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

 constant Occuri'ence of a Tetramerous Tarsus in Limbs 

 regenerated after Self- mutilation among the Orthoptera 

 pentamera *. Qy Edmond Bordage. 



Numerous experiments which I have made upon the Phas- 

 mid^e, and which I have described in ' Comptes Rendus,' and 

 before the Societe de Biologic, have shown that among these 

 insects a limb regenerated alter self-mutilation constantly 

 presents a tetramerous tarsus instead of a normal one with 

 live joints. Messrs. Bateson and Brindley have made the 

 same observation so far as the Biattidas are concerned. It 

 only therefore remains to be seen whether the same etFect is 

 produced in the third and last family of the Orthoptera 

 pentamera, the Mantida3. 



I. 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 in 

 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 tiie 

 trochantero-femoral articulation. Separation takes place with 

 the utmost facility. The process of regeneration in tiie larvae 

 gues on with marvellous rapidity, more quickly even than
