DECEMBER 12th, 1913. 



Mr. Leonard Tatchell, of Bournemouth, was elected a member. 



Mr. W. J. Kaye read a paper, " The Ithoinuna; " (see page 38),. 

 and illustrated it with a very fine selection of specimens, typical 

 of the various groups of the subfamily. 



Mr. T. W. Hall referred to an occurrence of the minute acarus, 

 known as the furniture mite, CThjcipIiaijiiK cnrwr, introduced into 

 a house with some new furniture; and asked how it might bft 

 effectively dealt with. Mr. Williams suggested repeated and 

 thorough fumigation of furniture rooms. Mr. Noad Clark suggested 

 the application of a solution of corrosive sublimate in methylated 

 spirits. Several members thought that the application of the 

 latter would be detrimental to any textile fabric, and that it 

 would be dangerous if children were accustomed to iise the rooms. 



Mr. Step exhibited a box of diptera, chiefly Syrphidw, including 

 Syrphii!^ ribesii, Cataboinba pi/rastri, Eristalis pertinax, E. tenax, 

 Helophiliis pendidiis, Meseinhrina iiieridiana, etc., taken at the 

 flowers of Michaelmas daisy and ivy in October and November. 



Mr. Robert Adkin exhibited a series of Nemeophila plantcujinh, 

 reared from ova obtained from a moth taken by Mr. Lachlan Gibb 

 in the hills above Grasmere, Westmoreland, at, he believed, an 

 elevation of about 2,000 feet. The ova were deposited on July 

 3rd and 4th, 1912, and hatched on the 13th ; the young larvffi fed 

 readily on plantain, one of them growing much faster than the 

 others. This one pupated during the last week in September, and 

 produced a female imago on October 27th. All the other larv;t; 

 fed occasionally whenever the weather was warm and sunny, 

 until well into October, and appeared to make no special 

 preparation for hibernation, but simply rolled themselves up, fell 

 to the ground and lay there, usually several together, during 

 the wmter. Towards the end of March, the sunshine appeared 

 to revive them, and they were frequently on the move whenever 

 it was really bright. They began to feed again, very sparingly, 

 until the middle of May ; but from that time on they ate 

 ravenously, were all full-fed by the end of that month, and the 

 moths emerged between June 5th and 18th. The series showed 

 little variation, except that the moth reared on October 27th 

 had red hindwings, and in this respect agreed with specimens 

 received from the Orkney Islands. 



Mr. Newman said that he had never met with the species in 

 autumn, nor did he know a previous record of the red form from
