BRITISH nUIIirTEEA — BESC'RirTIO'S OF SERIEUS PICIPES, A 

 NEW BRITISH SPECIES. 



BY EDWAED SAUNDERS, F.L.S. 

 SeIIIEUS PICIPES. 



Gydnus iiicipes, FiilL, Mon. Cim., 51, 4 ; Hem. Suec, i, 20, 5. 

 Gnatlioconus costalis, Fieb., Eur. Ilem., 3GG, 2. 



I am glad to be able to add this to our list of British Hemiptera ; 

 it is closely allied to 8. alhomarcjinatus, Fab., with wbicb it is not im- 

 probably mixed in some collections. Dr. Power, the other evening, 

 shewed me a few specimens found in the neighbourhood of Esher 

 and Wcybridge, by himself, which he had j^ut aside as distinct from 

 S. alhomarcjinatus, and from one of them I make the following 

 diagnosis : — 



Black, shining, deeply and rugosely punctured. Head scarcely 

 notched in front, extreme lateral margin of the elytra to a little below 

 the middle, ochreous-brown ; membrane milky-white. Antennje with 

 the apical joint scarcely longer than the 3rd ; legs black, tarsi paler. 



Length 2 lin. 



Distinct from 8. alhomarfjinatus by the narrow and darker margin 

 to the elytra, the pale colour of which does not extend on to the 

 corium adjoining, and is only A'isible on the basal half ; also by the 

 much less notched head, the shorter apical joint of the antennae, and 

 the pale membrane.

[I find that I have this species among some unexamined examples 

 taken many years ago by Mr. AV^ollastou at Mablethorpe, Lincoln- 

 shire.— J. W. D.]
