The Migratory Locusts or Acrydii of Latreille and 

 tlieir allies are orthoptera which have a large head, short 

 antennae, and three-jointed tarsi, instead of four-jointed, 

 as in the Locustidse ; and they have no projecting ovipo- 

 sitor. The celebrated Migratory Locusts (Acrydium), the 

 Red-legged Locusts (Ccdoptemis), and the Coral-winged,

 the anterior pair being generally the smaller ; very large 

 eyes and large mandibles; and they are destitute of 

 weapons except their jaws. Most of the Neuropters live 

 in the water during the larva and pupa state, and many 

 species* do not undergo a complete metamorphosis. 



The White Ants or Termitidae, inhabit only warm 

 countries, and in the larva state feed upon wood, devour-

 have done in the Isle of France. The Stone-flies or 

 Perlidae (Fig. 456), have many-jointed antennae, and the
