NOTES AND EXHIBITS. 313 



Mr. Maiden sent for exhibition the type specimens of West 

 Australian plants described in Mr. Fitzgerald's paper. 



Dr. R. Greig Smith exhibited a series of gummed fruits, and 

 sections of stems and branches in illustration of his paper. 



Mr. Carne exhibited photographs and a series of specimens of 

 nepheline-pegyrine rocks to illustrate the occurrence of laccolites 

 in the Barigan district, near Mudgee, N.S.W.; and he described 

 in some detail the origin and characteristics of these interesting 

 dome-shaped rock masses — igneous rocks which had intruded the 

 Coal Measures, and uplifted the overlying Hawkesburj^ Sandstone 

 but without reaching the surface at the time, though long after- 

 wards subsequently uncovered by denudation; and he gave parti- 

 culars as to the manner and variable extent to which the seams 

 of coal had been affected by intrusive masses. 



Mr. Palmer showed a nuinbar of specimens obtained during a 

 visit to Gladstone, Queensland, and illustrating the mineral 

 resources of the locality. 



Mr. Waterhouse exhibited (1) representatives of 100 species of 

 Australian Lyccenidce from his own and the Macleay Collections. 



(2) Specimens of Eiischemon rafflesia, MacL, and its pupa, an 

 insect considered by some entomologists to be a butterfly, by 

 others a moth. Its Rhopalocerous characters are hooked, 

 clubbed antennre ; palpi and method of flight as in the llesperidie; 

 larva with a dark hard head ; pupa slightly fastened by the tail 

 and enclosed in a sheath formed by drawing two. leaves together. 

 Its Heterocerous characters are the presence of a frenulum, and 

 its method of resting with wings outstretched (as is the case in 

 the undoubted Ilesperid genera Phoenicops and Netrocovijne). 



(3) A pair (^9) of Telesto monticolce, Olliff, from Walhalla, 

 Victoria, belonging to Mr. G. Lyell. The onl}" previous record is 

 that of two specimens ((J) from Mt. Kosciusko. The female is as 

 yet undescribed.
