4 THE ENTOMOLOGIST. 
The markings are perfectly symmetrical on all the wings. 
The insect, which is in perfect condition, is a male, rather under 
the average size. Altogether the variety is one of the choicest 
I have ever met with in the course of many years entomological 
experience. 
The woodeut at the head of this description has been carefully 
drawn by Mr. Horace Knight and engraved by Mr. Kirchner.

No. VI.—SEVENOAKS. 
Tue title of this article should rather have been Seal than 
Sevenoaks, but as the latter is usually the starting-point for en- 
tomologists I think it will be better known. As this treats, how- 
ever, only of one side of the town, I shall probably, at a future 
time, return in another sketch to this district. 
Sevenoaks is about twenty miles south-east of London, on the 
direct South Eastern Railway to Dover. Another way is by the 
London, Chatham and Dover line, but this is five miles longer. 
The neighbourhood of Sevenoaks peculiarly recommends itself to 
the entomologist. Surrounded on every side by either woods, 
commons, parks, or chalk downs, the collector has only to choose 
between the fauna inhabiting each kind of locality. The geolo- 
gical formation runs in bands of varying width from nearly east 
to west. Sevenoaks itself is upon the Folkestone Beds, while a 
couple of miles to the south we are upon the Weald Clay. Just 
past Seal, another couple of miles to the north of Sevenoaks, we 
are upon the Gault for a narrow strip ; while still continuing north, 
we cross a very narrow bit of Upper Greensand, between the Gault 
and the great chalk range of hills beyond. It will thus be seen that 
the collector has the advantage not only of varied localities for 
collecting, but varied soils which produce a greater variety of 
plants than is to be found in most neighbourhoods. With Seven- 
oaks town we have little to do, in what I am now about to describe, 
for we leave that town to the right as we pass from the railway 
station.
