One of the more recent additions to our fauna. The first 

 specimen that I know of was taken at Dipton "Wood on 22nd 

 June, 1898, by Mr. D. Rosie, of Newcastle-on-Tyne. Strange 

 to say it was taken again the next day, 23rd June, 1898, near 

 Hexham, by Mr. G. Nicholson, also of Newcastle. It is an 

 interesting addition, and quite likely to be found elsewhere. 

 The larva is said to feed on Solidago virgaurea, which is not a 

 rare plant in either county.

This species appears barely to reach our southern boundary, 

 though on the western side of the island it occurs as far north 

 as the Clyde. I took it once on palings at Hartlepool, and 

 have met with it occasionally at Greatham. Mr. Sibson took 

 it at Stockton-on-Tees ; and Mr. Sang met with it at Hell 

 Kettles, near Darlington. These are all on the extreme south 

 of Durham. The imago comes to light, and I have taken it at 

 night on the windows. of Greatham Railway Station. The larva 

 is aquatic, feeding below the surface of the water on duck- 

 weed, a plant which floats about with its roots not attached to 

 the soil. Duckweed is common in small ponds and wet ditches, 

 and near such places Lemnata should be looked for.
