last November. The defoliaria showed great variation, and included 

 a dark specimen with black markings on a dark brown ground. He 

 also showed a series of H. pennaria, bred from Monkswood larvae, 

 and taken in Delamere. — Mr. K. W. Boyd, series of -H". defoliaria and 

 aurantiaria from Delamere and Borrowdale, C. boreata from Dela- 

 mere, Epunda lichenea from Penmaemawr larvae, Orthosia rufina 

 from Delamere larvae, and Hadena contigua from Borrowdale. — Mr. 

 J. Watson, specimens and live cocoons of Attacus edwardsi from 

 Assam, and several examples of a dipteron bred from a moribund 

 larva found in a cocoon. He pointed out the difference between 

 A. edwardsi and A. atlas. He also showed several specimens of a 

 species of Colias taken in Southern Uganda, at a height of 11,000 ft. 

 on Mount Kuwenzori. These were very near C. electra of the Cape, 

 and resembled our C. ednsa closely. — Mr. A. E. Salmon read a note 

 on N. ty])hcB, describing how imagines had emerged, on June 2nd, 

 from pupae found four days previously at Ashley, Cheshire. In the 

 same locality he observed half-grown larvae on July 14th, and new 

 pupae on July 31st, from which imagines emerged on September 4th. 

 This seems to point to two broods in the year. 



March 2nd, 1910.— Mr. Johnson, F.E.S., the President, in the 

 chair. — Mr. J. Watson read a paper on the Saturniidae, or silk-bearing 

 moths. After dealing with the nature of silk, he gave a detailed 

 account of the various families and species of the Saturniidae, 

 referring particularly to Anthercea mylitta (Tussore silk) and Anthercea 

 2)crnyi (Shantung silk), which are of great commercial importance 

 in view of the possible failure of degenerate Bombyx mori. He 

 illustrated his paper with long series of many species, a number of 

 live cocoons of Bhodia fiujax, Samia gloveri, Anthercea mylitta, 

 T. selcne, and others, showing the various methods of emergence, and 

 live larvae of the new Cricula andrei. Mr. Watson also exhibited a 

 specimen of Antheraa mylitta, showing the first known case of 

 regeneration of the lost part of an insect. The antennae and mem- 

 branes of one wing had been cut in opening the pupa. After emer- 

 gence one antenna was perfect, and of the other only half remained, 

 with the pectinations partly regenerated ; the wound in the wing 

 also had healed. — Mr. B. H. Crabtree, F.E.S., exhibited specimens of 

 Lyccena corydon with female varieties, syngrapha and intermediates. 



April 6th, 1910. — Mr. Johnson, F.E.S., the President, in the 

 chair. — Mr. Mansbridge, F.E.S., gave a paper on "Mendel's Theory 

 of Heredity, with Special Reference to Lancashire and Cheshire 

 Variation." By means of diagrams he showed his experiments in 

 breeding Aplecta nehiilosa and its black varieties [thompsoni and 

 robsoni), which seemed to follow Mendel's theory exactly. He also 

 gave in detail his experiments in breeding Boarmia repandaia and 

 its black variety. He exhibited these and other species to illustrate 

 his paper. — Mr. J. Ray Hardy exhibited a drawer of Coleoptera to 

 illustrate the new arrangement of the collection in the Manchester 

 Museum. — Mr. J. Watson showed living Hymenoptera bred from 

 pupae of Papilio medon, from Sierra Nevada. — Mr. A. E. Salmon 

 exhibited living Baccilus rossi, an Indian stick-insect. — A. W. Boyd, 

 Hon. Sec.
