From larvae or pupae in clusters of male catkins of P. pinaster 

 either collected in the Isle of Purbeck, or received from Bournemouth, 

 on various dates in the latter half of May or during June, I have 

 reared the moth in seven separate seasons, but always more or less 

 sparingly. The earliest date of emergence is June 25th (1902), while 

 the latest is July 31st (188S). The imago, which I have never yet 

 met with in nature, is most irregular as to the hour of leaving the 

 pupa. My notes, made on some of the more recently bred moths, 

 show that three in any case, and probably five, did so between ID a.m. 

 and 6 p.m., while five emerged between and 10.30 p.m., and five 

 others appeared between 10.45 p.m. and 8.20 a.m. 



Certain discrepancies are, to my regret, noticeable between my 

 own descriptions of the larva aud its feeding habits and those given 

 by Barrett in Lep. Brit. IsL, xi, 43 (1907), where Pinus pinea is the 

 only food-plant mentioned. These I am quite unable to explain, and 

 can only add that all the batches of larvae that have been in my 

 hands liave been feeding in precisely the same way, and that the 

 various individuals that have been critically examined have shown 

 no variation, except as detailed above. 



SUPPLEMENTARY NOTES. 

 Since the above was in type, I have ascertained from Mr. W. 

 McK.Mr, of Bournemouth, who has kindly sent me from there in 

 various years, nearly all the larvae of E. sylvestrana that have reached 

 me, that, in 1885, he supplied the late Mr. C. G. Barrett with clusters 

 of male catkins of P. pinaster that yielded both this species and also 

 0. hifasciana* Seeing that Barrett {I.e.) gives Pinus pinea (" the 

 stone pine ") as the only known food-plant of E. sylvestrana, it seems 

 obvious that, possibly misled by previous records, he must have 

 mistaken P. pinaster for P. pinea, and one wonders whether others 

 have made the same error, and whether the insect has ever been reared 

 from the latter pine. Wilkinson [Brit. Tort., 221 (1859)] says that 

 the imago appears among Pinus sylvestris, and was first discovered by 

 Messrs. Curtis and Dale, at Bournemouth. He adds that it has since 

 been bred freely by Messrs. Wm. Machin and F. 0. Standish " from 

 the young shoots of that tree [i. e. P. sylvestris — E, R. B.], or of 



* In Ent. Mo. Mag., sxiv. 244 (1888), Barrett records the fact that he bred both species 

 from these "shoots and blossoms of fir " tliat were sent him from Bournemouth by Mr. McRae. 

 It would have been more accurate to have used the expression "flowering slroots," smce he 

 received no shoots from Mr. McRae other than those bearing clusters of male catkins. — E. R. B.
