42 REVISION 01^ AUSTRALIAN LEPIDOPTERA. By A. J. Turner, M.D., F.E.S. Under this heading I hope to publish a series of papers similar to the present, not taking the different families in any definite order, but as time and opportunity permit. In so doing I must necessaril}' be largely dependent for my material on others, and in the preparation of the present instalment I must acknowledge my indebtedness to Messrs. F. P. Dodd, of ToNvnsville, R. Illidge and TI. Tr3'on, of Brisbane, G. Lyell, of Gisborne, and 0. Lower, of Adelaide, who have presented or lent me specimens for des-cription. Fam. NOTODONTID^. Head usually hairy. Tongue sometimes weak or absent. Maxillary palpi obsolete. Thorax hairy beneath. Femora hairy. Posterior tibise usually with two, sometimes with one, pair of spurs. Anterior tibise usually wdth a groove bare of scales on under surface. Forewings with vein lb furcate at base, Ic absent, 5 from middle or above middle of cell, 7, 8, 9 stalked, 10 out of 8 + 9 or connected with 8 4-9 to form an areole, 1 1 free. Hind-wings with two internal veins, 3 and 4 approximated at base, b-usually imperfect from middle of cell, rarely absent, 6 and 7 usually stalked, 8 closely approximated to cell as far as middle, usually to near end of cell, sometimes connected with cell by a bar. This is a very natural famil}-. Superficially some of its members resemble the Noctuidcf^., but there is not really any close relation-ship. The two families may always be distinguished l)y the origin of vein 5 of the forewings. On the other hand, the Notodontidit' are closely allied to the more primitive forms of the
