xcviii Appendix. 



they are the work of more than one genus of Sericostomatidfe. The European 

 forms have not been referred to any particuhxr insects ; and in Eurojje no 

 insect has been discovered that absolutely agrees generically with that bred in 

 America. The same remark applies to those from New Zealand ; and T have 

 a suspicion that they may be the work of species of Fycnocentria. It is much 

 to be desired that colonial entomologists will investigate this matter ; the cases 

 are probably found attached to stones in streams.
