legs are not put to the ground- but held straight out, the 

 tibiae and (arsi being at the same time agitated furiously 

 as if trying to grasp something. We have not observed 

 these in the open but it seems probable that they run 

 about in the grass and use their front legs to seize grass 

 stems. In our cages we have observed this peculiar me- 

 thod of locomotion when the insect was on the bottom 

 of the cage bu{ more often when it was trying to climb 

 up the sides rapidly. When progressing in this manner 

 they remind one of a small dog running on its hind 

 legs. 



When at rest, the attitude is no! always the same 

 but it is most often as follows, four hind legs well spread 

 out, femora sloping slightly upwards from coxae, tibiae 

 nearly vertical or sloping outward. Abdomen and thorax 

 making aboul ecpiai angles with vertical, angle between 

 them variable but about a right angle, sometimes less, 

 sometimes more. Coxae of front legs not brought close 

 up to thorax but coxa, femur and tibia in contact and 

 brought up to "chin" so that head and front legs appear 

 as one huge head. Hack of head and mitre continue line 

 of thorax. (>oxae frequently pushed out perpendicular 

 to thorax, femora and tibiae still remaining closed. 

 When about to attack, thorax thrown back to vertical 

 position, abdonien nearly horizontal. 



This description is equally applicable when the in- 

 sect is on the sides or top of the box if for "vertical" we 

 substitute "perpendicular to plane on which the tarsi 

 rest". 



The favourite position is at one of the upper edges 

 of the box. 



When eating they frequently fall to the bottom of
