 tris, Ficia sylv^tica, i^actuca virosa, Neottia spiralis (in greater 

 abundance than I have elsewhere observed it), Carpinus J5e- 

 tulus, t/uniperus communis, //ippophae rhamnoides. On the 

 cliffs and sea-beach, some of the usual maritime plants are 

 found, such as Crithmum maritimum, Glaucium flavum, ^Sta- 

 tice binervosa (see Eng. Bot, Supp,, pi. 2663.), Beta, maritima, 

 &c. But the coast immediately about Dover, it strikes me, is 

 not very rich in what are termed maritime plants.

-|- Of this species, which, it is well known, occurs plentifully in particular 



-seasons, while in others it is hardly to be met with, there was a consider- 

 able flight in the neighbourhood of Dover during the months of August 

 and September. If I mistake not, it occurs principally in maritime coun- 

 ties : I do not mean that it is confined to such situations, but that it is met 

 with far more copiously nenr the sea-coast than elsewhere. The only places 

 in which I have ever seen it in any thing like abundance are the Isle of 



.Wight, and the opposite coast of Hampshire, in the year 1804; and this 

 season, in the neighbourhood of Dover, viz. near the signal-station to the 

 east ; St. Margaret's Bay ; near Folkstone, and between that town and 

 Sandgate ; some specimens also near Hythe and Canterbury. In Warwick- 



' shire, and the midland counties, I never saw more than two, or at the 

 most three, specimens on the wing ; and those in different seasons, 1808 

 and 1811.

 to be a distinct species, and, as such, published in Haworth's Lepidoptera
