The Australian Sheep Fly in Hawaii.

[Presented by O. H. Swezey.] 



I was surprised to learn that the screw-worm fly that I 

 bred in such abundance from dead cat and rat, before leaving- 

 Hawaii, is the common sheep-fly of Australia. Froggatt* calls 

 it Calliphora ritfi fades, but it should be placed in the genus 

 Chrysomyia. 



I collected this species in Fiji in 1913; and found it very 

 abundant in Brisbane, during June of this year. At the pres- 

 ent time (August, 1917) I am breeding these flies abundantly 

 from dead animals at Gordonvale. This species was bred by 

 Terry in Hawaii, in 1905, and four of his specimens are in 

 the collection of the Experiment Station, H. S. P. A., but bear 

 no name. 



The species is of tremendous importance in Australia, 

 where it has taken to living sheep, after breeding for many 

 years in the dead carcasses — just as our Chrysomyia dux did 

 in Hawaii. 



The development of the species is very rapid as my Hawaii- 

 an notes would indicate. An animal exposed on the 16th of 

 July; larvae hatching on the morning of the I7th and fully 

 developed on the 20th ready to enter soil ; pupal stage about
