a moment denying that it is quite possible that a larva might undergo 
a groat number of changes of skin when being fed up in an abnormal 
temperature at an unnatural time of the year, the fact remains that 
of 50 larvae kept under observation, none except the forwards had 
undergone more than three moults, that is to say, reached their 4th 
skin by February 14th. Again, Dr. Chapman notes that it is in the 
5th skin that the larva hybernates, whilst all mine did so in the 4th. 
I do not lay much stress on the results I obtained as differing from 
those obtained by Dr. Chapman, because 1 believe that the exceptionally 
mild winter and the indoor position of feeding would probably have a 
large influence on the number of moults. I failed to detect any 
fuliyinosa- plumaged larvae, all mine passing direct from Spilosoma to 
rain plumage. As to whether forwards exist in a state of nature, I 
have in bygone days seen larvae in adult clothing in the autumn, when 
that has been mild through the prolongation of the summer, but as I 
invariably left them out of doors for the winter, they always died, and 
I got the idea that they could not hybornate in caia dress. This, 
Dr. Chapman appears to confirm, as he says that some aberrant 
normals prepared to hybornate in distinctly caia plumage, but does 
not say that they actually succeeded in doing so. Even if they did so 
hybernate, that would be no proof that wild ones could do so also, as 
Dr. Chapman was apparently breeding indoors.” Mr. Clark said 
that this species should be hybernated out of doors, and kept exposed 
to all weathers. They were usually kept too dry. Mr. Fenn re¬ 
marked that all hairy lame arc apt to die of mould. He described an 
excellent method of hybernating the lame out of doors, by placing a 
sloping piece of glass over the top of the tub or other vessel in which 
they were confined, to keep the rain off. Mr. Heasler queried the 
action of food on the coloration of the wings. Mr. Nicholson said 
that several bred specimens had a tendency to yellow hind-wings, 
although perfectly healthy. A vote of thanks to Mr. Bate terminated 
the proceedings. 
April 6th, 1897.— Cidaria immanata from Raindene Wood.— Dr. 
Sequeira: a series of Cidaria immanata from Raindene Wood, near 
Folkestone. Xyleborus saxeseni from Richmond Park.— Mr. Heasler : 
a series of Xyleborus saxeseni from an oak stump in Richmond Park 
last November. He said : “ This species belongs to the group which 
bore into the solid wood, and are usually difficult to obtain, especially 
when they take to oak. The whole of my specimens, however, were 
taken in the bark in company with Dryoeoetes villosus, Placusa pumilin, 
Rhizophayus ferruginous, etc.” 'L'.eniocampa populeti. — Mr. Taylor: a 
series of Taenioeampa populeti from Wimbledon, illustrating the entire 
range of variation of the species in this district, and including speci¬ 
mens of ab. obsoleta, Tutt, and ab. intermedia, Tutt. The Lepidoptera 
of the Isle of Dogs. —Mr. Woolley read some “ Notes from the Isle 
of Dogs.” He gave a list of the Lepidoptera to be taken on the 
island, and exhibited many of the species and some plants. The 
particular piece of ground from which all these were taken was about 
a mile square, and was constantly used by the Millwall Dock Company 
as a receptacle for the mud which is dredged from the bottom of the 
dock. The land was divided into three parts, and each division was 
flooded with mud every third year. The following is a list of the
