destroyed in 1885. It still exists, however, in Dunham 

 . village, where the usual form is carnea 12345 ; is plentiful 

 at Cotterill Clough and Castle Mill, the commonest types 

 being libellula 00000 and rubella 00300 ; and has also been 

 taken at the following localities : — Partington, plentiful in

H. arbustorum. "Common in the neighbourhood of Jack- 

 son's boat, Cotterill Clough, Baguley, and near the river 

 Boliin, on the hedge-backings" (Dyson); " Banks of Mersey 

 and Boliin rivers, not very plentiful" (Hardy). This species 

 must have become much scarcer since Dyson's day. It is 

 still to be found in some numbers at Cotterill Clough, and 

 occasionally at Butt's Clough, in the Boliin valley ; and at 

 Gatley Carrs, in the Mersey valley.
