ANNOTATED LIST 



OP 



BRITISH ANTHOMYIin.^.

R. H. MEADl^L 



Reprirded fro7n " The Entomologists Monthly Magazine" Vol xviii. 



Tu the following paper I shall attempt to give a list of the British 

 species comprised in the great Sub-Family of Muscidae named Antho- 

 mgiidce. This group of flies may be distinguished from the more highly 

 developed or typical Muscidcd by the first j^osterior wing-cell being 

 fully open ; the fourth longitudinal vein running direct to the margin 

 of the wing, without being bent upwards towards the third longitu- 

 dinal vein in a curve or angle as in the Tachinida- and Mnscidce. 

 The Anthomyiidce ai'e se])arated from the various groups of smaller or 

 acalyptei-ate Museida' by the alulets or scales being more or less 

 highly developed. 



For the illusti-ation of the characters of some of the genera, and 

 also of distinctive points in new or obscure species, it will be useful 

 To introduce some figures of the wings, and I shall first insert an ex- 

 planatory sketch to enable the -student to understand the names of 

 the veins and cells to which reference is made. The terms which I 

 have adopted are the same as those used by Loew in his introductory 

 chapter on the terminology of Biptera, inserted at the beginning of 

 the first part of his Monographs on the Diptera of North America.
