8 eggs, 6 of which were eaten in the night by the small black 
ants, P. rotundata, var.” 
“June 3, 1912. I am sending a white Larinopoda 
which I saw deposit an egg on a dead stick. There were 
no ants on it, but they were abundant on leaves of other 
plants in the neighbourhood. 
“May 13, 1912. I saw to-day a number of the Oeco- 
phylla ants carrying off the larvae of the Saturnian moth 
Bunaea alcinée, Stoll, as they hatched from the egg.” 
The following notes refer to the relationship between 
Megalopalpus butterflies, Homoptera and ants :— 
“ Dec. 29, 1911. I took an M. zymna 2 on the same 
stem with a Membracid, L. altifrons, and 4 attendant ants, 
P. aurwillit kasmensis [3 are in the collection], all being 
so sluggish that I readily secured them between the bottle 
and cork of a killing bottle. The butterfly was probing 
with its proboscis under and around the Membracid, and 
I am quite sure that the proboscis occasionally touched 
the insect’s body.” [‘‘ Forest $ mile E.” on specimens. | 
“Jan. 10, 1912. I took two Megalopalpus $9, which 
were probing with their tongues under and around a 
Membracid, Anchon relatum, Dist. [the type of the species, 
p. 516], near to which were 2 immature and 1 mature Nehela 
ornata. Seven ants, P. aurivillii kasaiensis, were in 
attendance.” [‘‘ Forest 1 mile EH.” is on specimen, together 
with a note which apparently implies that the butterflies 
were probing the Jassids as well as the Membracid.

“Jan. 15,1912: Forest } mile KE. I obtained 2 Megalo- 
palpus [1 g only in collection] sucking food from the fore- 
wing of one or other of 2 Membracids, Leptocentrus altifrons, 
which were on a green stem, side by side and attended by 
19 P. aurwillia kasmensis.” 
“Jan. 21, 1912: Forest $ mile E. I took a § Megalo- 
palpus sucking food off the fore-wings of 3 Jassids, Nehela

Nine P. aurwillii kasaiensis were in attendance.” 
“Feb. 7, 1912: Forest 4 mile E. I took, on a green 
stem, a 2 Megalopalpus probing with its tongue and 
evidently sucking up food material from 3 Jassids, Nehela 
ornata [the type and paratypes of the species, p. 519], 
which were attended by 5 ants.” [Of the 5 ants which now
