may be seen swinging in a space of a foot or two square. 

 The female flies in a tolerably swift and direct manner, and 

 has been repeatedly observed to fly against, and past, a male, 

 which, so challenged, instantly follows, and both settle on a 

 leaf or twig close by. The male is provided with a moder- 

 ately strong perfume, something like that of pine-apple, and 

 not disagreeable ; when several fresh specimens are shut up 

 in a box this scent is very perceptible, and it appears to be 

 associated with the peculiar sexual habits of the species. 

 The eggs are dropped by the female loosely on the ground as 

 she flies swiftly a few inches above the surface. 



A very abundant species in woods, and on woody heaths, 

 especially among scattered undergrowth, in almost all parts of 

 England where suitable localities exist ; yet said not to be 

 common in Devon nor in the fen and moss districts of 

 Cambridgeshire, Lancashire, and Cheshire. Common in 

 Wales, and in woods in the west of Scotland ; in Aberdeen- 

 shire ; and in Perthshire, on the wooded hill-sides, as high as 

 500 feet above the sea-level. In Ireland it is abundant 

 in the wooded portions of the Counties of Wicklow, Cork, 

 Kerry, Down, and Londonderry. Found throughout Central 

 and Northern Europe, except the high northern districts ; 

 also in Eastern Asia.
