 it is heretofore only found in a few places on miry, marshy ground, at 

 the rim of water holes, and woodland waters under leaves and at plant- 

 roots (SkBTY-ping Forest and Lundby Hills at Aalborg; at F/>nstrup ^ams, and 

 in St. Dyrehave at Hillerjid, especielly in the spring, author).- Teneral 

 specimens with brownish abdominal tip occur; they resemble thereby a close- 

 ly allied species, rupicola Pye, which is found in England.
