Bologna, in 1602 (a reimpression of 1638), and called attention to 

 the numerous quaint illustrations. 



Mr. A, A. W. Buckstone exhibited IJreutJtis eiiphroxyne, an under- 

 side with striated markings, from Heme, Kent; B. selene, one very 

 strongly marked and speckled with black, from Ascot ; Vanessia io, 

 dull brown, bred from Lancashire larvae ; FAlnpia prosapiaria, two 

 of a grey form, bred from Oxshott larvae ; Tephrosia consonana, a 

 melanic form, from Maidstone; Aplecta nehidom var. ro6,so»/ and var. 

 thomsoni, both from Delamere Forest ; Crocallis elintinaria, extremes 

 of light and dark banded forms, bred from Wimbledon; Gonodontis 

 bidentota, melanic forms, bred from Leeds. 



Mr. Bateson exhibited specimens illustrating the forms of the 

 leaf in Primula sinensis. These can all be represented as resulting 

 from the combinations of three pairs of factors, any of which may 

 be present or absent. Three of the forms are known in horticulture 

 as ■palm, fern, and oak, the two last being recessive to the normal 

 palm. Moreover, the edge of the leaf may be smooth, as normally, 

 or crimped, having a great multiplication of minute lobes along the 

 margins, as in other crispated varieties. Fern x Oak gives F^^ palm. 

 By intercrossing, all combinations can be made, which may thus be 

 factorially defined. The normal smooth palm is POS, the fern pOS ; 

 the oak poS ; palm crimped, PUs ; oak crimped, Pes ; etc. In the 

 crimped forms the number of marginal lobes increases in combina- 

 tions containing the old sinensis type of flower, those with stellata 

 flowers having fewer lobes. For example, normal smooth palm has 

 about 120 points; smooth fern, 180; T^aXm cvimT^ed stellata , QSO ; 

 palm crimped sinensis. 1,440. 



Mr. A. W. Mera exhibited a series of Psilnra nwnacha, bred from 

 1914 to 1918 from parents originally taken in Eingwood and North 

 Kent. The melanic tendency being fully maintained to the last, 

 the males were the darker of the sexes as a rule. 



On behalf of Mr. Copeland, Mr. Mera exhibited some fine examples 

 of Catocala nupta with smoky lower wings, taken at Loughton on 

 September 12th, 1918. 



Mr. W. J. Kaye exhibited a pair of the hybrid Sphingid luciani, 

 Denso. The crossing is obtained from pairing Peri/esa elpenor 3 with 

 Pergesa porcellus ^ . The result is an insect decidedly nearer the 

 female parent, porcellus. There are, however, several of the male 

 parent's characteristics, such as large subdorsal black spots on the 

 first abdominal segment ; the strong olive coloured costal area of 

 the forewing, and the heavy black costal area of the hindwing. The
