WALKING LEAF-INSECTS 
Bhati-ves of the East Indies, and remarkable for thetr resemblance to 
green leaves 
incurved at the extremity. There are two 
varieties, in one of which the 'forceps is 
twice as long 'as in the other; but inter- 
mediate gradations do not seem to be met 
with. In the female the forceps is narrow, 
nearly straight, and approximating. The^ 
earwig is a nocturnal insect, and hides itself 
during the day in large-headed flowers, like 
dahlias, to which it is very destructive, or 
in any convenient dark and narrow crevice, 
especially among decaying vegetable matter. 
It derives its name from its occasionally 
entering the human ear, but it may be 
easily driven out by dropping in a little olive 
oil. In most books it is denied that earwigs 
enter the ear at all, but it is, nevertheless,' 
an undoubted fact ; and the fanciful deriva-- 
tion that has been suggested of eariving in 
the place of earwig cannot be entertained 
respecting an insect which seldom shows its’ 
wings at all. It should be noted that the* 
female earwig is said to tend her young 
very much as a hen tends her chickens- — -an 
uncommon habit in insects. 
The Common Cockroach is too well 
known to need description. The individuals 
with half-developed wings are the perfect 
females ; but there are other species in which 
the wings are fully developed in both sexes,' 
others in which the male is winged and 
the female wingless, and others again in 
which both sexes are wingless. In warm 
countries and on ship-board cockroaches are 
far more troublesome than in cold climes ; 
and the large brown ones, with a mark on 
the back of the thorax resembling a crown, 
and very broad wing-cases and wings, are 
called Drummers in the West Indies, from 
the loud noise they keep up during the 
night. 
Lady Burton has given an amusing 
account of her introduction to cockroaches 
abroad: “After two days we were given a 
very pleasant suite of rooms — bedroom, 
dining- and drawing-room — with wide win- 
dows overlooking the Tagus and a great part 
of Lisbon. These quarters were, however, 
not without drawbacks, for here occurred an 
incident which gave me a foretaste of the 
sort of thing I was to expect in Brazil. 
Our bedroom was a large whitewashed place ; 
there were three holes in the wall, one at
