NEW SPECIES OF CORYLOPHIDAE (COLEOPTERA). By Cedeic Deane, A.M.I.E.Aust. (Seven Text-figures). [Read 26th October, 1932.] There has been a scarcity of information regarding the Australian Corylophidae; Lea's paper (Pboc. Lixx. Soc. N.S.W., Vol. x, Ser. 2, 1895) constitutes the bulk of the literature. The drawings herewith are, I believe, the first to appear of the Australian members of the group. Matthews' monograph of the world's representatives should also be consulted. Help has been afforded by auxiliary microscope equipment kindly put at my disposal by Mr. H. P. Colwell, M.I.E.Aust., as a result of which I have been able definitely to establish the tarsal formula as 3-4-4 for the new species of Se7-icoclerus. I must mention here my gratitude to Mr. John Clark, F.L.S., Mr. F. E. Wilson, F.E.S., and Mr. C. Oke, of Melbourne, for assistance in the loan of literature, and especially to Mr. Clark and Mr. Wilson for their generous advice and material, which have enabled me to arrive at my conclusions. Seiucodeeus. In general appearance, both on dorsal and ventral surfaces, the new species herein proposed under Se^'icoderus agree sufficiently with some of the Australian species previously described under this genus to warrant their being included provisionally with them. Owing to the difference between the forms inhabiting one part of the world from those of another, I have thought it advisable to give for the new species in common those characters which may be considered to be of generic status. These are as follows: Generic Characters. — Ovate, convex, somewhat robust, margin entire, widest across base of pronotum. Head completely concealed from above by hood of pronotum; small, somewhat rostrate; rostrum broad, blunt, subquadrate. Eyes large, rather receding, coarsely faceted, not widely separated. Antennae of medium length, incrassate, clavate; scape and pedicel large, scape larger than pedicel, segments 3 to 7 small, 8 to 10 large, forming the club. Pronotum rather large, broad at base, forming acute posterior angles; evenly rounded in front from side to side; entirely without anterior angles. Scutellum small, shield-shaped. Elytra wider at base than apex, almost covering abdomen. Pygidium widely rounded at apex. Prosternum strongly arcuately concave posteriorly. Mesosternum very short, receding. Metasternum large, not attaining sides; episterna and epimera distinct, the former long, curved, tapering posteriorly; hind margin convex at centre, concave at outer thirds. Abdomen with six visible ventral segments, basal one rather long, remainder evenly spaced; pygidium rounded, not
