Head rather small, indistinctly tuberculated ; eyes small, not prominent ; an- 

 tennse large, bright yellow. Thorax moderate, very convex, longer and broader than 

 the head, widest at the base, with the sides rounded and strongly margined, covered 

 with very small tubercles in indistinct wavy rows, with the interstices very shining 

 and faintly reticulated, posterior margin arcuated, with the angles much produced, 

 the margin and angles yellow. Scutellum very large, rather deeply asperate. Elytra 

 very convex, narrow, and much attenuated posteriorly, about as as long but narrower 

 than the head and thorax, faintly asperate in transverse wavy rows, with the apex 

 slightly rounded and pale. Abdomen obtuse, very much esserted, with five segments 

 uncovered, the terminal segment minutely tridentate. Legs moderate, bright yellow. 

 Under-parts dark castaneous, with the edges of the segments paler. 



Seven examples of tliis distinct and pretty species, wbicli may be 

 known by its narrow form and castaneous tint, were in the collection 

 of Mr. Cbampion. They were found some years ago in Wicken Feu, 

 near Cambridge.

Head large, broad in front, covei-ed with minute remote tubercles in nearly 

 straight rows, with tlie interstices shining and reticulate ; eyes large and rather 

 prominent ; antennae rather short, pitcliy-black ; palpi black. Thorax large, longer 

 and mucli wider than the head, very convex, widest before the base, with the sides 

 rounded and broadly margined ; the upper surface closely reticulated, or alutaceous, 

 with minute remote tubercles arranged in distant wavy rows, tlie posterior margin 

 faintly sinuated, with the angles broad, much produced, and dilated on their exterior 

 edge, somewhat in the shape of the bill of the PuiSn, Fratercula arctica. Scutellum 

 large, triangular, deeply asperate in transverse rows. Elytra short, slightly attenuated 

 posteriorly, about as long as but narrower than the head and thorax, moderately as- 

 perate in rather distant transverse rows, with the apices broad and rounded, yellow, 

 with the extreme edge white. Abdomen considerably exserted, broad, with the apex 

 obtuse, faintly tridentate. Legs rather short, robust, yellow, with the femora dusky. 

 Under-parts entirely black. 



This species may be distiugnisbed from others by the enlarged 

 and peculiarly curved posterior angles of the thorax, and also by the 

 superficial sculpture of the same part. In the British list it must be 

 placed after T. grandicollis, although several exotic species would in- 

 tervene. Three specimens were fouud by myself near Gumley.
