description ,,Ociili.s non lineatis", but I think he had not seen the 

 species alive, at all events certainly not those sent to liim by Stæger, 

 so that he only gives this character after Meigen. Now I found in 

 the collection in our Museum sonie speciinens, all small, labelled 

 6'. nitidus Meig, and these are certainly collected by Stæger and 

 specifically identical with those sent to Zetterstedt. As I could find 

 no character separating them from iridatus, I soaked them all in order 

 to see the eye-coloration, and it then proved that they all had greenish 

 eyes with an iridescent band iying far above quite as in indatus. There 

 is thus no doubt, that they are all small specimens of this species. 

 According to this I think that nitidus is only a synonym to iridafus, 

 and that Meigen has been niislead with regard to the eye-coloration ; 

 it must be borne in mind, that the band may disappear very soon 

 after the death of the fly; at all events it is certain that all known 

 Danish specimens, also those mentioned by Zetterstedt, are only small 

 specimens of indatus. 



S. iridatiis is as common as cuprarivs and occurs together with 

 it in the same localities and during the same period of the year. 



Geographical distribution: — Europe down to Italy, but it seems 

 in several piaces less common and less distributed than ciiprarius ; 

 towards north it goes to northern Scandinavia.

Male. Eyes greenish, unicolorous; the anterior ocellus nearer to 

 the hinder pair than in the other species. Front metallic green, rather 

 broad, especially downwards; two small, white spots above the antennæ 

 whicli, on account of the broad front, are widely separated in the 

 middle. Antennæ black. Thorax golden green, distinctly yellow 

 pubescent. Abdomen metallic greenish at the base, towards the apex 

 more copper-coloured. Venter black, slightly metallic. Abdomen yellow 

 haired. Legs yellowish or brownish yellow; femora dark brown or 

 blackish, except at the tips; the anterior tibiæ somewhat darkened 

 towards the tips and the ends of the tarsi darkened. Femora finely 

 pubescent, tibiæ and tarsi short and densely yellow haired. Wings 

 distinctly fumigated with blackish brown veins; stigma only a little 

 more fumigated. Halteres yellowish. 



Female. Eyes greenish with an iridescent band Iying above the 

 middle in the upper part of the eye. Front black, very broad with
