226 On the Geographical Distribution of Insects. 



their representatives, except the Orthoptera and the Hemip- 

 tera. In Melville Island (75° North Latitude), besides these 

 two orders, the Coleoptera and Neuroptera are wanting. These 

 statements are perhaps premature, at least in relation to the 

 Hemiptera, for the insect which has hitherto been found near- 

 est the pole is an Aphis, met with on the ice about 82° 26' 

 44", nearly 33 leagnies from the nearest land, during Captain 

 Parry's Polar Expedition. It had no doubt been carried by 

 the wind from some point of the coast of Greenland, situated 

 to the south of that high latitude. 



Among the Coleoptera, the Carabidse are dominant in this 

 region, as might be expected ; in the order Lepidoptera, the 

 genera Colias, Argynnis, and Satyrus appear the richest in spe- 

 cies. The Orthoptera are reduced to a few Grylh;s, Acri- 

 dium, and Blatta ; the Hemiptera, which are more numer- 

 ous, are composed, for the greater part, of Cimicides, to which 

 may be added a small number of Cicadidse, Hydrocoryses, 

 and Aphides. Among the Hymenoptera the Ichneumonides 

 constitute the majority, as they do everywhere, and, after them, 

 the solitary Apidae. Finally, the Culicides and the Syrplii- 

 des appear to be most numerous among the Diptera. The 

 greater pai't of the species are common to the two continents, 

 and some of them ai'e found in the high mountains of Europe, 

 such as Colias Palaeno, which is common in Lapland and Ice- 

 land, and which Captain Scoresby has found on the coast of 

 Greenland along with Argynnis Dia. The others have almost 

 all the %K<ca.Q fades, as those of our climates. Finally, this re- 

 gion has a vei'y small number of species which are peculiar to 

 it. It is, therefore, properly characterized, less by the spe- 

 cialty of its entomological productions, than by the smallness 

 of their number. 



2. Begions peculiar to the Old Continent. 



2dly, The European Begion, bounded on the west by the 

 Atlantic Ocean ; on the east by the Oural Mountains ; on the 

 north, by the Arctic Circle ; and on the south by a line nearly 

 parallel with the 46° N. Lat. Notwithstanding its extent, this 

 vast territory has an entomology of a singulai-ly uniform cha- 

 racter. The same families predominate throughout, and the
