Below I give an analytical table for recoginzing the genera in the tribe Chriopachides Thomspn. It will be seen that I have placed in this group the genus Schizonotus Ratzburg, which Dr. Arnold Foerster, in his Hymenopterologische Studien (1856), says is identical with Seladeram Walker, an opinion in which I cannot concur, my type of Schzonotus Siebaldi Ratz not agreeing at all with Walker's definition; also the genera Mesopolobus and Platymesopus Westwood, which were subpressed by Walker and other authorities, and placed in the genus Pteromalus; they agree in all essential characters with this group, the anterior femora being very similar to Chiropachys, the type of the tribe.
