of great rarity which rich men keep alive in cages in order to secure 
its eggs, which they set in rings like jewels, and consider to be a 
most powerful charm against evil spirits of all kinds. These eggs 
are said to be of a beautiful red colour. 
Remarks.—Professor Poulton has been kind enough to show me 
some young larve of Hymeropus bicornis that he has lately received 
from Mr. Shelford, Curator of the Sarawak Museum, Borneo, 
together with some Heteroptera to which they bear a very close 
and detailed resemblance. It is indeed remarkable that any animal 
should be so highly specialized in two different directions of 
deception during the lifetime of an individual. The imago of 
this form, judging solely from dried specimens, may possibly show 
a likeness in lite to a withered flower. Its long white tegmina, 
with their faint brown markings, may well have this appearance 
in life, if they are possessed of the flower-like glistening which 
distinguishes certain parts of the body of the pupa. 
The pupa of the Indian Mantis, Gongylus gong ylides ', the habits 
of which have been described by Dr. J. Anderson, resembles the 
AKanchong in swaying its body while waiting for prey, but differs 
from it in that only the lower surface is coloured like a flower, 
the back being green, and that the flower-like shape is brought 
about by the expansion of the thorax. Two varieties of the 
pupa of Hymenopus itself are known: the one is pink, the other 
white. Any information as to whether these are seasonal forms, 
whether they confine themselves to the flowers which they resemble, 
and whether they are in any way modified by light reflected from 
their environment, would be of the very greatest interest. Wood- 
Mason reports * two specimens, the one white and the other pink, 
taken at an interval of six months, apparently from the same 
district, in Assam. Mr. R. L. Butler of Selangor tells me that he 
has taken white specimens, and white specimens only, on the 
verandah of a bungalow at Kuala Lumpur, on which white lilies 
were growing in pots. Wallace* says that in India the pink 
variety will settle among any flowers or leaves, and he seems to 
lay stress on this point in a note which I have received from him. 
In the figure* of this insect given in Poulton’s ‘Colours of 
Animals ’ (p. 74) it is represented as sitting head downwards, on 
a leaf, with the abdomen and thorax in a straight line ; in all of 
which points the attitude of the specimen depicted differs from 
that of mine, though the first is of no great importance. The 
brown lines on the dorsal surface of the insect °, and the dark spot 
at the tip of the abdomen, are entirely omitted by the Indian artist. 
My specimen certainly refused to sit among leaves when it was in

* The figure is from a native drawing sent to Wallace by Wood-Mason. from 
whom the information about this insect in ‘ Darwinism ’ was also obtained. 
® These lines, and also the black tip to the abdomen, are just as conspicuous, 
judging from dried specimens, in individuals from other parts of the East as 
they were in the one observed at Aring.
