 Hammer in August, 1900, and once by Mr. A. Piffard at Felden, 

 in Herts. 



M. nugax — Not hitherto noticed in Britain, and only recorded 

 from Erzgebirge and Frankfort-on-Main. I captured a male on 

 flowers of Spiraa ulmaria at Foxhall, in Suffolk, August 10th, 

 1902, and possess a female taken by W. Saunders in July, 1872, 

 at Greenings, in Surrey. 



M. clausthalianus. — Females. Barr, in Ayrshire, in the latter 

 half of July, 1900 (Dalglish) ; Greenings, in July, 1871 (W. 

 Saunders) ; and swept in a marsh at Barton Mills, in Suffolk, on 

 June 12th, 1900, by myself. 



M. tumidulus. — Abundant. Felden, in Herts (Piffard) ; Box- 

 hill, in September (Beaumont) ; bred from Catoptria hypericana 

 at Worksop, June 20th, 1904 (Miss Alderson) ; Greenings, in 

 June, 1871 (W. Saunders) ; Abinger Hammer (Butler) ; Shere, 

 in Surrey (Capron) ; swept from heather at Selby, in Yorks, 

 September 19th, 1902 (Ash). I found the males commonly on 

 tables of Angelica sylvestris at Foxhall on August 30th, 1899, 

 and females have occurred to me both there and at Claydon 

 Bridge, near Ipswich, in damp situations, up to September 23rd.
