Estimates are presented for the decay width of the inclusive process U
PSILON(8) --> J/psi + X, where UPSILON(8) is a color hybrid bbgBAR of
the UPSILON(4S) in which the b and bBAR quarks occupy a 1S0 color-octe
t state. Invoking the color evaporation hypothesis, we find that GAMMA
(UPSILON(8) --> J/psi + X) less-than-or-equal-to GAMMA(UPSILON(8) -->
ccgBAR) congruent-to 2.8 keV when the invariant mass of the ccBAR pair
is constrained to lie below the open charm threshold of 2M(D). Suppre
ssion factors due to conversion of the ccBAR pair into J/psi and to mi
xing with the color-singlet state are expected to lead to an observed
rate for UPSILON(10580) --> J/psi + X that is comparable to GAMMA(UPSI
LON(1S) --> J/psi + X) congruent-to 60 eV, and thus consistent with ex
perimental bounds on the non-BBBAR decay modes of the UPSILON(10580).
