? A twig, terminating in a bud, with two branching
twigs growing from it, and a harmless nondescript fly or butterfly
perched on the back of it. The combination of a familiar sight and a
threatening sound would very plausibly result in cautious immobility. As
for its instantaneous assumption of the pose, to move instantaneously is
the next best thing to not moving at all. It is less likely to startle
than a slow movement. Twigs which have been bent get suddenly released
in the natural course of events; they do not move slowly. The
instantaneous appearance of a twig where no twig was before may possibly
give the victim pause; it may halt out of caution, not out of
terror.--[TRANS.]]

[Footnote 3: The word "butterfly" is here used, as is the French
_papillon_, as a general term for all Lepidoptera; the insect in
question is of course a moth.]

[Footnote 5: _Rabasso_ is the Provencal name for the truffle; hence a
truffle-hunter is known as a _rabassier_.]

one of the true tuberaceae, the _Tuber Requienii_, Tul., of the size of a
cherry.]

[Footnote 7: The difficulty in conceiving this theory lies in the fact
that the waves travel in straight lines. On the other hand, matter in a
state of degradation may expel particles highly energised and of
enormous velocity. Most antennae are covered with hairs of inconceivable
fineness; others may contain cavities of almost infinite minuteness. Is
it not thinkable that they are able to detect, in the gaseous
atmosphere, floating particles that are not gaseous? This would not
prevent the specialisation of antennae as mere feelers in some insects
and crustaceans. The difficulty of such a supposition lies in the
fact of discrimination; but if we did not possess a sense of taste or
smell discrimination would seem inconceivable in their case
also.--[TRANS.]]

[Footnote 8: This classification is now superseded; the Pea and Bean
Weevils--_Bruchus pisi_ and _Bruchus lenti_--are classed as Bruchidae, in
the series of Phytophaga. Most of the other weevils are classed as
Curculionidae, series Rhyncophora.--[TRANS.]]
