tibiae fuscous. Common in N. Europe. This species seems 

 to vary very little, and could only be confounded with T. 

 lividus, var, (3, ; but the entirely black vertex and conco- 

 lorous knees at once distinguish it. 



8. lividus, L. Mars. 37. 5 — 6 lines. Var. dispar, F. — 

 Testaceous ; a spot on the vertex, knees and posterior tibiae 

 black. One of the most variable and abundant of our spe- 

 cies. The elytra vary through a regular gradation to a deep 

 black, which colour even invades the legs. In all its forms 

 it is at once known by its singular orbiculate thorax, which 

 has the margins broadly expanded, and by the black dash 

 on the vertex. 



9. assimilis, Pk. (1798). Mars. 41. ^—^ lines.— Black ; 

 thorax rufo-testaceous ; disk more or less black ; elytra and 

 tibiae testaceous. This species appears to be nowhere com- 

 mon, though distributed over North and Central Europe. All 

 the specimens I have seen from this country have been 

 brought by Turner from Scotland, and have been generally 

 referred to Rhagonycha, but they are true Telephori. It is, 

 I believe, the sp. ? of Mr. Waterhouse's ' Catalogue,' and is 

 certainly the species I registered with doubt as the T. femo- 

 ralis, Br., which resembles it in coloui-ing, but is a true Rha- 

 gonycha by its claws, and has not, so far as I am aware, 

 occurred in Britain as yet. T. assimilis is very vai'iable in 

 the coloration of the thorax and legs, but its black antennae 

 at once separate it from any species with which it might be 

 confounded. It may be worth observing that the Scotch 

 specimens are markedly smaller than the continental ones. 



10. ^//wm/Ms, Mannh. (1843). Mars. 45. 3— 3^ lines.— - 

 Testaceous ; vertex, an angular discoidal spot on the thorax 

 and the base of the legs black. Also a very variable species, 

 apparently rare in this country, though probably confounded 

 with liturata. Fall. My own specimens, which are all I have 

 yet seen, were taken at Cambridge, with the allied species. 

 The legs, as in my specimens, are sometimes entirely pale. 

 The best character for this species is its black scutellum, but 

 its form is very different also. The head is narrowed behind 

 conspicuously, and the thorax is very different from T. rufa. 



11. rufus, L. Mars, 47. 4 — 4|- lines. Var. liturata, Fall. 

 — Entirely rufo-testaceous. This form is, however, much the 

 rarest in this country, though commonest abroad : here the
