black legs and yellowish base of the wings. There is a female in 

 the Entomological Club collection. 



7. albitarsis, Mg. This, and the following, are considered the same by 



continental authors, but I agree with Zetterstedt in thinking that 

 albitarsis is well distinguished by its more bluish colour, more pel- 

 lucid wings, smaller size, less pubescence, &c. ; the species are re- 

 markable for their black legs, with the middle joints of the front 

 tarsi yellow, and are distinguished by the almost bare arista from 

 mutabilis. There are about four pairs of albitarsis in the Ento- 

 mological Club collection. 



8. Jlavimana, Mg., is much commoner than the last, occurring in tolera- 



ble abundance about June, mostly in marshy places. 



9. mutabilis, Fin. There is one male in the Entomological Club col- 



lection ; this I refer with considerable doubt to this species, which 

 is distinguished by its black legs, with the middle joints of the 

 front tarsi yellowish, and by its rather small size and pubescent 

 arista. The species should be common in England. 



10. flavicornis, E. This is the first of a group of large, thickly pubes- 



cent species, which have no strong black hairs round the edge of 

 the scutellum ; it is distinguished from the others by the entirely 

 yellow legs of the female, and by the yellowish antenna? in both 

 sexes ; the male is smaller than grossa, with less pubescence, and 

 entirely yellow tibiae ; there are two males and three females in the 

 Entomological Club collection, and Mr. Smith has given me a 

 female captured by him in North Devon. 



11. chrysocoma, Mg., is known by its entirely yellowish pubescence, 

 without the least intermixture of black hairs ; the tibiae have a 

 dark ring round the middle. I possess a male, purchased at Mr. 

 Stevens' rooms in 1868. 



12. grossa, Eln., is distinguished by its large size, very thick pubescence, 



dark antennae, and black pubescence about the tip of the abdomen ; 

 this black pubescence is very much less in the male than in the 

 female. The species is not rare in woods in March. 



13. cMoris, Mg. This is the last of the thickly pubescent species, and 



generally has a few black hairs round the edge of the scutellum, it 

 has much less pubescence than the others, and is distinguished by 

 black hairs on the front, thorax, &c, and by the luteous antennae, 

 and a blackish spot about the middle of the tibiae in the male. I 

 believe it is not rare on Galtha palustris in April.
