Of this variety Mr. Eaton nfebtainea one example near Lisbon, another 
at Croydon in a hothouse, and a third on the Isle of Purbeck, in Dorsetshire. 
In the other variety the predominant colour is either brownish ochre or 
dull pale greenish yellow-ochre ; the antenne, head, and a transverse dorsal 
band at the base of each of the body segments, not extending into the epimera 
and mostly interrupted in the middle, blackened; in one example some 
of the anal segments are marked with a pair of dorsal blackened spots, 
and in two examples the ultimate pair of legs are blackened. Three 
specimens of this variety were found beneath a stone, with one example 
of the typical form, close to the sea-shore near Osmington Mill, in 
Dorsetshire. 
In the new colour-variety of Porcellio scaber the whole animal is of a 
dull reddish rusty yellow (rufescente rubiyinosa) on the back, and whitish 
beneath. The epimera in one example are paler than the body. During 
life the dark contents of the digestive tube are visible from above, and the 
pale marbling of the integument is inconspicuous; but when dried the former 
disappears, and the latter (under a lens) becomes plainly distinguishable. 
Two examples of this variety were captured on the Dorsetshire coast between 
West Lulworth and Osmington Mill. 
The Icelandic specimen of Porcellio scaber was obtained by Mr. J. Coles, 
near Reykjavik, on September 10th last, at an altitude of about 40 ft. In 
Portugal this is a common species, from the seashore in the province of 
Minho to over 8000 ft. in the kingdom of Algarve, and to upwards of 
4000 ft. in the province of Traz-os-Montes. It has an extensive distribution 
in other parts of Europe, and is quoted as an introduced species in North 
America. 
Dr. H. C. Lang exhibited a specimen of Lycwna Icarus, Rott. (Alexis, 
W. V.), var. [carinus, Scriba, in which the basal spots on the under side of 
the fore wings are absent. Dr. Lang thought it would be difficult to 
distinguish the female of this variety from L. Medon, Esp. 
Mr. J. Jenner Weir remarked that he possessed specimens of this 
variety, but he believed it to be of very rare occurrence in Britain. 
Mr. W. L. Distant exhibited a specimen of an undescribed species of 
Cicadida from Borneo, in which the opercula were developed to a greater 
extent than in any other species with which he was acquainted, being not 
only longer than the abdomen, but also extending beyond the lateral 
margins of the same. Mr. Distant did not, however, wish to be understood 
as implying that this insect, from the great size of the opercula, must 
necessarily be remarkable for the depth and intensity of the sound it 
produced over other Bornean species. In America Cicada opercularis, 
having the opercula well developed, was one of the shrillest and loudest 
musicians, but in the same region was found T'ympanoterpes gigas, whose 
noise had been described as equalling the “ whistle of a locomotive,” but in
