 specimens of the rare Papilio mechoirianus from central Africa, 

 Anaeta cordigeua. — Mr. McArthur, specimens of Anarta cordii/era from 

 Rannoch, and read notes on its habits and habitat. Gynandromorphous 

 Papilio.- — Mr. H. Moore, a gynandromorphous example of Papilio 

 (iearchus (?) from South America, right side ^ , left ? . Aberrations 

 OF Lepidoptera. — Mr. Newman, Aglais urticae var. ielinusa, with 

 sagittate blue spots on the hindmargin, Dri/as paphia with much 

 radiated black markings, " black " Limenitis aibyllu, a straw-coloured 

 aberration of liiiinicia phlaean, the unique pale grey form of Sinerinthus 

 ocellatm bred by him in 1902, and several Hesjieria )nalcae ab. taras. 



City of London Entomological Society. — March %iil, 1909. — 

 Variation of Rumicia phl^eas. — Various European and extra-European 

 series (1) examples lighter in colour, and with black markings less 

 pronounced than in normal English specimens, from Sicily (? spring 

 brood); (2) mostly var. eleua, or abs. approaching thereto from Spain 

 (? summer brood); (3) with' black markings accentuated both in size 

 and depth of colour, but with the ground colour clear and bright, from 

 Tenerilfe ; (4) specimens with ground colour, and others with the same 

 suffused with black, from Japan; (5) with the whole ground colour 

 completely obscured with smok}' suffusion, from India, Dr. T. A. 

 Chapman. English specimens wilh copper marginal band on hindwings, 

 broken up into alternate dashes of copper and black, Messrs. S. J. Bell, 

 and L. W. Newman. A specimen with hindwings entirely black, from 

 Darenth, and var. eleus from Bexley, Mr. V. E. Shaw. Camptogramma 

 FLuviATA, from a south Devon $ . The larvje (all save two) pupated 

 on one day, and the imagines (save two) all emerged during one day. 

 Mr. H. M. Edelsten. C. fluviata larv.e, nearly full-fed, having been 

 reared on dandelion in a hot-house. Arctia caia ab. (for Mr. South); 

 with usual black markings on hindwings, restricted to three marginal 

 blotches, Mr. J. Riches. Phigalia pedaria, series bred from wild 

 Yorks melanic female ; about 10% of the offspring were melanic, a 

 few light-coloured, and the rest intermediate, forms, Mr. A. J. Willsdon. 

 MarcJi IQtIi, 1909. Stauropus fagi, taken at Hammersmith in 1863, Mr. 

 A. W. Mera. Camptogramma fluviata, bred from Bournemouth 

 female, including many examples with interrupted fascia. The cause 

 OF the scarcity or absence of a species (of Lepidoptera) which 



sometimes FOLLOWS A SEASON OF EXCEPTIONAL ABUNDANCE IN SOME 



PARTICULAR LOCALITY : Dr. T. A. Chapman opened a discussion on the 

 subject, and advanced, as a possible explanation, the theory that abnor- 

 mal abundance might be due to the temporary inactivity of some selective 

 or destructive force. Comparatively unprotected individuals would be 

 thus allowed to escape, and their unprotectedness would be transmitted 

 to, and accentuated in, subsequent broods, then, when the selective 

 agency again became active, the race would be exceptionally vulnerable 

 to its attacks, and the species would be nearly exterminated until it 

 was gradually selected up to the average of its protective potentiality, 

 and its normal number so re-established.
