468 Mr. W. A. Lamborn on the 
accompany the specimens, 3 are P. aurivillia kasaiensis 
while 2 appear to be P. rotundata, var., although they bear 
the name of the former species as the determination. It 
is probable that there has been an error in the labelling 
since the specimens were received from Switzerland, and 
that the 5 ants sent by Mr. Lamborn and named by Prof. 
Forel were all kasmensis. | 
“Mar. 9, 1912: Forest 4 mile E. I captured a g 
Megalopalpus probing with its proboscis a larva of a Mem- 
bracid, probably Gargara variegata, eaten by its own larva. 
Seventeen ants, P. aurivillit kasaiensis, were in attendance.” 
The sluggishness of Megalopalpus zymna when feeding 
is well shown by the behaviour recorded in Proc. Ent. 
Soc. 1913, p. xxii. The following note gives additional 
details :— 
“ June 3, 1912. On May 28, I saw a worn Megalopalpus 
feeding, $ mile E., on a fresh leafless shoot covered with 
sticky secretion which ants were also enjoying. On May 
29 I saw the same specimen in the same position, so, with 
a view to identifying it subsequently, I trimmed its right 
hind-wing off square with a pair of scissors. When re- 
leased, it flew into a shrub near by, but it had returned 
on the following morning and was again feeding. I saw 
it again on the twig on May 30 [and on May 31 as recorded 
on the label], and I took it in my fingers and put it in the 
killing-bottle in the early evening of June 1.” 
[The following observations upon Oriental Lycaenidae 
alhed to the Ethiopian Megalopalpus have a very direct 
bearing upon the facts recorded in the present paper by 
Mr. Lamborn. HE. B. P.] 
Mr. J. C. W. Kershaw, F.L.S., in an account of the life- 
history of Gerydus chinensis, Felder (Trans. Ent. Soc. 
1905, pp. 1-4, Pl. I.), states that the butterfly lays its eggs 
towards evening, alighting “in the midst of the Aphides 
and ants, which she thrusts aside with a brushing move- 
ment of her tail, immediately laying a single egg. She 
then generally moves slightly and remains for some time 
sucking up the exuding juice of the plant; . . . The ants 
do not appear to meddle either with the butterflies or the 
eggs, though ants are very destructive to eggs of most 
butterflies, . . . Nor do they seem to interfere with the 
larvae.” Mr. Kershaw describes the larvae feeding “on 
the Aphides, sometimes pressing them against the plant 
with head and fore-legs, sometimes holding them in the
