PREVALENCE IN EAST SUFFOLK O F Simyra albovenosa Goeze and of Triphaena orbona Hufn. It is of special interest to learn of the comparative abundance in the middle of August, 1957, of the Powdered Wainscot (Simyra albovenosa Goeze) in some of the marshland in East Suffolk. This insect is seldom common even in the Eastern Counties, its main head-quarters in the British Isles, though it has more recently been found to occur in restricted marshy areas of Kent, Sussex and Hampshire. Even of greater interest is the appearance in fair numbers of the Lunar Yellow Underwing (Triphaena orbona Huf.=subsequa Hübn.) This species has been exceptionally rare in recent years in the South. The only area where it still remained reasonably numerous was in the Scottish Highlands, chiefly on the sandhills around Forres. It is encouraging to know of this new region where it appears to be well established. C.

Apart from one S. ravida at light on 7.ix.57 and two atalanta on buddleia, 8.ix.57,—one with and one without the white dot, at Stowmarket, my collecting has not been in Suffolk this year. I thought, however, that the following list of lepidoptera collected at Dulwich in South-East London might interest Suffolk lepidopterists—and warn them against cities ! T h e numbers are those of the 1937 S.N.S.
