Among English representatives of L. griseola there are several 

 specimens in my collection with secondaries of a " creamy strami- 

 neous" colour, whilst among the Japanese examples oi adaucta. But!., 

 are one or two individuals with dark grey secondaries. As regards 

 size, some of my English L. griseola measure 1 inch 7 lines, whereas 

 there are four specimens of L. adaucta which do not exceed 1 inch 

 3 lines. I cannot separate L. adaucta or L. cegrota, Butl., from
