(Fig. a is from a specimen taken at Madison, N. J. ; b, g, //, /, from one individual from Charleston, S. C. ; c, e, and f from Raleigh, N. C. ; </, from Mansfield, Ohio. A second male of Type B was taken at Raleigh, N, C., from the same catalpa tree with an individual of Type A.) 1 The enlargement is 3700 diameters —somewhat less than that of the figures in my preceding papers. The figures are all from camera drawings and are not schematized, except that in Fig. I, g, one pair of the chromosomes has been slightly displaced in order to show the ///-chromosomes more clearly. No attempt is made to show details of the achromatic spindles. In all the figures / denotes the large idiochromosome, /, the small one, m the w-chromosome, and s the .y-chromosome. (The latter not to be distinguished from the »/-chromosomes in a and c.).
