of Delamere Forest Aplecta nebulosa, bred last year from var. robsoni 

 <y and var. thonrpt-oni 5 , by himself and Mr. H. Main. Only fifty 

 moths were bred, 26 per cent, of the grey form, 42 per cent, of robsoni, 

 and 32 per cent, of tkompsoni. This result quite negatives the idea 

 that the form robsoni was a heterozygote or hybrid (so called), and 

 that the grey form and thowpsoni were homozygotes, or pure. 

 Females of Lasius mixtus. — Mr. Donisthorpe exhibited three ? s of 

 Lasins tni.vtns, Nyl., a race of L. lonbratiis, Nyl., and a $ of the latter 

 for comparison. He remarked that there were only two records of its 

 capture in Britain. One was taken at Weybridge last year, and another 

 at Mickleham, when in company with Mr. Crawley, where they each 

 took a specimen last month. The third was captured this year by 

 Mr. Dollman in Richmond Park. Agriades thetis ab. coelestis. — 

 Mr. H. Rowland-Brown brought for exhibition examples of A;/riades 

 thetis [bellargus) ab. ? coelestis, Obthr., taken last August at Dompierre- 

 sur-Mer, Charente-Inferieure. He said that so far as is known at 

 present, this brilliant form of the blue $ is confined in western 

 Europe to the west and south-west of France ; roughly speaking, 

 between the valley of the Loire and the Gironde, where it 

 occurs locally not unfrequently ; the blue form of.^. coridon $, 

 var. syngrapha, also being found in the same calcareous region. 

 Hybernia marginaria. — Mr. H. M. Edelsten exhibited three generations 

 of Hybernia niarginaria, being the result of a pairing between a dark,? 

 and 5 taken wild in Epping Forest in 1908. The 1909 brood did not 

 vary much from the parents. The 1910 brood produced specimens 

 with dark margins, and three unicolorous males. The 1911 brood 

 produced specimens with lighter margins and dark inferiors, but no 

 unicolorous specimens. The darkest males and females were paired 

 in each case. These dark forms have only appeared in Epping Forest 

 the last few years. Living Beetles. — Mr. G. C. Champion sent 

 round living specimens of Cory whites purpureus and Morimus lugubris, 

 taken by Dr. Chapman at Amelie-les-Bains, Pyrenees Orientales. A 

 WooD-BORiNG Larva. — Mr. L. W. Newman showed a stick of Salix 

 capraea containing larvae supposed to be those of the " Wood Wasp." 

 He pointed out that the larvae make caps like Aeyeria andrenaeformis, 

 that the cocoon is exactly like that of a "clear-wing," and that the 

 workings resemble those of Aegeria. English Hyloicus pinastri. — 

 Mr. A. G. Scorer exhibited a specimen of Hyloicus {Sphinx) pinastri, 

 of whose British origin he had no doubt. It was caught near 

 Aldeburgh, and another specimen was taken at the same time. 

 Gynandromorphic Specimen. — He also exhibited a gynandromorphic 

 specimen of Gonepteryx rhainni, taken by himself at Salisbury, 

 on September 2nd, 1894, It was evenly divided, the right side 

 being 5 and the left 3 . Efficient Relaxing Boxes. — Dr. K, 

 Jordan exhibited some insects from India in one of Mr. Newman's 

 relaxing boxes, which had remained throughout their journey 

 as fresh as if just captured, and were in perfect condition for setting. 

 Interesting lepidoptera. — He also exhibited the Saturniid moth, 

 Dysdaemonia kadeni, in its resting attitude. The hindwings are for 

 the greater part concealed under the forewings, only the anal area and 

 the tail projecting. The abdomen being bent towards the left side, 

 the insect in this attitude resembles a crumpled dry leaf, and recalls 

 the much smaller Bombycid — also exhibited — Sorocaba anomala, 

 which, as is well known, assumes a similar attitude when at rest. He
