LEPIDOPTEROUS PUP^E AND THEIR SURROUNDING SURFACES.

divisions A. or B. At the same time, the influence was not nearly so strong as that of 
the same colour applied at the same time to Series III. (A. and B.). So that there is 
further support for the conclusion that the latter series tended more strongly 
towards the light forms than the larvae of the company now being described. 
D. Another lot of larvae were taken (August 16, evening) from the smaller cylinder, 
those being especially selected which were as far removed as possible from suspension. 
They were placed in a cylinder (1’85 decimetres in internal diameter, and 8 centimetres 
in height) covered with a roof of gilt paper, which descended down the sides of the 
cylinder for a distance of about 1'6 centimetres. The floor was of white paper, and 
the conditions of light were similar to those of division C. The following results 
were obtained :— 
Of 3 pupae on the floor, but not fixed to the 
food-plant.. 2 were (3), 1 of them dark and 1 light. 
1 was (4), very golden. 
„ 2 pupae on the glass side, about halfway 
between the edge of the gilt paper and 
the floor, and close together (about 
1'3 centimetres apart). ...... both were (3), 1 of them light, with unusual gold for (3). 
1 pupa on the gilt roof, just above the two last, was (3). 
1 „ isolated on the roof. was (5), with plenty of gold, but not so extremely 
bright as is common. 
Of 4 pupae in a little group on the roof ... 3 were (3), 1 more pinkish than usual, 1 rather 
more golden; but neither could be 
called light (3). 
I was (2), very dark; almost a (1).

These results are very similar to the last, and suggest the same conclusions. In 
both there is some evidence for the effect of the larval bodies upon one another during 
the preparatory period. 
E. (a) On the same evening (August 16) six larvae, as far removed as possible from 
suspension, were chosen from the smaller cylinder and placed in an “ opal ” globe 
similar to that previously described (II., J.), with a glazed white paper roof and white 
paper floor. This was placed in a strong north light. When compared on the 22nd, the 
pupae had the following arrangement and colour :—All the pupae were suspended high 
above the food, and near the top of the globe upon its overhanging sides, although 
none of them were fixed to the roof.
