II. Diptera. 
6. Exorista poultoni Villen., sp. n.: Tachinidae.—1 3, 
bearing the note “ Ex Pterocarpus Lycaenid.” The date 
was some time in March, 1917. This brilliant black species 
has been kindly described by Dr. Villeneuve on p. 518. This 
fly and the following Ichneumonid were parasitic on one 
of the species of Deudorix, probably diyllus. 
III. Hymenoptera. 
7. Adelotropis farquharsoni Waterston, gen. et sp. n.: 
Ichneumonidae, Joppinae.— Bearmg the note “ From 
Pterocarpus Liycaenid. 22.11.1917.” Described by Dr. J. 
Waterston on pp. 455-58.—E.B.P. }

Just lately the orange-yellow blossoms of a small tree that 
grows along the river-bank, at times with its roots entirely 
in the water, have been very conspicuous. The tree I was 
told was a species of Plerocarpus. To verify this and to get 
a nearer view I went down to one of the more accessible 
specimens. [The presence of an empty pupa of Argiolaus 
type just below the tree, as alluded to on p. 366,] led me to 
look rather closely at the Plerocarpus, the first non-botanical 
feature observed being the presence of Oecophylla nests, 
and workers running about the leaves and inflorescences. 
I pulled down a flower-bearmg branch very gently, it 
was the only one within reach and had to be carefully 
handled. Cecophylla is a jealous animal, éferotixoy Tt. 
Then I saw what I took to be a Limacod larva, not so 
brightly coloured as these usually are nor the characteristic 
green or yellow, but spiny and tuberculate and of a russet 
colour not unlike that of a withered Pterocarpus flower. 
Two ants were running about the inflorescence, but up to 
this point I didn’t associate them with the larva. I was 
in two minds whether I could spare the time to breed 
out a Limacod (the larva was, for one of these, rather 
small and doubtless young), and for some obscure reason 
decided to take it in. I shook the ants off the flower and 
did so. Force of habit made me examine its wonderful 
armament with a lens, and I thought. I detected a pro- 
nounced non-Limacod character. I soon satisfied myself 
that it had tubercles and a Guenée gland. Very soon I 
had in the tin a more discerning Oecophylla, which made
