NOTES .\XD EXHIBIT.S. 



Dr. E. AV. Ferguson exhibited specimens of the imago and larvae of <*> 

 muscid tiy belonging to an undetermined genus. The imago was bred from a 

 pupa taken in the nest of a Leatherhead by Messrs. W. G. and R. C. Harvey, 

 of Mackay, (Queensland. The larvae live on the nestling birds, and when 

 mature conceal themselves in the nest and pupate. Out of twenty pupae ob- 

 tained by Messrs. Harvey, only one hatched out, the others being parasitised by 

 a chaleid wa-sp, a pair of which were also exhibited. Mr. P. H. Gilbert, of 

 Lakemba, Sydney, has found what appears to be the same species on nestling 

 birds (New Holland Honeyeater). 



Mr. E. Cheel exhil)ited some very interesting specimens of a rare lichen 

 collected on Mount Kosciusko by Miss A. V. Duthie. 



The only specimens previously collected, so far as can be ascertained at pre- 

 sent, are in a solitary collection by Rev. F. R. M. Wilson, found on earthy 

 rock on Mount Hotham, Victoria, in January, 1890. The specimen is labelled 

 Ihifnurea madreporiformis (Wulf.) Ach. (AA'ilson No. 1157, in National Her- 

 barium, Sydney). It seems to have close affinities with Dactylina artica (Hook.) 

 Nyl., and further investigation is needed to settle the generic position, as no 

 apothecia are present in either the Mount Hotham or Mount Kosciusko specimens. 

 Unfortunately there are no specimens of the above-mentioned genera (recorded 

 from Arctic Regions) available for comparison.
