JOURNAL OF PROCEEDINGS. 
Exhibitions, Memoirs, &c. 
Mr. Shipster exhibited a large collection of Coleopterous insects 
obtained by him from the rough turpentine. 
Mr. Hope exhibited a selection from a collection of insects 
made by E. T. Downes, Esq., Assistant Surgeon at Neemuck in 
the East Indies, including a new Paussideous insect ( Platyrho - 
palus angustus, Westw.), a Dipterous insect closely allied to 
Spliryrocepliala (Say), a large species of Cermatia , a Solpuga, a 
Pimelia, a very large Onitis, Oiceoptoma tetraspilota, &c. Al- 
luding to the last-mentioned insect, Mr. Hope opposed the opinion 
that Necrophagous insects were of great rarity in India, believing 
their apparent rarity to have originated in the prejudices enter- 
tained by the native castes against touching dead bodies. He 
moreover considered, from the exhibition now made, that there 
must be a considerable agreement between tropical Asia and 
Africa. 
The Rev. L. Jenyns exhibited an apod larva, of which three 
individuals had been found during the preceding summer in the 
key-hole of a writing-desk, embedded in a mass of clay, without 
any food having been apparently laid up in store. 
The completion of Mr. Newport’s Memoir on the Use of the 
Antennas was read; in support of the observations in which, Mr. 
Hope entered into various remarks upon the different senses, con- 
sidering that there was an intimate connexion between sight and 
hearing (the one being requisite to obtain clear perceptions of the 
objects causing impressions upon the organs of the other sense), 
and which seemed to be proved, amongst the Longicorn beetles, 
by the antennae being inserted in a deep notch of the eye. He 
was hence induced to consider that the sense of hearing existed in 
insects either in the terminal or basal joint of the antennae. The 
ordinarily minute size of the second joint seemed to him as likely 
to have for its object the condensing of the sound carried along 
the nerves of the elongated terminal joints, and which afterwards 
diverged in the large basal joint. 
Mr. Newport stated that he had recently, at the request of 
Mr. Hope, made some anatomical observations upon the internal 
parts of the head in the region of the base of the antennae, and 
that he had discovered the two membranes of which Treviranus 
had spoken. At the base of the antennae in Blatla he had disco- 
vered a free space, inclosing a membrane over which passed a 
branch of the nerve from the base of the antennary nerve, without 
the intervention of a sac.
