SERICORID^E—RETINIA. \\ 



known. It was recorded as British nearly half a century ago, 

 and may have been genuinely captured at that time, for there 

 exist specimens in the collection of Dr. Mason which had 

 been in that of the late Mr. Edwin Brown, and may probably 

 have been of British capture ; but all those placed under 

 this name for many years turned out to belong to the form 

 or. species here described as E. posticana, and it was not till 

 about 1890 that real and reliable R. cluplana were found by 

 Mr. T. W. Salvage at Forres, in Moray, Scotland. This 

 district, with the neighbouring county of Aberdeen, is still 

 the only locality, so far as I know, for this species in the 

 United Kingdom. Abroad it is widely distributed through- 

 out Central Europe, Spain, Scandinavia, and Western Russia, 

 and is reported from Japan, and in North America from 

 Oregon.
