466 Mr. W. A. Lamborn on the 
importance,’ for I do not know where to get any more 
for identification.” 
The specimens sent under 673 are Megalopalpus zymna 
Q; larva in the forest, 4 mile E., Feb. 7; pupation, Feb. 
13; emergence, Feb. 25: Leptocentrus altifrons and the 
nymph-case from which it emerged; larva in the forest, 
Feb. 17; emergence, Feb. 23. The Leptocentrus is labelled 
“ food-insect of 673.” 
A note of Mar. 7, 1912, runs :— 
“Megalopalpus usually deposits its egg in the immediate 
neighbourhood of a colony of the food-insects, but I have 
sometimes found an egg on the egg-mass of the insect. In 
one case it was on the eggs of the Membracid, Leptocentrus 
altofrons, Walk., but I could not find this again so as to 
watch the progress of the larva, and, though I am familiar 
with the immature forms of Leptocentrus, I have never seen 
the larva eat them. [The history of No. 673 shows that 
this last statement is mistaken: see above. KE. B. P.] 
“The egg of Megalopalpus is very characteristic, being a 
circular disc with a broad flattened white margin and a 
raised bluish semitransparent centre. 
“On March 5 I found two nymphs in the same colony 
of the Membracids Gargara variegata unsheltered by ants 
and each bearing an egg of Megalopalpus : in one case on 
the right side of the dorsal surface of the abdomen just 
behind the wing, and in the other on the base of the left 
wing. [‘‘ Forest 14 miles E.” on labels of the two specimens. | 
“The larvae were on opposite sides of the stem and I 
did not examine them very closely at the time of capture 
for fear of losing them, but when I got home I found one 
eggshell empty though I did not see any larva.” 
Further notes on ants and the ova of Lycaenidae, etc., 
are as follows :— 
“ April 29, 1912. The eggs of some Lycaenids seem to 
be specially protected. I have seen a Liptena lybissa, 
Hew., deposit an egg on a dead stick, and a few days later 
I saw a Lycaenid unknown to me deposit two eggs right 
in the path of a procession of black ants running between 
the ground and their nest which was placed 20 feet up on a 
tree-trunk. The ants were all round her as she oviposited. 
‘““T have several times watched Megalopalpus zymna 
deposit a single egg among ants which have subsequently 
investigated it with their antennae but have not interfered 
with it. The eggs of various species of other families,
