176 SPOLIA ZEYLANICA. 
from the Andamans ; it differs from all large Ceylon Parnaras 
(except conjuncta), in having two large spots in the cell. i 
have seen nothing like it in Ceylon. 
I consider pencillata a great rarity. Till last year my only 
specimen was one given to me by the late Mr. Butt, of Avissa- 
wella, in 1889. I have now received one each from Galle and 
Deniyaya, and Mr. Mackwood has given me two from Ratna- 
pura. 
It is apparently confined to the wettest zone.

C. mathias, or races thereof, is found from Turkey to Japan, 
and in Australia. 
Moore gives mathias and agna from Ceylon, and says agna is 
larger than mathias, and has smaller spots. Personally I 
find that the form with the small spots is usually the smaller 
insect. Elwes and Edwards agree with Moore in dividing it 
into two species, naming the one with the small spots mathias, 
and the one with the large subochracea. There are certainly 
two distinct forms in Ceylon which are extremely common ; 
they fly together, and the males, at any rate, do not seem to 
grade. 
The male of the large form, with large spots, is much 
lighter in colour both above and below ; the fore wings are 
broader in proportion to their length, and the hind wings 
more rounded. The females show this difference in the shape 
of the wings to a greater degree than the males. There is 
little variation in either form in the number of spots on the 
fore wing ; the males of swbochracea usually have a spot in 
interspace 8, which is seldom present in mathias ; all the 
females of both forms in my collection show this spot. A spot 
in 5 is present, more often than not, in both females, but it is 
only traceable in two of my specimens of male subochracea. 
The differences in the prehensores are exceedingly minute 
and hard to see, though they are apparently constant ; the 
chief one lies, as pointed out by Elwes and Edwards, in the 
apex of the tegumen. Personally I attach much more
