are nearly as remote in others {M. domestica) as in the female : 

 in most of the species the 4th longitudinal nervure is bent, and 

 takes an oblique direction, uniting with the marginal one at the 

 apex; but in M. Lanio and atramentaria it is united (Meigen 

 says) to the 3rd longitudinal one, and in M. meditahunda it is 

 scarcely angulated (fig. 9). 



Many of the following British species, arranged according 

 to Meigen, I have only seen in the cabinet of Mr. W. Clifton, 

 to whom I am greatly indebted for much valuable information 

 respecting the Muscidae.
