixton, and Mr. Bond near 
the Regent’s Park, on bushes. 
Prof. Westwood enquired whether any Member present had noticed any constant 
variation in colour, or markings, or other external character, by which the sex of larve 
could be determined? Mr. F, Smith said that he had once found a lot of Anuthophora 
larve, which, instead of the usual ivory-white, were of a saffron-yellow colour; but 
they produced male and female Anthophore indiscriminately. Mr. Stainton remarked 
that larve of Cherocampa Elpenor and Porcellus occurred of two different colours, but 
he could not say whether the differences were sexual. Mr. Bond, however, had kept 
the two forms of C. Elpenor separate, and each form had produced both sexes.

Exhibitions, &c. 
Mr. Busk (who was present as a visitor) mentioned, on the authority of Dr. Cob- 
bold, that the small worm exhibited at the previous Meeting was not Gordius 
aquaticus, but Mermis nigrescens. 
Mr. M‘Lachlan exhibited Ciniflo ferox from Folkestone, where that spider had 
been captured by Dr. Knaggs; and living specimens of a spider and a large centipede, 
which were found in the hold of a ship recently arrived from Manilla with a mixed 
cargo, principally consisting of sugar and hemp. 
The Secretary exhibited branches and the fruit of an orange-tree infested with 
some insect, with regatd to which information was requested by Mr, Charles Moore,
