as figured by Moore. Now Bingham made rotundalis a synonym 
of silhetana , but to me it seems rather to be allied to sari , Horsf. 
Seven of my rotundalis (4d, 3 9) are decidedly “ wet ” ; the remaining 
four (1 <£ 3 9) are “ intermediate, tending to wet.” All have the 
dog’s head profile quite distinct. My eighty-four specimens of hecabe, 
all—20 S, 19 9, “dry”; 21 <J, 7 $, “wet”; 12 5 9, intermediate- 
have the black border of the fore-wing sufficiently wide to show the 
dog’s head profile clearly. In all of them there are two marks in the 
cell, and two only. In all the dry-season specimens the season-mark 
is a transverse bar clearly defined on the side towards the apex. In 
the thirty-seven silhetana, on the contrary, the narrowness of the 
black margin makes the dog’s head profile shallow, indistinct, 
or obsolete, in no less than twenty-one out of the twenty-six males, 
though it is distinct enough in ten out of the eleven females. 
Captured specimens are extremely difficult to deal with, but 
Mr. Green has been good enough to send to the Hope Department 
a number of butterflies reared from the gregarious, black-headed 
larvae; they are all clearly referable to silhetana. At present we 
seem to lack material to decide the limits of variability of T. hecabe, 
though Mr. Pryer’s results in Japan seem to show that they must 
be very wide. 1 
As already stated the Terias taken on the West Coast were all 
hecabe as above characterized. The sixty specimens taken at Kandy 
included all three forms : T. hecabe was represented by twenty “ dry ” 
specimens (10 <J, 10 9) as against three “wet” (all males), and four 
intermediate (all males). T. silhetana was represented by seventeen 
“dry” specimens (7 <$, 10 9) as against two “wet” (both males), 
and six intermediate (all males). Of T. rotundalis, on the other 
hand, there were no “dry” examples among the eight taken, but 
there were four “ wet ” (2 <J, 2 9) and four intermediate (1 d, 3 9). 
It is possibly significant that no rotundalis were taken at Kandy 
until I had been there ten days, although both silhetana and hecabe 
were common on my arrival. Is rotundalis perhaps a wet-season 
form of silhetana ? 
Not one single Ixias or Teracolus was seen during my stay at 
Kandy; moreover I seem to have taken but five specimens of 
Catophaga (Appias) paulina, Cram., 3 d, 2 9. 
The magnificent Hebomoia glaucippe, Linn., f. australis, Butler, 
was very rarely seen at Kandy, the few noticed (and it was scarcely 
possible not to notice them if present) were attracted by a Lantana 
hedge. Huphina nerissa, Fabr. f. phryne, Fabr., was seen twice only.
