In the medial area are contained three stigmata (similar to those 
observable in the Noctuae), which are here correspondingly spoken of 
as the orbicular (cut A, 6), claviform (cut A, 7), and reniform (cut A, 8) ; 
and we shall find that the disposition of the two former in relation to 
the first line will enable us readily to separate the species into groups ; 
thus : — 
I. Both orbicular and clayiform 
stigmata attached to first line (cuts 
A and C). 
II. Orbicular attached, claviform 
detached (cuts B and E). 
III. Neither orbicular nor clavi- 
form attached (Plate fig. 16). 
IV. Orbicular detached, claviform 
attached (cut Y). 
In the nest place the form of 
these two stigmata themselves will 
help us to a further subdivision ; 
for instance, in group I. 
a. Orbicular and claviform both 
linear (pi. fig. 1). 
I. Orbicular and claviform both 
open (cut C). 
c. Orbicular open, or partially so, 
claviform dash-like (cut A). 
d. Orbicular and claviform in- 
distinct, owing to shading beyond 
first line (pi. fig. 11). 
Similarly group II. 
e. Claviform dot-like (cut E). 
/. Claviform dash-like (cut B), 
Again in group III. 
g. Both orbicular and claviform dot-like (pi. fig. 9).* 
h. Orbicular open, claviform dot-like (pi. fig. 15). 
i. Claviform dash-like (pi. fig. 16). 
And again in group IV. 
h. Orbicular dot-like (pi. fig. 18). 
I. Orbicular open (cut E). 
Of these sub-divisions 7 represent single species, viz., \a=pallida. 
* This species is misplaced in the plate. The numerous dark scales beyond the first line originally 
led me to include it in the fourth eubdivision— Group I, but I now see that both its stigmata are dis- 
tinctly detached from the first line.— H. G. K.
