56 AUSTRALIAN NEUROPTERA. Part ii. By Esben-Petersen, Silkeborg. (Plates vi.-xiii.; and two text-figs.) (Communicated by TF, W. Froggatt, F.L.S.) In the following notes, which may be looked upon as prelimin-ary ones only, I hope to give a contribution to the knowledge of the Australian fauna of Myrmeleonidee. Unfortunately, ] have not been able to work out the two large genera MyrmeUon and Formiccdeon, so that lack of material necessitates the postpone-ment of this work until more material is at hand. My best thanks are due to the (lOvernment Entomologist, Mr. W. W. Froggatt, and to my friend, Mr. R. J. Tillyard, for loans and gifts of material. Table of Genera of Australian Myrmeleonid.^.. l.ln the hind wing, only one crossvein (rarely two) before the origin of the radial sector 2. In thehindwing, tliree or more crossveins before the origin of the radial sector 12. 2. No spurs •>• Spurs present 5. 3. In theforewing, lA runs directly into the hindmargin. M and Cw^ unite before tip of wing Chrysoleon Bks. In the forewing, Cu„ and lA unite before margin. M and Cuj run separately into the margin of the wing. ... 4. 4. Legs rather stout. In the forewing, C forks at the origin of radial sector Gymnocnemia^cliu. Legs long and slender. In the forewing, C forks much beyond origin of radial sector, always at origin of first branch of ladial sector Froggattisca mihi. 5. Basal joint of tarsi longer than apical one. In the forewing, Cu^ runs parallel to Cui for some distance 6. Basal joint of tarsi shorter than apical one. In the forewing, Cuo does not run parallel to Cu^ 7. 6. Some of the crossveins in the costal area of the forewing united (two series of cells); the bent branches of radial sector in forewing form, or tend to form, a straight line through the apical part of wing. In hindwing, several rows of cells between Cu^ and hind margin.... Protoplfctron Gerst.
