NATURAL ENEMIES: Microterys fuscicornis
(Howard) parasitizes the leaf form of T. par-
vicornis (= numismaticum) in Maryland. Peck
(1963) and Krombein et al. (1979) listed Coc-
cophagus immaculatus Howard from NY to FL
and AL.
REMARKS: Toumeyella parvicornis is the only
species of Toumeyella in Florida with aggrega-
tions of bilocular pores.

BIOLOGY: Toumeyella pini prefers the outer
tips or new growth of its host, and is seldom
found on large limbs. Immature scales appear in
May in Virginia. It is frequently found in mixed
infestations with T. parvicornis (Williams and
Kosztarab 1972).
