66 THE ENTOMOLOGIST. 
from Whittlebury Forest in Northants, which now, I believe, 
owing to enclosure and consequent changes, no longer produces 
this genus—at any rate in the old profusion. 
Semistriana, Dsvgs. Webb speaks of this (loc. cit.) as very 
rare, and his series consists of 4 examples—2 on gilt pins 
labelled ‘‘ Bond,” 2 on black pins, probably from Clark; I do 
not find semistriana very rare in the New Forest nowadays; 
I have 12 examples from there. 
Jansoniana, Webb. Hight specimens, all from Clark, without 
data, but from Webb’s note (loc. cit.) one would infer they came 
from Epping Forest. I question this, for I have never taken 
one there; nor have I heard of anyone who has. In the New 
Forest nowadays it is not uncommon; I have 8 taken by myself 
there, and Mr. South also has some from the same source. 
Procristalana, Webb. There are 5 examples, all modern 
specimens, mounted on black pins, probably from Clark, but 
they are without data. I regard this as a very rare form; I have 
only two examples, which were obtained in the New Forest. 
The cream of the Webb series consists of the rare and beautiful 
white forms, of which there are no less than 117 examples. 
These consist of— 
Ab. capucina, Johnson. Of this rare form there are 16 
examples, all old specimens, set on white pins; 2 are labelled 
‘“‘ Burney Collection,” the others are without data, but I gather 
that the bulk of them came from the Mason Collection. 
Ab. subcapucina, Dsvgs. A magnificent series of 67 specimens, 
very variable, and including one with a black button, and several 
with pure white basal areas to the superiors. There are 26 
beautiful examples from Folkestone, taken by Mr. Purdey; most 
of the others are older specimens, mounted on white pins, half a 
dozen of which would date ante 1850; 7 of these are labelled 
‘“‘ Mason,” 2 ‘‘ Bond,” 2 ‘‘ Edwin Sheppard,” 1 ‘ Sorell (Deal),’’ 
and 1 ‘‘ Standish’; the others are without data. 
Ab. purdeyana, Webb. There are, of course, the two 
specimens Webb got from Clark, one of which is the type, and 
also two others which were included with the swbeapucina, one 
of these is labelled, in Webb’s writing, ‘‘ from Dr. Mason lot 22. 
Folkestone W. Purdey 1884”’; the other is without data. These 
Specimens are very interesting, because Mr. Purdey does not 
remember taking any previous to 1892, but there is no doubt 
but that they were pinned and set by him. There was a fifth 
specimen of purdeyana amongst the subcapucina. This is old, 
and set ona white pin. Mr. Purdey informs me that in addition 
to the 4 in the Webb Collection, which are set in his style, he 
has taken in all 7 specimens, 6 of which he possesses and the 
other is in the collection of the Hon. N. C. Rothschild. 
Ab. gumpinana, Johnson. There are 6 fine examples of this 
rare form, all old and mounted on white pins, with the following
