Summary. 



I. Brychins elcvatus, a complex of forms. 



The author gives a minute characteristic of the variabih'ty of his two 

 captures of Bryclnus, viz. in Karasjok, Finmarken (69^ 27'), and in the 

 neighbourhood of Dal near Kristiania, the first chiefly Br. cristatus with 

 rossicus and transitions to norvegicus, the second chiefly noj'vegicus (descrip- 

 tion in Latin), an intermediate form between the Middle-European elevatus 

 and rossicus. All the European forms, with the exception of glabratus, 

 are closely allied and solely forms of the highly variable Br. elevatus, the 

 keels on the third insterstice on elytra being more pronounced the farther 

 north we proceed. 



II. The Norwegian species of Haliplus. 



The author gives a table of the species of the genus, and a charac- 

 teristic of the different species with description (in Latin) of a new Arctic 

 form of //. fiilvus {Sparre-schucideri n. var.).
