slightly to overlap. Anteriorly these plates form pro- 
jections round a deep cavity the general arrangement 
of which can best be understood from the figure. The 
head in the preserved example is pointed vertically down- 
wards, though this is probably not a natural position. 
The lateral parts of the segments form a kind of mantle 
which, when in close contact with the support, completely 
covers and protects the head, legs, and ventral surface. 
The last segment is prolonged into a bifid process. The 
larval cuticle is of comparatively enormous thickness 
and consists of a dense fibrous tissue carrying dorsally 
a number of small hooked spines. The surface of the 
cuticle, fig. 11, shows, under a medium magnification, a 
delicate tracery having a squamoid pattern, and fairly 
evenly distributed upon it are great numbers of chitinanths, 
resembling in shape single roses, in many cases bearing 
a partially or completely expanded chitinous tuft. As 
the tufts are easily broken it seems probable that normally 
they are always formed, and that where only the rose 
formation remains they have become detached. Length

Pupa. The pupa is shown, not quite complete at fig. 
5. It is difficult in a mere black-and-white sketch to sug- 
gest its extraordinary resemblance to a bud. The terminal 
segments are progressively tapered towards the point 
of attachment, and the long axis of the pupa forms a sinuous 
curve giving it a most characteristic shape. Judging from 
the appearance of the dry skin, the original colour is green, 
somewhat darker towards the point of attachment. The 
central portion of the dorsal surface is also darker, as are 
the wing-cases, thus giving the lateral parts a close resem- 
blance to the green part of the expanding bud. Length 
about 15mm. Farquharson, Moor Plantation. Jan.—leb.

Larva. Fig. 9 shows the larva with head and feet 
retracted. It is really rather similar to that of the previous 
species, but differs im the much simpler structure of the 
anterior segments. Farquharson describes the colour 
as “‘a sort of mistletoe-leaf green,” exactly resembling the 
immature flowers which are “dull green—a sort of bud- 
scale green shot with brownish hairs ” (pp. 368, 372). The
