Prof .Poulton read notes by Mr. II. W. Simmonds of Waidoi, Viti Levn, Fiji, 

 on the protective movements of the conspicuous larva of the Catocaline moth, 

 Cocytodes coerulea Guei'., and exhibited the coloured iigure of the larva, also the 

 moth bred from the latter by the same naturalist. Prof. Poulton drew attention 

 to an observation by Mr. W. Feather at Kibwezi, B.E, Africa, on moths flying-, 

 but not at rest, captured by bats. He also read notes on Musca autmnnalis 

 De G-. {corvina F.) hibernating in a loft at St. Helens, Isle of Wight, as in 

 1914-15 and 1917-18, and exhibited six examples of the fine Ichneumonid, 

 Ophion undulatus Grav., said by Mr. Claude Morley to be common neither here 

 nor on the Continent, and bred by Mr. F. 0. Woodforde from Bomhyx qnercus 

 L. cocoons, from N. Staffordshire. He also read some observations by Mr. W. 

 Feather on the red {gregoryi Dist.) and green {speciosa Melich.) forms of the 

 Homopteron, Ityraea niyrocincta Walk., at Kibwezi, B.E. Africa, Mr. G. 

 Talbot exhibited the following exotic Rhopalocera on behalf of Mr. J. J. 

 .loicey : — A melanic aberration of the female oi Dasyoplithalma rusina Godt. ; 

 dark aberrations of the male of Papilio ridleyamis White, in which the red 

 spots of the fore wing are obscured by dark scaling (these aberrations seem 

 to correspond to the female forms oi Aa'ciea egina and zetes, and of Pseudacraea 

 trimeni,^'it\\ which the Papilio is associated), this dark aberration has received 

 the name oifumata Niep. ; a male example of the very rare and extraordinary 

 Papilio phidias Ob. from Tonkin ; and an extensive series of forms of Heliconius 

 from Matto Grosso. Lieut. E. B. Ashby exhibited various species of European 

 Orthoptera from North Italy. Mr. Hy. J. Turner, a tinted photograph of 

 the larval habit of assembly, when not feeding, of Morpho laertes (?) sent to 

 him by Mr. F. Lindeman.of Sao Paulo, Brazil, and also a coloured photograph 

 of the pupa in situ showing its close protective resemblance, and read a note 

 from his correspondent on their habits. He also exhibited several races of the 

 very variable Zygaena transalpina Esp. from peninsular Italy, sent to him by 

 Signor Querci, and stated the relationship of the various forms as explained 

 by Dr. Verity, of Florence. The Rev. F. D. Morice, a book of Charles 

 Darwin's, " Descent of Man,'' given by the author " with kind regards " 

 (autograph) to the late Mr. Roland Trimen. Mr. Morice also called attention 

 to the very abnormally developed hind legs of a female bee of the genus 

 Megadiile from Mesopotamia, apparently belonging to a section of the genua 

 in which no character at all similar had yet been described in either sex ; he 

 did not feel able to say for certain whether the character was specific, or a case 

 of monstrosity, but at present inclined towards the former opinion. Lord 

 Rothschild, two aberrant specimens of Plusia, in which genus remarkable 

 aberration is very unusual : one was a specimen of P. gamma with deep 

 purplish suffusion, the other a beautiful example of P. pulchrina taken near 

 Gloucester, June L'lst, 1919, by Mr. C. G. Clutterbuck, in which the usual 

 golden Y mark was replaced by a large wedge-shaped goldeu blotch, the space 

 between the hind margin and the subtermiual lino being of a beautiful pink 

 shade. JJr. C. J. Gahan, t-peciniens of the East African FUdidae named Ityraea 

 patvicia Melich., /. speciosa Melich., I. electa Melich., and /. gregoryi Dist., and 

 said he believed them to be all forms of the South African species Ityraea 

 ingrucincta Walk., with winch they agreed in structural characters.
