Monographia Chalciditum

Monographia Chalciditum by Francis Walker, published in two volumes in 1839, was a founding work of entomology, introducing new genera of chalcidoid Hymenoptera later to be ranked as families.

In its preparation Walker used descriptions provided by the Irish entomologist Alexander Henry Haliday.

Two more parts were published in the Annals and Magazine of Natural History under the title Descriptions of British chalcidites.
