Coleoptera taken by Iiim in Nortli VV.-ilcs (on Snowdon) in the first week of August, 

 1903 — a fine series of Chrysomela cerealis, L , a pair of them being of tlie curiously 

 dull form, Antherophagus alpinu.i, P:ijk., Acidota crenata, F., Arpediurn brachy- 

 pterum, Grav., and Quediut longlcornis, Kr., the latter taken from moss on a stump 

 in the wood at the foot of Snowdon, close to the Llanberis Fails. There appears to 

 be no previous record of this species occurring in Wales. The Rev. F. D. Morice, 

 a series of lantern slides illustrating tlie structure of concealed ventral segments in 

 males of the llymenopterous genus Collelen. Mr. W. J. Kaye, a Mullerian asso- 

 ciation of black and transparent species from the Potaro Road, British Guiana, 

 consisting of Ithomiinx, Ithomia zarephi, Ithomia Jlorula, lleterosais sylphis, and 

 Napeogenes, n. sp. ; Erycinidx, Stalachtin phwdusa, a.x\{\. Stalachtis evelina ; Hy- 

 psida^, Lauron partita ; Oeometrida:, Ilyrmiua, n. sp. The whole of the specimens 

 had been caught on one single forest road, some 170 miles inland. Mr. Kaye called 

 particular attention to the new species of Napeogenes, and said it was a most re- 

 markable divergence from the usual coloration of the genus Napeogenes 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 truo 

 members of the genus Ithomia. The President, a male and female of Papilio 

 dardantts, captured in coitu by Mr. Geo. F. Leigh, F.E.S., at Durban in 1902, and 

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

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

 ever, were of the black and white hippocoon form. More recently, in 1903, Mr. 

 Leigh had captured a female of the rare trophonius 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 Oongylus gongyloides, a Mantis of the tribe Erupasides, and a floral 

 simulation," and exhibited a living $ in the nymph stage, together with coloured 

 drawings, photographs, and lantern slides showing both the adult and immature 

 insect in various positions. The chief features of interest in the exhibitions lay in 

 the peculiar modifications of shape and colouring by which the Mantis conceals itself 

 and attacks the Lepidoptera and Diptera, which constitute its prey The specimen 

 exhibited was the sole survivor of 21 brought to England in June, from Rangoon. 

 It was hatched during January, and had passed through eleven ecdyses, but failed 

 to effect the last change to the imago stage in October, 1903. Mr. G. A. J. Rothney 

 communicated " Descriptions of new species of Cryptinx from the Khasia Hills, 

 Assam, and a new species of Bembex," by Peter Cameron. Mr. Malcolm Burr con- 

 tributed " Systematic Observations upon the Dermatoptera." Dr. T. A. Chapman 

 read a paper " On a new species of Heterogynis," and exhibited specimens of this 

 and other allied species. Mr. Roland Trimen, F.R.S., read a paper " On some 

 new or imperfectly known forms of South African butterflies," and exhibited among 

 other specimens, illustrating his remai'ks, typical and aberrational forms of Acrxa 

 rahira, Zeritisfelthami, a new species, Z moloine, Trim., and Z. damarensis, Trim. ; 

 typical Colias electra, Linn., from Natal, and a remarkable melanic aberration of the 

 same species ; also Kedestas tttcusa, a very rare and unfigured Hesperiid $ and (J 

 from Johannesburg. — U. Rowland Bkown, Hon. Sec
