16 THE entomologist's RECORD. 



probable that my specimen was bred from one of the many specief< of 

 diptera which inhabit this nest, some of which are abundant. 



Aphid.e. — Paracletes cimiciformis, C. Heyd. — This species was 

 taken in some numbers in nests of Tetiattmrium raespitniti, the other 

 side of Rarae Head, in April. This is the " Myrmecophilous aphis " 

 par e.rcellenre, it is much more active than the others found with ants. 

 When the nest is disturbed the plant-lice themselves hurry down into 

 the chambers, as well as being carried by the ants. Evans found it with 

 LaaittH fiavHs at Queen's Ferry {Ann. Scot. Nat. Hist., 1906, p. i^41), and 

 Newstead with the same ant at Loggerheads (/v»^ Mo. Mat/., 189B, p. 

 115), but the principal host is 'ietrauiorinni caeH/iitinii (see Schonteden, 

 " Les Aphides Radicicoles de Belgique et les Fourmis," Aiui. Soc. Kitt. 

 Bel;/., xlvi., 1902, p. 138). I have taken a number of other specimens 

 of Aphidae in ants' nests, which have not yet been determined. 



CocciD.E. — RiPERsiA suBTERRANEA, Newst. — This species occurred in 

 numbers in nests of l^asiits }ii;/ef and Tetramoriiiiii caea/iitiiin at Whitsand 

 Bay, in April. This species has now occurred at Ingoldisthorpe (New- 

 stead), North Queen's Ferry (Evans), Dartmouth and Whitsand Bay 

 (Donisthorpe). According to Newstead it has not been recorded from 

 any other part of the world. I must thank my friend Mr. Ernest 

 Green for kindly naming these specimens.
