oblique ; the legs have the hind tibiae evenly ciliated with bristles of moderate 

 length along the frhole of their externo-posterior surfaces, and also with finer 

 bristles or hairs on their internal and anterior sides ; the pulvilli are small. Common 

 in Yorkshire. 



L. EOEDEUI, Kz. 



This species principally differs from the last by having the dorsum of the thorax 

 and scutellum grey instead of black, and by the former being distinctly striped with 

 three and sometimes five lines ; the wings have the third and fourth longitudinal 

 veins parallel until near their extremities, when they become slightly convergent ; 

 the armature of the hind legs is similar to that of L. ctenocnema. I have captured 

 a few specimens of this little fly near Bradford. 



L. Meadei, Kz. 



This species closely resembles the other two in size and form, the length of them 

 all being about 4 mm. (2 lin.) ; it differs from both L. ctenocnema and L. Roederi, 

 however, by having the hind tibiae ciliated on their externo-posterior surfaces with 

 only a few bristles of irregular lengths along the upper half, instead of with a regular 

 even row down the whole length ; the eyes also have shorter hairs ; the thorax is 

 blackish, with three distinct stripes ; the alulets are fringed with a few black hairs, 

 the third and fourth longitudinal veins are quite parallel, or sometimes slightly di- 

 vergent ; and the pulvilli are larger than in either of the preceding species. Found 

 sparingly near Bradford. 



I know of no decided character by which the females of the above three species 

 can be distinguished from each other ; those which I possess are rather smaller than 

 the males, are grey in colour, have the eyes very slightly and indistinctly pubescent 

 and widely separated, the frontal space occupying about a third of the width of the 

 head. This space contains a black central stripe, bordered on cacli side by a whitish- 

 grey margin, which is about one-third the width of tlie middle stripe. The thorax 

 is light grey, with five pale brown longitudinal lines. The abdomen is grey, with a 

 longitudinal black central stripe, and some transverse marks which are indistinct, 

 and do not reach the edges of the segments. The wings are clear. The legs have 

 the hind tibiae ciliated only with a few spines on the outer sides. 



Before proceeding witli the euumeration of the remainiug species 

 of Anfhomi/iidce, I must make a short digression. The genus Antho- 

 myia, as restricted by Meigen in his supplementary (7th) volume, is 

 so large, even after the species belonging to Ophyra, Homalomyia, and 

 Azelia, which he included, have been abstracted from it, that it is ne- 

 cessary to sub-divide it further. This sub-division has already been 

 attempted by E. Desvoidy, Macquart, and Eondani ; the first author 

 carried it, however, too far, and the groups which the others formed 

 are very artificial and unsatisfactory, so I shall venture to propose a 

 new arrangement. 



In the first place, the pale-legged and pale-bodied species must be
