Tomicus.] EHTNCHOPHORA. 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. 5^-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; antenna? and legs ferruginous ; thorax longer than broad, 

 scabrous in front, finely punctured behind ; elytra with deeply punctured 

 striae, 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 striae of the elytra are broader behind than in the preceding 

 species and transversely rugose. L. 4f-5| mm. 



Under the bark of various Coniferse (Alies, Picea, Pinus, &c.) ; fortunately this 

 pest is very scarce in Britain ; London district (Stephens) ; Hyde, Cheshire 

 (Chappell) ; Scarborough. 



T. acuminatus, Gyll. Rufo-piceous, shining, clothed with pale 

 pilose pubescence ; antennae and legs testaceous ; thorax longer than 

 broad, scabrous in front and distinctly punctured behind ; elytra 

 scarcely longer than thorax, with rather fine punctured strise, interstices 

 with rows of smaller punctures, posterior excavation occupying less of 

 suture than in the two preceding species, but less abrupt than in thfe 

 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 stria? of the elytra and the formation of the posterior 

 excavation will easily separate this species from all the others. 

 L, 4 mm.

 Dukinfield, Manchester district (Chappell) ; Scotland, Forth, Tay and Dee districts
