{annulipes Thoms. , Eugenie Reise, 461.) 



h East India. Type in Royal Museum, Copenhagen. 



Osten Sacken records a h from Java, and I took one 'b 

 at Bareilly, ist September 1905, and if I have determined the 2 

 rightly I have taken 3 specimens, respectively at Mussoorie, June 

 26 ; Meerut, July (13 to 19) ; and Lucknow, August 8 ; all during 

 1905. From Papua Van der Wulp records 2 'b 'b i $ . 



M. bipars Wlk., 1861. 



(Chrysomyia) Pr. Linn, So., v, 273. 



'b Batjan. Walker says allied to Sargus rcdhibens, but I 

 fail to see where. 



M. affinis Weid. 



(Sargus) Analec. Entom., 31.

M. gemma Big., 1879. 



Ann. So. Ent. Fr. (1879), 231. 



$ Ceylon. Bigot Collection. Bigot emphasizes the very broad 

 front in this species, and speaks of the middle femora and tibiae 

 being indistinctly brown-ringed, yet I would not be surprised to 

 find it only the ? of flaviventris Wied. 



M. calopus Big. 



I $ Margherita (Assam). I cannot trace the reference. (Inci- 

 dentally I may add that Bigot described a Chrysonotus calopus 

 5 in 1879 from Natal, but this is a different species.) Type in In- 

 dian Museum Collection. It is certainly a very distinct species. 



In addition to the species mentioned I possess 3 specimens 

 taken by myself at Mussoorie from Jtme 18 to 26, 1905, in which 

 the last antennal joint is entirely and quite black, the species other-
