of Strenia clathrata ocourring at Streatley, Berks., in August — all taken this year. 

 Mr. G. T. Porritt, a series of Abraxas grossidariata, var. varleyata, bred tliis year 

 from a pairing of the variety obtained from wild larvge the previous season at 

 Huddersfield. All the brood were of the variety, none showing the least tendency 

 to revert to the ordinary form. Mr. C. P. Pickett, a gynandromorphous specimen 

 of Angerona prunaria bred by him, and a male specimen of Fidonia atomaria, 

 caught at Folkestone, with six wings. Professor Charles Stewart, F.R.S., a remark- 

 able unnamed exotic larva, found in a collection of specimens received at the 

 College of Surgeons, displaying a series of iridescent spots about the spiracles. 

 Mr. W. J. Lucas, on behalf of Messrs. F. W. and H. Campion, specimens of the 

 rare dragon-fly Sympetrum flaveolum, taken near Epping in August last, and read 

 an account of their capture, in which it was suggested that these were part of 

 a migration of the species such as occasionally takes place. Dr. F. A. Dixey, 

 specimens of Nuchltona medusa, Cram., Pseudopontia paradoxa, Feld., Terias 

 senegalensis, Boisd., Leuceronia pharis, Boisd., and L. argia, Fabr., remarking that 

 although there does not exist any direct evidence that the members of the genus 

 Nychitona are distasteful, their habits are such as to suggest this mode of pro- 

 tection ; and there is little doubt that they have served as models for other insects. 

 Mr. H. J. Donisthorpe, examples of Dinarda pygmsea, Wasm., with our other three 

 species, D. hagensi, Wasm., D. dentata, Gr., and D. marJceli, Kies., with their 

 respective hosts, and read a note on their occurrence in this country. Also 

 a larva of D. dentata sent to him by Father Wasmann, and a larva of B. pygmxa 

 taken by him in Cornwall. Dr. Norman Joy, the following species of Coleoptera 

 first recognised as British in 1906: — Laccobius sinuatus, Mots., from Lundy Island 

 and Cambridgeshire, distinguished by its smaller size and by its more parallel form 

 from L. nigriceps, Thoms. ; Homalota paradoxa, Rey, taken in moles' nests in 

 Berks, and Devon ; Quedins vexans, Epp., and its larva, from moles' nests in Berks. ; 

 Sitplectus tomlini, Joy, from a starling's nest at Bradfield, Berks. ; Corticaria 

 crenicoUis, Mannh., from under bark at Basildon, Berks., and at Epping ; Cardio- 

 pkorus erichsoni, Buyss,, taken on Lundy Island. Also a variety of Lathrohium 

 elongafum, L., from South Devon, with entirely black elytra, and which he proposed 

 to call var. nigrum-, a curious dull aberration of Apteropeda globo.sa. 111. ; Retero- 

 thops nigra, Kr., taken in moles' nests from various parts of the country ; a species 

 of Onathoncus differing in certain characters from G. rotundatus, Kugel., and which 

 occurs almost exclusively in birds' nests. Mr. L. B. Prout, on behalf of Mr. G. B. 

 Oliver, of Tettenhall, Wolverhampton, a melanic ? of Aoidalia marginepu aetata, 

 Goeze, and a melanic $ of A. suhsericeata. Haw., both taken in North Cornwall 

 this summer, together with the typical forms for comparison ; also a dark aberration 

 of Coenonympha pamp}iiluf!,\jmn.,iKken in the same district in 1903, which is on 

 the whole noted for light and brightly-marked forms. The President, a series of 

 Selenia bilunaria, drawing attention to the curious angulation of the wings in these 

 examples. Air. H. W. Southcombe communicated a note on the formal ion of 

 a new nest by Lauus niger, the common black ant. Mr. W. J. Kaye read " Some 

 Notes on the Dominant Miillerian Group of Butterflies from the Potaro River 

 District of Britisli Guiann." Mr. G. J. Arrow, " A Contribution to the Classifica- 

 tion of the Coleopterous Fainily Passalldx.'" — H. Rowland Brown, M.A.,
