This division includes in it the Cocla-oaches, Crickets, Grass- 

 hoppers, and Locusts, and those singular-looking creatures, 

 from tropical countries, which have been, by common consent, 

 named "walking-sticks" and "leaf insects." Some of the 

 latter, which we see in our museums, have the wing-covers of 

 so bright and fresh a green, that we can with difficulty per- 

 suade ourselves we are looking on an insect; while others 

 present a no less striking resemblance to the colour of the 

 leaf, and its delicate reticulations, as it lies on the ground in 

 its withered state {Fig. 94). 



Another foreign insect deserves mention, because it has 



* Derived from two Greek words; one si^ifying straight, the other 

 a wing; the arms being longitudinally folded when at rest. About fifty 



Irish species.
