440 THE ZOOLOGIST. 
Mr. Rutherford exhibited, and communicated a description of, a new 
species of Goliath beetle, from Mount Camaroons, allied to Ceratorrhina 
Sayi, Westw. He also exhibited a specimen of a West African butterfly, 
Romaleosoma Ruspina, Hew., nearly a third of the wings of which, on both 
surfaces, along their outer margin, and beginning a little below the apical 
angle of the primaries, were entirely destitute of scales, with the exception 
of the nervures, which were sparsely covered with them. The symmetry of 
the transparent portion of the naked wings seemed, he thought, to preclude 
the idea that the butterfly had been partly denuded of its scales, either 
intentionally or by accident; and he inclined to the conclusion that the 
appearance it presented was due to some abnormal physiological condition 
occurring either in the larva or chrysalis. 
Mr. G.C. Champion exhibited specimens-of Amara infima, from Chobham, 
Surrey, this rare insect not having been recorded since 1857, when Dawson 
first added it to the list of British Coleoptera. 
Mr. W. A. Forbes exhibited a collection of insects from Switzerland, 
taken at the latter end of June in a valley in the neighbourhood of 
Chamouni, at an elevation of 5000 or 6000 feet. 
Mr. J. Wood-Mason read a note “ On a Saltatorial Mantis,” and exhibited 
a specimen of the insect, which had been captured on the banks of the 
Tagus. He also read notes “ On the hatching period of Mantid@ in Eastern 
Bengal,” and “On the presence of Stridulating Apparatus in certain 
Mantide,” this being the first discovery of such an organ in that family. 
The author exhibited, in illustration of the last note, a large Mantis, showing 
the serrated fore margin of the tegmina by means of Which the stridulation 
is effected. 
Mr. Wood-Mason also stated that it might interest the members of the 
Society to hear that in the course of his anatomical work he had discovered 
a remarkable case of viviparity in the Orthoptera, in a large cockroach 
belonging to the genus Panesthia, the species of which inhabited the 
tropical forests of Southern Asia and of Australia, where they lived in 
the rotten wood of fallen trees. The species in question was P. Javanica, 
from the abdominal brood-pouch of the female of which he had extracted 
young white specimens of 6-5 mm. in length, and these, from their being 
already provided with legs, antenne, black eyes, and the full number of already 
hard-tipped gnathites, as well as from their size, he judged were just on the 
point of birth when the mother was thrown into the alcohol. He further 
suggested that the curious and as yet unexplained habit evinced by several 
European species of Blattide of carrying their egg-capsules about with 
them for a week, or even for so long a period as a fortnight, before depositing 
them, might possibly be explicable as the retention of a vestige of a lost 
viviparousness.—R. Mrxpoxa, Hon. Sec.
