refers this insect to all Europe. It seems to be of the size of 

 P. attenuata, but to be narrower, more convex, more con- 

 tracted at each extremity, and with its head immersed in the 

 thorax, and perpendicularly inclined in front. 

 It appeal's to live on Sj)ergula arvensis.

 Mr. G. R. Waterhouse, in his notes on the species of 

 Triplax of Stephens' 111. and Coll. (Trans. Ent. Soc, vol. i, 

 3rd series, p. ii, 3 Dec, I860), has pointed out that one of 

 Stephens' T. hkolor {cenea, auct.) was refeiable to Lacor- 

 daire's species above quoted, and was in all probability 

 truly indii^enous. Lacordaire appears to have also referred 

 Stephens' ?'wj^co/Z/5 to this insect ; but the Stephensian species 

 of that name seems to be T. nigricepSj Lac. ; Mr. Crotch 

 lias accordingly (loc. cit.) re-named the French author's 

 ruficollisy described some years after publication of Stephens' 

 species of the same name ; and at the same time has ex- 

 pressed a doubt with regard to the true British character of 

 this and two others in the same genus. Dr. Pov^^er has, 

 however, recently taken a specimen of T. ruficolUs, Lac, 

 out of a fungus at Erith. 



It resembles 2\ cenea in size, but has black elytra, with 

 the interstices of the striae distinctly punctured and a black 

 «cutellum.
