194 THE ZOOLOGIST. 
Mr. G. H. Verrall alluded to the probable use that might be made 
of micro-photography in illustrating the neuration of transparent winged 
insects; and exhibited many prints and negatives illustrating the wings of 
Scatopse, Tipula, and other Diptera. 
Mr. T. R. Billups exhibited specimens of Ceraleptus lividus, Stein., 
captured at Chobham on the 28rd February last. 
Rev. W. W. Fowler exhibited the unique specimen of Cerylon atratulum 
from Hungary, which had been lent to him by Herr Reitter ; also specimens 
of an Indian Cassida, which had been soaked in a preparation to preserve 
their brightness of colour. 
Dr. Sharp said the last exhibit raised the curious question, On what 
does the colouring matter of the Cassida depend? The application of 
glycerine under the wing-cases of certain Coleoptera maintained the bright 
colour for a short time, and moisture probably had something to do with 
colour, as he had often revived lost colours by soaking specimens in water 
for a day or two. 
Mr. Fowler also exhibited a microscopic movable stage of ingenious 
construction and efficient application, made by Messrs. Smith and Beck. 
Mr. W. F. Kirby exhibited, on behalf of Mr. Waterhouse, a beautiful 
variety of Spilosoma lubricipeda, Esp., recently captured by a policeman in 
the British Museum (Natural History), South Kensington.

Observations touching Mr. De Nicéville’s recent Suggestions on Seasonal

Braconide.” 
Rev. W. W. Fowler read “‘ Descriptions of new species of Languriide.” 
Mr, R. M‘Lachlan read a note “ On the discovery of a species of the

on January 3rd last. 
Mr. E. A. Fitch exhibited a large moth, belonging to Mr. W. H. 
Harwood, which was captured by Dr. Wallace on the wall of his garden at 
Colchester, in October, 1883. It apparently was one of the Chilonide, and
