portions of the ege structure proper, but of the same adventitious 
material that ornaments the eggs of blue butterflies and is found also 
in Theclas, and in most cases more developed in the lower zones. The 
upper portion of the side B-C, projects to about the level of the tops of 
the ribs, or if anything a little further (see pl. II.,fig.1). This portion 
is very dark brown and is continuous on over the top to D; as far as C, 
it is clothed with fine hairs, or rather hair-like processes, probably 
arising from the angles of the cells. Just as this dark portion subsides 
below into the less prominent sides, so it slopes downwards on top to 
the shallower basin. This portion in the living egg is probably quite 
flat, it is very pale compared with the margins and the central micro- 
pylar area is paler still. 
The base of the egg is colourless, but a netted structure of cells can 
be made out, the cells rather larger than the largest on the top. The 
sides are of probably similar cellular structure, which would be seen if 
the adventitious coating forming the surface were removed. ‘The top 
is shown in pl. IL, fig. 1. 
It should be explained that an egg was divided horizontally at the 
line B. Fig. 1 and 2 are views from above of the two portions. In 
interpreting the upper portion (fig. 1) it must be noted that it has the 
whole depth of from B to C (text figure) and so cannot be all properly 
focussed, and so, in focussing the flat top, the cut margin also happens 
to come nearly in focus, whilst the portion of the top that comes 
against it is out of focus and the cells are not visible. It will be easily 
understood, keeping this in mind and comparing it with pl. L., fig. 1. 
It shows the hair-like processes of the margin, where they come in 
profile. The netting on the top is fairly hexagonal, but not strictly so 
as the cells are larger near the centre. Towards the margin they are 
about 0:018mm. in diameter, a little further in 0-02mm., and towards 
the micropylar area 0:026mm. In the micropylar area the cells are 
much smaller and narrowly lanceolate with the long diameters radial. 
The eggs that had hatched are all nearly uniform in showing that 
that larva made a central circular opening, that left a margin of pale 
area within the dark border zone, actually O‘Smm. to O-6mm. in 
diameter.

These two specimens include the whole egg, which proved to be 
very hard and solid and difficult enough to divide into these two por- 
tions, so no efforts were made at further division or section, which 
would no doubt have been more satisfactory, if successful. 
The specimens are in the collection of Mr. G. T. Bethune-Baker.
