172 LEPIDOPTERA. 



with a pupa afterwards found, were reared. He found that 

 the moths paired readily in confinement, and laid their eggs 

 without delay. The same satisfactory result attended their 

 progeny, and generation after generation — three in a year — 

 were reared, and hundreds of moths distributed by him to 

 other collections. Eggs were also given away and larvee in 

 such abundance procured from them that batches were 

 turned out in various parts of the country, and even in 

 Ireland, in the hope of fully acclimatising the species. This 

 attempt was not successful, though in Norfolk the species 

 continued to exist for several years, and ultimately all the 

 colonies seem to have died out. Meanwhile there was no 

 increase in numbers in the original habitat ; a furious storm 

 stripped the poplars of every leaf, and any larvte that may 

 have been upon them at the time doubtless perished. In 

 1861 the place was again tenanted, since a larva was found 

 by Mr. Thomas H. Briggs, and others are recorded as having 

 been found in the two or three following years — though 

 rarely. In 1876 a pupa was said to have been found under 

 willow bark at Deal, and about that time another on a wall at 

 Dover. Both were reared. Two larvae seem to have been 

 found at Walmer, Kent, in 1878, but from this time I 

 find no further records until 1893, when eggs were found 

 near St. Leonards, Sussex, and the moths reared ; from 

 which source a large number has already been bred. These 

 appear to be of a darker colour than the earlier specimens — 

 which, however, have certainly faded, a little, towards brown. 

 I know of no other locality for the species in these islands, 

 yet in confinement no moth is more easy to rear and pro- 

 pagate. 



Abroad it is found throughout Central Europe, in Eastern 

 Spain, Italy, lavonia, Finland, Siberia, and in Asia Minor. 

 Also in Japan, China, India and Ceylon — but called fulgorita, 

 Walker, — and even in Java.
