Species of the genus Elachertus (Chalcidoidea) are, with the probable exception of E. scobiciae Erdos, ectoparasites of the larvae of Lepidoptera, and as such are sometimes of economic importance. The five species considered in this paper are E. nigritulus (Zett.), E. geniculatus (Ratz.), E. olivaceus (Thoms.), E. scobiciae, and a new species here described under the name pallidus. Bakke (1955) considered geniculatus as probably synonymous with nigritulus, but reasons for regarding the two as distinct species are presented in this paper. Discussions of a species referred to as nigritulus in papers on forest entomology in fact probably relate to geniculatus. Both nigritulus and pallidus have also been reared from insects of economic significance.
