Verf. beschreibt eine neue Diplosisart, deren Larven zwischen 
Samen und Samenhülle von Sorghum schmarotzen und dadurch das 
Verschrumpfen der Samen verursachen. Sie treten in Nord-Ame- 
rika verheerend auf. Diplosis sorghicola n.sp. d2, Ala, Tex. 
Die Verwandlung findet an derselben Stelle, wo die Larve lebt, 
statt, darum stehen dem Menschen keine Vertilgungsmittel zu Gebote.
