 stance of the Aphis horcalis having been found on floating 

 floes of ice in the Polar Sea, at one hundred miles distance

 near resemblance to the Aphis Piece, which feeds on the silver 

 fir {Pinus Picca, L), whence it derives its name, would in- 

 duce the belief that the floating trees of fir, that are to be 

 found so abundantly on the shores and to the northward of 

 Spitzbergen, might possibly be the means by which this 

 insect has been transported to the northern regions. It was 

 never seen on the wing, and the few specimens that were 

 obtained were in a very languid state, but revived by the 

 heat of the hand."
