including their own Rpecies, i.e. they :LPC cannibalistic and at most two
larvae of Chis palasite eiirvive in LL single pod. A4dults emerge in July
or August, but no males Iiuve c v w boen seen. Parnell (1963) considers
that this eulophid lives on another host and only occasionally par-itises
Cantariwiu.
The other parasites of ibrtcttCri?iin are Systnsis en.cyrtoides (Walker)
(Pteromalidae), which in contrast to Aprmtocetus is not cannibalistic
and Inosternma Zycon Walker ( L’latygwteridae).
(b) CEinodiphis. The eggs of this fungus feeder are usually laid singly
near the seeds and only one or two larvae are found in infected pods.
The percentage of infection could not be estimated since t,hroughout
July and Auguet detii~cing pods eject niariy immature larvae. Fully
grown larvae overwinter in the soil and adults emerge in June or July
of the following year. Many Clindiplosis larvae are destroyed by the
predacious Lestodiplosis and are also parasitised by Platyguster sp.
(c) Lestodiplosis. Thc eggs are laid singly at tlie end of July and
throughout August. The majority of larvae are found in pods which
also contain Clinodipkwi.9 on which they feed. However, these active
predators will take any hymeriopterous larvae and pupae within the
pods arid are also cannibalistic. Thus no more than two individuals
develop in a single pod. The larvae overwinter in undehiscod pods and
the adults emerge in the following year.

Six species were found associated with the galls produced by Asphundylin sarothamni, namely the inquiline cecidomyid Trotteria sarotkamni
(Kieffer), three primary hyrnenopterous prasitos of AsphondyEia -
Apostocetus brevicornis Yanzer, Pseudodohccw tbacicu,? (Walker),
Eurytomn dentata Mayr and tho hyperparasits of Aprmkwtus, Toryrnus
