plants and grasses, which had been received by him for identifi- 

 cation and report as to their economic value for stock-feed. They 

 were : Andropogoii sericeus R. Br., var. jjo/ystachyns; AntJnstiria 

 frondosa R. Mv ; Ceniothnca lappacea Desv., probably a new 

 record for this species; Chloris scariosa F.v M., said to 1)6 the 

 most, beautiful grass in the north; Eriachne ciliata R Br.; E 

 ■pallescens R. Br., probably a new record for this species; E squar- 

 rosa R. Br.; Heterachne Brownii Benth.; Paidcum argenteum 

 R. Br.; Fanicum Peiiviri Trin., (in the Flora Austr., vii., p.481, 

 this gia.ss isqueried as a variety of Paiiicum foliosum R. Br., but 

 Ttinius' name deserves to be restored to this plant as it appeais 

 to be a good species) ; Panic^im trichoides Sw.; Pollinia articu- 

 lata Tiin.; Rotthoellia excdtata Linn ; and Sorghum intrans F.v.M. 



Mr. A. A. Hamilton communicated a Note on the correct 

 identification of a grass exhibited at the INIeeting in May, under 

 tlie name of Panicum glahriivi Gaud., but which, he contended, 

 was Digitaria didactyla Willd. As the specimens in question

 not at present available for comparison, the point at issue remains

Ml-. Cheel exhibited specimens of Digitaria didactyla Willd., 

 [Pimicum didactylum Ivunth) to be found plentifully at Parsley 

 Bay. The specimens were determined by Dr. Otto Stapf, who 

 says that the species was collected by F. W. Sieber at Port Jack- 

 son, or in the neighbourhood, as long ago as 1823, and distributed 

 by him in his "Agrostotheca," No.72. It has since been found 

 on one of the lawns in the Botanical Gardens(E. Cheel; January, 

 1903); Watson's Bay(0. A. White; October, 1910); and at Bondi 

 (W. F. Blakely; November, 1910). 



Dr. J. B. Cleland exhibited specimens of adults and larvte of 

 Culex austrcdis Erichs., (C crucians Walk.). These had been 

 identified, through Mr. E. E. Austen, by Mr. Edwards, of the 

 British Museum. The larvae, from which some of the adults were 

 hatched out, were found in shallow pools of water near tlie sum- 

 mit of Mount Kosciusko at a height of 6,000 feet in December, 

 1910. The pools were formed by the melting of patches of snow,
