ADDITION TO THE LIST OF BRITISH EEMIPTEBA. 

 BY EDWARD SAUNDERS, E.L.S. 



Amblytylus DELICATUS, 



Perris, Nouv. Exc. dans les Grandes Landes, Extr. Ann. Soc. Linn., 

 Lyon (1857), p. 87 ; Reuter, Hem. Gym. Eur., ii, p. 210. 



$ narrow, almost like an Orthotylus in form. ? more resembling afflnis. Pale 

 yellowish-green, clothed with very fine whitish hairs, with occasional longer brown 

 bristles on pronotum and hemelytra. Head green, about as long as wide. Antenna 

 finely pubescent ; basal joint with a few dark bristles, 2nd joint slightly longer than 

 the 3rd, and in the $ considerably thicker. Rostrum extending to about the middle 

 of the abdomen in the $ , or beyond the middle in the $ . Pronotum about twice 

 as broad at the base as long, green in front, paler ochreous behind, anterior margin 

 about three-quarters as long as the base, sides nearly straight, marginate anteriorly. 

 Hemelytra extending much $ , slightly $ , beyond the apex of abdomen, pale ochreous, 

 inclining to green on the clavus ; cuneus and apex of corium of a browner colour, 

 and clothed with brown semi-erect hairs ; in the ? the disc of the corium has 

 numerous brown-black hairs intermixed with the shorter pale ones, but in the $ 

 these are very scattered and scarcely noticeable. Membrane lacteo-hyaline, nerves 

 pale, its inner margin dark at the baBe, where it unites with the corium; cells brown 

 at their apices, and below them a brown spot extends from the apex of the cuneus 

 to the apex of the larger cell, leaving the triangular space between the apex of the 

 cuneus and the smaller cell pale and clear. Abdomen green above and beneath ; 

 legs pale ; femora with a few very indistinct spots near the apex ; tibiae with pale 

 brownish spines. Length, 4J — 5 mm. 



Hab. on Gnaphalium germanicum, W oking ; rare. 

 . May be at once known from any of our British species by its 

 colour and tbe peculiar marking of the membrane. 



I have only succeeded in taking a few of each sex of this insect 

 after many hours' search. The locality is close to my house, and 

 Gnaphalium germanicum is abundant everywhere, but only on one spot, 

 about 20 yards square, have I been able to meet with Amblytylus. 

 The plant is more abundant and in much denser masses on the opposite 

 side of the road to that on which the insect occurs, but it appears 

 to be tenantless, so far as the Amblytylus is concerned. It is rather 

 curious that Orthotylus adenocarpi, Perris, = Douglasi, E. S., and 

 Amblytylus delicatus, Perris, both occurring in " Les .Landes," should 

 both have been introduced from Woking. I have little doubt that I 

 am right in referring my insects to Perris' species, as I have a specimen 

 of delicatus from him which, although old and faded, appears to agree 

 with mine in all essential points, and, moreover, Dr. Eeuter's descrip- 

 tion, cited above, agrees -well with it, although he only appears to 

 know the $ .
