left in its complete form, except in not being furnifhed 
with wings. 
This creature is very rarely met with in collections in 
its complete or winged form ; being generally feen in 
the lefs advanced growth before-mentioned, in which 
the rudiments of the wings are but juft vifible. In 
that imperfect ftate it has commonly been defcribed 
under the title of the walking ftick. 
A molt lingular circumftance in this infeft, (and 
which takes place in but very few others of the genus) 
is, that, exclulive of the elytra, or wing cafes, there is 
an additional pair, which may be fuppofed to ferveas 
a farther guard in fecuring the wings themfelves: this 
fecondary pair however leem to be connate with the 
wings themfelves, fo as to make a part ot them. 
This moil curious and uncommon infeft is a native 
of the Ifland of Amboyna, and the fpecimen from 
which the figure was taken, is now in the higheft pre- 
fervation in the Leverian Mufeum.
