and has an increase of the pink shaded area. It was taken on the 
hills near Gloucester by Mr. C. G. Clutterbuck. Mr. F. G. Whittle 
announces a species of Vortria new to Britain, Ancylis tineana, taken 
by him at Rannoch last June among Hrica and Vaccinium, It appears 
_ to be common in Central and Northern Europe. 
The Hnt. News for January contains a most interesting article, 
“An unusual Case of Parasitism on Clastoptera obtusa (Hem.), by a 
Dipteron, Drosophila inversa.” The Hemipteron is one which forms 
spittle masses on alder. These masses are frequently found to be 
inhabited not only by the larva of the Hemipteron, but by the larva of 
the Dipteron as well, some lying loose in the mass, but most attached 
to the host by their caudal end. ‘It seems to be parasitic only in so far 
that it utilizes the excess of sap drawn from the plant tissues by 
the spittle insect.”
