sea, but little- in advanpo of that in the S. of England. Witli the development of 

 insect life there was no oomparison, for in one day he had seen no less than 52 

 species of Lepidoptera. In the corner of one field were to be seen all our three 

 Melita^ce flying together. Mr. Lucas exhibited a mature and two immature speci- 

 mens of an Indian species of cockroach (Leucophfea sui-iiuimeiixis, = indica) taken 

 in the forcing pits at Kew Gardens. Mr. Montgomery, young larvse of Apamea 

 ophiogramma in the stems of the ribbon grass, and contributed notes on its habit of 

 leaving its old burrow and selecting a new stem. Mr. South, a series of Amphidaxyx 

 strataria (prodromaria), and remarked on their small size, while the larvae had been 

 unusually large. Mr. Auld, a varied series of Boarmia cinctaria taken this year in 

 the New Forest. Mr. II. Moore, specimens of the rare insect, Pseudopontia para- 

 doxa, with drawings showing its anomalous venation, its bi6d scales, and the isolated 

 position of each scale on the wing membrane ; he contributed notes on the species 

 which he said had come from Mombasa, E. Africa, and about the position of which 

 there was the widest divergence of opinion ; some authorities placed it in the 

 Rhopalocera, some in the Geometers, and some among the Bombyces. Mr. Turner, 

 on behalf of Mr. Clarke, of Reading, specimens of Tephrosia crepuscularia, taken 

 in the wood which Mrs. Bazett had said did not produce the species. Mr. Tutt 

 read a paper sent by Prof. Grote, A.M., entitled, " Autumnal Notes from the Butter- 

 fly Camp by the shores of Lake Erie." — Henry J. Tuener, Hon. Secretary. 



Entomological Society of London : May bth, 1897. — Mr. R. Tkimen, 

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



Mr. C. H. Peers, of Harrow Weald, was elected a Fellow of the Society. 



Mr. J. J. Walker exhibited an earwig, Apterygkla arachidis, Yersin, new to 

 Britain, and recently found in large numbers in chemical works at Queenborough. 

 It had been probably imported among bones. Mr. Burr also showed a complete 

 series of the British species of FurJicididcB. Mr. Enock, eggs of Stenopsocus crtici- 

 atus, L., containing parasitic larva) of Alapfux fnsculus, Hal., the male of which 

 would probably prove to be Alapius niinimicx, Hal. Mr. Merrifield, the results of 

 temperature experiments on the pupffl of Pieris Daplidice, Melitcea Didyina, and 

 other species ; he thought that changes produced by abnormal tem))erature8 might 

 be classed as follows: — (1) enhancement or diminution of intensity of colour 

 without alteration in the form of the markings; (2) substitution of scales of a 

 different colour, scattered or in groups ; (3) imperfection in the development of 

 scales or their pigment. Mr. Tutt, a series of insects collected at Cannes in March, 

 and remarkable for their early emergence. Dr. Dixey read a paper on " Mimetic 

 Attraction," in which he dealt with the steps by which wing pattern, as in South 

 American Pierinre, could be modified in various directions so as to secure a mimetic 

 result, and with the theories of mimicry put forward by Bates and Fritz Miiller. 

 Mr. I'landford exhibited and discussed scries of homoeochromatic and mimetic 

 neotropical species of butterflies, chiefly of HeliconiidcB and Ileliconioid Danaidce. 

 The discussion was continued by Prof. Poulton, who showed similar groups of several 

 genera, remarkable as having been collected and sent to England as examples of a 

 single species, and by the President, and it was ultimately adjourned to June 2nd. — 

 W. F. H. Blandfobd and F. Merrifield, Hon. Secretaries.
