Lachnocnema bibulus—2 g 3 9. One 3g and one @ 
pupated March 13, 1917, and emerged March 22; a second 
female emerged on the same day, all 3 with precise pupa- 
cases; a third female emerged at Ogo, March 25. The 
first-mentioned female bears the note “ Larva on secretion 
of ant-attended immature Membracids on small Leguminous 
shrub,” the other specimens a shortened form of the same. 
The second § emerged Jan, 4, 1918. It is accompanied 
by its case and the note “Jassid-eater. New series, 
formerly found eating Membracids (1917).” 
The attacks of this larva upon ant-tended Jassidae are 
deseribed by Lamborn (Trans. Ent. Soc., 1913, pp. 470-1), 
and he thought, but was not sure, that the ants fed it. 
Farquharson’s notes add greatly to our knowledge of the 
larval habits and food. For a brief preliminary statement 
see Proc. Ent. Soc., 1917, p. 1xi.] 
March 11, 1917.—I have seen another Lycaenid, probably 
one of those found by Lamborn, but perhaps my observa- 
tions may complement or corroborate his. This one is 
part of a Membracid association along with a small black 
ant that habitually lives in the débris that collects in Oil 
Palm heads but forages down below. I once had two fine 
nests of them last year, many of the callows having mite 
“balancer ’”’ parasites. I lost the lot owing to my having 
to go travelling, most inopportunely, but I hope to do 
more on them later. They are probably a Pheidole. The 
Membracids (adults and nymphs) I found in a small 
Leguminous shrub at the base of a Palm, I think a Tephrosia, 
but it isn’t flowering and I’m not quite sure. At any rate, 
it is the host of a very large number of Membracids, a 
much larger number of ants, and a few Lycaenid larvae. 
The larva, so far as I can make out, is without Guenée’s 
gland and tubercles. It is rather bristly; the head pro- 
tected by the usual “carapace.” Its colour is a curious 
blend of the Membracid colour with additions. In appear- 
ance it reminded me very much of a large Syrphid larva 
that I found in Shagamu last tour eating Aphids, and that 
larva resembled a bird-dropping more than anything else. 
The young larva is rather more bristly than the older ones 
and is less “ ornithoscatoid.” The little shrub is only 
about three feet high, and I could sit down more or less 
comfortably to see what they were doing. In the forenoon 
I couldn’t make out what they really were doing. I 
remembered enough of the “ Relationships” to expect to
