1906.] 71 



Mr. Edward Saunders, F.R.S., F.L S., and Mr. Charlos Owen Waterhouse, as Vice- 

 Presidents for the Session 1906-7. 



Mr. H. J. Carter, B.A., of " Ascham," Darling Point, Sydney, New South 

 Wales, and the Rev. William Henry Heale, of Wolstanton Vicarage, Stoke-on- 

 Trent, were elected Fellows of the Society 



The decease of the Rev. Joseph Q-reene, M.A., was announced. 



Mr. W, E. Sharp exhibited a specimen of Lnthrohium lasoipenne, Heer, new to 

 the British list, taken by him in a sandpit near Oxted, Surrey, in August, 191^5, and 

 for comparison therewith the nearest members of the group to which it belongs, 

 L. horeale, Hoch., L. fidvipenne, Grav., and L. angustatum, Lac. Dr. F. A. 

 Dixey, specimens of South African butterflies belonging to the Nt/mphalinse, Acras- 

 inse, Danainx, and PapiUoninx, and remarked upon the odours attaching to them 

 which he and Dr. LongstafP had observed in the field. He drew attention to the 

 significance of the fact that scents of an agreeable nature (as in Pierinse generally, 

 Mycalesis safitza, &c.) were as a rule confined to the male sex, while those of a dis- 

 agreeable or disgusting character (as in Acrxinse and many Papilios) were often 

 common to both sexes. A discussion followed on the organs and uses of scent as 

 purposes of attraction and defence in insects generally, in which the President, 

 Mr. J. W. Tutt, Dr. T. A. Chapman, Mr. G. Bethune-Baker, Mr. M. Burr, 

 Mr. Q-. J. Arrow, and other Fellows joined. Dr. G. B. Longstaff, four species of 

 Acrxa taken in South Africa during the visit of the British Association, viz.: 



(1) A. anemosa, Hew., from the Victoria Falls, and Mochudi in Bechuanaland ; 



(2) A. alhoradiata, Auriv., previously known to Mr. Roland Trimen by two females 

 only, and considered by him as a variety of anemosa; (3) ^. a^oZmi*, Westw., to 

 which he gave the names of atolniis and acontias, although there seems no doubt 

 they are one species; and (4) A. aterg at is, Westw. Professor E. B. Poulton ex- 

 hibited and read a note upon two Diptera, identified by Mr. G. H. Verrall as a 

 Chortophila, which had been observed following the bee, Andrena lalialis, Kirb., 

 by Mr. A. H. Hamm. He stated that new and interesting light had been thrown 

 on the observation by Col. Yerbury, who pointed out that both flies were males. 

 At first sight it seemed astonishing that the bees should be pursued by the males of 

 inquiline flies ; but he suggested the males in this way find their way to the 

 burrows, where they meet the females, which have also reached them in the same 

 manner, or where more probably they lie in wait for the freshly emerging females. 

 Mr. W. G. Sheldon, a collection of Rhopalocera made by him in Spain during July 

 and August, 1905, together with typical European specimens for comparison, in- 

 cluding an aberration of A. aglaia, with the black blotches on the superiors en- 

 larged and banded, and with dark suffused ground colour on all wings ; and an 

 interesting series of L. corydon and vars. hispana and polonus from Albarracin, with 

 intermediates between all these forms, and also British, French, and Swiss typical 

 .specimens for comparison. Dr. G. B. LongstafE read a paper " On some Bionomic 

 Points in certain South African Lamellicorns." Mr. Roland Trimen, F.R.S., com- 

 municated a paper " On some new, or hitherto unfigured species, of South African 

 Butterflies." Commander J. J. Walker communicated a paper entitled " Some 

 Observations on the Reproduction of Hemiptera-Cryptocerata," by Claydon Hewett, 

 B.Sc. — H. Rowland Brown, Hon, Secretary,
