tints), but has, in like manner, a 3-j orated funiculus and its feet moulded on the 

 same type. Although thus far coincident however with ITi/potheneitms, with 

 which it must consequently be admitted to have a very decided affinity, it is 

 almost needless to add that it offers abundant distinctive characters of its o-mi 

 which entirely debar it from association with that genus, — amongst which its com- 

 paratively gigantic size, its anteriorly um-oughened pronotum, and the eccentric 

 implantation, and nearly evanescent tliird joint, of its funiculus should be espe- 

 cially noticed.

Habitat per partem Maderae sylvaticam, in truncis Euphorbia mellifera, Linn. Phil., inter 3000' et 

 5000' s. m. nascentis, bine inde nou infrequens : in nemore illo Euphorbiarum in regione Fana- 

 lensi (prope lacum crateriformem Lagoa dictum) sito d. 17 Jul. a.d. 1851 primus copiosissime 

 inveni ; sed Augusto ineunte ejusdem anni pauca specimina etiam ad Ribeiro Frio cepi ; necnon

A. cylindrical, nearly opake, brownisb-black, and densely clothed with a short, fine and cinereous 

 pubescence. Prothorax most delicately and closely granulated all over (but with scarcely any in- 

 dications of punctures intermixed), and not at all more roughened in front than elsewhere, — where 

 however it is a great deal produced, somewhat acuminated, and of a dull lurid, or brownish- 

 yellow hue ; with an obscure dorsal ridge down the disk (more especially apparent posteriorly) ; 

 and with the hinder margin in immature specimens slightly diluted, or lutescent. Elytra closely 

 and rather rugosely subpunctulated (the punctures being small, ill-defined, and without any ten- 

 dency to be disposed in rows) ; the pubescence rather coarser and paler than on the prothorax ; 

 rounded and entire at their extremity (having no appearance of oblique tmncation) ; pale lurid- 

 yellow (often with a slightly olivaceous tinge), — with a greatly sinuated submedial fascia (the 

 lateral portions of which are oblique and transverse, and the central one suddenly looped back- 

 wards, and with its concavity turned towards the base), and a transverse subarcuated posterior 

 one (generally disconnected at the suture, and scarcely ever extending to the lateral margins), 

 black. Antenna and legs lurid-testaceous ; the former with their club a little picescent ; and the 

 latter with their tarsi very pale. 



An insect as truly indigenous as it is remarkable ; and one which might be easily 

 overlooked, even by a careful observer, from its (apparently) exclusive attachment 

 to the gigantic Tree Euphorbia {Euplwrhla melUfera, Liiin. Phil.) of elevated, and 

 more or less remote, inland spots. It was not indeed until my thii'd sojom-n in 

 these islands that I succeeded in detecting it : but, whilst encamped in the lofty
