IX. — The Regeneration of Limbs in the Mantid^, and the 

 constant Occurrence of a Tetramerous Tarsus in Limbs 

 regenerated after Self- mutilation among the Orthoptera 

 pentamera *. By Edmond Bordage. 



Numerous experiments which I have made upon the Phas- 

 mida3, and which I have described in * Comptes E-endus,' and 

 beibre the Soci^t^ de Biologic, have shown that among these 

 insects a limb regenerated atter self-mutilation constantly 

 presents a tetramerous tarsus instead of a normal one with 

 five joints. Messrs. Bateson and Brindley have made the 

 same observation so far as the Blattid^ are concerned. It 

 only therefore remains to be seen whether the same effect is 

 produced in the third and last family of the Orthoptera 

 pentameraj the Mantidse. 



1. I undertook the following researches in the island of 

 Bourbon upon the two species of Mantis of the Mascarenes 

 (^Mantis prasina and M. pustulata) which are easy to rear iu 

 captivity. 



In the case of the first pair of limbs {predatory legs) self- 

 mutilation never takes place. The same does not hold good, 

 however, in the two succeeding pairs. The leg becomes 

 detached from the body at the groove which marks the 

 trochantero-femoral articulation. Separation takes place with 

 the utmost facility. The process of regeneration in the laivte 

 goes on with marvellous rapidity, more quickly even than
