Tomicus. | RHYNCHOPHORA, 441 
suture, circular and shining, and furnished with six teeth on each side, 
of which the fourth from the upper surface is the largest. L. 53-7 
mm. 
In fallen or recently dead firs; rare; London district and Swansea (Stephens) ; 
Dukinfield, Manchester district, in some numbers (Chappell). 
T. typographus, L. (octodentatus, Payk.), Smaller than the pre- 
ceding, pitchy black, but variable in colour, sometimes being light brown 
or testaceous, rather shining, clothed with long greyish-yellow villose 
pubescence ; antenne and legs ferruginous; thorax longer than broad, 
scabrous in front, finely punctured behind ; elytra with deeply punctured 
striz, and the apical excavation of the elytra much as in the preceding 
species, but dull and furnished on each side with four teeth, the third 
being the largest, and the first or uppermost being often indistinct ; the 
sutural strie of the elytra are broader behind than in the preceding 
species and transversely rugose, L, 45-53 mm. 
Under the bark of various Conifers (Abies, Picea, Pinus, &c.); fortunately this 
est is very scarce in Britain; London district (Stephens); Hyde, Cheshire 
(Chappell) ; Scarborough. 
T. acuminatus, Gyll. Rufo-piceous, shining, clothed with pale 
pilose pubescence ; antennez and legs testaceous; thorax longer than 
broad, scabrous in front and distinctly punctured behind; elytra 
scarcely longer than thorax, with rather fine punctured strie, interstices 
with rows of smaller punctures, posterior excavation occupying less of 
suture than in the two preceding species, but less abrupt than in the 
two following, shining, punctured, with three teeth on each side, the 
lowest one being the largest ; in the female the third tooth is bent into 
a hook ; the fine stric of the elytra and the formation of the posterior 
excavation will easily separate this species from all the others. 
L, 4 mm. 
Under bark of firs and pines; local; Robin’s Wood, Repton (W. Garneys) ; 
Dukinfield, Manchester district (Chappell) ; Scotland, Forth, Tay and Dee districts
