364 Mr. C. O. Pas Meaieoal Five Years’ Observations 
in Trans. Ent. Soc. Lond., 1907, Pl. II, fig. 8, represents 
only a single hind-wing tail—the central one—although 
the type possesses all three. In the text (p. 81) and also 
in the original description (Ann. Mag. N.H. (Ser. 7), vol. 
xi, 1903, p. 71) there is an inadvertent error in the state- 
ment that the insect lacks the row of hairs on the inner 
margin of the hind-wing under surface. The fore-wing 
is, of course, intended. The absence of the patch of 
special scales on the shining area of the hind-wing upper 
surface where it is overlapped by the fore-wing, and of 
the hairs on the fore-wing under surface by which, in other 
species of the genus, these scales are covered, is emphasised 
by the name mirabilis, and leads the author to remark 
that the species “‘seems to open up the question very 
forcibly as to whether distinctive genera can be made 
on the absence or presence of these ‘sexual marks.’ It 
appears to agree in venation exactly with Hpamera.’—

July 26, 1915.—I got to Lycaenid tree No. 1 [ Alstonia 
congensis Engl.| from which the Hewitsonias are obtained, 
and was looking intently at the bark from different angles. 
I got nothing on the tree at that time and passed on to 
the next one. Here Lamborn found that extraordinary 
gall-like pupa [Argiolaus maesa Hew.]. I had the great 
luck to get a larva which has since pupated. I also found 
on a small shrub at the base of the tree a pupa of another 
species [Argiolaus alcibiades Kirby]. I can hardly hope 
that it is one Lamborn didn’t get. It was on a leaf. Its 
shape, with the broad tail attachment, in general resembled 
the other, but it is not really gall-like. Unfortunately at 
the head end which appeared to rest on the leaf, there 
appeared to have been a slight exudation of the living 
matter. The pupa was a dull olive-green colour. I took 
it in, however, in hopes that it might not be irretrievably 
damaged. Yesterday a wretched Ichneumon emerged. But 
just in case Lamborn didn’t get it, I went back yesterday 
and on another little group of shrubs, hardly more than 
seedlings, I actually got two healthy-looking pupae, of 
an apple or Alga green—not shining but dull green like 
the surface of a tomentose leaf. There had been a third 
one which had got damaged and was being eaten by little
