188 EIPERS1A TOML1NII. 



the only known habitat for this species in Great 

 Britain. 



Distribution. Common at Moulin Huet, Guernsey, 

 where it was first discovered by Miss Tomlin on grass 

 roots in an ant's nest, September, 1891. Mr. W. A. 

 Luff, who has taken much interest in this species, 

 informs me that it is not uncommon there, and that it 

 is associated with Tetramorium csespitum. He has also 

 found the coccid at Alderney, but in that locality it 

 was associated with Lasius alienus, and Mr. Luff 

 " particularly noted that the coccids were found only 

 under stones covering ants' nests, and in many 

 instances were some distance down the holes leading to 

 the interior of the nest. When I loosened a coccid 

 from the grass root to which it was attached the ants 

 carried it off into the interior of the nest ; and in two 

 instances I saw several ants loosen a coccid themselves 

 and carry it away. Even portions of the sac which I 

 had broken off would be eagerly seized on and carried 

 off."
