the female common cricket •,Jig. 54. 2 — 13., details of this species), and 

 is distinguished by the great length and slenderness of the antennae 

 {Jig. 54. 6., base of antennae), which often exceed that of the entire 

 body ; the horizontal position of the wings and wing-covers when at 

 rest, the former being of large size, and, when folded up, forming a 

 pair of long and slender filaments, often extending far beyond the ex- 

 tremity of the body {Jig. 54. i. bb.), and the latter being, in the 

 males, furnished at the base with a large talc-like spot ; the body 

 is robust, but depressed above ; the eyes large and round ; the 

 ocelli* two, in some species; the jaws strong, with several acute 

 transverse teeth {Jg. 54. 3.) ; the maxillas slender, with two acute 

 terminal teeth ; the outer lobe (galea) is concave at the tip (for the

* There are two very distinct ocelli in both sexes of the mole cricket ; in the 

 male field cricket there are two yellow spots behind the base of the antenna, and 

 a small transverse one between the eyes. In the male of the domestic cricket there 

 are three very indistinct ocelli, which are entirely obsolete in the females.
