CLAVICOKNIA. 123 



shining, black, clothed with very short yellow pubescence ; head rather 

 small, eyes large, prominent, antennae moderate, rather stout, pitchy- 

 black ; thorax short, broadest at middle, with small tubercles arranged 

 in thick strongly sinuate rows, interspaces shining, deeply reticulate, 

 posterior margin almost straight, angles scarcely produced ; scutellum 

 large ; elytra oblong, very convex, with the sides almost parallel, thickly, 

 but not deeply, asperate ; legs yellow. L. -1 mm. 



In hot-beds, vegetable refuse, &c. ; rare, but probably much more widely dis- 

 tributed tliau is at present known; Tonbiidge; Gumley, Leicestershire; Knowle; 

 Uepton ; Lincoln ; in. both the latter places I have taken it in the hot-bed in my 

 garden ; Mr. Champion h;is also found it in Scotland. 



This species is allied to T. picicornis, but differs in its shorter and 

 narrower thorax, longer and more slender antennae, and closer and finer 

 sculpture. 



T. picicornis, Mannh. Oblong, convex, black, rather sparingly 

 clothed with yellowish hairs; head lar^e, antennae moderate, pitchy- 

 black, with the eighth joint somewhat incrassate ; thorax scarcely dilated 

 behind, with sides rounded and margined, furnished with moderate 

 tubercles arranged in thick, interrupted, rows, interspaces deeply reticulate, 

 posterior angles moderately produced ; scutellum rather small ; elytra 

 quadrate, slightly broader behind, with sides almost parallel, moderately 

 strongly asperate ; abdomen rather much exserted, apical segment tri- 

 dentate ; legs rather stout, obscurely yellow; basal joints of all the 

 tarsi slightly dilated ; under-side black, mouth and coxse lighter.

In rotten wood ; rare; Hastings; Knowle ; Gumley ; Sherwood Forest ; Northum- 

 berland district, six specimens (Bold) ; Scotland, Forth and Tay districts (Avie- 

 more, &c.). 



T. carbonaria, Matth. This species is allied to T. picicornis, but 

 differs from that species in its paler and more slender antennae, of which 

 the eighth joint is linear and not incrassate, and in the different sculpture 

 of the thorax and elytra, the tubercles on the former being smaller, and 

 the latter being deeply and very closely asperate. L. f mm. 



A single example wns taken in August, 1868, by the llev. A. Matthews in Thorcsby 

 Park, Nottinghamshire, by sweeping under oaks. 



T. Jansoni, Matth. Oblong, subcylindrical, subparallel, deep black, 

 clothed very sparingly with short silvery hairs ; head short, very broad, 

 antennae rather long, pitchy-testaceous or yellow ; thorax scarcely dilated 

 behind, with sides rather broadly margined, with moderate tubercles, 

 arranged in irregular remote sinuate rows, interspaces very shining, 

 deeply reticulate, posterior angles rather distinctly produced ; elytra 

 rather long, parallel-sided until behind middle, and thence rounded to 

 apex, deeply asperate in remote, transversely sinuate, rows; legs 

 moderate, clear yellow ; under-side black, with mouth, coxae, and apex 

 of metastemum, yellow. L. mm.
