We have very great pleasure in adding the name of Mr. 

 Claude Morley 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) ROSE AN M, B. & B., 

 A NEW BKITISH DIPTERON. 



By James E. Collin, 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 pupae of Tortrix pronuhana, 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 roseancB, 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 hairs, scattered in the male, but less numerous and almost in a 

 single row'in the female. Ocellar bristles developed, pointing forwards. 

 Mouth margin not produced, one strong pair of vibrissae placed just 

 above the mouth opening, the smaller oral bristles continued in a row
