A short black species, with yellow head and appendages, with black wings, the 

 base and four indentations being hyaline. 



All the bristles are black. Squamulae whitish, haltères light yellow. The hind 

 tibiae seem to be variable in colour, as Loew and Becker describe them as entirely 

 yellow. There is also in some specimens a slight trace of the smaller hyaline indenta- 

 tion of the hind margin of the wings, characteristic of the following species. 



If the above synonymy is right^ as I think, the species is known from Spain, 

 from Teneriffe, from India and Ceylon and from Java and the Nicobar Islands. 

 The collection includes three female specimens from Balugaon, PuriDist., Orissa, 

 i4-xii-o8 (/. Gaunter) {----f^---) , and one caught at light by Mr. Gravely in Diamond 

 Harbour — Calcutta train, 4-xii-io.

Very like the preceding, but distinct in having four (not three) hyaline indentations 

 at the hind margin of the wings. 



The hyaline indentation characteristic of this species is shorter than the others, 

 beginning only at the fifth vein , while the others begin at the fourth or at the third 

 (the apical). The hind tibiae seems to be also variable, from wholly yellow to yellow 

 with blackened base. 



I think that the above synonymy is doubtless correct ; atilia, melaleuca and sexin- 

 cisa are quite certain ; the description of sexmaculata , Macquart, also agrees well, 

 only the figure shows the indentations of the fore border much smaller. Of sanctae- 

 mariae, Bigot says that the antennae are black, but in the coloured figure they are 

 yellow ; the figure shows a hyaline spot at the fore border before the stigma, which is 

 absent in my specimens, which have only a thin hyaline streak at this point. My 

 melania is also the same species, only the antennae are described as darker. 



The species is therefore known from South Africa, from Madagascar and Bour- 

 bon I., from China and from Celebes, Ceram, the Philippines and Formosa. 



In the collection are many specimens from Calcutta collected in the months 

 January, April and November, one from Rajshai, E. Bengal, i — 6-ii-07, by Dr. Annan- 

 dale ; one from Naini Tal, Kumaon, 6000 ft., 5-vi-09. There are also four specimens
