expressed his willingness to indicate the exact spot to any 
Fellow of the Society visiting Weymouth during the coming 
summer, but he preferred not to publish it for obvious reasons. 
From the same town a specimen of L. adonis, 2, with similar 
variation, was also exhibited. Professor S. H. Scudder, of 
Cambridge, Mass., U.S.A., stated that he had observed the 
occurrence of broods with suffused spots in America, but they 
were not confined to any special locality. 
_ Mr. C. O. Waterhouse exhibited the type-specimen of 
Coptomia opalina of Gory, from the Hopeian Collection at 
Oxford, and pointed out that it was quite distinct from C. 
mutabilis, W. The distinct punctuation of the whole insect, 
and the striolate pygidium in C. opalina, were sufficient to 
distinguish it at once. Mr. Waterhouse called attention to 
this, as some French entomologists maintain that these 
insects are the same species. He also called attention to 
Silpha atomaria, of Linneeus (Syst. Nat., ed. xii.,i., p. 574), a 
Swedish species which appeared to have escaped notice, and 
was not included in any catalogue. The type is still extant 
in the Linnean cabinet, and Mr. Waterhouse said he was of 
opinion that it is Olibrus geminus of our collections, but 
he had not had an opportunity of making a critical exami- 
nation. He also exhibited male and female specimens of a 
Helopeltis (the Tea-Bug), which he considered a distinct 
species, and stated that it had occurred only in Assam. 
Mr. M. Jacoby exhibited certain species and varieties of 
the genus Ceroglossus from Chili, and Dr. D. Sharp, Mr. J. J. 
Walker, R.N., and Mr. Champion made remarks on their 
geographical distribution. 
Prof. Scudder exhibited the type-specimen of a fossil 
butterfly—Prodryas persephone—found in beds of Tertiary Age 
(Oligocene) at Florissant, Colorado. He said the species 
belonged to the Nymphalidae, and the specimen was remark- 
able as being in more perfect condition than any fossil 
butterfly from the Kuropean Tertiaries. He also stated that 
he had found a bed near the White River on the borders of 
Utah, in which insects were even more abundant than in the 
Florissant beds. Dr. Sharp, Mr. Kirby, Mr. H. Goss, and 
the President took part in the discussion which ensued.
