CATALGGITE OF MOtflS. 75 



probably be found in many other parts of our district, for it is 

 generally distributed throughout Britain. The larva feeds be- 

 tween united leaves, and is therefore not easily observed. The 

 imago is said to sit on tree trunks, but it does not appear to 

 have been much seen, most of our cabinet specimens being bred. 

 Mr. Barrett says the species affects hill tops and sides, and 

 hedges in exposed situations.

This insect should be common throughout the district, but I 

 have not very many records of its occurrence. The earliest is 

 that of the Twizell list. Mr. Finlay found it at Coal Law Wood, 

 Mr. Bhagg at Chop well, and Mr. Henderson at Jesmond, which 

 are all the notices I have for Northumberland. In Ornsby's 

 Durham it is said to occur at Houghall and Maiden Castle Woods, 

 Bearpark and Castle Eden Dene. Mr. Backhouse found larvae 

 " on Thorn" at Darlington. Mr. Saug found it at Hell Kettles 

 near Darlington. Mr. Hed worth says ''plentiful always at 

 Dunston." About Hartlepool we find it commonly on the sand 

 banks, where the larvae feed on Rosa splnosissima (Burnet Eose). 

 Elsewhere on Hawthorn and most of trees, sometimes being 

 numerous enough to be classed as a destructive insect. I have 

 no records at all from the south-west of Durham, but can scarcely 

 think it does not occur there. 



The female is apterous, and deposits her eggs on the outside of 

 the cocoon. These are conspicuous objects in winter when the 

 leaves have fallen. I have sometimes found a batch in March 

 with a portion of the eggs hatched, as though part of the larvae 

 had emerged in autumn, but I never could satisfy myself this
