These statistics seem, on the whole, to prove decisively that 
the west coast furnishes a better collecting ground than is 
the case with the north and east. One reason for my 
success at Dyrafjord, on the west coast, was that I landed 
there in the evening, when multitudinous geometride were on 
the wing at the approach of dusk. The most abundant 
tribe in Iceland, and consequently, the large proportion of 
moths above indicated consists of geometrid, and next to 
these the noctuee.
