This species is indigenous to Asia, and it has evidently 
been imported into the western part of the United States in 
comparatively recent years. Dr. D. C. Graham, for whom the 
species was named, has supplied the National Museum with a 
long series of specimens from Szechuen Province, China. It is 
evidently a common species in Asia, and it has become a rather 
common form within the past few years in the vicinity of Sacra- 
mento, Calif. 
Normally the largest of the North American species related 
to the genus Calliphora; with the general coloring and habitus 
of vonmutoria.
