2. XiPHiDiuM THORAcicuM, Fisch. de Waldheim. 



Differs from the preceding in having four small spines, instead of 

 two, on the outer margin of the undersurface of the posterior femora,

 recorded at Mirabeau, Vaucluse, and Pertuis ; in Spain, at Santiago 

 de Compostella, Santander, and Madrid ; in Portugal, at Coimbra ; 

 also in Sardinia. 



3. XiPHiDiUM dorsale, LatreiUe. 



Recognisable by the brilliant, almost oily, emerald- green colour, 

 reddish dorsal stripe, and short elytra and wings, which only attain 

 the length of the abdomen in an exceedingly rare variety. Length of 

 body, 12mm. -13mm. S' , 12mm. -15mm. ? ; of pronotum, 3mm. <? 

 and ? ; of elytra, 6-5mm.-8mm. 3' , 5mm.-6mm. J ; of ovipositor, 

 8-5mm.-9mm. ? . 



Locally, but widely, distributed in central Europe. It occurs in

 Isle of Wight, Studland, Pagham Marsh; in France it is found chiefly 

 in the north, Trappes, Montmorency, Meudon, Episy, La Bernerie, in 

 Brittany, Meuse, Drome, and also at Hyeres ; in Germany it is com- 

 moner in the north than in the south ; in Austria it is rather rare, but

 Gottland, in the Djurgarden, at StockholiiQ, at Tanglengs, and Marlebo 

 Myr; in Belgium, at Montplaisir, Ostend, Nieuport, Heyst, and
