Specimens absolutely identical with those from Eu- igl 



rope have been collected from the indicated localities. ^ 



It is quite likely that some of the specimens reported 

 by collectors under the name of kumilis or desidiosa 

 may have belonged to this species. The form called 

 ferruginea by Haldeman seems to differ only by 

 having the pillar lip more closely appressed, a character which any 

 large series will show to be inconstant in individuals among them- 

 selves as well as in the same individual in different stages.
