4. I should like to use this occasion to mention and to apologize for an unfortunate error which crept into former publications and to which Kosminsky4 kindly drew attention. Male intersexes always show on their wings a mosaic of female and male parts; this is not usually the case in female intersexes. But when female intersexes are derived from crosses involving the so-called Gifu race as one parent the female wings do have the mosaic character. Photographs were given in Goldschmidt’ and other publications. When later pictures of a whole series of male, female, and Gifu type intersexes were needed for a textbook and for a review, photographs of individual moths were selected from a large number and assembled for plates. In doing this, by mistake a photograph of a high grade male intersex was pasted on to the plate of the Gifu series so that now the same individual appears once as a male intersex and once as a female intersex. (See Goldschmidt’, 1934, p. 61, lower left, and p. 62 No. III.) The individual intended for fig. 11, p. 61, is the one pictured in the book of Goldschmidt’ fig. 46, h. It is unfortunate that this technical error was not discovered, but there is still no doubt that male intersexes and females of the Gifu type can be readily distinguished.
