 house, Proc. Ent. Soc. Lond., 4- Aug. 1856, Zool.

 Found by Mr. Waterhouse near Brockenhurst, and sub- 

 sequently by myself near Croydon in company with Formica 

 fuliginosa.

d. Insect. Deutsch. ii. 184, 34 (1856). Aleochara 

 hcemorrkoa, Sahib., Ins. Fenn. i. 355, 20 (1834). 

 I have repeatedly met with this insect in nests of Formica 



rvfa at Hampstead and Highgate ; Mr. Waterhouse has 



found it with the same ant near Erith. 



16. Oxypoda formiceticola, Maerkel in Germar, Zeitschr. 



f. d. Entom. iii. 213, 10 (1841) ; Kraatz, Naturgesch. 

 d. Insect. Deutschl. ii. 182, 32 (1856). 

 I have found this species, but very sparingly, in nests of 

 Formica rufa, both at Hampstead and Highgate; Mr. 

 Waterhouse has taken it with this ant near Erith. 



Genvs THIASOPHILA, Kraatz, Naturgesch. d. 

 Insect. Deutschl. ii. 69 (1856). 

 The insects comprised in this genus differ from the Aleo- 

 charce, with which they had until recently been associated, 

 in having the maxillary palpi 4-jointed, the labial palpi 

 3-jointed, the ligula more elongate and more deeply cleft, 

 the thorax uneven, its posterior margin waved and its hinder 

 angles nearly rectangular. Both species appear to be ex- 

 clusively confined to ants' nests, viz. one to those of Formica 

 rafa, the other to those of Formica fuliginosa; the first 

 only has been detected in Britain.
