 their larvae in the nostrils of the Red Deer, which are greatly disturbed 

 at the presence of the flies.

 which they are furnished, and work themselves upwards until they

 originality, is the result of a request from the E,ev. E. N. Bloomfield 

 for further information upon the subject of Cepheoiomyia auribarhis, 

 Mg. While endeavouring to comply with Mr. Bloomfield's desire, it

 on the subject of the (Estrincs, which, in the larval state, are parasitic 

 upon deer, it might be of some slight use to British Dipterists to give 

 a brief summary of what is known of such of these interesting forms 

 as are either recognised members of our fauna, or may perhaps yet 

 prove to be so. Unfortunately, I can boast of no acquaintance in the 

 living state with any of the species mentioned, and the only one at

 auribarbis, of which we have a single female from Glenmore Forest, 

 Cairn Gorm Mts., Inverness-shire, taken in June, 1895, by Mr. L. W. 

 Hinxman, and kindly presented by Mr. P. H. Grimshaw, of the 

 Edinburgh Museuui, and four larvge, the story of which is described 

 above by Mr. Bloomfield. Consequently, not only for details of life-
