of both species, 146 miles further north than the exhibitor's pre- 

 vious record of both breeding on Tom Thumb Islands, off WoUon- 

 gong (These Proceedings, 1909, p.589). 



Mr. Froggatt exhibited specimens of a curious fly (Oncodes 

 fumatus Erichs.), which deposited its eggs in such numbers, upon 

 the tips of apple-twigs in Mr. Richardson's orchard at Galston, 

 that tlie buds died back and the twigs became quite black. 

 Hundreds of the minute larvfe subsequently batched out; of these, 

 examples were exhibited. They are ISsegmented maggots, dark 

 brown in colour, and covered with stout hairs. The head-segment 

 is elongate-oval, smaller than the thoracic segments, which, 

 merging into the abdominal segments, are broadly rounded to the 

 anal segment. They progress by pressing the anal segment on 

 the bottom of the box, and curving tlie body round like a bow, 

 when they jump like cheese-mites. Nothing had been previouslj' 

 recorded of the habits of Australian species of this small but 

 cosmopolitan family of the Diptera; but, in America, two allied 

 species are, in the larval state, parasitic upon spiders; the larva 

 attaching itself to the body of the spider, and then devouring it. 

 Another fine dipterous species, Pterodontia mellii Erichs., was also 

 exhibited; this is usually found on tree-trunks or stumps, so that 

 it is probably parasitic upon large spiders found under the dead 

 bark. Specimens of a lai'ge longicorn, Demonsthra helleri Lam., 

 and its larva?, from the Solomon Islands, were also shown. 



Mr. A. R. McCulloch exhibited, by permission of the Curator 

 of the Australian Museum, two fishes wliich were previously 

 unknown in Australian waters — a small shark, Scyliorhinns 

 marmoratus Bennett, which had been taken at Port Darwin, N. 

 Territory, and the other an eel, Echidna zebra Shaw, from 

 Fremantle, W. A. 



Mr. A. A. Hamilton exhibited a series of plants from unrecorded 

 localities, comprising Paiiicum fflabrum Gaud., (syn., F. lineare 

 Krocker, Paspahim amhiguihm. DC); Leura, Blue Mountains; 

 March, 1910(A. A. Hamilton). In the Proceedings of this Society 

 for 1908(p.344) Mr. Fred Turner recorded this Indian grass from
