to his experience, the male-like female was rare—he only took 
it once—while the mimetic romulus, F., and polytes females 
were common. Furthermore in the Nilgiri Hills (1903), where 
he found P. hector, L., although not commonly, there was a 
form of the romulus female differing from the Ceylon romulus 
in the same manner that the Nilgiri model hector differs from 
that in Ceylon. Prof. Poulton had been informed by Dr. 
Jordan that the Ceylon aristolochiae is so variable that very 
large numbers of specimens would be required to establish 
the existence of any average difference between the species 
in this island and in 8. India.

read extracts from letters received from Dr. G. D. H. Carpenter, 
telling of his success in obtaining, for the first time, fertile ova 
from a planemoides female of P. dardanus.

“* T hasten to tell you of a stroke of extraordinary luck which 
has fallen to me. Yesterday I was out caterpillaring (there 
being very few butterflies; but I took my net as I felt sure, 
if not, I should regret it). 
“On my way home, where the track goes through the gap 
in the forest belt which I have labelled locality B, I saw 
fluttering slowly just in front of me what I at first thought was 
a remarkably large Planema; it flew just like a Planema that 
has not been alarmed. Almost at once I realised what it 
was—a Pap. dardanus @ f. planemoides—and, to my great 
excitement and joy, caught it easily. It was really doing its 
very best to pretend it was a Planema; for instead of wildly 
fluttering in the net as Papilios do, it lay perfectly still for a 
minute or so like a Planema, and remained quiet, so that I 
carried it in the net straight to my breeding-box in the forest, 
without a single flutter, although it was in the net nearly 
half an hour. It was a nice fresh specimen. 
“You will hardly believe that it is the first 2 dardanus 
I have caught myself! Save for the one hippocoon my boy 
caught (which you have received) it is also the only one I have 
seen on this island, and the ¢ I have only seen once or twice,
