YoRKs., near Moorsholm, July, 1922. 



This species is known from Finland and appears to be very 

 distinct from Oligntropluis alopecnri, which we have now noted on both 

 Aloperurus pratensis and A. miinsiiroides (ai/it^atis).

Cecidoiii>/i(lani)ii sp. 



Red larva on lower side of Raspberry {nuhufi idaeua) leaves, crinkling 

 the leaf and causing torsion of the veins especially basally and near 

 the mid- rib, giving the appearance of Erin/dii/iid damage.

 holosteae with creamy-yellow larvae.
