lyOC— China. Type in British Museum. 



N .B. — I retain this species as Walker quotes merely ' ' China/ ' 

 and it is advisable to retain the species from South China, at least 

 for the present, in the Oriental lists, but I do not know of the 

 species occurring in any truly Oriental locality.

]S[.B. — This species must be allied to Macquart's australis, 

 described from Port Jackson, and at first I thought it was that 

 species. A closer examination seems to point to its being distinct. 

 Macquart's species was described in his Dip. Ex., ii, 396, pi. xiii, 

 2 (1840), the plate showing a full insect and the head in profile.
