C. GEKUALIS, Eoild. 



This rare species closely resembles tlic preceding one, from which it only clifPers 

 in some minute points, one of which is that the posterior femora are blackened 

 at their apices, somewhat in the same manner as those of C. geniculata, Fall., of 

 which it is, perhaps, only a Taricty. The only specimen which I have seen 

 belonged to the late Mr. B. Cooke. I have included three other species in my li&t-, 

 viz., C. geniculata, Fall., C. verna, Fab., and C. pedella, Fall., upon the authority of 

 Walker, who records them as British in the "Insecta Britannica :" I have not, 

 however, yet seen an indiginous specimen of either species. 



28. ATHEEIGONA, Eoud. 



Gen. ch. — Eyes bare, remote in botli sexes ; forehead prominent ; 

 anteunse with the third joint prolonged, the arista bare, somewhat 

 geniculated, and having the second segment a little elongated ; palpi 

 short, with dilated extremities ; scales of alulets large, and unequal in 

 size ; abdomen of male short, subcylindrical, and clubbed at the end ; 

 wings with the internal transverse veins, placed near their bases, and 

 opposite to, or in front of, the end of the first branch of the first longi- 

 tudinal vein ; anal vein prolonged, but not reaching the margin of 

 the wing. 



A. YARiA, Meig. 

 The peculiar little fly included in this genus bears some resemblance to a 

 Tacldnid, by the form of the head and the size of the antenna) and alulets ; it is 

 also like a Zisjja, by the shape of the palpi ; it has a yellow abdomen marked by 

 four or six black spots. The description of Anthomyia varia by Walker does not 

 apply to this species, though he makes it synonymous with the A. varia of Meigen. 

 Rare. 



29. MTCOPHAGA, Eond. 



GcBV-osia, Meig., Schin. 



Oen. ch. — Eyes bare, remote in both sexes, but much more so in 

 the females than in the males ; arista plumose ; abdomen oblong and 

 subcylindrical in the male, ovoid and depressed in the female ; alulets 

 with small and equal-sized scales ; wings with the anal veins pro- 

 longed to the margin. 



M. ruNGOBUM, Deg. 



This fly might be placed among the species of JSylemyia, if the eyes of the male 

 were not separated by a widish space. It is the largest species in the Ccenosia group, 

 being often four lines or more (8 or 9 mm.) in length. The arista is furnished with 

 long hairs ; the thorax is grey with yellow slioulders ; the abdomen and legs are 

 yellow, except the tarsi, which are black. Not very common.
