The rufous head and elytra (the latter of which, however, are rather 

 obscured anteriorly) of this minute Trogopliloeus, whilst its head and 

 abdomen are black and its legs testaceous, will sufficiently distinguish 

 it. Its prothorax has the dorsal impressions obsolete, but is lightly 

 marked behind with a transverse (sometimes evanescent) fovea, and 

 (together "with the head) is very densely and coarsely alutaceous ; and 

 its elytra are somewhat sharply punctured. It is extremely rare, the 

 few specimens which I have seen having been taken by myself at La 

 Antigua in Fuerteventura and near the Puerto Orotava in Teneriffe.

T. subopacus, niger vel fusco-niger, subtilissime densissimeque cine-

 In its minute size, and very densely, delicately, and evenly punc- 

 tulatcd head and prothorax, the latter of which is perfectly free from 

 all traces of impressions or foveae, this little Trogo])Jiloeus has evidently 

 much in common with the T. simplicicoUis of the Madeiran Group ; 

 nevertheless (although I have at present no type of the latter for 

 comparison) I am satisfied (both from recollection and the diagnosis) 

 that it is truly distinct from it. It is remarkable, inter alia, for its 

 head being rather large and wide (/or a TrogojMceus), for its pro- 

 thorax being narrow and elongate (instead of transverse), and for its 

 entire colour (except the legs, which are pale testaceous) being of a 

 dark brownish-black. Its wings are immensely developed ; and its 

 antennae are abbroviated— with their basal joint a little longer, the 

 second a trifle more enlarged, and the following ones shorter, than is 

 the case in the TroyopJdcei generally. It is extremely local, but per- 

 haps not uncommon if searched for in the proper situations ; though 

 its very diminutive size renders it liable to escajje detection. On one
