NOTES AND EXHIBITS. 



Dr. H. G. Chapman exhibited a series of paintings by Miss Rosa Fiveash 

 of flowers of variants of Clianthus Dampieri collected by Dr. O. M. Moulden 

 in the neighbourhood of Broken Hill. Dr. Moulden had collected a number of 

 these variants and removed them to an area within the town, and was engaged 

 in a study of the plants. 



Dr. R. J. Tillyard exhibited larvae, pupae and imagines of two new 

 species of Blepharoceridae, one taken at Mt. Kosciusko, the other at Wentworth 

 Falls. Except for a single specimen taken at Kuranda, this family has not 

 been recorded from Australia, and has been generally supposed to be absent 

 from the temperate parts. Tlie family is best represented in North and South 

 America and in New Zealand. The whole life-history is passed on or near the 

 face of a waterfall, even the imagines clinging close to the rushing water or 

 fl>-ing in the spray. The species found at Kosciusko is the largest and most 

 archaic yet discovered. 



Mr. W. F. Blakely exhibited from the National Herbarium, the following 

 unrecorded introduced weeds for this State: (1) Chenopodium vulvaria L., 

 "Stinking Goosefoot," (Yass district, per Chief Inspector of Stock), a common 

 weed in most countries, in fields and waste places; "it is widespread in Victoria," 

 Ewart (Weeds and Poi. PI., 75). (2) Sit<ymbrmm Sophio L.. "Flixweed or 

 Fluxweed," (Ando, Bombala District, Stock Inspector Kenny), one of the 

 Hedge Mustards, very widely distributed throughout Europe and Asia; like 

 other allied species there is a danger of it becoming a menace to agriculture in 

 this country as the conditions are favourable to its development. It is a new 

 weed for the Commonwealth. (3) Centaurea picris Pall. (Acroptilon picris), 

 "Hard Heads." This spineless species, a native of the Caspian Region, ha."? 

 recently appeared in the Henty district. Professor Ewart records it for Vic- 

 toria {vide Vic. Nat., xxiii.. 1907. 184).
