ON CERTAIN BRITISH HEMIPTERA-HOMOPTERA. 

 BY JOHK SCOTT. 



Description of a neio genus and sjjeeies of the fcnnily DELPnAcrDj;. 

 Genus EUEYBREGMA. 

 ^. Developed form. 



Head — crown almost twice as broad as the lengtli measured down 

 tlie centre ; central keels obsolete ; base with two deepish fovea; with 

 the usual M-shaped marginal keels, and in the apex of which exteriorly, 

 is a third small fovea, anterior margin slightly convex, but a little way in 

 front of the eyes. Face with rudimentary indications of two keels, 

 approximating and uniting at the apex ; side margins slightly concave 

 between the eyes. Antennce short, reaching to or a little beyond the 

 base of the clypeus ; 1st joint longer than thick, somewhat cylindrical, 

 and shorter than the slightly clavate 2nd joint. 



Thorax — pronotmn : side keels near to the eyes, curving round 

 parallel with their posterior margin and not reaching the lateral mar- 

 gin. Scutellum with a central and two side keels, the former not 

 reaching the apex, the latter almost parallel wuth the former, joining 

 the sides at the base of the triangle. Legs — tihice : spur at the apex 

 of the Si'd pair triangular, flat ; lower margin convex, finely serrate. 

 Tarsi : 3rd pair, 1st joint long, equal in length to the other two. 



This genus stands near to that of Eurysa, Eieb., but llie greater 

 breadth of the head, difference in the side margins of the face between 

 the eyes (in Eurysa these are convex), and form of the genitalia, at 

 once shew their distinctness. 



Species Etjetbeeoma niorolixeata. 



Head fuscous-brown. JPronotiim and scutclhim yellow, each with 

 two black longitudinal lines. Elytra much longer than the abdomen, 

 pale testaceous-white ; nerve adjoining the anterior margin and the 

 nerve adjoining the claval suture broadly margined with brown, be- 

 coming darker as it reaches the transverse nerves, from whence to 

 round the apex it is broadly black. 



Sead — croion fuscous-brown ; foTCse black, keel between the two basal ones yellow. 



F<ice fuscous-brown, paler towards the apex ; on each side between the latter 



and the lower margin of the eyes an oval black patch. AntenncB pale yellow, 



sliijhtly dusky. 

 Thorax — ^ronotum pale yellow, lateral margins and a streak down each side of the 



centre black, in the middle of the latter a small fovea. Scvfellmn orange-yellow ; 

 . side keels black ; central keel white. Elytra pale testaceous-wliite. Clavus :
