NOTES ON LIFE-HISTORIKS, LARV^, ETC. 281 



I know nothing of the species beyond the facts to which Dr. 

 Riding refers above. It may be as he suggests, that in a state of 

 nature the hxrvie of B. rohoraria do wait until the leaves are out. 

 My observations lead me to feel that I should be surprised if I learned 

 that they really did so. Perhaps Mr. Hewett can tell us '? — J. W.

^^ ARI ATI N. 



Colour Dimorphism in Xanthia fulvactO (cerago). — The rarity 

 of the orange-tinted specimens of this species appears to be most 

 marked in all districts whence data have been received. In some 

 localities it would appear they hardly occur at all. Thus of 38 

 specimens captured at Montrose and examined by Dr. Gunning, 

 30 were of the typical form (pale lemon with red nrnvkings) =fuIvago, 

 Linn. ; 2 were of the ab. snffusa, Tutt ; and 6 of the ab. flarescens, 

 Esp. Not a single specimen of the deeper tinted colour occurred. 

 Of 46 specimens captured at Morpeth, and examined by Mr. Finlay, 

 26 were of the typical iovm, full- ago, Linn. ; 16 were of the ab. suffusa, 

 Tutt ; and 3 of the ab. flavescens, Esp, ; whilst only one of the 

 deeper tinted form, 2ih, arirantia, occurred. Of 31 specimens bred 

 from larvffi taken at Oxshott, and examined by Mr. Page, 14 were 

 of the typical ionw, ftdvago, Linn. ; 12 were of the ab. snffusa, Tutt ; 

 whilst 4 were of the ab. aurantia, Tutt. Of 12 specimens from the 

 New Forest, examined by Mr, Moberly, 2 were typical fulvago, 

 Linn. ; 4 were ab. suffusa, Tutt ; 4 were ab. aurantia, Tutt ; and 2 

 ab. rirgata, Tutt. Mr. Mober-ly adds : — " The ordinary form in the 

 New Forest, so far as my experience goes, is the orange form with 

 red markings. Occasionally we get the orange form with purple 

 markings, and more frequently the paler form with red markings." 

 Mr. Beadle says : — " X. fulvago is a very common and variable species 

 here ; but until last year I never found the ab. flavescens in any 

 numbers. At Kendal the species did not vary much, being lemon 

 yellow with very distinct dark markings." — J. W. Tutt. Febnianj 

 2m, 1896. 



Variation of Hybernia lkucoph.^aria. — We get in Epping Forest 

 both the forms of H. leucophacaria figured on the plate in last number 

 (see IlcronI iii., p. 115, vol. iv., p. 80). — Ambrose Quail, 167, Brook

SOCIETIES. 



The Entomological Society of London held a meeting on 

 February 19th, 1896. Dr. D. Sharp exhibited preparations of Dijtiscus 

 lattssimus and Cyhister roeselii, to show the so-called secondary wing, 

 noticed by Meinert. He stated that this structure is only a part of 

 the elytron, to which it is extensively attached, and that he considered 

 that it corresponded with the angle at the base of the wing seen in so 

 many insects that fold their front wing against the body. He could 

 not consider that this structure afforded any support to the view that 

 the elytra of beetles correspond with the tegulfe of Hymenoptera 

 rather than with the front wings. He also exhibited specimens of 

 Neuroptera, and pointed out that this secondary wing agreed in position
