PROSOPIS Fabricius 
Early in November, 1904, I took a specimen of Prosopis on flowers 
of Petroselinum sativum. As at this time the white Mimosz were 
flowering, I spent most of my time in hunting for the beautiful 
Pepsis, Eumenes, Montezuma, etc., visiting these shrubs. Only at 
the end of December, when the blossoming time of the Mimosa was 
over, did I remember the Prosopis found on the Petroselinum and 
began to watch this plant a little more carefully. In a few days I 
had the good fortune to obtain about fifty specimens of Prosopis, 
and nearly every day during January I added to the number. Now 
as this most attractive plant has ceased to flower I think it useful to 
record the species obtained. The fifteen species may be separated by 
the following table:
