PROCEEDINGS OF SCIENTIFIC SOCIETIES. 39 
Mr. C. O. Waterhouse read a paper containing “ Descriptions of new 
Species of the Coleopterous Genus Callirhipis (Rhipidocerida) in the British 
Museum,” and exhibited specimens of C. longicornis, male, Waterh. (Anda- 
man Islands), and C. dissimilis, male and female, Waterh. (Borneo). 
The Rev. H. S. Gorham communicated the continuation of his 
“Descriptions of New Species of Cleride, with Notes on the Genera and 
corrections of Synonymy.” 
Mr. A. G. Butler communicated a paper containing “ Descriptions of a 
New Genus and two New Species of Sphingida, with general Remarks on 
the Family.” 
Mr. J. S. Baly communicated ‘Descriptions of New Genera and of 
uncharacterized Species of Halticine.” 
December 5, 1877.—J. W. Dunning, M.A., F.L.S., Vice-President, in 
the chair. : 
Donations to the Library were announced, and thanks voted to the 
donors. 
Mr. W. L. Distant exhibited two rare species of Hemiptera-Heteroptera 
from the West Coast of Africa, viz. Tetroxia Beauvoisit, Fairmaire, and 
Oncocephalus subspinosus, A. & 8. 
Mr. F. Smith exhibited a fine series of both sexes of Macropis labiata, 
captured by Mr. J. B. Bridgman, of Norwich, at Brundall, near that city. 
A British specimen of the male had for many years been unique in the 
collection of the British Museum; at length a second male was taken in 
the New Forest by the late Mr. J. Walton, and twenty years subsequently 
Mr. S. Stevens took a third at Weybridge. During the past season 
Mr. Bridgman took both sexes in some numbers. 
Mr. Smith also exhibited a specimen of Rophites quinquespinosus, captured 
at Guestling, near Hastings, by the Rev. KE. H. Bloomfield during the past 
season. This capture added a genus and species to the British Hymen- 
opterous fauna, and was the most important addition that had been made 
for many years. 
Mr. Meldola exhibited three photographic enlargements of micro-photo- 
graphs by Mr. Edward Viles, of Pendryl Hall, Wolverhampton. These 
photographs, two of which were of parts of insects,—viz. the mouth organs 
of a bee and the proboscis of a fly,—had been exhibited at the recent 
Exhibition of the Photographic Society of London, and had obtained one of 
the Society's medals. The original negatives, taken by means of the 
object-glass of a microscope fitted into the camera in place of the ordinary 
lens, were 3 inches square, while the finished enlargements were 30 x 24 
inches, being thus enlarged 10 diameters. 
Mr. Meldola next exhibited an acoustical experiment illustrating the 
effects of resonance in increasing the volume of sound emitted by
