The female exhibited was the sole survivor of twenty-one brought to 

 England in June, 1903, from Kangoon. 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 Cri/pton^B 

 from the Khasia Hills, Assam, and a New Species of Bembex," by 

 Peter Cameron. — Mr. Malcolm Burr contributed " Systematic Obser- 

 vations upon the Dermatoptera." — Dr. T, A. Chapman read a paper 

 " On a New Species of Heterofjyms," and exhibited specimens of this 

 and other allied species. — Mr. Roland Ti'imen, F.R.S., read a paper 

 " On some New or Imperfectly-known Forms of South African Butter- 

 flies," and exhibited, among other specimens illustrating his remarks, 

 typical and aberrational forms of Acraa rahira, Zeritis felthami (a new 

 species), Z. mulowe, Trim., and Z. damarevsis, Trim. ; typical Colias 

 electra, L., from Natal, and a remarkable melanic aberration of the 

 same species ; also Kedestas tucusti, a very rare and unfigured Hesperiid, 

 male and female, from the neighbourhood of Johannesburg, 



March 2nd. — The President in the chair. — Mr. L. C. H. Young, of 

 1, Rampart Row, Bombay, was elected a Fellow of the Society. — 

 Commander J. J. Walker, R.N., exhibited Hecatesia fenestrata, Bdv., an 

 interesting Australian moth, the male possessed of a very marked power 

 of stridulation, the stridulating organ being on the longitudinal trans- 

 parent bar on fore wing, known in N. S. Wales as the "whistling moth ; " 

 Dodonidia helmsi, Butler, a rare Satyrid butterfly from New Zealand ; 

 and a gigantic species of the Thysanurid genus Japyx, found at Picton, 

 New Zealand. — Mr. C. 0. Waterhouse exhibited and commented upon 

 a diagram of the mouth of one of the Mallophaga, L(B)iiobothiiuin titan. 

 — Mr. G. C. Champion exhibited specimens of two species of Dor- 

 cadion found during his recent journey in Spain — D. almarzense, Esc. ?, 

 from the summit of Moncayo, and D. neilense, Esc, from the Sierra 

 de Logrono. He also exhibited numerous examples of Pyropsyche mon- 

 caunella, Chapm., found by Dr. Chapman and himself on Moncayo. — 

 Mr. A. J. Chitty, Mr. F. B. Jennings, and other Fellows, exhibited 

 specimens of the genus Triopiphoms, which seemed to show that T. tomen- 

 tosus and T. obtusus were in reality one and the same species. — The 

 President exhibited a specimen of a beetle, Glenea pulchella (Thorns.), 

 one of the three individuals of the species taken on June 2otli of last 

 year, near Barwood, in the Nilgiris, by Mr. Leslie Andrewes, which 

 clearly mimics a large ichneumon fly. He said that when the whole 

 genus Glenea is examined, the marked conspicuousness of some of the 

 species suggests that the mimetic resemblance displayed by others is 

 Miillerian or Synaposematic, rather than Batesian or Pseudaposematic. 

 — Mr. L. B. Prout exhibited, on behalf of Mr. A. Bacot, long bred series 

 of Triphcena covies, Hb., the result of breeding for two generations from 

 a wild female of the cnrtisii form, taken near Forres. In the first gene- 

 ration, rather more than half the progeny followed, to a certain extent, 

 the parent female, though varying from rich deep red to almost black. 

 Pairings of these dark specimens resulted in a brood in which the per- 

 centage of ab. cnrtisii was slightly increased, although the type-forms 

 were still well represented ; but it was noticeable that in every specimen 

 the orbicular stigma was filled up with the darker or melanic colour. — 

 Dr. F. A. Dixey read a note on the " Bugong " moth, which is used for
