month, these species were found settling upon the sedge blossoms, 

 where they were joined by M. thunbergella." Hodgkinson notices it as 

 occurring about streams, and in swampy places, at Windermere ; 

 whilst Threlfall says that in the latter district it is local, but very 

 abundant where it occurs. Near Grantham it is particularly attached 

 to flowers of Mercurialis perennis, and to those of Carex in woods, and 

 flies in sunshine (W. A. Atmore). Abundant in blossoms of king's-cup 

 (Galtha jialustris) in May, and may be obtained by sweeping other herbage, 

 but always in swampy places, about Bloxworth (Cambridge). teller 

 writes : " I discovered this species in a boggy alder swamp in the woods, 

 near Glogau, Among low bushes, settling on the Carex blooms in 

 company with M. calthella. After that I found it on the flowers of the 

 Sorbus bushes, whether growing in the open or surrounded by other 

 trees. The insects seek their favourite flowers, often 10 or 12 feet 

 above the ground, from which it is difficult to dislodge them. If 

 disturbed, they conceal themselves among the blossoms, or creep under 

 the leaves. On some of the umbels a large number were found, and 

 when the bushes were shaken, some were afterwards discovered resting 

 on the grass below." Bankes says that it is found commonly in some 

 wet and mossy spots in woods and coppices near Bloxworth. 



Time of appearance. — Gregson obtained this species, by sweeping, 

 at Windermere, towards the end of May, 1870. Healy obtained it in 

 early May, 1861. Eaton captured it on June 11th, 1880, in Portugal, 

 by the streamlet near Cea. Stain ton gives the end of May and June 

 as its time of appearance. Other recorded dates are : —

 ham (Stainton) ; May 28th, 1887, near Grantham (W. A. Atmore) ; May 5th, 1890,

 at Merton (Durrant) ; May 22nd, 1850 and May 20th-25th, 1851, at Glogau (Zeller, 

 teste Durrant) .
