Ix the present paper, further descriptions of Australian andtl'he
Tasnranian speciesof the genus Moloptltilus are given.
majority of ttrese species belong to the typical subgroup of
tlrc gracilis group, the type-lbrn-r of which (gracilis, Sktise)
was figured in Part XXXIII. of this series of papers (Ann.
& Mag. Nat. Hist. ser.9, vol. xix. p. 17 ; 1927). In this subgroup, the male hypopygium is characterized by the urtusualdevelopment of the individual lobes of the basistyle, thedorsal, ventral, and mesal lobes being variously developed,
tire trvo clististvleslvirg in the notch formed by these lobes.
