Having recently studied a large collection of Myiodaria from the Fiji Islands, and having received, through the courtesy of Dr. P. A. Buxton, a number of species from Samoa and other South Pacific Islands, I am able to make a revision of the Calliphoridae now before me, and to describe some new forms. I have also taken into consideration the specimens from New Zealand and from Eastern Australia in my collection, as well as the forms recently described by Aldrich, Hardy, Malloch, Patton and Surcouf, together with the taxonomic changes proposed by Senior-White, Shannon and Townsend.

It seems that some species, probably those more closely associated with man, are widely spread through the Pacific Islands ; while several others seem to be very localised.
