long, with a scarcely visible fovea in front of the base in 

 the middle, very finely punctured. The elytra are a little 

 longer than the thorax, thickly and finely punctured. 

 The abdomen is black and shining, yellowish at the ex- 

 tremity, the basal segments finely and indistinctly punc- 

 tured, but with the pubescence pretty distinct, apical 

 segments impunctate. Legs yellow. 



In the male, the seventh segment of the abdomen has 

 the hind margin of both the upper and under plates 

 rather more produced and rounded than in the female. 



Abundant in the large ants' nests at Rannoch. I am 

 not aware of its occurrence elsewhere in the country.

Group XIII. Large species, ivitk the thorax strongly 

 punctured; penultimate joints of the antennoe transverse.

H. hrunnea is our only British representative of four 

 or five allied European species, and it is only in order to 

 facilitate reference, that I have associated it with H. 

 hepatica, which has a totally different facies. H. hrunnea 

 is a common species amongst moss, &c. H. hepatica I 

 have never found, and H. exarata occurs very rarely in 

 nests of Formica fuliginosa.
