demands upon their time. He observed that the extent of the subject of Entomology 

 was so vast that nothing but a systematic and continuous effort to amass collections, 

 work them out, and preserve them, could place us in a position to proceed safely with 

 the larger questions which followed the initial step of naming species; and it would 

 only be by the steady effort of our Museum officials, not only to work at the subject 

 themselves, but to enlist the aid of every available outside worker, that substantial 

 progress can be made. The President concluded by referring to the losses by death 

 during the year of several Fellows of the Society and other Entomologists, special 

 mention being made of Mons. Edmond Andre, the Duke of Devonshire, Mr. F. Grut, 

 Mr. E. W. Janson, Prof. Felipe Poey, Sir William Macleay, Mr. H. Edwards, Mr. 

 Robert Gillo, and Dr. J. M. J. Af Tengstrom.

Mr. E. Mayrick exhibited a number of specimens of Euproctis fulviceps, Walk.^ 

 taken by Mr Barnard, showing the extraordinary variation of this Tasmanian species, 

 all the males of which had been " sembled " by one female. The males were repre-

 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 re- 

 mained 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 ioxms oi Hadena dissimilis ; 

 red and grey forms of Panolis piniperdu, and a dark form of Eupiihccia fraxinata ; also 

 a specimen of SciapliiLa penziana. With the exception of the last-named, which was 

 taken in Anglesey, ail the specimens were taken or bred by Mr. Tunstall in the 

 neighbourhood of 'Warrington.
