NEW BRITISH SPECIES NOTICED IN 1859. 105 



The present species, which Erichson, Redtenbacher and 

 Heer confounded with T. marginellus, F., may be re- 

 cognized by its usually larger size and comparatively greater 

 breadth ; its elytra are appreciably shorter and more convex, 

 and their margins and those of the prothorax are ferruginous, 

 not testaceous, as in marginellus. The space between the 

 two intermediate processes at the apex of the seventh inferior 

 segment of the abdomen of the male is twice as wide as in 

 marginellus, and the processes themselves are distinctly 

 longer ; the same differences obtain, but in a less degree, in 

 the female. 



Found by Mr. Constantine, near Blackburn.

 Greatly resembling, and of our ascertained indigenous 

 species, most nearly allied to Euryporus picipes, Payk., but 

 having the antennas elbowed almost as in Cryptobium, the 

 basal joint fully as long as the four succeeding joints taken 

 together, slightly curved.
