25S .■ LEPIDOPTERA. 



silvery-white transverse stripe, and in the middle another, 

 more distinct, and partly divided by a black line ; Lefore and 

 beyond this are some elongated white dots, and some similar 

 clouds and streaks lie along the hind margin ; cilia white, 

 chequered and interrupted with black. Female similar. 



Undersides of all the wings smoky-brown, with the white 

 markings of the upper side more obscurely reproduced. 

 Body and legs black brown. 



On the wing in June and July and probably in a second 

 generation in October. These are the mouths in which it 

 has been taken here. Ragonot states that it flies " in April 

 and August in marshy places." 



Lakva and Pupa unknown. 



This is one of our most rare species, and cannot be looked 

 upon otherwise than as a casual immigrant. The first speci- 

 men noticed in these Islands was taken on June lljth, 1858, by 

 Mr. Thomas Boyd, flying at dusk in a swamp near Probus, 

 Cornwall. The second was taken at Lewes, Sussex, on a 

 bank at the edge of some meadows, in October 1866 by 

 Mr. G. H. Verrall. A third was found in September 1877 

 near Ashford, Kent, by Mr. W. R. Jeffreys. He says, " it 

 was flying in the afternoon in Pyrausta fashion over some 

 brambles and other dense undergrowth in a wood near the 

 top of one of our chalk hills ; so dense was the undergrowth 

 that it was with great difliculty that I used my net.^ In the 

 following year JJr. R. C. R. Jordan took a specimen at 

 " sugar " on an apple tree in his gai'den- at Teignmouth, 

 Devon ; and Mr, W. Purdey captured another at Folkestone, 

 Kent, "among long grass and rushes in very wet ground in 

 October." i In September 1880 Mr. R. E. Sahvey secured a 

 specimen near Dover " by beating hemp agrimony," and in 

 July 1889, the Rev. C. R. Digby obtained one in a grassy 

 ■hollow at Portland, Dorset. This 1 think completes the 

 record for these Islands, and it is worthy of notice that these 

 seven specimens, occurred in five difi'ereut counties — Kent,
