resting to find here and there in this material whole cysts in which
the nuclei were like those described by Paulmier ('99) for _Anasa
tristis_ (plate XIII, fig. 14) as cells which were being transformed to
serve as food for the glowing spermatids (figs. 105, 106). The only
occasional appearance of these cysts seems to me to preclude their being
a special dispensation to furnish the spermatids with nutrition during
their transformation. Their appearance and size make me suspect that
they are giant spermatids due to the failure of one of the
spermatogonial or spermatocyte mitoses. The smaller chromatin body seems
to correspond to that described for the spermatids of _Odontota
dorsalis_.

Euphoria inda (Family Scarabaeidae).

Of _Euphoria inda_ only one male was captured, but the numerous testes
furnished abundant material in desirable stages. The spermatogonial
equatorial plate (fig. 107) contains 20 chromosomes of which the two
smallest (_l_ and _s_) form the unequal pair. The resting spermatogonium
contains a two-lobed plasmosome (fig. 108). The growth stages are
similar to those in _Tenebrio_ in showing no distinct bouquet stage, but
there is a spireme stage in which the heterochromosome pair is clearly
seen (fig. 109). Figure 110 (plate XI) is an early prophase, and figure
111 one in which the unequal pair appears with a tetrad and several
dumb-bell forms. The prophase of the spindle, as in _Odontota_, is much
elongated (fig. 112). In figures 113-116 the small heterochromosome pair
is shown in various positions with reference to the other chromosomes of
the metaphase of the first spermatocyte. Figure 117 shows it more deeply
stained than the others in the equatorial plate. This pair divides in
advance of the others, and the larger and smaller elements are plainly
seen nearer the poles in anaphase than the other univalent chromosomes
(figs. 118-120). Daughter plates of the first spermatocyte are shown in
figure 121, and equatorial plates of the second spermatocyte in figure
123. Figure 122 shows the telophase of the first division with the
spindle for the second division forming. In figures 124 and 125 we have
daughter plates of the two classes of second spermatocytes, showing the
content of the two equal classes of dimorphic spermatozoa, as this was
shown in _Tenebrio_. Figures 126 and 127 are anaphases showing the
division of the heterochromosomes (_l_ and _s_). Figures 128-130 are
early stages in the development
