All the other characters as in tJie (^ . 
In the undeveloped form the elytra are scarcely half the length of 
the abdomen, rounded at the apex, without a distinct clavus or cimeus. 
but in the former the pitchy -black patcli is distinct. The membrane is 
rudimentary, and without cells. Abdomen above and beneath black 
and shining. Length Ij line. 
We are indebted to Mr. Bold, of Newcastle-on-Tyne, for both 
forms of this sex of this species. He found them together with the 
<;J''satthe roots of grass on the sea coast near Hartley, Northum- 
berland, and also in a similar locality to that in which the Eev. T. A. 
Marshall found the specimens we have previously described. 
The insect agrees in every way with Dr. Mor's description in the 
Rhyncoten Livlands, i., 472, 3, and thereby enables us to establish our 
G. afer, Eat. Mo. Mag , 248 (1866), as a distinct species.
