January 26th. These photographs showed the mycelium spreading 

 in a radial manner, and attaining to a felted texture tvfo inches in 

 thickness. Hundreds of square feet of woodwork had been covered 

 with this destructive growth ; and in addition it had attacked 

 linoleum and carpets. (Plates II. and III.) 



Mr. Robert Adkin exhibited a form of Xula albidaliA, from East 

 Sussex, in which the broad brown cloud that in ordinary specimens 

 occupied the central area of the forewings was absent, leaving only 

 the darker transverse narrow stripe, thus giving the insect a much 

 paler and more sharply marked appearance than is usual. He said 

 that some thirty years ago he both captured and bred a considerable 

 number of Kentish specimens of this species but so far as memory, 

 assisted by a long series in his cabinet went, they were very uniform 

 in appearance, but among the few that he had seen of recent years 

 from the Sussex locality were several approaching the form 

 exhibited. 



The President exhibited several Syntomid species, of the genus 

 Psi'uildsphc.v, including P. Jonesi n. sp. and /'. norerea, to call 

 attention to the remarkable tufted basal joints of the palpi. The 

 long black hair made these organs wonderfully like the jaws of 

 the several species of wasps that they mimicked. A further species 

 of Syntomid was shown — Splieconoma te^tacea, together with its 

 model a Pompilid species of wasp of the genus Psenihtnenia. This 

 wasp had only very slightly developed jaws and the Syntomid 

 mimic had no such clothing to the palpi as was found m 

 PxendnspJiex. 



Mr. Sheldon exhibited two specimens of a Xoctiia, concerning 

 which there had been keen controversy some thirty years ago. 

 They were taken about 187-i by a young collector named Taylor, at 

 Derby, and forwarded to various authorities without being definitely 

 determined. They were named by Knaggs Aurotis kelvetina as new 

 to Britain, he identifying it with a continental species ("Ent. Mo. 

 Mag.," vol. viii., p. 182). The specimens eventually came under 

 the notice of Dr. Mason, who, after some trouble, made them out 

 to be a form of (Traphipliora atu/ur, with " the ground colour light 

 grey or putty colour ; the two black lines crossing the front wing, 

 and those outlining the discoidal spots are there, but are not so 

 pronounced as in the type, the fringe on the hind wings is pink, not 

 grey." (see "Brit. NoctufB," vol. ii, p. 103). 



Mr. Blenkarn exhibited an example of Kpinephele titJwnns of a 

 very pale xanthic colour ? ab. albida, taken in the Isle of Wight in 

 July, 1910 ; a semi-scaleless form of SatHmia pavunia : the form
