rendering the legs of this insect thick and deformed, and giving 
to its whole body a very singular appearance.” 
What instincts! what habits! Under this borrowed costume, 
under this cloak, which is no part of itself, the insect, as it were 
masked, has become twice its real size. What becomes of its dis-

other bugs; but generally its walk is slow, and it moves with 
measured steps. After having taken one step forward, it stops 
awhile, and then takes another, leaving, at each movement, the 
opposite leg in repose ; it goes on thus continually, step after step 
in succession, which gives it the appearance of walking as if by 
jerks, and in measure. It makes almost the same sort of move- 
ment with its antenns, which it moves also at intervals and by 
jerks. All these movements have a more singular appearance than 
it is possible for us to describe.’’*

about it. With the exception of the hemelytra and wings, which
