half a dozen examples were noted, has a sooty cloud at the base of 

 the forewings and the submarginal tooth-marks unusually promi- 

 nent, while the ground colour more nearly approaches white than 

 in the ordinary pale forms. 



These aberrations were all taken some years ago, and since that 

 time I have seen no specimens calling for special mention ; indeed, 

 the species, in this locality, has of late years been much less com- 

 mon than formerly, no doubt owing to the attentions of a small 

 troop of fossilised gardeners, who spend their time from year's end 

 to year's end in " cleaning up " the banks, in other words, rooting 

 up all the little plants that they can find, on which the larvte would 

 naturally feed. Yet the species still persists ; it may be seen on the 

 wing at dusk, later in the evening on the road lamps, and by day 

 one can hardly take a walk along the parades, in its seasons, without 

 finding an example or two at rest on such portions of the rough 

 stone walls as are still free from a covering of ivy, if they take the 

 trouble to look for them. 



In the discussion which followed the general concensus of opinion 

 was that the species was a coast insect and found, as a rule, only 

 very sparingly inland. Mr. Mera said that he had met with it very 

 commonly at Ipswich, in Suffolk, but had taken only one specimen 

 in the London area. Mr. Leeds recorded one example from Bexley, 

 and another was mentioned as taken at Erith, both in Kent. Mr. 

 Frohawk also had taken a single specimen atEltham, Kent. Messrs. 

 Pennington and Bowman both reported it as common at Lewes, in 

 Sussex, where a pale form occurred. Mr. B. W. Adkin said he had 

 met with it not uncommonly in the New Forest, and more abun- 

 dantly in the Scilly Isles ; in the latter locality it was of the well- 

 speckled grey form. Mr. Tonge reported it as somewhat abundant 

 at Midhurst, in Sussex.
