and Ireland, and has a well-nigh cosmopolitan range abroad, inhabiting, for 

 example, Greenland, Siberia, South America, and Sumatra. 



A. longispinus Tullberg. 



Portnakilly, a few on herbage near the beach (July, 1911). 



This species, nearly allied to the last, is found both in the east and west 



of Ireland, as well as in Scotland and northern England. It seems to be a 



characteristically Arctic insect, inabiting Novaya Zemlya, Spitsbergen, Franz 



Josef Land, and Lapland, and appearing also, like other members of this order, 



in South America. 



A. viaticus (Linn.) Tullberg. 



A. murorum Lubbock (Monograph, 1873). 



In soil of hotel garden, numerous (R. Welch, June, 1910) ; Strake, in 

 newly manured soil, many (July, 1911). 



This is another very widespread insect, probably distributed throughout 

 the British Islands, and ranging from Greenland and Spitsbergen to Tierra 

 del Fuego at the far extremity of South America, and to Macquarie Island in 

 the Antarctic Ocean south of New Zealand. 



Xenylla maritima Tullberg. 



Kinnacorra, on beach, a few (July, 1911). 



This species is known both in the east and west of Ireland, as well as in 



Scotland, England, and Jersey. Abroad it ranges in Europe from Norway 



and Finland to France, and is recorded also from North America. Neither 



in the British Islands nor on the Continent is it confined to the sea-margin, 



being found at inland localities under the bark of trees, as well as in moss 



and garden-soil. 



Anurida maritima (Guerin). 



Common around the shore in rock-crevices between tide-marks (R. Southern 

 and R. Welch, June, 1910) ; numerous on the surface of south-eastern rock- 

 pools (July, 1911). 



This well-known little insect is found on the southern, eastern, and 

 western coasts of Ireland and Great Britain, and has been recorded from the 

 shores of eastern North America, Scandinavia, Heligoland, and France. 



ENTOMOBRYIDAE. 



Folsomia quadrioculata (Tullberg). 



In moss, several (August, 1911, J. N. Halbert). 



This is an interesting addition to the Irish fauna, and thus far it has not 

 been recognized on our mainland. Lately introduced to the English lists by 

 Bagnall (1910) and Collinge and Shoebotham (1910) ; it is widely spread
