Innarius, I have experienced most discourcaging dif- ficulties from the Avant of sullicieiit series of the Old World races, and I'roni the unsatisfactory character of most desciiptions and iigures of them, besides being much perplexed by the confusion of their .synonymy by ditVercnt authors. Tn conseiiuence of this, my diagnoses of the four races of which alone I have seen examples may be very unsatisfactory as regards the charactc's by which tliey may be most readily distinguished. Having seen the adult of oidya single one of these four races, I am therefore compelled to base my differential characters upon the immature stages. In addition to the four races of /'. faiitirii(s characterized above, there are several geognii)hical forms belonging to tlie Old World, chiefly intertropical Asia and Africa.
