SCIENTIFIC SOCIETIES. 239 
A communication was read from Col. C. Swinhoe, containing descriptions 
of seventy-five new species of Indian Lepidoptera, chiefly Heterocera. 
A communication was read from Rev. O. P. Cambridge, containing the 
description of a new Tree Trap-door Spider from Brazil, proposed to be 
called Dendricon rostratrum. 
Mr. F. E. Beddard read some notes on the anatomy of an American 
Tapir, Tapirus terrestris, based on a specimen lately living in the Society’s 
collection. 
A communication was read from Prof. Bardeleben, of Jena, on the 
prepollex and prehallux of the Mammalian skeleton. The author recorded 
the presence of a two-segmented nail-clad preepollex in Pedetes, and that of 
a two-segmented pisiform (post-minimus) prehallux in Bathyergus. He also 
stated that he had discovered vestiges of the prehallux and prepollex in 
certain Reptilia. He then passed to the consideration of the Mesozoic 
Theriodesmus of Seeley, and denied the existence of the scapho-lunare of 
that author, while he produced good reason for believing the same observer's 
second centrale to consist of two elements, and his przaxial centrale to be 
the basal element of a prehallux. 
Mr. Oldfield Thomas read the description of a new genus and species 
of Muride from Queensland, allied to Hydromys, which he proposed to 
call Xeromys myoides.—P. L. ScuaTER, Secretary. 
Entomotoaicat Society or Lonpon. 
May 1, 1889.— Mr. Freprricg Du Cane Gopman, M.A.,, F.B.S., 
Vice-President, in the chair. 
Mr. Walter F. H. Blandford, B.A., and Mr. John W. Downing, were 
elected Fellows; and Dr. Neville Manders and Mr. Arthur Cant were 
admitted into the Society. 
Mr. W. L. Distant announced the death of Dr. Signoret of Paris, one 
of the Honorary Fellows of the Society. 
Dr. Sharp exhibited male and female specimens of an abnormal form 
of Rhomborhina japonica, found in Japan by Mr.G. Lewis. ‘They exhibited 
a contraction of the thorax, which was much narrower than usual at the 
base, so that the mesothoracic epimera were entirely exposed. Dr. Sharp 
also exhibited a small collection of Coleoptera made by Dr. N. Manders 
in the Shan states, Upper Burmah; this collection contained several new 
interesting forms, the most remarkable being a small Heteromerous insect 
bearing a considerable resemblance to Rhysodes. Amongst the specimens 
was an example of Batocera roylei, which he had retained in a relaxed 
condition, so that the Fellows might have an opportunity of hearing its 
stridulation; this was produced in a very audible manner by the base of
