ABSTRACT OF PROCEEDINGS. 



FEBRUARY 9th, 1911. . 



Mr. W. J. Kaye, F.E.S., Premlent, in the Chair. 



Mr. L. D. Wakeley, of Wimbledon Common, was elected a 

 member. 



Mr. Newman exhibited some shoots of birch, taken from the base 

 of stumps of cut trees, which contained larvae of j^Eijeria culiciforniis, 

 or from which larvas had been taken out by birds. He had found 

 a considerable number of sticks ripped up in this way and the 

 larvae abstracted. It was usual for the larvae to feed under the 

 bark of the stumps and not in the basal growths. The suggestion 

 was that the ova are laid at the base of the vigorous first-year 

 growths around the stump, and that sometimes the larvte bore into 

 these twigs instead of into the stump. At times he had found the 

 cocoon as high as six feet from the ground. It was evident that 

 the larvae must feed in the wood of uncut trees as well as in the 

 stumps. Mr. Adkin and others had also found larval burrows at a 

 height of six or seven feet from the ground in stems of birch trees. 



Mr. Hugh Main exhibited twigs of aspen distorted and swollen 

 into galls by the attacks of larvae of the Longicorn beetle, Saperda 

 pojiiilnea. 



Mr. Ashby exhibited a series of the beetle Ladoderma seniconie, 

 and said that this species had swarmed in a house in Thames 

 Street at the end of last summer, and that these specimens were 

 some of the swarm. The house had to be fumigated and the 

 contents destroyed. At a recent meeting of the Entomological 

 Society of London Commander Walker read a newspaper cutting 

 referring to this house. 



The President, on behalf of Mr. B. Jupp, exhibited a very fine 

 variety of Ennomoa angiilaria, in which the two transverse lines of 

 the forewing were filled in with a dark fascia. The band thus 

 formed was narrower than the normal width of the space between
