In moss; very rare ; taken by Mr. Matthews near Gumley. 



This species appears somewhat to resemble T. brevis, but differs in 

 its smaller thorax, longer and more slender antennae, and also in 

 sculpture. 



T. Waterhousii, Matth. Oblong, subparallel, somewhat depressed, 

 nigro-fuscous with the elytra testaceous, clothed with short pale hairs ; 

 head large, eyes not prominent, antennae moderate, bright yellow, with 

 the apical joints only slightly incrassate ; thorax short, scarcely dilated 

 behind, with the sides very slightly rounded, with small distinct tubercles, 

 irregularly arranged inclose rows, interstices slightly alutaceous, posterior 

 margin yellow, angles slightly produced ; scutellum large, dull black ; 

 elytra short, quadrate, slightly dilated towards apex, sides nearly straight, 

 finely asperate ; abdomen fuscous, moderately exserted ; legs yellow ;

 coxae yellow. L. f mm. 



Two examples taken in Britain by Mr. Waterhouse ; locality unknown. 



T. Chevrolatii, All. (pygmcea, Er.; minuta, Mots.). The smallest 

 species of the genus that we possess ; short, oblong, parallel, somewhat 

 depressed, black, rather shining, clothed with rather long whitish 

 pubescence ; head large, eyes prominent, antennae rather long, entirely 

 pitchy, last joint elongate ; thorax quadrate, scarcely dilated behind, 

 with small inconspicuous tubercles ; scutellum large ; elytra short, 

 quadrate, moderately asperate in transverse rows ; legs robust, clear 

 yellow, with the basal joints of all the tarsi slightly dilated ; under- 

 side nigro-piceous, with the mouth, metasternum, and coxse yellow. 

 L. f-f mm. 



In vegetable refuse, hot beds, &c. ; probably very often overlooked by reason of 

 its minute size; Shirley ; Tonbridge ; Gumley, Leicestershire; Edgbaston and Knowle, 

 Birmingham. 



This species may easily be recognized by its very small size, oblong 

 and parallel form, quadrate thorax, elongate last joint of antennae, and 

 very fine sculpture. 



T. suffocata, Hal. Oval, rather broad, somewhat depressed, black, 

 clothed with pale pubescence ; head rather elongate and prominent, eyes 

 large and prominent, antennae moderate, clear yellow ; thorax small,
