pleasure of Darning them. Mr. Kobson asks for lists of the Pyralids, 

 Crambids, Tortricids, Pterophorids and Tineids from any and every 

 district within the boundaries of Northumberland and Durham. To 

 those who cannot name the smaller fry, Mr. Robson also appeals, 

 stating that if they will send him their pinned captures, he himself 

 will name them. We wish the author all success in the completion 

 of his task. 



The last meeting of the Entomological Club was held on May 5th, 

 1908, at 4, Lingard's Eoad, Lewisham, when Mr. Robert Adkin was 

 the host. Tea was served by Mrs. Adkin at 6.30 p.m., and by 8 o'clock 

 a number of well-known entomologists were present. Among those who 

 sat down to supper we noticed Professor Armstrong, IMessrs. B. W. 

 Adkin, H. Rowland-Brown, J. Collin, W. L. Distant, H. St. J. K. 

 Donisthorpe, T. \V. Hall, J. Jager, A. H. Jones, R. McLachlan, G. T. 

 Porritt, F. Smith, J. W. Tutt, G. H. Verrall, &c. A most enjoyable 

 evening was spent, most of the guests leaving between 11 p.m. and 

 11.30 p.m. 



At the Conversazione of the Royal Society held on May 15th last 

 the only entomological exhibit was a case of butterflies to illustrate 

 mimicry, by Mr. S. A. Neave, and appearing in the Catalot/ne as 

 " Mimicry in Butterflies from British East Africa and Uganda." It 

 consisted of a selection from a number of butterflies collected by Mr. 

 C. A. Wiggins, which were arranged as examples of several mimetic 

 associations, and also to some extent to illustrate the transition 

 between eastern and western forms. The case exhibited by Dr. H. 

 Gadow, F.R.S., and noted as " Development and variation of the 

 Colour-Pattern in Mexican species of Lizards {Cneniidophorm and 

 Aiiwiva)," was of much interest to entomologists as dealing with a 

 parallel series of phenomena met with in insects in connection with 

 protective resemblance. The exhibit was described as follows : — - 

 "Examples of Orthogenetic variation in adaptation to surroundings" — 

 Series 1. Cnemidopliorua deppei. Sandy localities with sparse tufts of short 



grass. Stripes sharply marked, with tendency to increase from P to 11. 

 Series 2. C. fjattalus, striped race. From same locality, but less scanty vegeta- 

 tion. Mode of increase of the number of white stripes, from 6 to 11, accom- 

 panied by partial reduction. 

 Series 3. C. (/attatus, spotted race. Living in tropical forests with dense under- 

 growth. The stripes are broken up into series of pale spots. 

 Series 4. C. mexicanux. Living on the open plateau, with scattered spiny shrubs 

 and hedges. The pattern of longitudinal stripes changes in the adult to one 

 with numerous cross-bars. 

 Series 5. C. bocourti. Structurally a very slight variety of C. mej-icanm, living 

 in the same districts, but frequenting denser vegetation. The lines are broken 

 up into spots. 

 Series 6. Aiiieiva undulata. Open patches in tropical forest. Longitudinal 

 stripes vanishing with age, while new spots appear between the outer stripes, 

 become confluent and form a new white band, most conspicuous in old males. 

 We noticed the following entomologists present at the meeting : — 

 Professors T. Hudson Beare and E. B. Poulton, Dr. T. A. Chapman, 

 Messrs. G. C. Champion, A. J. Chitty, Horace St. J. K. Donisthorpe, 

 W. J. Kaye, R. McLachlan, H. Rowland-Brown, Edward Saunders, 

 and C. O. Waterhouse.
