I. PASSEROMYIA AND ORNITHOMUSCA. 
In 1851 Macquart described two new species of the Dipterous genus Cyrtoneura 
from Tasmania, under the names of Cyrt. longicornis and Cyrt. analis, both 
species being very different from all others of the same genus in having hairy 
eyes and the first species also owing to its very long third antennal joint. 
They were never recorded by subsequent writers until 1916 when Tylei 
Townsend describing his new Australian genus Ornithomusca expressed doubts 
as to the relationship of the above mentioned Macquart’s species to his own 
genus (p. 145). In 1919 the late Prof. Stein in his Catalogue of the Anthomyidae 
'of the World (p. Ill) recorded these two species, showing however that they 
do not belong to the genus Muscina (which now comprises several species of 
the old genus Cyrtoneura) and that they cannot be placed in any known genus 
of Anthomyidae. 
I have recently received from Mr E. W. Ferguson two specimens of a 
fly, one bred at Sydney, N.S.W., from a larva found in a nestling of the New 
Holland Honeyeater, the other caught in the open. Both these specimens 
I have recognised as belonging to the species Cyrtoneura longicornis Macquart. 
On the other hand, the type specimen of Ornithomusca victoria Tyler Town¬ 
send has been also found in nests of Pardalotus sp. and according to the 
description differ from longicornis only in the colour of the dust of the head, 
palpi, calypters, the base of the wings and the hairs of the body so that it is
