1907- Bhresford. — Araneida of Lambay. 65 



ATTIDiJE. 



Heliophanus cupreus (Walck.) — One adult male and a number of 

 adult and immature females taken by Mr. Halbert in June. 



Attus pubescens, Fab. — One adult female and one immature taken 

 in June by Mr. Halbert. This is the first Irish record of this spider, 

 which M. Simon says is common all over Europe. In England it is, 

 Mr. Cambridge says, rare at Bloxworth, but plentiful at one or two 

 places in Hampshire, and has been found in other parts of England. 



ACARINA. 



BY J. N. HALBERT. 



During a visit to Lambay in October last I collected a large 

 number of mites, a group of animals which, with the exception 

 of the family Hydrachnidae, are well represented on the island. 

 Those of the family Oribatidae or " Beetle-mites/' have been 

 identified with the assistance of Dr. Michael's fine monogiaph 

 on the British species. 1 Of the twenty-two species of these 

 mites collected, the most interesting is Hermannia carinata, a 

 species first described from Greenland. At the time of the 

 publication of the part of the ' k Tierreich/' dealing with the 

 Oribatidae, it had not been recorded from any other locality, 

 and 1 cannot find that it has since been found in the Britannic 

 area. The remaining species are widely distributed. 



This appears to be the first list of Irish Oribatidae that has been 

 published, and all the species here recorded are new to this 

 country. The nomenclature used is that of the " Tierreich " 

 Oribatidae, A. D. Michael (Berlin, 1898). 



The nests of the small yellow ant (lasius flavus), an extremely 

 abundant insect on the island, are tenanted by two kinds of 

 myrmecophilous mites belonging to the family Uropodidae. One 

 of these is apparently an undescribed species.
