I. Apical declivity of elytra with a very distinct furrow on 

 each near suture; elytra without distinct longitudinal 



streaks at sides ; thorax black T. DOMESTICUM, L. 



II. Apical declivity of elytra without, or with an in- 

 distinct, furrow on each near suture; elytra with more 

 or less distinct longitudinal streaks at sides; thorax more 



or less red, at all events behind. 

 i. Elytra with the punctured striae moderately deep ; club 



of antenna) subsecuriform, straight on one side and 



somewhat rounded on the other T. QUEBCT/S, Etch. 



(signatum, F.) 

 ii. Elytra with the punctured strise superficial; club of 



antennae rounded on both sides and at apex . . . . T. LiXEAirif, 01. 



T. domesticum, L. Subcylinclrical, shining, clothed with scanty 

 pale pubescence and long pilose hairs, which are very distinct if viewed 

 sideways ; at first sight, however, the insect appears to be almost 

 glabrous ; head and thorax black, antennae testaceous or reddish- 

 testaceous with the club subsecuriform, straight on one side and some- 

 what rounded on the other ; thorax very convex, nearly as long as 

 broad, plainly tuberculate in front, shagreened or granulately rugose at 

 bnse ; scutellum distinct ; elytra livid testaceous or pale griseous- 

 yellow, with the suture and lateral margins black, with regular fine 

 punctured striae, interstices obsoletely punctured in more or less evident 

 rows, sutural strise deeper behind ; legs black, with the tarsi red. L. 

 2|-3i mm. 



Male with the forehead broadly and deeply excavate, and the villose 

 hairs on the anterior margin of the thorax thicker and longer. 



Female with the forehead convex and the thorax more strongly 

 asperate. 



In the dead wood of beech, alder, maple, birch, holly, oak, and probably other 

 trees; local; Mickleham: Shirley; Westerham, Kent; Brasted, Surrey ; Hastings 

 district; New Forest; Dean Forest; Sutton, near Birmingham; Hopwas Wood, 

 Tamworth ; Sherwood Forest ; Stretford and Dunham Park, Manchester ; Scar- 

 borough, in solid wood of dead holly (E. Lawson) ; Northumberland and Durham 

 district ; Scotland, rare, Solway, Dee and Moray districts ; Ireland, Westport, Co. 

 Mayo (J. J. Walker). 



T. quercus, Eich. (signatum, F.). Very like the preceding in 

 general appearance, but with the elytra of a less livid testaceous colour, 

 and the thorax always more or less red, at all events behind ; it may 

 easily be distinguished by having a broad longitudinal dark band be- 

 tween the suture and side margins, which is sometimes much abbre- 

 viated or divided and sometimes only visible at apex, but is rarely 

 absent ; the apical declivity of the elytra has no furrow near suture ; 

 the striae of the elytra are also more distinctly punctured, and the legs 

 are red or brownish red ; the club of the antennae is shaped much as in 

 T. domesticum. L. 3| mm. 



In dead wood of oak, beech, birch, maple, lime, Ac.; not common, or rather very 

 local ; it occurs in considerable numbers in Sherwood Forest, where it has beeu
