V. — Report of the Eugbt School Natural History Society for 

 the Year 1916. 1917. 



GEOLOGY still maintains an excellent position among the various 

 sections of this Society. In the present Report (pp. 98-100) 

 it is noted that visits were made to Napton Quarry, and that fossils 

 were collected from the Capricornus zone of the Lower Lias. Some 

 pits at Nuneaton are also referred to as having yielded Carboniferous 

 ferns and Catamites, while marlstone fossils were obtained from 

 Fawsley Park, near Badby. Doubtless the better part of such 

 material will find its way into the School Museum, which already 

 contains good palaeontological specimens, those of local interest being 

 perhaps of greatest importance. This Report also informs us that 

 the Rugby School Natural History Society has now been in existence 

 for fifty years, a fact on which we venture to offer our congratulations. 



YI. — New Tertiary Inskcts. By T. W. A. Cockerell. Proc. 

 United States National Museum, vol. lii, pp. 873-84, pi. xxxi, 

 1917. 



TJ1HE material described in this paper was obtained from the Eocene 

 J_ (Oil Shales) of "Western Colorado, from the Miocene beds of 

 Florissant, Colorado, and from the Oligocene formation of Gurnet 

 Bay, Isle of Wight, belonging to the British Museum, although 

 originally in the collection of the late Rev. P. B. Brodie. The new 

 British forms described include : — Diptera : Riphidia brodiei, 

 Mongoma cruciferella, Tipula gardneri, Bibio gurnetensis, B. oligocenus, 

 Mesomyites (new genus) concinnus, Protoscinis (new "genus) perparvus. 

 Thysanoptera : JEohihrips brodiei. Neuroptera : Sisyra (?) disrupta. 

 The new American species determined include: — Diptera: Plecia 

 Winchester i, from the Eocene (OilShales) of Colorado, and P. explanata, 

 from the Florissant deposits, the latter formation having also yielded 

 Acreotricliites (new genus) scopulicomis, Rhamphomyia hypolitha, 

 Urortalis (new genus) caudatus, Melieria atavina, and Anthomyia 

 persepulta. Hymenoptera : Tceniurites (new genus) fortis and 

 Heriades prisms, both from the Florissant Miocene. 



YII. — South Australia. Annual Report of the Government 

 Geologist [L. Keith Ward] for 1915. Fol. ; pp. 18, with 

 maps and tables. Adelaide, 1916. 



fllHIS report contains information on metallurgical subjects, water 

 1 supplies, mineral resources, building stones, etc. A very 

 important item of the year's work concerns the discovery of precious 

 opal at Stuart's Range at a place situated 81 miles west by south of 

 Anna Creek Railway Station. The specimens are stated to have 

 been evidently derived from the Desert Sandstone formation which 

 extends across Western Queensland and New South Wales into the 

 northern portion of South Australia. Yaluable notes on the building 

 stones, which are regarded as Palaeozoic and Tertiary, are set out in 

 a series of tables at the end of the Report.
