insects. Hemerohius nervosus, one ^ , bred from an old gall of Ct/nqjs Kollari; sub- 

 nebulosus, very common, frequenting gardens, and coming to light ; limlatus, 

 common ; humuli, very common, especially in woods ; mieans, not common ; niti- 

 dulus, not common ; pellucidus, one specimen ; elegans, not common. Micromus 

 paganus, common ; aphidivorus, five specimens ; variegatus, rather common. Sisyra 

 terminalis, not common ; fuscata, rather common. RapMdia xanthostigma, one 

 specimen. Sialis fuliginosa, rather common ; lutaria, very common. 



In Chrifsopa the upper basal portion of the third cubital cellule is separated 

 off from the rest of the cellule by a partition veinlet, and forms an elongate gem- 

 miform cellule ; in two specimens of C. alba this gemmiform cellule is reduced to 

 about half its usual size, and ends at or about the insertion of the ti'ansverse veinlet 

 above it. In one specimen of C. phyllochroma the third cubital cellule is divided 

 nearly in half, thus rather simulating Nothochrysa. The reddish line on the side of 

 the face in C.flavifrons is very unstable, being sometimes broken up into three 

 elongate spots, at others into dust-like punctures below a small fuscous dot, and in 

 one instance is replaced by a distinctly black roundish spot. — J. E. Fletchee,

Entomological Society of London. — March Uh, 1885 : E. McLachlan, 

 Esq., F.R.S., President, in the Chair. 



Messrs. R. W. Lloyd, of 32, Grafton Square, W. E. Poole, of 11, Chandos 

 Street, A. Bliss, of Pendennis, Allenby Road, Forest Hill, and R. South, of Abbey 

 Gardens, St. John's Wood, were elected Members. 



The President alluded to the news of the decease of three Members since the 

 last Meeting, viz. : — Major Parry, Mr. E. C. Rye, and the Rev. D. J. French. 



Mr. Yerrall exhibited prints and negatives of micro-photographic representa- 

 tions of the wings, and other parts, of native Diptera. He found an exposure 

 of ten minutes by gas-light to answer more certainly, and with less chance of error, 

 than a second or two by sunlight. The plan seemed admirably adapted for truthful 

 reproduction of the neuration in transparent-winged insects. Mr. Meldola said the 

 photographs could be utilized for scientific purposes by the photo-zincograph, and 

 other analogous processes. 



Mr. Billups exhibited Ceraleptus lividus, a rare British bug, from Chobham j 

 it had previously only been recorded from Deal and Camber. 



The Rev. W. W. Fowler exhibited the unique example of Cerylon atratulus, 

 lent to him by Herr Reitter : also specimens of an exotic Cassida prepared by a 

 taxidermist at Lincoln, in which the colours were well preserved. Dr. Sharp re- 

 marked that the late Mr. Rye used to bring out the colours of Cassididce by forcing 

 glycerine under the elytra ; he was of opinion that the colour existed in the elytra, 

 and not in the body, and was to a large extent due to the natural moisture, the 

 colours disappearing when the insects became dry. Mr. Fowler exhibited one of 

 R. and J. Becks' opaque disc revolvers for the microscope, which they had mounted 

 for him on a universal hinge, so that change of position in every conceivable direction 

 could be effected without touching the insect when under examination. The Presi- 

 dent said it was the most perfect arrangement he had yet seen. 



Mr. Kirby exhibited a remarkably fine variety of Sjpilosoma lubricipeda recently 

 found alive in the Natui*al History Museum.
