doptera, with descriptions of new species. By T. P. Lucas, M.R.C.S.E., 

 L.S.A., and L.E..C.P., Ed. About forty species referable to fourteen families 

 are proposed as new, and striking varieties of four species already known 

 are described. — 3) On the identity of Brnnteus Partschi, de Kon., (non 

 Barrande), from the Upper Silurian Rocks of N. S.W. By R. Etheridge, 

 junr., and John Mitchell. From a knowledge of its pygidium only, Pro- 

 fessor de Koninck identified a trilobite among the Australian fossils sub- 

 mitted to him and described in his »Recherches sur les Fossiles Paléozoïques 

 de la Nouvelle Galles du Sud« as Bronteus Partschi. Mr. Jenkins in his second 

 paper »On the Geology of Yass Plains« (P.L.S.N.S.W. III., p. 217) refers 

 to specimens of the same species as Bronteus sp., which he considers related 

 to, if not identical with, B. Partschi. From the examination of additional 

 material from the Bowning series, of the same age as the Hume beds of 

 Jenkins, the authors have come to the conclusion that the Australian trilo- 

 bite in question is not to be identified with Barrande's B. Partschi, and they 

 accordingly separate it as a new species under the name B. Jenkinsi. — 

 4) Notes on the Plumage of the adult males in certain species of Malurus. 

 By A. J. North, F.L.S. The statement of the late Mr. Gould that the gay 

 attire of the members of the genus Malurus »is only assumed during the pair- 

 ing season, and is retained for a very short period^, after which the sexes are 

 alike in colouring (»Handbook to the Birds of Australia«, I., 317)« is criti- 

 cised, and shown to be incorrect, since full-plumaged males, more parti- 

 cularly in the section of the genus in which blue predominates, are to be met 

 with all the year round. — Mr. Froggatt exhibited some larvae of an un- 

 determined species of saw-fly, received from Mr. French, which is destroying 

 the tanning wattle. Acacia decurrens, about Melbourne. They not only destroy 

 the leaves, but also gnaw the bark, soon killing the trees. The pest was 

 locally known as »Fire-blight«, until Mr. French, the Government Entomo- 

 logist of Victoria, discovered and recognised the small grubs. — Mr. Flet- 

 cher showed specimens of a small worm (family lubißcidae) which like the 

 remarkable tramatode [Temnocephala) described by Dr. Haswell lives as a 

 commensal upon Astacopsis serratus. — Some discussion then took place as 

 to the meaning of the now universally adopted term »kangaroo«, namely 

 whether, as has recently been reported, in the dialect of the blacks of the 

 Endeavour River the word signified »I don't know« and was so used in answer 

 to the queries of Captain Cook's party, or whether as Cook supposed it really 

 was the name of the animal in use among the aborigines of the locality.
