'I'Ik; iirriin .Musenn» possesses several species from ^Mexico and |{ra/.il, willi a stipernnmerary cross-vein in tlie sul)- iinirj!;inal cell ; llic anxiliary cross-vein has its tip nearly opposite tlie (»ri};in of the second loii^:;itU(linal vein ; the unffiies have slnmuf luid distinct teeth ; the winj,^s are sjxitted. These species will form a distinct genus.* Another, still more alierrant form from South America, is rei)resented by several species in the sumo ninseum. In Mr. Hellardi's collection, in 'I'lirin, I have seen a species from tin; Philipiiine Islands, remarkalile for its coloring; it is hhick, with smoky wings; the thorax is orange red. As far as I can judge from the description of the genus PiTijihe- ropfcra Schiner( I'lrli. Zool. ISot. Ocs. etc. lS(!(i, p. !»;>:}, and (}. Sorara, etc. Di'iitcra, p. 47), it is only a form of iJirranotiujia; the generic character will be found in the Appendix II. Gen. I. DIC'RAIVOIflYIA. One subraarginal cell; fonr posterior cells ; diacal cell present or absent; marginal at the tip of tlie first longitudinal vein ; tip of the auxiliary vein generally opposite or before the origin of the secoiul longi- tudinal vein, seldom beyond it (wings of Dicrnnomijiir, Tab.
