usually smaller size, the sparser puncturing of the head, pro- 

 thorax and elytra, and by the structure of the seventh ab- 

 dominal segment of the male, which is produced beneath on 

 each side info a small acute spine. 



In marshes amongst vegetable debris, at the roots of grass, 

 and hybernating beneath loose bark of willows. I have met 

 with it in the months of October and April near Highgate, 

 and in the vicinity of Croydon. Apparently \evy rare.

 Mr. Waterhouse, not having had an opportunity of care- 

 fully comparing Dr. Power's specimen with a single example 

 of an insect, which he, Mr. Waterhouse, referred to the A. 

 rubiginosa, Schmidt, Eric, considered it identical therewith. 

 A subsequent comparison of the two specimens has convinced 

 him that they are both referrible to the A. nigrita. A. 

 rubiginosa is, therefore, to be cancelled from the Catalogue 

 of indigenous species, and A. nigrita inserted in its place.
