118 CLAVICORNIA. \Trichoptfiryx. 



In moss, haystack refuse, &c. ; locnl ; London district, rare, Sheeruess, Chatham, 

 and Reigate ; Hastings ; Smallhf ath, Edgbaston, and Knowle ; Repton, near Burton- 

 on-Treut, common in hot-bed in my garden ; Sherwood Forest, not uncommon ; it is 

 probably widely distributed. 



The species may be known by the elytra being strongly attenuated 

 behind in male, the short dark antennae, and the sculpture of the thorax, 

 which is like that of T. sericans but with broader interspaces. 



T. fratercula, Matth. Rather short and broad, black, shining, 

 clothed with short yellow hairs ; head large, broad in front, eyes large 

 and rather prominent, antennae rather short, pitchy-black ; palpi black ; 

 thorax large, very convex, widest before base, upper-surface with minute 

 remote tubercles arranged in distant wavy rows, closely reticulated, or 

 alutaceous, posterior angles broad, much produced, and dilated on their 

 exterior edge, somewhat in the shape of the bill of the Puffin, fratercula 

 arctica (hence the name of the species) ; scutellum large ; elytra short, 

 slightly narrowed behind, narrower than head and thorax, moderately 

 asperate ; abdomen considerably exserted ; legs rather short, robust, yellow,

Three specimens of this species have been taken by Mr. Matthews at Gumley, near 

 Market Harborough, by sweeping.

 behind middle ; legs yellow, under-side black, with the mouth testaceous 

 or piceous, and the coxae black, margined with yellow. L. 1-1 1 mm. 



In moss, cow-dung, vegetable refuse, &c. ; common and generally distributed in 

 England ; it sometimes occurs in great profusion ; it appears, however, to be rarer in 

 the north and in Scotland; Ireland, near Dublin, &c. 



This species is very easily recognized by the three long outstanding 

 sctce on each side, which are possessed by no other British species.
