Captain B. S. Curwen exhibited a collection of Zygaenids, made 

 by Signor Querci, chiefly in Italy, including Zi/i/aena eri/thius, Z. 

 rubicundu^t, Z. punctuiii, Z. achille(C, Z. stoechadis, Z. transalpina, Z. 

 ephialtes, Z. lonicerce, Z. oxi/troph, and Z. carniolicn. There were 

 varietal and intermediate forms and local races of considerable 

 interest. 



Mr. Cliftbrd Craufurd exhibited two Limeuitis sibilla ab. semi- 

 ni(irina, and a male aberration of Dnjas papJiia, from New Forest, 

 July nth, 1919. 



Mr. W, Bateson exhibited drawings of flowers borne by plants 

 produced as root-cuttings, which differed from those of the parent 

 plants from which they had been raised. The first case, a Bnurardia, 

 was published in " Jour. Genetics," vi., and subsequently two 

 examples in Pelargonium had been found. These occurrences can 

 be interpreted as shewing that the parent plants are really composed 

 of an outer periclinal layer of one variety covering over an inner 

 core of a different variety. In illustration a wholly green plant of 

 Hoya carnosa was shown still attached to the petiole of a white- 

 skinned variegated leaf from which it had been raised. Whether 

 formed on roots, petioles, or elsewhere, an adventitious bud may 

 thus bring up to the surface the characters borne by the inner core 

 of the plant. It was remarkable that of the few plants which had 

 as yet been tested successfully, three should have given root-cuttings 

 unlike the parent plants. 



Mr. H. Moore exhibited the various forms of Danais chyi/sippns, 

 Lin., and Hypolbmias nimippuH, Lin., and contributed the following 

 notes : — 



" The association of these two species is well known to every 

 entomologist, but perhaps there may be others here to whom an 

 explanation would be acceptable. />. chrysippus is considered the 

 commonest butterfly in the world : the sexes are alike, tawny to 

 deep reddish-brown, with black tips to the forewings, crossed by a
