Psylla aeruginosa Forst., a British insect. — On June 19th, 1915, by beating 

 oak branches at Shotover, Oxon., I captured a pair of a pale green Psylla which 

 appeared to be P. mali, but on setting them I found that, nnlike this insect, 

 they had black rings on the antennae and black-veined wings. Infortunately 

 I was unable to follow it up at that time, but in July 1910 I again visited the 

 tree and succeeded in obtaining a few male and a number of female examples. 

 Some of these were sent to Mr. J. Edwards, who informs me he has no doubt 

 that they are Psylla aerut/inosa Ftirst., which is an addition to our li.st of 

 Hemijytera-Homoptera. — H. Brittkn, Myrtle View, Windmill lioad,

 where last year the}' were in great abundance. He also made remarks on the 

 lateness of Celastrina aryiolus, the late flowering of the blackthorn, and the scar- 

 city of the larvae of Arctia villica and A. caja. jNIr. Priske noted the fact that 

 Pieris rapae went to rest under the heads of daffodils, thus gaining protection.

 roosting-perches. Mr. Frohawk, a series of aberrations oi Pyrameis utaUtnta,
