175 MESOZOIC INSECTS OF QUEENSLAND. No.l. Planipennia, Trichoptera, and the new Order Protomecoptera. By R J. TiLLYARD, M.A., B.Sc, F.L.S., F.E.S., Linnkan Maclkay Fellow of the Society in Zoology. (Plates vii.-ix., and seven Text-figs.) Introduction. The present paper deals with a portion of the ver}' interesting fossil insects recently obtained from the Ipswich Beds b)' Mr. B. Dunstan, Chief Government Geologist of Queensland, to whom I am much indebted for the opportunity of studying such fine and, in many respects, unique material. This collection may be looked upon as the third collection of insect fossils made at Ipswich. The first, or Simmonds Collection, was made in 1890 by Mr. T. H. Simmonds, of Brisbane, and the specimens were described by Etheridge and Olliff in the same year.* In 1909, Mr. Dunstan made a second collection of insects from the same locality. These were sent to me for study in 1913, together with some fossil insects from other beds in Queensland and New South Wales. All these were dealt with in a paper published last year by the Queensland Geological Survey. f In this paper, *The Mesozoie and Tertiary Insects of New South Wales [and Queens-land]. Geol.
