LABIDURA. 97 



This is one of the group of smaller species, including L. lividipes 

 and L. temiicomis. It is well characterized by the fattened and 

 dilated forceps, resembling many species of Forjicula. 



It is interesting to note that two species very similar to this 

 occur preserved in Baltic amber of Oligocene age.
