Trichoptoryx.'] CLAVICORNIA. 119 



In dead leaves, moss, vegetable and flood refuse, hot beds, at roots of grass, &e. ; 

 very common and widely distributed. 



The large size, and long antennae, together with the quadrate elytra 

 and close sculpture, of the thorax s will easily distinguish this, perhaps 

 the commonest of our species. 



T. cantiana, Matth. This species is very closely allied to the 

 preceding, but diil'ers in having the thorax much less dilated at the sides 

 and base, and by its smaller head ; the antennae, moreover, are rather 

 shorter, more robust and entirely black, and the mouth parts are pitchy- 

 black ; the colour is deeper black and the pubescence is shorter. L. 

 i-1 mm. 



In vegetable refuse, moss, &c. ; rare; Tonbridge (Wollaston); Repton, Burton-on- 

 TYcnt, where I have taken a few specimens in Robins Wood from refuse at the side 

 of a pond. 



T. fascicularis, Herbst. Suboval, convex, rather dull black, some 

 what sparingly clothed with short pale hairs ; head moderate, eyes some- 

 what prominent, antennae clear yellow, occasionally obscurely yellow ; 

 thorax dilated behind, broadest at base, with small distinct tubercles, 

 arranged in sinuate rows, interstices deeply reticulate, giving the thorax 

 a dull appearance, posterior margin gently sinuate, posterior angles acute, 

 produced ; scutellum rather short and broad ; elytra longer, and a little 

 narrower than head and thorax, attenuated behind, asperate in thick, 

 transverse sinuate rows ; abdomen considerably exserted ; legs clear 

 yellow ; under-side black, with mouth and coxae yelloAv. L. 1-1 i mm. 



In vegetable and haystack refuse, faggots, dead leaves, ants' nests, &c. ; not un- 

 common and generally distributed. 



This species much resembles T. lata, but the antennas are shorter and 

 stouter, and the elytra are more narrowed behind, and the general 

 appearance is duller ; the sculpture also of the thorax is different. 



T. lootitia, Matth. Very closely allied to the preceding and very 

 likely only a local race ; it differs in its conspicuously smaller size, 

 smaller and more depressed thorax, and shorter and pitchy-black antenme. 

 T. fascicularis, however, sometimes has the antennae darker, and T. 

 hvtitia occasionally has them lighter, so that the latter character can 

 hardly be depended on. L. -|-|- mm. 



Robins Wood, Repton, Burton -on -Trent, where I took about forty specimens in 

 rubbish near the side of a pond ; Mr. Biliups has taken it near London, aud Mr. Allen 

 Marker near Gloucester ; it is probably widely distributed. 



T. seminitens, Matth. Oblong oval, black, thorax very shining, 

 elytra duller, convex, clothed rather sparingly with pale hairs ; head 

 large, eyes large and prominent, antennas slender, rather short, piceous ; 

 thorax very convex, much dilated behind, broadest at base, with rather 

 large tubercles, disposed in remote sinuate rows, interspaces very shining, 

 posterior angles broad and much produced ; scutellum large and broad ;
