This species has been found in few places in our district, but 

 not as yet northward of the Tyne Valley. Mr. Henderson took 

 it at Jesmond, where Mr. Maling found the larvae on Poplar. 

 Mr. Mcholson found larvae on Alder near Swalwell, and in the 

 Derwent Valley. Mr. Hamilton found larva in the Danes Head 

 "Wood, and Mr. Hed worth at Eowland's Mill and near Lintz 

 Green. About Hartlepool we have ako found them on Poplar 

 in gardens in the outskirts, and Mr. Gardner has taken them 

 both on Poplar and Birch in Cole Hill Wood, but not commonly. 

 The imago has never been taken. Though the larvae, with its 

 long white or pale yellow hairs would seem to be a conspicuous 

 object, it is really very difficult to recognize. Mr. Barrett says it 

 looks like a twisted downy feather. Dr. Chapman, one of our 

 most observant naturalists, says it sits on the underside of an 

 Alder leaf, quite hidden when looked at from above. ' ' In look- 

 ing up from below, through the foliage of an Alder tree, most 

 of the lower leaves are in the shade of the sun, but here and 

 there a gleam of light falls through on to a portion of a leaf, and 

 gives it quite a dijfferent appearance as seen from beneath. A 

 larva of Leporina seated beneath an illuminated leaf precisely 

 resembles one of these patches."

The only occurrence of this insect in our counties that has 

 come under my notice is that Mr. Brady took a single specimen 

 in a garden at Sunderland. As the range of the species does not 

 extend beyond the Midlands, this can only have been an acci- 

 dental visitor, possibly introduced in pupa in the bark of a trans- 

 planted tree.
