the eggs developed in the ovaries. He also mentioned that Gra- 
jihiphora suhrosea had been recently captured at Whittlesea Mere, 
thus proving it to be indigenous ; which was the more interesting, 
as it agrees in the structure of the antennae with a North American 
group of which there is no other European representative. Deiopeia 
pulchella had also been captured at Epping at the end of September. 
He also stated that the larva of Folia occulta feeds upon species of 
Polygonum, and not on the dandelion as represented by some authors. 
Mr. Hope stated that two specimens of Catocala Fraxini had been 
taken at Southend. 
The following papers w'ere read : — 
Extracts from a letter addressed to Mr. Westwood by Captain 
Hutton, containing a series of observations on the Indian species of 
Papilio. 
Extracts from a letter addressed to Mr. Westwood by R. Tem- 
pleton, Esq., containing notices of some of the Lepidoptera of Ceylon. 
The completion of Mr. Savage’s memoir on the driver ants was 
also read. 
Mr. E. Doubleday, in allusion to the two former communications, 
stated his belief that Papilio Panope and similis are the sexes of one 
species ; also that P. Pammon and Polytcs are varieties of one 
species, as affirmed by Boisduval ; and that the insects regarded as 
the two species, P. Epius and Demoleus, by Captain Hutton, were 
the sexes of one species (as indeed Mr. Templeton had stated in his 
letter) . 
November 2nd. — The Rev. F. W. Hope, F.R.S., President, in the 
Chair. 
Mr. Newport exhibited a box of Coleoptera, &c. from Melbourne, 
South Australia, including a large new' species of Eucranium }, Ce- 
rapterus Plopii, Slc. ; and also a s]>ecies of Blatta of which the left 
hind leg had evidently been reproduced, being smaller than the other. 
Instances of the reproduction of the antennee, but not of the feet, 
had hitherto been noticed in this group. 
Mr. Griffith stated that he had observed during the preceding 
autumn, on one small spot of w'oody ground at Addington Hiil near 
Croydon, a very great number of specimens of Cynthia Cardia. 
Captain Frend stated that he had found Vanessa Urticcc alone in 
some quantity on the summit of the Sierra Nevada in Spain, 16,000 
feet above the level of the sea. 
Mr. Weaver exhibited a new' British Noctua allied to Hadena 
adusta, and other rare Lepidoptera from Perthshire. 
Mr. F. Bond exhibited a living specimen of Sphinx Atropos, and 
stated that he was convinced that the cry emitted by this insect was 
not produced by the moveable appendages at the sides of the thorax, 
as he had found that the noise was equally strong wffien the sides of 
the thorax were violently compressed and held tight. Mr. Newport, 
who had also examined the insect wdiilst alive, stated that in his 
opinion the noise was either produced by the lateral friction of the 
parts of the spiral tongue (maxilltc) against each other, or by their
