Mr. W. E. Nicholson exhibited several specimens of Act- 
dalia immorata, Linn., caught by him near Lewes. Mr. 
Jenner Weir remarked that the species had only recently 
been added to the British list, and that it was remarkable how 
so comparatively large a species could have been hitherto 
overlooked. It was also remarked that a specimen of this 
species from the collection of the late Mr. Desvignes had 
been exhibited by Mr. Stevens at the meeting of the Society 
in November, 1887. 
Dr. Sharp exhibited a large number of species of Rhyncho- 
phora, collected by Mr. George Lewis in Japan. 
Papers read. 
Mr. F. P. Pascoe read a paper entitled ‘‘ Descriptions 
of new Longicorn Coleoptera.”’ 
Dr. Sharp read a paper entitled ‘‘The Rhynchophorous 
Coleoptera of Japan.’ The author said that the Rhyncho- 
phora brought by Mr. George Lewis from Japan, fifteen years 
ago, were examined by M. Roelofs, and described by him in 
some papers that appeared in the ‘ Annales de la Societé 
Entomologique de Belgique,’ 1874 and 1880. Since then 
Mr. Lewis had obtained a much more extensive collection, 
and as M. Roelofs was no longer occupied with entomology, 
he had undertaken the task of revising the collection by the 
assistance of this much richer material; and he now dealt with 
the first two families, Attelabide and Rhynchitide. Dr. Sharp 
remarked that he was surprised to find, on examining the first 
of these groups that they formed an exception to the other 
Rhynchophora in the structure of the prosternum. Leconte 
recently drew attention to the importance of this part of the 
body as a means of separating the Rhynchophora from other 
Coleoptera; and it was very curious that he should not have 
noticed that this family, which he correctly placed at the 
commencement of the series, differed from his definition of 
Rhynchophora in this important particular. In order to define 
the structure of the prosternum in these insects, Dr. Sharp 
said he had been obliged to make use of a new term, which 
he would explain.
