on the Biononics of Southern Nigerian Insects, 385 
the open yet, and the one I have is simply lying loose in 
the box. It didn’t manage to stick on to anything. It 
possibly hangs or sticks on to the withering inflorescence 
of which the calyces at least are persistent, which may 
explain the minutely spinose pupa-case, though this char- 
acter may quite as well be protective, for the inflorescence 
is not very tomentose, at least what remains of it when the 
withered corolla falls off. . . . I am curious to see the next 
pupa. The one I have now is mottled with small dark 
green (?) spots, with a brownish ground, and would be very 
inconspicuous among half-withered vegetation. 
March 9, 1917.—1 will be able next mail to send the 
Pterocarpus Lycaenid (or two perhaps, for I’m not sure, 
but I’m dealing with two very similar-looking larvae) 
along with the others. The first of these ought to come 
out to-morrow or Sunday. Two are tachinised. Now 
I must stop this unwieldy letter. I hope I have escaped 
the Scylla of mal-observation and the horrid Charybdis 
of bad philosophy. At any rate, Pll make certain that I 
have a very good box of material for next mail. I think 
Pll send it in two lots in case one lot gets torpedoed. The 
Pterocarpus flowering is just getting finished, and I won’t 
get more material there for a time. 
The Pterocarpus pupa has a girdle fixing it to the surface 
it pupates on. In the case of the first pupa I must have 
accidentally broken this in clearing away the remains 
of the food-plant and excreta. 
March 11, 1917.—Two of my Pterocarpus Lycaenids 
emerged to-day. For the size of the larva, which is rela- 
tively large, the imago is very small, with small tails on 
the hind-wings. The first one emerged about 9 a.m., 
just before I started on my usual hunt. It was not out 
at 8.30 when I finished breakfast. In the terval I was 
getting tins ready for the foray. I did not see the second 
Lycaenid emerge, for I did not get back till a little after 
noon, very thirsty, very hot, but fairly well satisfied. 
March 18, 1917.—I have now got about 20 imagines of the 
Pterocarpus Lycaenid or Lycaenids, for I think there are 
at least two and possibly three, unless the larva is a variable 
thing. I will write details with the specimens. 
March 2, 1918.—For some obscure reason I have so far 
drawn blank in Plerocarpus, finding only three larvae, all of 
which I lost, one parasitised, the others by mould, I think. 
[One larva, taken Feb. 4, 1918, is mentioned on p. 378. ]
