Eurytomidae (Chalcidoidea) - male
These are the so-called "seed Chalcids". They are among the few Apocritan groups who have reverted to plant feeding for their brood (Gall Wasps and Bees being the two other large exceptions).
Often treated as a mere subfamily (Eurytominae) of Pteromalids in most recent classifications. Perilampidae are another example.

Chalcidoidea
Something from the parasitoid superfamily Chalcidoidae, see here. Maybe Pteromalidae.
