The present paper completes the study of the Ipswich Upper Triassie fossils 

 sent to me by Mr. B. Dunstan, Chief Government Geologist of Queensland, with 

 the sole exception of the Coleoptera, which Mr. Dunstan himself is dealing with. 

 In it no less than twenty species are dealt with, of which sixteen are described 

 as new, while ten new genera are proposed for their reception. The species 

 dealt with belong to the Orders Protorthoptera, Orthoptera, Odonata, Hemiptera 

 (both Homoptera and Heteroptera) and Neuroptera Planipennia. A number of 

 the fossils are shown enlarged on Plates li.-liii., which have been reproduced from 

 photographs taken by Mr. W, C. Davies, Curator of the Cawthron Institute, to 

 whom my best thanks are due. I also desire to thank Mr. F. Muir, the well 

 known Homopterist of Honolulu, for valuable criticisms of my former publica- 

 tions on fossil Homoptera, as a result of which I have attempted some regroup- 

 ing of the families represented in the Upper Trias. 



Order PROTORTHOPTERA. 



Family MESORTHOPTERIDAE. 



Mesorthopteron locustoides, Tillyard, Mesozoic and Tertiary Insects of 

 Queensland and N.S.W., Queensland Geol. Survey, Publ. No. 253, 1916, p. 14, 

 Plate 2, figs. 3—6. 



The types of this species are Specimens No. 5a and 5b in the Queensland 

 Geol. Survey Collection at Brisbane. The fragment 5c, though originally figured 

 (i.e., Plate 1, fig. 4) as belonging to this species, can now be proved not to 

 belong to it at all. The wing shown on Plate 1, fig. 5 of the same paper (Speci- 

 men No. 4), which was originally indicated as doubtfully belonging to this 

 species, has now been shown, by further study and comparison with other 

 fossils, to be the somewhat badly preserved tegmen of a Homopteron, Mesocixiodes 

 hrachyclada, n.sp., described in this paper. 



Since the type was described, a number of fragments of this species have 

 been discovered at Ipswich, together with one more complete specimen showing
