of Populi. The resemblance of an ocellatus larva to one form 

 of those of Populi makes it easy to understand how they were 

 not distinguished as larvae. The same year (1874) Mr. Wm. 

 Fleetham found on 3rd July an example of the perfect insect, at 

 rest on some palings formed of old sleepers, on the railway side 

 at Hartlepool, and not two miles from where Mr. Gardner had 

 found the larvae. Also, in the same year, Mr. Hed worth found 

 a full-grown larva at Darns Head, Axwell, which, in 1875, pro- 

 duced a specimen that afterwards passed into the collection of 

 Mr. Wasserman, and is now in the l^ewcastle Museum. In this 

 year (1875) an example came into my possession which had 

 been taken near Hartlepool. Twenty years have elapsed since 

 then, but I have met with no further record of its occurrence 

 in either county, until the present year (1896), when Mr. J. 

 Ehagg bred the imago from larvae found on Willows at "Wylam 

 on the Tyne.

This is the commonest of the large Hawk-Moths and the most 

 widely distributed in both counties. 



Por Northumberland it is given in the Twizell list, and in 

 Stephen's "Illustrations of British Entomology" (Haustellata, 

 vol. 1, p. 113), it is mentioned as occurring in I^or thumb erland 

 on the authority of the late Mr. Hewitson. Mr. Finlay reports 

 it as generally distributed in the neighbourhood of Morpeth, 

 and Mr. Maling, Mr. Henderson, and others have taken it 

 around Newcastle. In Durham Mr. Hed worth found the larvae 

 " generally common on Poplars throughout the district." This 

 refers more particularly to the valley of the Derwent and the 

 south banks of the Tyne. It is given in the list in Ornsby's 

 Durham, and Mr. John Wood (Ent. Mon. Mag., vol. 2, p. 150)
