anatomy of the mole-cricket, 
ments which so peculiarly characterize the mole-cricket. 
Compared indeed with' the other legs, and with the general 
size of the animal, they are as if the brawny hand and arm 
of a robust dwarf were set on the body of a delicate infant ; 
and the indications of strength which their structure mani- 
fests, fully answer to their extraordinary size : but I shall 
describe them more particularly hereafter, and proceed now 
to the . description of the abdomen. 
The abdomen.^ In its general form and structure this 
part resembles the corresponding part of the hornet : but it 
consists of more segments, and is much less bright in colour. 
There are twelve segments in the abdomen of the gryllo- 
talpa, of which the nearest to the thorax carries the upper 
pair of wings on its upper part, and the middle pair of legs 
on its lower part ; the next segment carries the under pair 
of wings on its upper part, and the hind pair of legs on its 
under part. These two segments which are usually de- 
scribed in entomological systems as belonging to the thorax, 
are of a horny consistence and very hard on their upper 
side ; while all the rest are merely membranous ; they are 
also covered with much long and rough hair, while all the 
rest, excepting the last but one, are sparingly covered with 
short hairs. The last segment but one is furnished on each 
side of its upper surface with a row of red hairs or bristles, 
which are curved inwards in a direction towards each other ; 
obviously for the purpose of preventing the folded extremi- 
ties of the under wings from falling off the back on either 
side. 
The under surfaces of all the segments are of a thicker
