178 LEPIDOPTEKA. 



Usually verj' constant, but a varietj- has been known of a 

 nuicolorous brown. 

 On the wing in July. 



Lakva very active, grass-green with the subdorsal stripes 

 paler, and a dorsal cloudy brown spot. June and the 

 beginning of July on Si/nijjJiijtum (Corafrey), Zysiinachia, 

 Knautia arvensis, Cnitaurea scaliosa, C. nigra, Malva syhcs- 

 tris, Hubus cccsins, Serophularia aquatica, Mentha aquatica, M. 

 rotimdifolia and various other plants. 



Pupa apparently undescribed. 



The moth flies naturally from sunset to dark, and may 

 even be taken at a light at night. Its most favoui-ed locality 

 with us is Wicken Fen in Cambridgeshire, where it is 

 common ; but it is, I believe, totally absent from the fens of 

 Norfolk — certainly from all those of which I have any 

 knowledge — yet is found in some drier chalk localities, as 

 near Lewes, Worthing, and Shoreham, Sussex, and at Wye, 

 Kent. Formerly it was found at Monkswood, Hunts, and 

 very probably it exists there still, but so far as is known its 

 range in these islands is limited to Cambs, Hunts, Sussex, 

 and Kent. Abroad it has a wide distribution through Central 

 Europe, Dalmatia, Livonia, Southern Russia, North-west 

 India, Japan, and the Korea.
