which had been ‘‘sembled” by one female. The males were represented 
by various forms ranging from black to white, which had all been described 
as distinct species. Dr. Sharp, Mr. Hampson, Mr. McLachlan, Colonel 
Swinhoe, Mr. Elwes, Mr. Tutt, Mr. Poulton, and Mr. Jacoby took part in 
the discussion which ensued. Dr. Sharp exhibited samples of pins which 
he had tried for preventing verdigris, and stated that silver wire was the 
best material to use, as insects on silver pins remained intact, whilst those 
on gilt pins were destroyed by verdigris. Mr. G. T. Porritt exhibited a 
series of specimens representing Huddersfield forms of Polia chi, including 
nearly melanic specimens, found there during the last two seasons. He 
said these forms had not hitherto been observed elsewhere. Mr. Tutt 
exhibited a series of Hadena pisi, comprising specimens very grey in tint, 
others of an almost unicolorous red with but faint markings, and others 
well marked with ochreous transverse lines. Three distinct forms of 
Hadena dissimilis ; red and grey forms of Panolis piniperda, and a dark 
form of Hupithecia fraxinata; also a specimen of Sciaphila penziana. 
With the exception of the last-named, which was taken in Anglesey, all 
the specimens were taken or bred by Mr. Tunstall in the neighbourhood 
of Warrington. The Rev. Dr. Walker exhibited specimens of Arge titea, 
A. lachesis, A. psyche, A. thetis, and other species of the genus from the 
neighbourhood of Athens; also specimens of Argynnis phebe, taken in 
Grenada in May, 1891. Mr. W. Farren exhibited a series of specimens 
of Peronea variegana var. cirrana, and P. schalleriana var. latifasciana, 
from Scarborough; EHupecilia vectisana, from Wicken Fen; and Elachista 
subocellea, from Cambridge. Mr. G. A.J. Rothney sent for exhibition a 
number of species of ants collected by himself in Australia, in May and 
June, 1886, which had recently been named for him by Dr. Forel. The 
collection included Iridomyrmex purpurens, Sm., I. rufoniger, Lowne, I. 
gracilis, Lowne, I. itinerans, Lowne, Ectatomma metallicum, Sm., E. nu- 
datum, E. mayri, Aphenogaster longiceps, Sm., Polyrhachis ammon, Fab., 
Myrmecia nigriventris, Mayr, and M. nigrocincta, Sm.; Leptomyrmex ery- 
throcephalus, Fab., and a variety of Camponotus rubiginosus, Mayr, from 
Brisbane ; also a few species from Honolulu, and a species of Monomorium, 
which Dr. Forel had not yet determined, and which he believed to be 
probably new. Mr. C. O. Waterhouse read a paper entitled ‘‘ Some 
Observations on the Mouth Organs of Diptera,” which was illustrated by 
numerous diagrams. A long discussion ensued, in which Mr. Champion, 
Mr. McLachlan, Mr. Jenner Weir, Mr. Slater, Mr. Poulton, Mr. Distant, 
Dr. Sharp, Mr. Hampson, Mr. Elwes, and Mr. Barrett took part. Mr. EK. 
Meyrick read a paper entitled ‘‘ On the Classification of the Geometrina of 
the European Fauna.” Mr. Hampson, Mr. Elwes, Mr. McLachlan, 
Colonel Swinhoe, Mr. Tutt, and Mr. Distant took part in the discussion 
which ensued.—H. Goss, Hon. Secretary.
