Head moderate, faintly punctured, shining ; eyes moderate, rather 

 prominent ; antennae pale yellow, with the three apical joints con- 

 siderably incrassated. 



Thorax large, very convex, not depressed at the base, much dilated 

 posteriorly, with the sides considerably rounded and slightly mar- 

 gined; covered with very minute tubercles placed in remote 

 oblique rows, with the interstices faintly alutaceous ; posterior 

 margin nearly straight, with the angles very much produced, and 

 widely pale. 



Scufellum moderate, triangular, short, broad, and acuminate ; closely 

 and very finely asperate. 



Elytra paler than the head and thorax, short, and much attenuated 

 posteriorly, narrower than the thorax, and not as long as the head 

 and thorax united ; faintly and rather remotely asperate, with the 

 apex nearly straight. 



Abdomen moderately exposed, black. 



Legs bright yellow. 



ITnder-parts castaneous, with the mouth, coxae, and apex of the 

 abdomen bright yellow. 

 This species may be known by its short attenuated shape (which 



is intermediate between T. atomaria and T. fenestrata), hj the sculpture 



of the thorax, and by the more incrassate club of the antennae. It 



appears to be rare, and has only been found in Gomera, where five 



examples were captured by Messrs. Crotch. 



T. CANABIENSIS, n. S. 



L. c, i^ lin. Oblong, sub-parallel, moderately convex, intensely 

 black, very sparingly clothed with a short dark pubescence ; the thorax 

 scarcely dilated at the base, covered with large and strongly elevated 

 tubercles, placed without order, with the interstices strongly alutaceous ; 

 the elytra long and parallel ; legs bright yellow, and antennae pitchy- 

 black. 

 Head large and wide ; eyes moderate, not prominent ; antennae rather 



short and stout, pitchy-black. 

 Thorax small, a little wider (but scarcely longer) than the head, a 



little widest behind the middle ; covered with large tubercles, 



placed without order, with the interstices strongly alutaceous ; the 



base slightly depressed, the posterior margin nearly straight, with 



the angles large and moderately produced. 

 Seutellum very large, triangular, asperate in straight, transverse, and 



remote rows.
