 elytrorumque nmrginibus late testaceis: caput prothorax et

This species is the Anom. Auro-limhata of the Parisian col- 

 lections, and of the Count Dejean's catalogue ; iheAjiom. tiridis 

 of Mr. Kirby's cabinet, now in the possession of the Entomo- 

 logical Society; and the Anom. Confucius of Mr. Hope's cabinet. 

 I believe it has never previously been described.

Instrumenta cibaria fere Cychri sed non eadem : mandibulse intus 

 dentibus 2 minutis distantibus instructae: prothorax fere cordatus, 

 postice restrictus, truncatus, lateribus, carina marginali elevati 

 instructis : elytra prothorace duplo latiora, convexa, lateribus 

 rotundatis, carina marginali elevata recurva instructis. 



Irichroa vidua. Newman. 



Cychrus unicolor. Say. 



Cychrus unicolor. Knock. 



Cychrus viduus. Dejean. et Say in litteris. 



This beautiful insect possesses a form and character perfectly 

 distinct from the species of Cychrus which inhabit the Old 

 World, as much so, in fact, as Scaphinotus, and far more so 

 than Sphaeroderus of Dejean.
