sending me specimens of the moth, which he had himself bred from 

 these Pea-eating larvae, which proved to be those of M. brassicir. 



In most of the technical descriptions of this larva to which I have 

 had opportunity to refer, the early colouring is mentioned (that is, if 

 it is noticed at all) as being of some shade of green, but I do not find 

 any details of markings given any more than of the very special and 

 continuous selection of Pea leafage for its food. Tlierefore, as I have 

 long known Mr. Sim to be a careful observer, I have given the above 

 notes as (I believe) an addition to what is commonly accessible re- 

 garding the habits of this very great pest. 



For a remedial measure in this case, probably nothing would act 

 better than hand-picking from the Pea plants ; as a general treatment, 

 turning the chrysalids out to the surface of the ground where they 

 have buried themselves, so that they may be cleared by birds, or be 

 killed by being thrown out of their self-made shelters, is a good plan, 

 and is still more effectual if (in case the labour is worth while) the 

 chrysalids are hand-picked from the ground and destroyed. 



This kind of attack is not often enquired about, but some short 

 notes regarding it are given in my Annual Keports for 1880, 1881, and 

 1882. Also at pp. 28-31 of my ' Manual ' the life-history is given, 

 with means of prevention and remedy, especially for attack to Cabbage, 

 the crop chiefly subject to its attacks. 



PINE. 

 Pine-shoot Tortrix Moth. Retinia buoliana, W. V. 



The attack of this species of Retinia to Pine shoots is stated to be 

 common and generally distributed in Britain ; but I have only once 

 before received enquiries regarding the infestation, and on one other 

 occasion the presence of this species was alluded to by one of my 

 correspondents as occurring near King's Lynn, in Norfolk. 



In this case Mr. E. A. Atmore, F.E.S., mentioned that the little 

 moth R. buolianci caused much injury to Scotch Firs in the neighbour- 

 hood by rendering the shoots sterile, and that the allied species, 

 namely, R. jnnivorana, R. pinicolana, and R. turionana, also caused 

 some little mischief in a similar manner to that of R. buoliana in 

 Scotch Fir. 



In the only instance in which I received specimens of the infesta- 

 tion, a parcel of Scotch Fir shoots, with insects accompanying, were 

 sent me by Mr. E. Gough, Forester to the Duke of Bedford, from the 

 Woods Department, Park Farm Office, Woburn, Bedfordshire. This 

 was early in June, 1895, and from the good supply of characteristically
