134 THE BUTTERFLIES OF CEYLON 
The female is very likely to be mistaken for the female 
of P. cahiva lanka, but it differs in the ground colour, 
especially of the under side. This is distinctly greenish- 
brown of a darker tint than that of P. sertata. Expanse 
about 42mm. Spots on the fore wing in I, 2, 3, 4, 6, 7, and 
8. Cell of the fore wing and under side of hind wing 
unmarked. On the under side of the fore wing there is only 
one small diffuse spot in interspace I. 
It is very rare and apparently confined to the wet zone, 
I have specimens froni Galle, Deniyaya, Ratnapura, and 
Avisawella. Mr. Mackwood also gives Punduloya and 
Lindula as localities. 
221. PARNARA (CHAPRA) MATHIAS AGNA. Chapra agna, M. 
221a. PARNARA (CHAPRA) MATHIAS SUBOCHRACEA. Chapra 
mathias, M. P. mathias, or races thereof, is found all over 
Asia and in Australia. The type of subochvacea is from 
Calcutta. 
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 conimon ; 
they fly together, and the males, at any rate, do not seem to 
grade. | 
a. agna, Smaller and darker. g spots in fore wing in 
2, 3, 4, 6, and 7 and very rarely in 8. No spot in 5. Two 
spots in cell. The spot in 2 at least twice as high as broad. 
? spots larger than in g. Two in 1 and one in 2, 3, 4, 5, 
6,7 and 8. Thatin5issometimes missing. Under side hind 
wing: Spot in cell and almost always four or more discal 
spots ; that in 6 being no larger than the others. 
b. subochracea. Larger, wings broader and paler. 3 spots 
on fore wing in 2, 3, 4, 6, 7, and 8, and very rarely in 5. That 
in 8 is sometimes missing. Two spots in cell. The spot in 
2 isroughly quadrate, at least as broad as high. 9, wings
