Anmerkung zu Amalopteryos Eaton von G. H. Verrall, 

 Observations on the Insects collected in Kcrguelen Islands 1879: 



It inay be mentioned, tliat the only known species of the nearest 

 allied British genus Hecamede has somewhat similar habits, 

 beeing found on fresh marine rejectamenta and but seldom attemp- 

 ting to fly. Ämalopteryx ist apparently less strictly conhned 

 to the shore, being commonest among the grass bordering the 

 beach and among the birds nests in the cliffs.
