calls the grasshopper, but which is very certainly Auabrus simplex. 

 He says: "These insects were first seen by me in Pitt river valley 

 during the Summer of 1859, a d in such numbers as actually to cover 

 the ground. 



The insect deposits the eggs by making perpendicular and oblique 

 holes in the ground, to the depth of an inch, by means of its tail, which 

 is shaped like a bayonet, and is hollow. The eggs are passed from the 

 ovary into this tail and are dropped one by one into the holes. 

 It appears to have no particular food, but feeds upon all kinds of vege- 

 tation ; it will eat the dead and crippled of its own kind, but I have 

 never observed them destroy one another. Immediately be- 



fore uniting sexually, the insect without the tail (which I presume to be 

 the male), utters a shrill whistling sound, as if to call his mate. The 

 sexual act lasts about one or two minutes, and the peculiarity I observed 

 at this union was, that the one I presume to be the female was over 

 the male, instead of the reverse. After the act a small bag evidently 

 the ovary is attached to the body of the female close to the tail ; this is 

 extracted from the other without the tail ; after a while the bag disap- 

 pears. * * * " 



These observations of Capt. Feilner, who was killed by the Indians 

 soon after making them, agree quite exactly with those of recent writers.
