# An Essay on the Classification of the Parasitic Hymenoptera of Britain Which Correspond with the Ichneumones Minuti of Linnaeus

An Essay on the Classification of the Parasitic Hymenoptera of Britain Which Correspond with the Ichneumones Minuti of Linnaeus is a Victorian monograph of entomology published in the Entomological Magazine between 1833 and 1838, by the Irish entomologist Alexander Henry Haliday.
The Ichneumones minuti of Linnaeus broadly correspond to the Braconidae and (superfamily Chalcidoidea). Haliday establishes higher level taxa (families) and describes new genera and species. The synoptic tables and descriptions are in Latin. Characters used are (mainly) morphology of the abdomen and thorax, wing venation, number of antennal segments and number of maxillary palpi segments.
The essay begins with I Tabula synoptica generum et subgenerum ichneumonum adscitorum Britanniae Synoptic Table of Genera and Subgenera of Ichneumons Found in Britain (Braconidae). This functions as a dichotomous key.

This series (1811, 1812,1814, 1816) was the first attempt to establish a hierarchy of classification for the Adsciti or Braconidae. Nees worked in close association with Johann Ludwig Christian Gravenhorst, who had in 1807 published a monograph on the Ichneumonidae). Nees uses word familia to signify groups of species within a genus as well as groups of genera. He gave collective names to these groups (Cheloni, Sigalphi, Microgasteres, Agathides, Bracones ,and Bassi).
