64 COLEOPTERA. 



Aleochara inquilina, Maerkel in Germar, Zeitschr. f. d. 

 Entom. v. 69 (1844). 

 Two examples were exhibited at a recent meeting of the 

 Entomological Society by Mr. Waterhouse in behalf of their 

 captor, Dr. Power, who obtained them during the current 

 year, one from a nest, of Formica fuliginosa, the other from 

 a nest of Formica rufa ; a circumstance totally at variance 

 with the observations of our continental brethren, who accord 

 this species to F. fuliginosa exclusively, its near ally, Thias. 

 angulata, to F. rufa, and which renders it desirable that a 

 very careful examination should be bestowed upon these 

 specimens.
