 and defends her progeny while life endures. It hides under stones^ 

 logs, etc."

I have seen too few specimens of this form to be able to determine 

 satisfactorily the validity of its rank as a variety. It is maintained 

 here as such tentatively. Females showing the variant colors are not 

 known to me personally, nor have such been reported.
