that a spiinkliug of water, possibly even salt water, at or 

 near this stage of life may be advantageous. 



Pupa stout, smooth, light brown, ovoid to the end of the 

 wing covers, thence sharply conical to the anal segment, out 

 of which spring two rather large hooks. In a silken cocoon 

 among dead vegetable substances, or in the earth. (C. S. 

 Gregson.) 



The moth seems never to be found in the daytime ; doubt- 

 less it sits in crevices of rocks or among herbage. At dusk 

 it flies and may occasionally be attracted by means of sugar 

 or light ; but the vast majority of specimens in collections 

 have been reared from larvae collected at night when well 

 grown, on the plants already mentioned. Entirely confined 

 with us to rocky sea coasts, and preferring those portions 

 which lie near to high-water mark, almost or quite within 

 the splash of the waves in rough weather. Here the larvaj 

 revel in their periodically salted food plants, and the moths 

 do not wander very far. The first specimen known to have 

 been found in these islands was captured at a lighthouse in 

 August 1862, near Padstow, Cornwall, and passed into the 

 possession of that lamented artist, Mr. Edward Hopley, by 

 whom it was recorded. In August 1867 the first specimen 

 reared was so obtained by Mr. N. Greening from a larva 

 found by him in the Isle of Man. From that date to the 

 present hardly a year has passed in which that prolific 

 locality has not furnished larvEe or moths in greater or less 

 numbers. In September 1880 a single specimen was 

 secured at sugar in a little wood situated close to the sea 

 cliffs near Saundersfoot, South Pembrokeshire, by Dr. 

 Hearder. In September 1890 two were taken by the same 

 means at Ilfracombe, North Devon, by Messrs. Dixey and 

 Longstaff, and a very few more have since been captured in 

 the same district. It is said that a magnificient series of 

 specimens has been secured at New Quay, Cornwall, by 

 Dr. Eidino- ; one also has been taken at the Lizard,
