103 STAPH YLiNiDiE. \_Hor>ialuta. 



body with ventral 23late longer and narrower and more rounded at apex 

 than in feruale. 



Tu decaying fungi, dead leaves, &e. ; Mickleham and Caterbam, Surrey (Champion); 

 Scotland, local, Tay and Forth districts (in numbers iu a ditch among dead leaves in 

 early spring on the Braid Hills, Edinburgh (Sharp). 



The antennae of this species are usually rather more obscurely testaceous 

 towards apex than at base. 



Hi parallela, Mannh. {talpa, Heer, Amidohia paraUela, Thorns.). 

 This species, as remarked above^ is in some points different from the 

 others belonging to this group ; it is rather like //. analis, but differs in 

 the impunctate and shining extremity of the hind body and the shape of 

 its head ; it is black with the elytra brown and the apex of hind body 

 testaceous; head rather large, rounded at sides, smooth and shining; 

 antennae rather longer than in the preceding species, yellowish, 

 second joint longer than third, fourth nearly quadrate, 5-10 strongly 

 transverse, eleventh not as long as the two preceding ; thorax transverse, 

 finely punctured ; elytra rather longer than thorax, thickly and finely 

 punctured ; hind body with basal segments finely and indistinctly 

 punctured, apical segments smooth; legs yellow. L. 1| mm, 



Male with upper and lower plates of seventh segment of hind body 

 more strongly rounded in tlie male than in the female. 



Scotland ; in nests of Formica rufa in the Tay and Dee disti'icts ; abundant in the 

 large ants' nests at Raiinoch and Braemar ; it has also been taken at Scarborough 

 by R. Lawson, and two specimens have been recorded from Wallasey, near Liverpool, 

 by Dr. J. W. Ellis. 



According to Mulsant and Eey the elytra in this species are a little 

 shorter than the thorax ; they appear to vary somewhat in length. 



Section V. 



Abdomen parallel ; thorax distinctly or strongly transverse ; penulti- 

 mate joints of the antennae not, or but moderately, transverse. 

 This section may be divided into the following three groups : — 



13. Large species, with the thorax strongly punctured ; penultimate joints of the 

 antennae transverse (p. 102). 



14. Large species, with the penultimate joints of the antennse not transverse 

 (p. 104). 



15. Moderately-sized, or small species, with the penultimite joints of the antennsa 

 transverse (p. 106). 



Group 13. 



This group contains three or four species, of which one or two are 

 somewhat doubtful. H. brunnea, Fab., and H. depressa, Gyll., are con- 

 sidered by several authors to be identical, but by others they are 

 separated as distinct species ; H. hejiatira and H. exarata too are classed
