Common everywhere. Germar's description precedes Say's by several 

 months. Say in the Bost. Journal misquotes himself, as there is no description 

 of this species to be found in the Journal of the Academy of Natural Sciences.

Malthinus abdotninalis Dej. Cat. My specimen of this species 

 is too imperfect for a satisfactory reference to any of the genera described 

 above. From the form of the thorax and elytra, I think that it belongs to the 

 genus alluded to as found at Panama. The following diagnosis will enable the 

 species to be recognised : Rufus, capite pone oculos nigro, thorace quadrato, 

 lateribus rectis, basi rotundato, ad medium late transversim concavo, elytris 

 fuscis, subtilissime scabris, pedibus fuscis. Long. 26. Georgia; rare.
