This is the same as my Sp. afripes* Stein I find still retains the name of Sp. 

 duplaris for this species,t though he admits that it is not the Sp. duplaris of Zett. ; 

 under these circumstances, his name must also lapse. 



Choetophila teapezina, Zett. 



Stein found that the specimens in Zetterstedt's collection labelled A. irapezina 

 were identical with the Ch. impudica of Eondani. On looking over some 

 AnthomyiidcB, which I received some years ago from Herr Kowarz, I found two 

 labelled A. trapezina, Zett., and two others named Ch. impudica, End. Upon com- 

 paring them together, I at once see that they belong to the same species, so T have 

 no doubt that the names are synonymous. 



Stein found an indistinctly marked specimen of Ch. trapezina in the collection, 

 named A. odontogaster, Zett. This species is, therefore, identical with the others, 

 and the name of odontogaster, as well as that of impudica. End., must sink into 

 synonyms of trapezina. 



Chortophila cineeea, Fin. 

 Stein found a number of difPerent species placed under this name, by both Fallen 

 and Zetterstedt, and the description given by these authors are so imperfect, that it is 

 impossible to identify the species. In my list I included two distinct ones together, 

 the males I subsequently found were those of Phorbia cepetorum, Mde., and the 

 females I now see belong to Ch. trapezina. 



Choetophila steiolata, Fin. 

 Stein found Ch. piidica. End., placed under this name, as well as a male of Fh. 

 trichodactyla, End. ; neither of these will agree with Zetterstedt's description of 

 Ch. striolata, which is not very clear, and does not correspond well with those of 

 Fallen and Meigen, so I think that we must reject Zetterstedt's Ch. striolata 

 altogether. This species, howevei', is a well marked one, and not uncommon in 

 England. I formerly confounded it with Ch. trapezina, to which it bears some 

 resemblance, but Mr. Yerrall pointed out that they were distinct ; the abdomen in 

 Ch. striolata being rather depressed and tapering, while in Ch. trapezina it is sub- 

 cylindrical ; the anal segments of the male are also much smaller and less prominent 

 than in Ch. trapezina, and the abdominal dorsal marks smaller and subtriangular, 

 instead of being subquadrate. Meigen's and Schiner's descriptions are rather im- 

 perfect, but that of Fallen is more characteristic ; he says : " Abdomen canescens 

 convexum, incisuris nigris, linea dorsalis quoque adest e guttis nigris formata." 



Phoebia platuea, Mgn. 



Three males of P. cilicrura, End., with one of P. trapezoides, Zett., were placed 

 under the name of platura in Zetterstedt's collection. 



This species seems involved in a good deal of obscurity. Many years ago Herr 

 Kowarz sent me a specimen of P. cilicrura, marked A. platura, Mgn. I then sup- 

 posed it to be named in mistake, but I now believe that these two species have often 

 been confounded together. The larvse of P. platura are said to have been found in 

 onions, and I have bred numerous specimens of P. cilicrura myself from those bulbs,
