shorter ; with five, and sometimes six, apical areas. 

 Occasionally specimens may be seen with the mem- 

 brane almost entirely transparent, whilst in others the 

 fuscous-brown areas are marked out with wide yellowish 

 borders. Finally, specimens may be found of a sooty- 

 grey colour, with fine linear marks indicating the 

 elytral areas. Wings very short. Legs rufous-yellow 

 and spotted with black. Tarsi thick. Frons dark 

 brown or sooty-grey, with obscurely barred ochreous- 

 brown striations. Examples may be found with the 

 abdominal rings edged with yellow. 



Perhaps this is our smallest Deltocephalus. It occurs 

 everywhere, and is very common over all mid-Europe. 

 It is a hardy species, and lives throughout our winters. 

 In March, 1891, after the great snow-storm, I found 

 it quite numerous and active at the tops of the cliffs 

 at Ventnor, whilst the snow was still deep in the drifts. 

 I have specimens also from Malvern, Bristol, Norfolk, 

 Southsea, and elsewhere.
