EDITORIAL. 
We have very great pleasure in adding the name of Mr. 
Craupge Mortey to the list of specialists who are good enough to 
advise and assist us in their particular departments of Entomo- 
logy. Mr. Morley, who is the author of ‘The Ichneumons of 
Great Britain,’ and of other works on Hymenoptera, has already 
contributed various instructive and helpful papers to our pages, 
and it is hoped that his closer connection with the magazine 
may be followed by the appearance of many other articles from 
his pen. 
ZENILLIA (MYXEXORISTA) ROSEAN4, B. & B., 
A NEW BRITISH . DIPTERON. 
By James EK. Coun, F.E.S. 
In November last I received from Mr. R. Adkin several 
specimens of the dipteron to which he refers in the subjoined 
note as having been reared from pupe of Tortrix pronubana, Hb. 
They were submitted to Mr. C. J. Wainwright, who has made a 
special study of the Tachinid group to which they clearly belonged, 
and he is of opinion that they are undoubtedly referable to 
Zenillia roseane, B. & B., a species not hitherto recognised as 
British and which may be known by the following characters :— 
A small to moderate sized species of the usual Tachinid appear- 
ance, black with greyish reflections. Face and orbits whitish. Eyes 
sparsely hairy. Frons only slightly produced, at the vertex about one 
quarter the width of the head (female), slightly less in the male; two 
pairs of orbital bristles in the female, none in the male ; frontal bristles 
in a single row extending scarcely beyond the level of the insertion of 
the arista, outside this row for its entire length there are a number of 
fine hairg scattered in the male, but less numerous and almost in a 
single row inthe female. Ocellar bristles developed, pointing forwards. 
Mouth margin not produced, one strong pair of vibrisse placed just 
above the mouth opening, the smaller oral bristles continued in a row
