Genus PERPERUS Schon., Gen. Cure, Genus, 241.

 Nothrodes Er., Wiegm. Arch., 1842. 

 Ce?Uyres Pasc, Ann. and Mag. Nat. Hist., 1871. 



These four names appear to appertain to hut one genus. Of the 

 typical species of Peruerus, I am acquainted with imwcuns Boh. 

 (stated by Blackburn — and I beUeve correctly so — to be a 

 synonym of languidus Er ) and insidaris Boh. (which 1 have noted 

 as a synonym of lateralis lioi.). I am also acquainted with the only 

 species {cervimis BoH.) referred to Pantopceus, and with the typical 

 species of Centyres (turgidus Pasc). 



Nothrodes is noted by Lacordaire as a synonym. 



PantopoiHS cervinus has a .rather more globular prothorax than 

 most other species, but otherwise has no claim to generic validity. 



Centyres was supposed to differ by the second third and fourth 

 abdominal segments being co-equal, but in turgidus the second is 

 slightly longer than either the third or tourth, although at a casual 

 glance it appears to be no longer; but in Perperus the second seg- 

 ment is subject to considerable variation, and I cannot regard it as 

 alone being sufficient to warrant generic rank.
