they are the work of more than one genus of Sericostomatidw. The European 
forms have not been referred to any particular insects; and in Europe no 
insect has been discovered that absolutely agrees generically with that bred in 
America. The same remark applies to those from New Zealand ; and I have 
a suspicion that they may be the work of species of Pyenocentria. It is much 
to be desired that colonial entomologists will investigate this matter ; the cases 
are probably found attached to stones in streams.
