PITHOEA. 201 



as well as with the lesser ovate Dytiscus, 

 shaded with grey, and known by its blunt 

 cloven sternum. (D. cinereus.) On the 

 beach multitudes of black insects without 

 wings, and half covered with shelly cases, 

 were running about. (Probably Cimex lit- 

 toralis.) There were also abundance of 

 Ephemerce (May-flies), all which had two 

 prominent fore feet, and three bristles at 

 the tail. I caught several, thus render- 

 ing their transient existence still shorter. 

 They were of two species, one larger, of a 

 blackish hue, with dark clouded wings 

 (E. vidgata) ; the other about half as large, 

 with a blackish thorax, and white wings. 

 (This does not agree with any species in 

 the Fauna Suecica.) 



Not far from the shore, on a small eleva- 

 tion, where the trees and underwood had 

 lately been burnt down, grew the Straw- 

 berry-leaved Bramble (Rubus arcticus) 

 with jagged petals, a remarkable and ele- 

 gant variety. (See Fl. Lapp. t. ö.f. 2.)
