SECOND SUPPLEMENT TO ANNOTATED LIST OF BRITISH 

 ANTHOMYIID.E. 



BY R. II. MEADE. 



(^Continued from p. 39fi). 



H. DUBiA, Mde. 

 Since I described this species as new in the first part of my list, I liave found 

 that it has been previously discovered by Professor Mik, of Vienna, and named II. 

 Ooberti; ray name must, therefore, sink into a synonym. 



MTD^A, R. Uesv. 



M. ALLOTALLA, Meig. 



Some years ago Mr. Verrall sent me two specimens of this rare 'Ay, captured at 

 Lee, Kent, which were the only ones I had seen, until Dr. Schnabl gave me another 

 lately of the same species, which he designated S. bisignata, Zett. Mr. Verrall's 

 specimens, as well as Dr. Schnabl's, have the abdomen marked with two small, in- 

 distinct, triangular spots placed near each other on the second segment, and with 

 two other very faint ones OJi the third segment, while Meigen says that his M. 

 allotalla was unspotted. As my specimens agi'ce very closely with Zetterstedt's 

 description of S. bisignata,* I am inclined to think, with Dr. Schnabl, that they are 

 the same, but as 31. impuncta often has the abdomen spotted, when it becomes the 

 S. demigrans, Zett. ; so I think it highly probable that the former species may 

 likewise often have the abdomen immaculate, when it will agree with Mcigcn's 

 description of M. allotalla, showing that M. allotalla, Meig., and S. bisignata, Zett., 

 are only varieties of the same species. 



M. NIGRICOLA, Fall. 

 This species is rare. I had only seen one British specimen when I published 

 my list, whose habitat was unknown to me ; in July 1887 however, I captured a 

 well-marked example at Baslow, Derbyshire. This little fly closely resembles M. 

 vespertina, Fall., in form and colour, but differs by having yellow legs, the fore 

 femora and tarsi only being black. 



M. SEPABATA, Meig. 

 A few months ago Miss R. Prescott-Decie sent me a Dipteron which seemed to 

 differ from the ordinary specimens of M. separata, and I named it M. grandcBva, 

 Zett. Dr. Schnabl, of Warsaw, also lately forwarded to me both males and females 

 of a fly which he also so labelled. All these specimens closely resembled those of 

 M. separata, only differing by having the fore femora more or less blackened at the 

 base. Zetterstedt, in his description of the female of M. grandcBva (he did not 

 know the male), says the forehead is rather pi-ominent, the basal halves of the fore 



» femora are black, the external transverse veins of the wings are straight, the arista 

 pubescent, &c. 

 The specimens which I had received as M. grandceva agreed with those which 

 I possess of M. separata in all points except in the colour of the fore femora, and 

 on looking over my examples of the latter species (of which I have a good many 



* The abdomen Ixiing .siwttcd, it becomes a SpilotHister.
