 A very distinct species, characterised by the uniform colour of 

 the elytra and wings, and the form of the forceps, which recalls that 

 of somewhat elongated F. smyrnensis ; one male has the abdomen 

 very much telescoped, and so appears to be very small.

TRIPLAX BICOLOR, Gyll., A SPECIES OF COLEOPTERA NEW TO 

 THE BRITISH CATALOGUE. 



BT EICHARD S. BAGNALL, F.E.S. 



Early one morning in July, 1904, I came across a piece of fungus 

 growing on elm, in Gibside,in which occurred two species of Triplax, 

 and about a fortnight later the same species were met with in some 

 numbers at the same locality (Ent. Mo. Mag., 1904, p. 210 ; Ent. 

 Eecord, 1904, p. 260). The commoner of the two, which was in 

 hundreds, was easily identified as T. cenea, Schall., an insect usually 

 regarded as rare, but which I had taken not infrequently before in 

 this locality ; the others I supposed to be immature specimens of T. 

 russica, L., knowing them to be unlike any other species of British 

 Erotylidce, and at the same time having no example of russica with 

 which to compare my captures. I sent specimens of both insects to 

 Mr. Holland, as well as to many other Coleopterists, and in a letter 

 dated December 12th, 1904, Mr. Holland stated that my supposed 

 russica could not possibly be that species, as on comparing them with 

 authentic russica, he found several specific characters which at once 

 separated them from the latter; he thought that they would prove to 

 be T. bicolor, of Gylle)\hal, described by him in the " Insecta Suecica," 

 vol. i, p. 205. This letter came at a very opportune moment, shortly 

 before I left for Edinburgh to spend a few days with Prof. Beare, 

 where, with his kindly assistance, Mr. Holland's surmise was found 

 to be correct.
