together on some of the highlands in this district ; and I 

 have received well-authenticated intelligence, but without 

 specimens, of the capture of several others in the withy-beds 

 between this place and Marazion. I see a statement in some of 

 the daily papers that locusts have appeared in great numbers 

 in the western counties, and have damaged the cabbage and 

 brocoli crops. I suppose the first part of the statement may 

 be correct, but, so far as this neighbourhood is concerned, 

 the second is not. Our brocoli crop and all other crops of 

 a similar nature are suffering most severely from the ravages 

 of a greenish caterpillar, of the species of which I am not 

 informed. These, and not the locusts, are devouring every 

 green herb that grows on the face of West Cornwall. — 

 T/iomas Cornisli ; September 17, 1864. 



[On receiving this information I immediately wrote to Mr. 

 Cornish, begging for a supply of the green caterpillar that 

 was doing so much injury, and was rather surprised to find 

 it the too familiar larva of Pieris Brassicae. On the subject of 

 the locust J incline to say that 1 have never seen a well- 

 authenticated British specimen of Gryllus migratorius. I 

 shall therefore feel extremely obliged for specimens ; should 

 they prove to belong to any other species, I shall have much 

 pleasure in publishing the correct name. — E. Newman.^ 



42. Note on Cynips lignicola. — At the top of Highgate 

 Hill there are two little oak trees side by side, with their 

 branches in contact. One appears to be quite healthy, is 

 covered with acorns, and has no Devonshire galls upon it. 

 The other is sickly, is covered with Devonshire galls {Ciprips 

 lignicola), and has not an acorn upon it. I hope to be able 

 to notice their respective appearance next September. — 

 F. Walker; September 22, 1864. 



43. The Artichoke Gall. — Will you have the goodness to 

 explain the curious substances enclosed, growing, as you see, 

 on an oak-twig, and consisting of a small green nucleus and 

 a scabrous covering, enclosing setaceous segments between 

 the exterior covering and the nucleus ? On opening the 

 crown a maggot rushed out, and, wriggling backwards, hung 

 from my hand suspended by a thread. 1 enclose it in cotton 

 wool. — C. Sei/tnour. 



[The so-called maggot is apparently the larva of a Tortrix, 

 and I believe quite innocent of fabricating the gall : 1 have
