island. Nearly all the insects were remarkable for being either apterous or 
with greatly abbreviated wings. There were two Lepidoptera, one (only a 
larva) probably belonging to the Noctuina, the other to the Tineina. Of 
the Diptera, one species had neither wings nor halteres; another lived 
habitually on rocks covered by the tide at high water, and its larva fed upon 
a species of sea-weed. All the larger Coleoptera seemed to have their elytra 
soldered together. Mr. M‘Lachlan said that the theory as to the apterous 
condition of the insects was, that the general high winds prevailing in those 
regions rendered the development of wings useless; and Mr. Jenner Weir 
remarked that the apterous condition was correlated with the fact that plants 
under similar circumstances were apetalous and self-fertilising ; and hence it 
was supposed that the existence of winged insects was unnecessary. 
Mr. C. O. Waterhouse exhibited a Chekanops, of which he had discovered 
two specimens under the elytra of Passalus punctiger, from Rio Janeiro, 
thus confirming the statement that these insects attach themselves to the 
bodies of other insects after the manner of Acari. 
Mr. C. O. Waterhouse also exhibited a drawing of a Neuropterous insect 
of the family Ascalaphide, from Swan River, presenting the peculiarity of 
having a large bifid hump on the basal segment of the abdomen dorsally, 
each division of the hump bearing a crest of hairs. He believed it to be 
the male of Suphalasca magna, M‘Lachlan. 
Mr. Wormald exhibited a collection of Neuroptera, &c., from the neigh- 
bourhood of Yokohama, received from Mr. H. Pryer. It included several 
interesting species of Panorpide, including a new genus of that family, 
according to Mr. M‘Lachlan; fine species of Osmylide, &c. Amongst the 
Trichoptera was a remarkable species of the genus Perissoneura, black with 
a large white spot in each wing, deceptively resembling a butterfly, especially 
an Ithomia. 
A note was received from Mr. Albert Miller, stating that the galls taken 
by Mr. W. Cole on ash-leaves at West Wickham, as stated in the ‘ Pro- 
ceedings’ of this Society for 1874 (p. xix.), were produced by Cecidomyia 
botularia, Winnertz, and that a life-history of the fly was given by him in 
the ‘Gardener's Chronicle,’ 1870 (p. 1731), and reprinted in ‘ Newman's 
Entomologist’ (v., pp. 248—250). 
Professor Westwood communicated “ Descriptions of some New Species of 
Short-tongued Bees belonging to the genus Nomia, Latreille”; and also a 
paper “ On the Species of Rutelide inhabiting Eastern Asia and the Islands 
of the Eastern Archipelago.” 
Mr. C. O. Waterhouse communicated a description of a new species 
belonging to the Lucanidee (Prosopocelus Wimberleyi), by Major F. J. 
Sidney Parry; and also a description of the male of Alcimus dilatatus, by 
himself..— F’. G.
