direct evidence that the members of the genus Nychitona are distasteful, 

 their liabits are such as to suggest this mode of protection ; and there 

 is little doubt that they have served as models for other insects. — Mr. 

 H. J. Donisthorpe exhibited examples of Dinarda 2»jgma:a, Wasm., with 

 our other three species, D. liagend, Wasm., D. deiitata, Gr., and D. 

 mdrkeli, Kies., with their respective hosts, and read a note on their 

 occurrence in this country. He also exhibited a larva of D. dentata 

 sent to him by Father Wasmann, and a larva of D. pygmica taken by 

 him in Cornwall. — Dr. Norman Joy showed the following species of 

 Coleoptera first recognized as British in 1906 : — Laccobius sinuatus, 

 Mots., from Lundy Island and Cambridgeshire, distinguished by its 

 smaller size and more parallel form from L. vigriceps, Thorns. ; Homa- 

 lota pavadoxa, Eey., taken in moles' nests in Berks and Devon; 

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

 Euplectus tomlini, Joy, from a starling's nest at Bradfield, Berks ; 

 Corticaria crenicollis, Mannh., from under bark at Basildon, Berks, 

 and at Epping ; Cardiophorus erichsoni, Buyss, taken on Lundy Island. 

 He also exhibited : — A variety of Lathrobium elongatiun, L., from South 

 Devon, with entirely black elytra, and which he proposed to call var. 

 nigrum ; a curious dull aberration of Apteropeda globosa, 111. ; Heterothops 

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

 species of Gnathoncus differing in certain characters from G. rotun- 

 datus, Kugel, and which occurs almost exclusively in birds' nests. — 

 Mr. L. B. Prout showed, on behalf of Mr. G. B. Oliver, of Tettenhall, 

 Wolverhampton, a melanic female of Acidalia marginepunctata, Goeze, 

 and a melanic male of A. subsericeata, Haw., both taken in North 

 Cornwall this summer, together with the typical forms for comparison ; 

 also a dark aberration of Ccenonympha pamphilus, Linn., taken in the 

 same district in 1903, which, on the whole, is noted for light and 

 brightly-marked forms. — The President, exhibiting a series of Selenia 

 bilunaria, drew attention to the curious angulation of the wings in these 

 examples. — Mr. H. W. Southcombe communicated a note on the for- 

 mation of a new nest by Lasius niger, the common black ant. — Mr. 

 W. J. Kaye read " Some Notes on the Dominant Miillerian Group of 

 Butterflies from the Potaro Piiver District of British Guiana." — Mr. 

 G. J. Arrow read "A Contribution to the Classification of the 

 Coleopterous Family Passalidse." — H. Rowland-Brown, M.A., Hon. 

 Secretary.

 —September 13(/i.— Mr. H. Main, B.Sc, F.E.S., Vice-President, in the 

 chair. — Mr. Goulton exhibited a long series of Calywnia trapezina from 

 the New Forest, the only species met with in several nights' sugaring 

 in August. Many were var. rufa, and a few var. ochrea. He also 

 showed larvae of Craniophora ligustri from ova. — Mr. Bellamy, series 

 of Adopaa lineola from Graveseud. — Messrs. Harrison and Main, long 

 bred series of Hadena contigua and Coremia unidentaria from the New 

 Forest. — Mr. Barnett (1) very dark bred examples of Abraxas grossu- 

 lariata from Greenwich larvae, one of which was rayed on the hind 

 wings; (2) very pale, dark suffused, and extremely dark forms of 

 Hybernia marginaria from West Wickham. — Mr. Sich, living larvae of 

 Pieris daplidice from Geneva, feeding on mignonette. — Dr. Chapman
