places where it occurs regularly. It is found also in Hezleden 

 Dene, and Mr. Gardner has bred it from birds' nests collected 

 there. This is the Tinea ganomella of Doubleday's list.

This also is a house insect, much commoner than either 

 pellionella or ixdlescentella, the larva living in the lining of 

 chairs and sofas on the hair with which they are stuffed, or on 

 wool, cloth, etc. The "Manual" says it is abundant both at 

 Newcastle-on-Tyne and Darlington, and I have no doubt it is 

 equally so everywhere ; it certainly is at Hartlepool. Mr. 

 Backhouse has marked it as occurring in Hoffal Wood, near 

 Durham, if I am correct in assuming that his T. destructor is 

 this species.

This pretty species is well distributed over both counties. 

 Mr. Finlay met with it in most parts of his district, but never 

 very commonly, In Durham Mr. Backhouse took it at St. 

 Johns, in the west of the county. It is recorded from Darlington 

 in the " Manual," and Mr. Sang took it on the railway side 

 there in 1861. It is also not uncommon in Hezleden Dene. 

 The larva feeds " on wool, etc., in nests of birds."

The larva of this insect feeds in the leaves of birch, and 

 though said to be local, appears well distributed in these 

 counties. Mr. Pinlay found it not at all uncommon among 

 birch around Morpeth. Mr. Sang got it at Wolsingham and in 

 Castle Eden Dene in May, June, and October. He also found
