straight for the gland and tickled it in a way that an 
Oecophylla doesn’t usually tickle other animals. I couldn't 
reach another inflorescence, so hastened home for a more 
leisurely study. What I believe to have been a Psyllid 
jumped off the flower, but I thought there would perhaps 
be others concealed among the flowers, which are rather 
crowded. In this, as it turned out, I was disappointed. 
I got out Lamborn on the “ Relationships,’ [Trans. Ent. 
Soc., 1913, p. 436], and decided that I'd got hold of 
a larva not unlike that of Megalopalpus zymna, with a 
new attendant ant perhaps. I noticed that the pro-legs 
had the curious little protrusible “sucker”? that I have 
seen in Hewitsonia larvae and in others of the “ hairy ” 
- group, though this one is not of that type at all, being 
sluggish in its movements and of onisciform habit 
(but for the tubercles and spines, with the overlapping 
“carapace ’’ concealing the legs), and while intently watch- 
ing these details through the glass cover of the little box 
in which I'd put it, noticed for the first time that it was not a 
“ carnivore,’ but was contentedly devouring the corolla 
of one of the flowers forming the inflorescence, just like any 
ordinary, common, garden caterpillar. I had a further 
search through the “ Relationships” to see if any spiny 
form described by Lamborn had such comparatively 
refined tastes, but found, unless I have overlooked some 
detail, that his were very gross feeders and that some 
had in fact been guilty of the “ basest ingratitude,” for 
reasons well set forth therem. But I cannot persuade 
myself that he didn’t find this one, if not at Oni, perhaps here. 
I have since managed to get one or two more, but none 
have so far pupated. But I am fairly hopeful unless 
something goes wrong. 
Feb. 28, 1917.—1 rather think one or two of my Prtero- 
carpus Lycaenids are about to “go up.” If not they are 
about to “ go West.” 
I have had a further study of the larvae. Their colour 
is not the simple russet that I supposed, for on closer 
examination with a lens and by the microscope (reflected 
light) I find that there are little areas of a sort of olive- 
green colour and others of such light brown as almost to 
be yellow. The very young larva is, however, pale straw- 
coloured. The larva is very sluggish, and I got a good view 
of the tubercles in action with the aid of the microscope. 
The tubercle of this species, at any rate, is not an organ
