I have only found on Papilionaccie. In this group come pisi 

 Kaltenbach, ononis Koch, and apparently two new species 

 which I propose to call loti and Irijolii. 



B, the ulmaricB group, in which the cornicles are reticulated 

 at their apices and again have sensoria on the third antennal 

 segment only. In this group come ulmarice Schrank, get 

 Koch, and slcllarice nov. sp.
