38 THE ENTOMOLOGIST. 
exception of five, two of which are labelled ‘‘ Bond Collection ” ; 
one ‘*‘ Mason Collection’; one ‘‘ Webb, New Forest, 1891,’’ and 
one ‘‘ Harper Collection”; they were placed by Webb next to his 
series of xanthovittana, Desvignes, and were not named. 
I have been repeatedly asked what method I[ adopt in 
arranging the forms of cristana in the cabinet. There is only 
one method which I can conceive has anything to recommend it, 
and that is, in groups. Webb, in his paper (loc. cit.), adopts 
this method, but he does not make any attempt at a natural 
sequence. My arrangement, which I give for what it is worth, 
observing that it does not pretend to be perfection, is as follows: 
I divide the forms into nine groups, which I call the cristana, 
chantana, spadiceana, ruficostana, striana, profanana, desfon- 
tainana, cristalana, and capucina groups, and arrange them in 
the following order: 
(1) Cristana group. Forms with plain unicolorous ground- 
colour to the superiors, with or without vitta, and button, and 
including the following aberrations: Cristana, Fab., albipunctana, 
Stphs., ochreapunctana, Clark, jfuscana, Clark, nigrocristana, 
Clark, albonigrana, Clark, alboflammana, Curt., subalboflammana, 
Clark, fulvopunctana, Sheldon, xanthovittana, Desvignes, nigro- 
punctana, Clark, subvittana, Stphs., punctana, Clark, nigro- 
subvittana, Clark, unicolorana, Desvignes, and subunicolorana, 
Clark. 
(2) Chantana group. Forms with the front half of the 
superiors from a line drawn from the inner margin of base to 
near the apex chestnut colour, including abs. chantana, Curt., 
postchantana, Webb, prochantana, Ciark, subchantana, Clark, and 
vaughaniana, Webb. 
(3) Spadiceana group. Forms with the front half of the 
upper wing from the inner margin of base to near the apex 
different shades of brown, including abs. spadiceana, Haw., 
vittana, Stphs., intermediana, Clark, brunneana, Stphs., swb- 
striana, Stphs., and rufinigrana, Clark. 
(4) Ruficostane group. Forms with the front portion of the 
superiors from the inner margin of the base to a point on the 
costa near the apex dark brown or black, the other portion of 
superiors, with the exception of the inner margin, being grey. 
Button very small or not existing, including abs. ruficostana, 
Curtis, alborujicostana, Clark, attaliana, Clark, nigrocostana, Clark, 
and transversana, Clark. 
(5) Striana group. Forms with the disc of the superiors plain 
brown or black, but with lighter markings in the anal angle, and 
the vitta striated with dark lines including abs. striana, Haw., 
prostriana, Clark, merlana, Clark, insulana, Curt., and fulvostriana, 
Desvignes. 
(6) Profanana group. Forms with superiors brown or black 
more or less mottled with darker colour, including abs. profanana,
