VARIATION OF AGLAIS URTIC.E.

 specimens. Of the 24 previously-named forms, the following, at any 

 rate, I know to occur m Britain — atrebatensis, caendapicata, conne.ra, 

 discolor, ic/inusa, ichnusoides, nigra, polarix and salmonicolor, and of the 

 others nixa, pyijwaea and urticoides have almost certainly occurred.
