96 LEPIDOPTERA. 



leaves of willow and osier in the sunshine, but is remarkably 

 like a small ichneumon fly, and may for this reason be over- 

 looked. Probably it also is timid and darts down among the 

 thick herbage which always grows about the osier stumps. 

 It was at one time common close to London, at Hammersmith, 

 and in the Hackney Marshes, as well as at Wormwood Scrubs, 

 but seems to have disappeared or to have been exterminated 

 by building operations. Also found in Kent ; in the Forest of 

 Bere, Hants ; in various parts of Cambridgeshire ; at Epping 

 Forest, Essex ; in Somerset rarely ; in Herefordshire ; and in 

 Suffolk, where it is said to have been found commonly at 

 Stoke-by-Nayland. A specimen was taken by Mr. J. B. 

 Bridgman upon the blossom of one of the smaller thistles, 

 when he was collecting Hymenoptera in a marsh near Norwich, 

 close to some willows on the banks of the Yare. It is also 

 recorded from Gloucestershire, Derbyshire and near York, and 

 probably exists in suitable places in many of the southern and 

 midland counties. Abroad it is extremely local, and not very 

 plentiful, but found in many parts of Northern and Central 

 Europe, Piedmont, Dalmatia, Greece, and Southern Russia.
