complete the Coleoptera. — 2) Descriptions of new Lepidoptera. By E. Mey- 

 rick, B.A., F.E.S. In this paper descriptions are given of sixteen new 

 species of Australian Lepidoptera belonging to fourteen genera, of which six 

 are new. Among them is Thalpochares coccophaga^ of which, at the December 

 Meeting of the Society, Mr. Masters exhibited specimens of both moths 

 and larvae, and called attention to the singular habits of the latter, which 

 feed on a species of Coccus infesting a Macrozamia, living concealed in a 

 cocoon-like shelter formed of the exuvije of the Coccus, and finally pupating 

 therein. — 3) and 4) Botanical. — 5) On a probably new species of Tree- 

 Kangaroo from North Queensland. By C. W. De Vis, M.A. — The name 

 of Deiulrolagus Bennettianus is proposed for a supposed new species of Tree- 

 Kangaroo of which one specimen was obtained in the Daintree River District. 

 It lived in captivity for a time, but was subsequently killed, and its skin, 

 unfortunately deprived of everything else but the bones of the hands and 

 feet, was subsequently submitted to Mr. De Vis, who after comparing it 

 with two skins of Dendrolagus Lumholtzi, Collett, has no doubt that it is 

 distinct from its compatriot, and is more nearly allied to D. Dorianus, Ramsay. 

 As full a description as is possible under the circumstances, is given in the 

 paper. — The following note was read for Mr. John Mitchell, in cor- 

 rection of some remarks made in our Proceedings for June, in reference to 

 some fossils from Bowning exhibited by him. »The late Rev. W. Clarke, 

 F.R.S., had declared the geological formation of Bowning to be of Devonian 

 age, having been led to this conclusion chiefly by the occurrence of Calceola 

 sandalina, which European geologists recognise as a typical Devonian fossil. 

 But above the series of rocks from which this fossil has been obtained, as 

 well as in conjuction with it, I have collected a number of Trilobites that 

 are typical of the Upper Silurian, particularly several species of Acidasjns 

 (a genus not hitherto recorded from Devonian strata). Harpes tmgula, Siauro- 

 cephalus Murchismiii, Encrinurus punctatus, several species of Calymene and 

 others, all Silurian types, whereas from the remarks referred to it would 

 appear that these fossils were from beds underlying the supposed Devonian 

 strata. Hence from the evidence furnished by these fossils I am of the 

 opinion that the formation is decidedly Upper Silurian. I may also add that 

 in so far as it applies to the geology of Yass, the error was pointed out some 

 time ago by Mr. Jenkins, L.S.« — Dr. Ramsay exhibited a specimen of 

 an apparently new Species of Monacanthus, presented to the Australian Mu- 

 seum by Mr. G. R. Eastway. He also exhibited ^eggs of P^i7o«oj7/ync//Ms 

 violaceus, and Rhynchœa australis, and read the following notes on the subject ; 

 — (1) Ptilonorhynchus violaceus, Vieill. [P. holosericeus , Kuhl.) »In the Pro- 

 ceedings of the Zoological Society of London for 1875, March 2nd, p. 1 12, 

 when I first described the egg of this species, I laid stress on the peculiar 

 short icavij and irregular markings, drawing attention to the somewhat similar 

 characters exhibited on the eggs of Chlamydodera maculata ; at that time I 

 had only two perfect specimens from nests taken in the Wollongong district. 

 Since then however, I have received two well authenticated sets, which show 

 that the eggs previously described were not of the normal form, hence the 

 necessity for describing the most common variety, in which irregular blotches 

 and spots, form the characteristic markings. The eggs vary in proportionate 

 length, but are usually long ovals, seldom even slightly swollen towards the 

 thicker end ; the ground color is of a rich cream or light stone color, spotted
