NOTES AND EXHIBITS. 



Mr. Fred Turner exhibited and offered observations on a specimen of Lolium 

 iemulentum Linn., wliieh he bad received for determination from Mr. R. Baird, 

 Multagoona, Darling River, vho had never hitherto seen it growing in the dis- 

 trict. The seeds of this exotic gi'ass are considered injurious, and if eaten are 

 said to produce drowsiness, lieadaehe, and vertigo. According to Sir J. D. 

 Hooker and the Revd. Canon Tristram, "this species is identical with the 'Tares' 

 of Scripture, and is one of the worst weeds in the wheat crops of Palestine, and 

 the only grass with a poisonous seed." 



Mr. W. W. Froggatt exhibited specimens of the Bag Shelter or Boree 

 !Moth. Teara contraria, showing the masses of eggs covered with the down off the 

 tips of their bodies. One of the egg masses contained a number of eggs of a 

 parasitic moth, the larvae of which feed upon the eggs of the Boree Moth and 

 pupate under the cover of the egg down. The larvae of this Bag Shelter Moth 

 ever\- year strip the foliage from thousands of Boree trees, Acacia pendula, one 

 of the most valuable fodder trees in Australia. 



Mr. G. A. AYaterhouse exhibited Tlsi/ilioiie rawiisleiii c? and T. ahenna 5 

 which he had paired, together with 3 c? and 2 $ obtained from this cross and 

 also two small families obtained by pairing these first generation specimens. One 

 family consisted of 3 c?. 1 $ , and the other of 1 c?, 2 ?. Also four specimens of 

 the iirst generation obtained by crossing T. abeo)ia c? with T. ravrunleyi ?. Also 

 Heteront/mpha mirifica and H. paradelplia reared from larvae, together with dead 

 pupae of both species. 



Mr. H. J. Carter exhibited (i) specimens of eacli of the six Australian 

 genera of Chalcophorinae (Bupresticlne). These six genera were at an earlier 

 period all classed as Chalcoplinra though they are clearly differentiated in modem 

 work; (ii.) specimens of three closely allied CiipTiogastra. concerning two of 

 which there is some confusion in Kerreman's "Monographic": (iii.) Ci/rioides 

 ser-spilota Carter recently collected by 'Sir. H. W. Brown on the .Tohnstonc 

 River, Q. ; (iv.) an example of a new genus taken by Dr. E. W. Ferguson at 

 Fort Macquaric and (v.) a new species of Stigmodem from the Blue Mts.

 in rocks of Permo-Carboniferous age from Three-mile Creek, on the Bowen 

 Coalfield. Queensland. 



Mr. .J. J. Fletcher exhibited specimens of Persnoiiin hicida R.Br., from 

 the Lane Cove district, being portions of the only two plants, both solitary, he
