SOCIETIES. 



Entomological Society of London. — Fehniar;/ Srd, 1904. — Pro- 

 fessor E. B. Poulton, M.A., D.Sc, F.R.S., President, in the chair. — 

 Tlie President announced that he had nominated Dr. Thomas Algernon 

 Chapman, M.D., F.Z.S. ; Dr. Frederick Augustus Dixey, M.A., M.D. ; 

 and the Rev. Francis David Morice, M.A., as Vice-Presidents for the 

 Session 1904-1905. — Mr. A. J. Chitty exliibited two specimens of 

 Ptinus tectns, Boisd., taken by him in a granary in Holborn in the 

 winter of 1892-93 ; also a complete series of the red Apions to com- 

 pare with A. sangninenm from the late Frederick Smith's collection. — 

 Mr. 0. E. Janson exhibited specimens of Vapilio ivelskei, Ribbe, and 

 Troides vierldionalis, Rothschild, recently taken by Mr. A. S. Meek near 

 the Aroa River in the interior of British New Guinea. — Mr. E. C. 

 Bedwell exhibited the following species of Coleoptera taken by him in 

 North Wales (on Snowdon) in the first week of August, 1903 : — A fine 

 series of Chrysomela cerealis, L., a pair of them being of the curious 

 dull form, Anthophnj^is alpinus, Payk., Acidota crenata, F., Arpedium 

 hrachiipterum, Grav., and Quedius longicornis, Kr,, the latter taken close 

 to the Llanberis Falls. There appears to be no previous record of 

 this species occurring in Wales. — The Rev. F. D. Morice exhibited a 

 series of lantern slides illustrating the structure of concealed ventral 

 segments in males of the Hymenopterous genus CoUetes. Mr. W. J. 

 Kaye exhibited a Mullerian association of black and transparent 

 species from the Potara Road, British Guiana, consisting of Ithoniiituc ; 

 Ithomia zarepha, Ithonna Jiorula, Heterosais sylphis, and Napeogenes 

 n. sp. ; Erycinidcc : Stalachtis j)h(Edusa, and Stalachtis evelina ; Hypsidcs: 

 Lauron partita; Geometridce, Hyrmina, n. sp. The whole of the speci- 

 mens had been caught on one single forest-road, some 170 miles 

 inland. Mr. Kaye called particular attention to the new species of 

 Xapeoyenes, and said it was a most remarkable divergence from the 

 usual coloration of the genus Napeunenes as a whole, where brown- 

 yellow and black were the prevailing colours, while the present insect 

 was black and transparent only, and conformed in a wonderful way 

 with many true members of the genus Ithoniia. — The President 

 exhibited a male and female of Papilio dardanns, captured in coitu 

 by Mr. George F. Leigh at Durban in 1902, and examples of the 

 offspring reared from the eggs laid by the female. The latter was of 

 the cenea form, as were the great majority of the female offspring ; 

 three, however, were of the black and white hippocoun form. More 

 recently, in 1903, Mr. Leigh had captured a female of the rare tropJio- 

 nius form, and had bred from the seven eggs laid by it five butterflies, 

 of which the two females were both of the commonest cenea form, The 

 female trophonius was also exhibited, together with the five offspring. 

 — Capt. C. E. Williams read a paper upon "The Life-history and Habits 

 of Gongylus yomjyloides, a Mantis of the tribe Erupasides, and a Floral 

 Simulator," and exhibited a living female in the nymph stage, to- 

 gether with coloured drawings, photographs, and lantern-slides, show- 

 ing both the adult and immature insect in various positions. The 

 chief features of interest in the exhibitions lay in the peculiar modi- 

 fications of shape and colouring by which this Mantis conceals itself 

 and attacks the Lepidoptera and Diptera which constitute its prey.
