NEW LEPIDOPTERA-HETEROCEHA FROM FORMOSA. 285 



swept it in woods as early as March '23rd. I took several in 

 1895, but have never seen it since that year, when it extended 

 only to May 1st, on reeds on the banks of the Gipping, near 

 Ipswich. A single old female, taken in the same district in 

 1893, is my only exponent of D. nitens; but D. picijjes is common 

 about Southwold, Tuddenham, and Ipswich, in Suffolk, and at 

 Peterborough, from April 11th to the middle of June. My best 

 species is D. tinctipemiis. Cam., of which a single female was 

 swept from last year's dry reeds in a brackish ditch on the coast 

 at Southwold on April 26th, 1909 ; this is the second known 

 specimen, but a very diligent search about the same ditch, and 

 within three miles of it, on April 20th-21st, 1910, did not 

 produce a single representative of the genus. D.fumosus I have 

 only found in the New Forest, in Matley Bog and Denny Wood, 

 in the middle of June, 1907. Our commonest kind here is 

 D. nigratus, which abounds in my paddock throughout May, 

 extending into June. The males fly swiftly in the morning sun 

 about a foot above the grass-tops. I have swept it at Foxhall 

 as early as April 8th, and found it sucking the flowers of a box 

 bush here on the 23rd of that month; it also occurs at Peter- 

 borough, Bentley Woods, and in the Isle of Wight. I need say 

 nothing of D. (Bueiis, which I have from Skene, on the borders 

 of the Scottish Highlands, to the Isle of Wight and Somerset. 

 It is commonest in June, and does not appear very early. Of 

 D. rugosulus I possess but a single example, swept from a hedge- 

 bottom at Blakenham, Suffolk, on April lltb, 1898.
