Family TRICHOGRAMMATIDAE 



By B. D. Burks 



All members of this family are parasites in the eggs of other insects. Their thoracic structures 

 show them to have affinities with the Eulophidae, but they must have diverged from the eulo- 

 phid stem at some remote time in chalcidoid evolution. Since all trichogrammatids have 

 3-segmented tarsi, lack the strigil of the foretibia, have greatly reduced antennae, never have 

 the abdomen petiolate, and the forewing usually bears characteristic lines of cilia, they are wide- 

 ly separated from their nearest relatives in the Eulophidae.
