region of large trees and fern, with here and there a wide opening or a green 

 cart track. Here C. pamphilus was very numerous, while the unbiquitous 

 F. atomaria was occasionally seen drifting before the wind, presumably blown 

 away from the heather in which it everywhere swarms. Here, too, we took 

 one C. exanthemaria and one Morellia horlorum, and found a larva of A. pro- 

 dromaria on the trunk of an oak. 



Leaving the fern and the trees we then crossed a piece of heathery ground, 

 and presently came upon the outskirts of Denny Bog. This bog we after- 

 wards found to be of considerable extent, but on the present occasion we saw 

 only a small outlying portion of it. As we neared the spot two herons and 

 nine wild ducks rose in front of us. In the marshy ground we found grow- 

 ing Orchis latifolia ; the bog myrtle [Myrica gale), and large quantities of 

 a common cotton grass (Eriopkorum augustifolium.J "While we were en- 

 gaged in getting some specimens of Orchis latifolia for drying, we were 

 joined by two botanists, who were extremely kind in giving us information 

 about the plants of the neighbourhood, and who, moreover, presented us 

 with a piece of the rare Ludwigia palustris, taken from a small pond a few 

 miles away. We walked back to Lyndhurst with them, and a heavy storm 

 of rain coming on just as we reached home, we did nothing more that after- 

 noon, though it was still early. 



We sugared in the evening in Buckett's Lawn enclosure, but with little 

 success ; two M. abjecta, one G. trilinea, and one tenebrosa, being the 

 only insects which we kept. The night was not favourable, for the air though 

 still was damp and chilly, and there was a bright moon. We took two M. 

 subtristata and two S. pectinitaria flying at dusk, and saw the usual number 

 of woodcocks and nightjars.

NOTE ON EUPITHECLE. 



By C. S. GREGSON. 



Irriguata- 



Last season a friend entrusted to my care two pupa of this species, and I 

 watched them like a cat would a mouse. They were kept out of doors ex- 

 posed fully to all sorts of weather, being covered with snow for two weeks. 

 No change in the colour of the pupa took place until the middle of April; 

 on the lGth May they were quite dark, and on the 17th the first appeared, 

 and two days afterwards the second emerged. I arrived at the conclusion 

 that the reason & irriguata is so scarce in collections is that it is over and
