ON THE OCCURRENCE OP OLIGOTROPHUS LEMEEI, Kieff., 

 IN ENGLAND. 



BY E. MAUDE ALDERSON, F.E.S., AND EDWAKD CUNNOLD, F.Z.S., F.E.S. 



Dipterists will be interested to learn of the presence of Oligo- 

 trophus lemeei, Kieff., in England. I have not yet been fortunate 

 enough to obtain the imago, which belongs to the Cecidomyidse, but 

 Mr. Edward Connold has identified some galls which I sent him as 

 caused by this species, which he tells me has not been previously 

 recorded for Britain, though known on the Continent since 1890. 

 The galls were found during the latter part of July, on some low 

 shrubs of Wych Elm near Worksop. 



The only description of this gall with which I am acquainted is 

 that given in a recent Paris publication, " Les Zoocecidies dea Plantes 

 d'Europe et du Bassiu de la Mediterranee."* As the description 

 therein is very brief, Mr. Connold has kindly written the following 

 one for me, which will enable collectors to recognise the gall when 

 found.— E. M. A.
