ABSTRACT OF PROCEEDINGS. 
XIII. 
Plant Pathologist. He was the first Secretary of the Royal' Society of 
Queensland and took an active part in the scientific life of Brisbane. 
He contributed many papers on natural history largely to Government 
publications and to the Proceedings of this Society. In 1895 Tryon 
visited British New Guinea to collect sugar-cane varieties which were 
imported into Australia. He brought back 66 varieties, including the 
well-known Badila, which is considered to be the best variety of sugar- 
cane ever introduced into Queensland. He was a member of a travelling 
commission appointed in 1912 to visit the many countries where prickly- 
pears were indigenous or naturalised, to investigate means of control 
that might be applied in Australia. A complete list of his publications 
was given in the 4 4 Queensland Agricultural Journal” for August, 1929. 
Miss E. N. Marks exhibited the larva of Aedes (Finlay a) Mocellatus 
(Taylor). The female of this mosquito was described by Taylor in 1914 
(Proc. Linn. Soc. N.S.W., XXXIX., 463) under the name Cidex 
Mocellatus from specimens taken by Drs. Ferguson and Cleland on 
Milson Is., Hawkesbury River, N.S.W. It is referred to as Aedes 
(Finlay a) Mocellatus by Edwards (1924 Bull. Ent. Res. XIV., 381). 
No other references to it have been found. The larva is here recorded 
for the first time. Adult males, also hitherto unrecorded, have been 
bred out from collections of larvae and pupae. The type specimen was 
not available for examination in Sydney in May, 1944, but a male 
specimen bred out November, 1943, from larvae from Mt. Glorious was 
compared in detail with a female from the type locality, 1913, determined 
by F. W. Edwards. There could be no doubt that both belonged to the 
same species. Larvae are found in treeholes in rain forest. Earliest 
specimens in the collection of the University of Queensland are larvae 
from Mt. Glorious, September, 1942, collected by F. A. Perkins, and 
bred adults, October and November, 1942. Larvae were collected from 
the same treehole in October and November, 1943. In July, 1943, this 
hole was dry and leaf mould collected from it was placed in a dish and 
covered with tap water. Four weeks later 4th instar Mocellatus larvae 
were observed. These were separated into a jar, but failed to pupate. 
Three weeks later another series of 4th instar larva was present, and 
from these adult Mocellatus were bred out. Further samples of larvae 
were collected by Lieut. J. L. Wassell from treeholes at Wengen Creek 
and Mt. Mowbullan, Bunya Mts., September, 1944, and individual 
specimens have been bred out from these, so that correlated adults and 
larval and pupal skins are available. In the latest key to larvae of 
Genus Aedes (Lee, 1944, An Atlas of the mosquito larvae of the 
Australasian region) A. Mocellatus would come out with Aedes (Finlay a) 
allooannidatus, but it shows no close affinity to this species. 
Mr. S. T. Blake showed specimens of Polypodium pustulatum, 
Arthropteris Beckleri, and Felicia diversifolia illustrating different 
types of polymorphy in leaves. 
Dr. D. A. Herbert exhibited Cordyceps muscae, a fungus attacking 
Sarcophaga sp., collected by Capt. R. F. Langdon at Port Moresby in 
July, 1944. He also exhibited Cordyceps sp. on the small brown ant, 
Pheidole megacephala , collected under the bark of Eucalyptus tereticornis 
at Southport, and specimens of the same species from Brisbane. 
Dr. W. H. Bryan exhibited a scale model of a soil profile at the 
State Agricultural College, Lawes. The model, which is the work of 
Mr. P. J. Skerman, M.Sc.Agr., is on the scale of 1 inch to 1 foot arfd was
