231 IXSECTA MADERENSIA. 



— with which the extreme edges of the body are uniformly cihated. Prothorax verj' short and 

 transverse, and with the hinder margin sinuated ; thickly, but confusedly punctured, and densely 

 setose ; uneven, being roughened with obscure elevations and depressions, — amongst which how- 

 ever a broad longitudinal canal down the centre is exceedingly apparent. Elytra widest (and 

 very obtuse) behind ; lightly punctate-striated ; and the interstices, each, with a longitudinal 

 row of small tubercles, which are densely beset, or fasciculated, with rigid fulvous setae, — of 

 which the alternate series are somewhat the largest. Anteniue dull ferruginous. 



A common insect tliroughout Europe, and in the north of Africa ; Ijut apjia- 

 rently of the greatest rarity in ^Madeira, — if indeed (of Avhich I am by no means 

 certain) it be in reality indigenous. A single example only has hitherto come 

 beneath my notice, which was captured, many years ago, by the late Dr. lleincckcn, 

 from whose collection it was presented to me by the Eev. R. T. Lowe. It differs 

 in no respect from the ordinary type, except that its prothorax is perhaps a trifle 

 less distinctly punctured, and the tubercles of its elytra are almost equal through- 

 out, — the alternate series being scarcely at all larger than the intermediate ones.
