separate off callose prominences on sules in front, and with fine central 

 furrow, the three furrows terminating in punctures at base, which are 

 situated in a semicircular line ; elytra much broader than thorax, convex, 

 broadest behind middle, finely and very obsoletely punctured with an 

 entire sutural stria and a very short dorsal stria, humeral prominences 

 distinct ; abdomen about as long as elytra very finely ininctured ; legs 

 red, femora thickened in middle, tibiae thinner at base. 1^. 2 nun. 



Male "with the last two joints of antennae larger than in female, the 

 ninth being obliquely truncate at apex, and the intermediate femora with 

 a very minute spinule in middle ; the last ventral segment of alidomen 

 also in this sex is foveolate. 



In ants' nests, usiially in old trees ; also in rotten wood-nionkl of old oak, ash, and 

 beech trees ; IocmI ami as a rule rare; Ashtead, Surrey (Clirtinpioi)) ; Lougliton, Essex ; 

 Birch Wood and Purley Oaks (Power); B.irham, Hullblk ; New Forest; Bago!s 

 Park, Stattbrdshiro, and near Gaiusboroush (Gorhani) ; Sherwood Forest (IJhitch) ; 

 Shrewsbury ; Ripon ; I have taken it at Sherwood Forest in a nest of Formica full- 

 ciiiiosa in an old tree, and at Ulting, near Maldon, Essex, in an old oak stump with 

 Paromalus, AbrcBus, &c. ; it appears also to occur with Formica rufa and Lasius 

 irunnens,

This genus, which has until recently been included under Brj/axis, 

 comprises a considerable number of species which are widely distributed 

 throughout the world ; it is distinguished from Bryaxis by having the 

 inflexed margin of the elytra longitudinally sulcate, by the sculpture of 

 the thorax, and by the structure of the apex of the elytra in male ; in 

 our sjiecies the male has the antennse much longer than in the female ; 

 it was therefore described as a separate species by Denny.
