INSECTA MADERENSIA. 617 



M. wide, ferruginous, and almost unpubesceut (except on the abdomen, where it is clothed with a 

 short pile). Hcad,proihorax and elytra exceedingly roughened, and opake : the first studded with 

 distant granules, but only obscurely punctured ; expanded at the edges but truncated in front ; 

 incised on either side of its cljrpeus (within the anterior angles), and with a greatly elevated 

 ocellus in the centre of its hinder disk : the second much flattened and subrecui-ved towards the 

 sides (which are of a slightly clearer colour) ; coarsely punctured, but less evidently granided ; with 

 a wide, deep, glabrous and highly polished channel down the disk ; with its posterior angles 

 broadly sliced off along the basal margin (the incision ending abruptly nearly midway between 

 either angle and the centre) ; and sinuated at the base of its dorsal canal : the last, likewise, 

 expanded at the edges (but less so than the prothorax) ; and deeply and roughly subpunctured. 

 Abdomen a little shining, and, with the apical portion of the antenna, slightly obscured ; the 

 latter at their base testaceous. Leffs dull testaceous, or ferruginous. 



Apparently of the greatest rarity, two specimens only having hitherto come 

 beneath my notice, — one of which I captui-ed at the edges of the Levada of the 

 Ribeiro Frio, during the winter of 18i9 ; and the other, early in August of 1850, 

 at the Feijaa de C6rte,
