п. А CATALOGUE OF THE INSECTS 



OF NORTH-EAST GREENLAND WITH DESCRIPTIONS 



OF SOME LARVÆ. 



I. с NIELSEN. 



The insects brought home by the "Danmark" Expedition 

 were collected by the zoologist of the expedition, Fritz Johansen, 

 in the neighbourhood of the place where the ship was located, 76° 46' 

 N. L., 18= 14' W. L. 



The insect fauna at this spot has in the main the same character 

 as in the more southerly parts of East Greenland which have been 

 investigated by earlier expeditions, but the number of species is 

 somewhat smaller in consequence of the more northerly situation 

 of the regions investigated. Nervertheless, the insect fauna shows 

 a few striking characteristics, e. g. the complete absence of represen- 

 tatives of the order of beetles. I have formerly ^ remarked upon the 

 sparse representation of this order also in other parts of East Green- 

 land in comparison with West Greenland; this condition reaches its 

 culmination in North-East Greenland where not a single beetle was 

 obtained, in spite of the fact that not a few collections obviously 

 were made at places which the beetle fauna frequents, under stones 

 and plants, and in the water. 



No species of Pseudoneiiroptera or Orthoptera have yet been 

 brought from East Greenland, though representatives of these orders 

 are found on the west coast (the representative of the latter order, 

 a Blatta, was however possibly introduced). 



Similarly, no Physopods occur in the collections; the zoological 

 journal, however, mentions a spring-tail not brought home, and of 

 this family several species are known further south on the east coast. 



Haematopinus tricliechi, not previously found on the walrus of 

 East Greenland, has now been met with here, so that the order of 

 Siphanculata is also represented in this part of Greenland.
