TRIFID.sE. 37 



London, in 1865, by a young collector who was engaged in 

 digging for pupge ; and was recorded by Dr. H. G. Knaggs 

 under the name of Xylina Zinckenii, Tr. More recently the 

 capture of another in a similar manner, and in the same year, 

 was put upon record by the late Mr. Edward Hopley. This 

 one was found in the northern environs of London. Another 

 appears to have been taken at sugar in the following year, 

 between Dorking and Guildford, in Surrey, by the Hon. 

 Spencer Canning. The next seems to have been secured in 

 a similar manner in Darenth Wood, Kent, in 1870. In the 

 collection of the late Mr. F. Bond is one labelled "Taken at 

 Erith, Kent, September 1875, by Mr. Marshall." So far 

 as I know no other specimen was obtained for twenty years 

 until the end of September 1895, when the Kev. J. H. 

 Hocking had the good fortune to secure a specimen at sugar, 

 in his own grounds, at Copdock, Ipswich. Thus the seven 

 specimens which have occurred in this country are divided 

 between Kent, Surrey, Middlesex, and Suffolk. Abroad it 

 has a rather wide range through Northern and Western 

 Germany, Belgium, Livonia, Finland, Sweden, Lapland, and 

 some parts of Russia; also Canada, Maine, Massachusetts, 

 and New York, but known in North America as X 

 Thaxteri.
