Kandari (Celebes) taken April 1874, but is hardly positive as to 

 identity. Walker describes a perfect specimen of what he takes to 

 be the male, but selects the headless female as the type !

One example ; sex ? Hong Kong. A large handsome species, 

 I took a 'b 2 «w cop. and a separate ? at Yokohama, 21st to 26th 

 May 1906, thus fixing the sexes and species. Schiner queried the 

 sex of his type specimen. I think it was a h , because he men- 

 tions " front broad behind" and this is apparently the case (but 

 not really so, proportionately) in this sex, owing to the eyes almost 

 touching in front just above the frontal raised triangle. The 

 front in the ? is slightly but distinctly wider. In the 2 taken in 

 cop., the white 2nd translucent abdominal segment is much ob- 

 scured. Van der Wulp mentions the occurrence of the species in 

 Japan, from which land it also figures in the recent Catalogue of 

 Palaearctic Diptera.

By Van der Wulp's remark referring to his apicalis " close to 

 rufescens V. W." I have presumed this species to be of the same size, 

 and therefore enter it in my table as 15 to 16 mm.

There are six more or less closely allied species in this group, 

 and I have had some difficulty in understanding them All seem 

 distinguished from all other species in the genus by the basal half 

 of the wing being brightly yellow, and the remaining half blackish — 

 commencing at or just beyond the discal cell to the tip of the wing. 

 Two species (aurifer Wlk., and leoninus R.) are said to have the disc 

 of the thorax ferruginous, that is, darker than the general reddish 

 yellow colour of the whole body — the former bearing, in addition,
