Gryllus Tettigonia, agrees with the preceding family in the great 

 length and slenderness of the antennae, the exserted ovipositor of the fe- 

 males (Jiff- 55. 1. Meconema varia ? ), and the talc-like spot at the base 

 of the wing-covers of the males. It is, however, distinguished by having 

 the wings and wing-covers disposed, when at rest, like a slanting roof; 

 the tarsi also are 4-jointed. The mandibles are less strongly toothed 

 than those of the Achetidse ; and the ovipositor is generally compressed 

 and sabre-shaped. 



The body of these insects is far less robust than that of the true 

 locusts, the legs and antennae being very long and slender, the 

 wings very large and delicate, and the wing-covers often extending 

 far beyond the extremity of the abdomen, which is liable to shrink 

 on being dried, so that it is serviceable to introduce cotton into the in- 

 terior, to prevent this from taking place. The head (Jig. 55. 2. head of
