NOTES AND OBSERVATIONS. 43 



lana, chantana, alboflammana, and umcolorana, twenty-two forms in 

 all. In his communication on p. 1228 Harding says : " It has long 

 been the practice of entomologists at the close of the season to take 

 a journey of nearly a hundred miles to the New Forest in Hamp- 

 shire, that being the most celebrated locality for the capture of this 

 most interesting genus of insects. It now appears that nearly all 

 the species may be taken within twelve miles of London." And 

 again, on p. 1576 : " This pleasing and interesting genus has 

 occurred rather plentifully this season in Hainault Forest. Every 

 known species has been taken, together with numerous varieties, 

 which some few years back would have been made into new species. 

 From the numerous varieties I have seen this season, connecting, 

 as they certainly do, one species with another, I am certain that 

 there are but three, or at most four, species amongst the Button 

 tribe." Hindley makes the interesting observation that he obtained 

 his specimens by beating the hawthorn and hornbeam in shady 

 places. In the following volume of the ' Zoologist,' p. 1789, the late 

 S. Stevens says, referring to these captures : " Last season the Peronea 

 were very abundant ; some thousands were taken at Hainault and 

 Whittlebury Forests." — W. G. Sheldon ; January 5th, 1918. 



Peronea cristana, ab. clarkiana, Sheldon : a correction. — 

 With reference to the form of P. cristana which {antea p. 14) I have 

 named ab. clarkiana — by a printer's error rendered clarhiania — I find 

 that, as this name has been already given to another form by Mr. 

 Webb, it is, in accordance with the laws governing nomenclature, 

 invalid, being homonymous, and therefore a new name is necessary, 

 which may be ab. ochreana. — W. G. Sheldon ; January 21st, 1918. 



ToRTRix piceana, ETC., IN West Surrey. — ^Whilst staying at 

 Hindhead last June I found that Tortrix piceana was to be obtained, 

 apparently not infrequently, judging from the fact that in about an 

 hour I knocked out five examples. Unfortunately, the discovery was 

 only made on the day previous to my departure. Amongst other 

 species observed, T. cinnamoineana and Tmetocera lariciana were 

 common amongst larch, Olethreutes capreana amongst sallow, and 

 Perinephila lancealis amongst hemp agrimony. The larvae of Poly- 

 ploca ridens and Acrobasis tumidclla swarmed in the oak trees. — 

 W. G. Sheldon ; January 2nd, 1918. 



Is Gypsonojia aceriana ever double-brooded? — I am induced 

 to ask this question upon reading Mr. Whittle's record in this month's 

 issue (p. 19) of the capture of this species on so late a date as 

 November 2nd last. Some years ago I found it in perfect condition 

 on October 9th at Forest Hill, Surrey ('Entom.,' xxxviii, p. 281), and 

 on October Ith last I took two here in equally good condition. 

 Assuming that it really is double-brooded at times, under favourable 

 conditions, it would be interesting to learn how the larva feeds. It 

 must, of course, feed in a different manner from the larva that 

 produces the normal brood ; I should imagine it would feed between 

 two spun-together leaves. Aceriana, dealbana, and neglectana are 

 all common in this district, the last being inore local ; but I have 

 never seen any sign of double-broodedness in the two last named.
