three days at the right time appearing in some cases sufficient. Dry- 

 ness or moisture applied during the whole pupal period had little or 

 no effect on either markings or colouring. Applying the facts thus 

 ascertamed, Mr, Merrifield said he had obtained from summer pupje of 

 illustrar-ia some moths with summer colouring and spring markings, 

 some with spring markings and spring colouring, and some with summer 

 markings, but an approach to spring colouring. These specimens, with 

 enlarged and coloured photographs of them, were exhibited. Mr. C. 

 Fenn, who said he did not agree with Mr. Merrifield's conclusions, 

 exhibited a very long and varied series of specimens of Ennomos 

 autumnaria, all of which, he stated, had been bred at the same temper- 

 ature. He expressed an opinion that the presence or absence of 

 moisture, rather than differences of temperature, was one of the prin- 

 cipal causes of variation. The discussion was continued by Lord 

 Walsingham, Colonel Swinhoe, Mr. Waterhouse, Mr. Jenner Weir, 

 Captain Elwes, Mr. M'Lachlan, Mr. Porritt, Dr. Mason, Mr. Barrett, 

 and others. Mr. G. T. Baker read a paper entitled "Notes on the 

 Lepidoptera collected in Madeira by the late T. Vernon WoUaston." 

 The paper was illustrated by a number of figures drawn and coloured 

 some years ago by Prof. Westwood. Mr. Hamilton H. Druce exhibited 

 several very beautiful species of butterflies, belonging to the genus 

 Hypochrysops from the Solomon Islands and Australia, and read a paper 

 on the subject, entitled " A Monograph of the Lycaenoid genus 

 Hypochrysops, with descriptions of new species." Mr. C. J. Gahan 

 read "Notes on some species of Diabrotica." — H. Goss and W. W.

 — Mr. Wellman exhibited Bryophila impar from Cambridge, and a 

 specimen of B. glandijera, very similar to impar, from Folkestone. 

 Mr. Tugwell, a long series of Cerastis vaccinii and of C. spadicca. 

 Mr. R. Adkin, specimens of Spilosoma mendica, bred from ova 

 obtained by pairing a $ of the Irish form with a <? of the English 

 form. As a result of the brood, only two moths ( $ 's) were obtained, 

 which were dissimilar to both the ordinary Irish and English forms. 

 He also exhibited Feronea spomana from the New Forest, and referred 

 to the fact that out of some twenty specimens obtained only four or 

 five were of the variety. Mr. Cockerell exhibited Diptera and 

 Hymenoptera, showing parallel variation in colour, — the first series 

 passing from green to blue, the second from yellow to red. 



]>Jov. 21th. — Mr. South exhibited an interesting and varied series of 

 Melanippe fluduata from Ireland, London, and Scotland ; Mr. Adkin, 

 a fine series of Ardia metithastri from North Ireland, of an ochreous 

 ground colour, and varying much in the spotting ; Mr. A. J. Hodges 

 exhibited a specimen of Leucania vitellina captured this autumn in 

 the Isle of Wight, and specimens of Caradrina ambigua from the 

 Isle of Wight and Guernsey; Mr. Adye, two forms (dark grey and red) 

 of Anchoceli<i lunosa, whilst Mr. Tugwell exhibited a most interesting 

 series of magnificent forms of Triphana orbona from various localities 

 (chiefly Scotch), and T. siibsequa, mostly from Forres ; Mr. Short 

 exhibited the two broods of Lobophora virefata, which vary in size, and 

 Arctta fuliginosa, large and well-marked, from Aberdeen. — Ed.
