The Lepidoptera number 39 species in Greenland, of which 

 14 are common to both coasts, 22 only in the West- and 3 

 in East-Greenland. The Ehopalocera appear to be more common 

 in the East, for besides the two common species, Colzas hecla 

 and Argynnis chariclea var. arctica, two others occur, Argynnis 

 polaris, and Lycœna orbitulus var. aquilo, which appear to be 

 rather common, whilst they have only been found a few times 

 in West-Greenland on the northernmost part of the coast line. 

 The Heterocera on the contrary, are much better represented 

 in the West than the East, but as several of the species, for 

 example of the two genera Agrotis and Plusia, are exceedingly 

 rare and in most cases are only represented by single old 

 specimens, collected over a period of many years, it is pos- 

 sible that they have escaped the attention of the collectors on 

 the East coast. 



Of the Neuroptera, 7 species are found in West-Greenland, 

 of which only one species Apatania arctica also occurs in the 

 East, while Pseudo-neuroptera and Orthoptera are only repre- 

 sented in the West. Of the Orthoptera, only the larva of a 

 Blatta has been found on the West coast. 



The Remiptera in West-Greenland reach the total of 12 

 species (4 Homoptera and 8 Heteroptera), of the first Group 

 only one specimen has been found in East-Greenland, and of 

 the second Group, two. 



Of the Mallophaga 40 species have been found, of which 

 only 6 are common to both coasts, but as the birds that are 

 hosts for these parasitic forms are, for the most part, widly 

 distributed in both East- and West-Greenland, it is most pro- 

 bable that the number of species common to both parts will 

 be greatly increased when more material is forthcoming. 



Of the Fhysopoda the common European species Physopus 

 vulgatissimus, is in all probability found commonly both in the 

 East and West.
