84 COLEOPTERA. 



district, most probably near Higbgate) is, bowever, clearly 

 to be referred to H. testaceum. It is ratber smaller tban 

 H. concinmim, rufo-testaceous, witb tbe bead and apex of 

 abdomen more or less darkened ; the antennse are longer, the 

 head duller, being more closely and almost strigosely punc- 

 tured, tbe thorax is duller, more closely punctured, wider, 

 witb the sides not so evidently contracted behind, and the 

 punctures of the elytra not running so clearly into striae. 

 In the original record of the species as British, the thorax, 

 compared with that of 0. concinmim, is stated to be much 

 smaller and narrower; a description which, if it be not 

 accidentally wrong, w^ould almost throw a doubt as to its 

 correct identification. Erichson says of both testaceum and 

 concinnum^ " thorax coleopteris parum angustior," adding, 

 as regards testaceum^ " latitudine plus dimidio brevier," and, 

 as regards concinnum^ " latitudine dimidio brevior," wdiich 

 would have the effect of making the thorax of testaceum 

 look comparatively tbe under of the two. The testaceous 

 ^'- HeerV var. of vile is somewhat suggested by the nar- 

 rower thorax. H. testaceum is recorded by M. Fauvel 

 from various parts of France, and stated to occur under 

 leaves, moss, and oak bark, in forests, both in plains and 

 mountainous districts.
