Entomological Society ok Londox. 6th May, 1867. — Professor Westwood, 
M.A., F.L.S., Vice-President, in the Chair. 
J. Sidebotham, Esq., of George Street, Manchester, was elected an Ordinary 
Member, and Herr Snellen Van Vollenhoven, of Leyden, was elected a Corresponding 
Member. 
Mr. Stainton exhibited cases of Coleophora lixella, and made some remarks on 
the habit of the insect; from which it appeared that the young larva, when first 
hatched, feeds upon Thymus serpijllum, and uses a seed-calyx of that plant for its 
case : afterwards it forsakes the thyme and wanders on to grass, leaves its first 
case attached to a blade, and proceeds to form its ordinary adult case out of the 
grass leaf. The discovery of this extraordinary habit is due to Herr Von Heine- 
mann, of Brunswick. He also exhibited a larva of Hyponomeuta egregiella on Erica 
cinerea from Fontaineblean. 
Prof. Westwood remarked on an Hemipterous insect from New Sonth Wales, 
belonging to the Reduviidce, which had a habit of dancing high in the air, after the 
manner of gnats, and possessed a powerful odour of musk, so as to strongly scent 
the letter in which it was sent. 
Mr. Fereday communicated a photograph of an example of Pyrameis cardui 
from New Zealand, being the first obtained in those islands : it pertained to the 
race found in New Holland. 
Mr. C. A. Wilson communicated an example and notes on a species of Xenos 
{Stylopid(c) found in Australia, parasitic upon Paragra decipiens ; this was ajDparently 
the first instance of these insects being found in that quarter, and was a discovery 
of Madam Kreusler, of Gawler. Mr. Smith exhibited some of the infested wasps. 
Mr. Stainton remarked that a large dipterous larva had emerged from a 
bug (Pentatoma) found by him at Mentone. 
Mr. Bates read a communication from Dr. Felder, of Vienna, who is engaged 
on the Lepidoptera of the Novara-voyage, respecting the method of publication of 
that work, involving a question of priority. 
Mr. Bates also read descriptions of new species of Butterflies collected by Mr. 
Belt, in Maranham. 
NEW GENERA OF LONGICOBN COLEOPTERA FROM THE RIVER 
AMAZONS. 
BT H. W. BATES, T Z.S. 
The followiug descriptions of new genera are published in deference 
to the wish of M. Lacoebaibe, Avho is now preparing the " Lonfficornes'' 
portion of his masterly work, " G-enres des Coleopth'es,'^ and considers 
it desirable that all who are engaged in writing on the group, should 
make known the genera in time to be included in his volumes. The 
description of all the species of Longicorns taken by me on the 
Amazons, one part of which (the Lamiadcs) has already appeared, will 
shortly be continued. The present genera all belong to the GeramhycideB 
section, the species of Prionidce and Lepturidcn of the Amazons falling 
into genera already established.
