110 MR. H. 8. LEIGH ON THE [Feb. 2, 
laminated expansions are generally pale green on the dorsal and 
rich emerald-green on the ventral side. The colour, however, 
varies considerably in different individuals, some being darker 
green than others, and I have seen one or two quite yellow 
specimens. The legs with the exception of the prothoracic 
femora are entirely brown, and being prettily decorated with 
many shades of yellow look rather like small pieces of decaying 
leaves. ‘The expansions of the prothoracic femora are of a green 
and brown colour; they are elegant in shape and, compared with 
those of the female, are very small. 
The females are mucb larger and more unwieldy creatures 
than the males. They attain a length of from 95 to 100 mm. 
The head is large; not quite so quadrangular as in the male and 
is devoid of the red ocelli. The eyes are much less prominent 
than in the male,and the antenne are very short, being composed 
of only nine segments. 
The prothorax takes the form of a shield with a slight furrow 
in the centre. The mesothorax becomes much broader than 
the prothorax and bears the remarkable leaf-like tegmina. The 
latter, which generally remain in a state of repose, are of a most 
remarkable structure and remind one of leaves to their minutest 
detail. They are large and ample, being 54 mm. in length, and 
generally cover the greater part of the abdomen. Each tegmen 
is similar to half a leaf and has on its internal side a large 
nervure from which at intervals smaller nervures emanate ; 
these in turn eiving off subordinate veins which form a complete 
ramification throughout the whole structure. The leaf-like: 
form of the tegmina is carried still further since they are 
adorned with many irregular rust-coloured markings similar to: 
those often found on leaves. 
The metathorax is broader than the mesothorax and attains. 
at its posterior end a breadth of 18 mm. The hind wings, which 
are so conspicuous in the male, are represented in the female by 
two very small processes, covered by the tegmina and entirely 
hidden from view. 
As in the male, the first three abdominal segments become: 
broader in regular sequence until the maximum width of about 
44 mm. is reached in the fourth abdominal segment; from this. 
there is a gradual tapering of the segments to the posterior end 
which terminates in a bifid protuberance. The abdomen of the 
female, although possessing flat expansions of considerable size, 
is very bulky compared with that of the male, and even increases. 
in volume as the ova mature. The general colour of the abdomen 
is green of varying tints, and it is almost impossible to describe 
one colour as applicable to all or even to many individuals. 
Perhaps pale leafy-green is the commonest colour of the dorsal 
side whilst the ventral is rich emerald-green. St. Quintin says. 
he has “bred some entirely yellow and several of a crushed- 
strawberry colour, while a few were of an amber-brown.” 
Similar spots to those which were found on each side of the
