SOME NOTES ON REARING EREBIA EPIPHRON. 61 
possessed an anal attachment, but when turning one of the pupe 
out of the tumbler I noticed that it hung by the anal segment by 
a strand (or strands) of silk. My impression is that all the pupe 
were not so attached, and in any case the attachment was but 
slight. In all four cases, as I have noted above, pupation took 
place at the bottom of the tumbler, and in all four cases the 
larva, during the change to the pupal state, was touching, if not 
actually resting on, the blotting-paper; after the change the 
pupa was resting on the paper, and did not depend on the strands 
of silk for its support. In three instances the larve went through 
the process of pupation with the dorsal surface on the blotting 
paper and the ventral surface uppermost; but in the fourth 
instance the position was reversed, and the ventral surface of the 
larva remained throughout on the blotting paper. After the 
puparium had been spun, the larva remained quiescent for some 
time preparatory to the change to the pupa. I am under the 
impression that one day was occupied in making the puparium 
and settling down for pupation, and that about two days were 
passed in the quiescent state; but this is a point upon which I 
cannot speak with any certainty. Nor can I say anything with 
regard to the operation of changing or the time thus occupied. 
The larva retains its green colour throughout, and the newly- 
formed pupa is of a bright transparent green, this colour, of 
course, not retained throughout the whole pupal state, but little 
change can be detected for some days, the only difference being 
that the colour gets slightly duller and less transparent. Dr. 
Chapman's description of the fourth pupa* was made when it was 
four or five days old; it may be well to mention also that this 
pupa produced a 2 imago, and that Mr. Tonge’s photograph 
shows the same pupa, for this pupa was more dumpy than that 
which produced the ¢ imago. 
I kept the fourth pupa under observation, and took some 
notes of the changes in colour which preceded emergence. On 
September 380th I observed the first decided change in the 
appearance of the pupa. A distinct, though not striking, change 
in coloration had taken place between the date of pupation 
(September 18th) and September 30th, the green colour having 
lost in brightness and intensity and the pupa being altogether 
of a much duller appearance, but this change had been so gradual 
that, until September 30th, it was not possible from one day to 
another to observe any perceptible difference in the colour of the 
pupa. On September 30th, however, the appearance of the pupa 
showed a distinct advance on that of the preceding day. I will 
give the notes as I took them down, commencing with the date that 
showed the first decided change in the appearance of the pupa. 
September 30th, forenoon : The eyes have assumed a brownish 
tint ; there is a slight darkening about the mouth-parts. The
