ARKIV FÖR ZOOLOGI. BAND 11. N:o 26. Besults of Dr. E. Mjöberg's Swedish Scientiflc Expeditions to Australia 1910—1913. 18. Neuroptera and Mecoptera by P. ESBBN-PETERSBN. With 3 Plates and 15 Figures in the Text. Communicated May 8*^ 1918 by Chr. Aurivillius and Y. Sjöstedt. It has given me great pleasure to work out the material from the expeditions of Dr. E. Mjöberg. The Australian Neuropterous fauna contains so many archaic and peculiar forms, that their study will always bring an enrichment of knowledge. My best thanks are due to Prof. Dr. Yngve Sjöstedt and Dr. E. Mjöberg for the opportunity of looking throngh the interesting material, but I am further very much indebted to Prof. L. Kruger, Stettin, and I wish to bring him my best thanks here. His publications concerning systematical Neuropterology have opened my eyes for the true and cor-rect apprehension of the nervature of the wings in the Neuroptera, and his accurate and careful method of working has been exceedingly impulsive to me.
