\ 20 rOolober, 18G6. 
Mr. JanBon exhibited a box of Coleoptera collected by Mr. Gloyae in the 
neighbourhood of George Town, Jamaica. 
Mr. Bond exhibited a series of the Ailanthus silkworm moth, bred by Dr. 
Wallace, varying greatly in size, the largest measuring 6^ inches in expanse, and 
the smallest not more than 3 inches. The Secretary stated that Dr. Wallace would 
be happy to show his Ailanthus plantations at Colchester to any Member, provided 
he received a day's notice. 
Professor Westwood said that he had found wasps very destructive to the young 
larva9 of the new silkworm. 
Mr. S. J. Wilkinson read an extract from the Report of Mr. Consul Lay, at 
Chefoo (received from Prof. Brayley) respecting the quantity of "brown silk" 
grown annually in that province. It was not stated what species produced this silk. 
Mr. S. Stevens exhibited a house-fly to which no less than six CJielifers had 
attached themselves. 
Mr. E. S. Haines sent for exhibition a curious variety of Cidaria fluctitata, 
resembling the 0. costovata of Haworth. 
Mr. Stainton exhibited a series of Micro-Lepidopiera received from M. Milliere, 
of Lyons, amongst which were the Depressaria rutana of Fabr., bred from Ruta 
angustifolia, and a new Gelechia, resembling 0. costella, bred from Hyoscyamus albus. 
Mr. Pasooe read a description of Anastetha raripila, a new genus and species 
of Tmesisterninx, recently received from Queensland. He mentioned, with respect 
to the presumed Australian origin of the fauna of New Guinea according to the 
views of Mr. Wallace, that the Coleoptera of the two countries did not appear to 
confirm this origin ; for instance, a hundred species of Tmesisterninas had been 
found in New Guinea, whereas, only three were known from Australia ; others had 
been found in New Caledonia, presenting certain peculiarities inter se. 
Mr. Trimen communicated a paper on the Rhopalocera of the Island of Mauri- 
tius. He enumerated twenty-five species. He considered that this portion of the 
Mauritian fauna was decidedly of African origin, most of the species being identical 
with those found in South Africa and Madagascar. 
Mr. Wilson communicated some further notes on South Australian BwprestidoB. 
Mr. Schrader, of Shanghae, sent drawings and description of the metamor- 
phoses of a species of Qeometridce found upon the willow in the neighbourhood of 
Shanghae. Mr. Moore recognised it as a species of Agathia. 
Mr. Smith read a paper on certain Hymenoptera from Catagallo, South America, 
sent to him by Mr. Peckolt. The most interesting amongst these was the female 
of Trigona, a genus of which the males had only previously been noticed. These 
females had enormously developed abdomens when in a gravid condition, 
and in this respect resembled the same sex of Termes. There was also an ant 
parasitic in the nests of Trigona. 
Mr. McLachlan remarked, that the new genus of exotic Trichoptera, described 
by him in the last part of the Transactions under the name of Sciops, is identical 
with Hydromanicus of Brauer, published in the last vol. of the Verhandlungen der 
Zool. bot. Gesellschaft in Wicn. The latter name has priority. 
The next Meeting of the Society will be held in the Linnean Society's Eooms 
at Burhngton House on the 5th of November.
