on to the sphene crystals and have not interfered with their 

 growth. 



The granite in which the sphene crystals occur contains a large 

 amount of hornblende as well as mica. 



Mr. Fletcher showed an interesting specimen of the "Flannel 

 flower" (Actinotus heUantlii, Labill.), forwarded for exhibition by 

 Dr. Woolls about a fortnight ago, a few days before his death, 

 with the following note : " In the ordinary form the involucre 

 consists of about ten tomentose bracts enclosing a dense head of 

 umbels ; but in the accompanying specimen eight heads of flowers, 

 each on pedicels about an inch long and surrounded by about six 

 bracts, have grown out of the common involucre." 



Also five individual flowers of Rhyncospermum jasminoides, 

 Lindl., an Apocynaceous plant from China not uncommon in 

 Sydney gardens, each of which had proved a veritable death-trap 

 to a large indigenous flower-frequenting fly (fam. Tahanidce ?), 

 which in attempting to rifle the flower of its nectar had become 

 inextricably caught by the proboscis. The specimens — only a 

 ])ortion of those noticed — were forwarded by Mr. W. N. Dove, 

 B.A. 



Mr. Maiden showed a specimen of the new species of Acacia 

 from the Goulburn District, allied to A. 2yiibesce7is, described in 

 the paper by Baron von Mueller and himself. 



Mr. Froggatt exhibited the beetles mentioned in his paper ; 

 together with living specimens of the larvae, cocoons, and perfect 

 beetles of a common Passalid [Aulacocychis Kaupi, Mel.) from 

 near Bathurst. Also a series of specimens of the female galls of 

 Brachyscelis duplex^ Schrader, in various stages of growth, on 

 Eucalyptus capitellata from Sutherland. 



Mr. L. Stephenson exhibited specimens of an Orchid, Drakcea 

 Himtiana, F.v.M., recently found by him on the Blue Mts., near 

 Blackheath, the species having been found previously only on 

 Mount Tingiringi, on the southern border of the colony, at an 

 elevation of about 5000 feet.
