When preparing my Paper on the Aplianarthra of these islands I 

 overlooked, as has been already stated, the present species, — having 

 (without accurate examination) regarded the two specimens from 

 which the above diagnosis has been compiled as merely immature 

 ones of the A. bicinctum. A more careful inspection of them, how- 

 ever, shows that (amongst other characters) they have the extreme 

 apex of their pronotum (which is not at all thickened or recurved) 

 armed with about four tubercles, of which the inner pair are com- 

 paratively elongated, acute, somewhat spiniform, and subapproxi- 

 mated. Indeed in this respect they approach the A. Jubas ; never- 

 theless, apart from the different shape of these minute projections 

 (the inner two of which are relatively longer, more porrect, and 

 placed closer together), the A. armatum may be immediately known 

 from that insect by its very much smaller size and by its consider- 

 ably shorter, finer, and more decumbent pubescence; by its alutaceous 

 prothorax (which is rather acuter, and less decidedly diluted, at its 

 extreme apex) ; by its entire punctation being closer and less coarse ; 

 and by its elytra (so far, indeed, as I am able to judge from the two 

 examples now before me) being ornamented by merely a large trans- 

 verse pallid fascia immediately behind their base. It was taken by 

 myself in Lanzarote (I believe, in the vicinity of Haria), along with the 

 A. Juhce, affine, and bicinctum.

Habitat in Gomera et Hierro, rarissimum. 



The rather small size and comparatively glahrous surface of this 

 little Aplianarthrum (the pubescence of which is so excessively short 

 and minute as to be quite untraceable except beneath the micro- 

 scope), in conjunction with its alutaceous and densely (though deli- 

 cately) punctulated prothorax, the extreme apex of which is some- 

 what lurid and has occasionally the faintest possible indications of
