context_page_description: 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. Haliday establishes higher level taxa and describes new genera and species. The synoptic tables and descriptions are in Latin. Characters used are 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. This functions as a dichotomous key.
  Part II is Excerptae Quedam e Methodo Chalidum Parts of a method and groups of chalcids

  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.

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).

  "Of the Ichneumones of the Second Line, (Ichneumones adsciti, Essenbeck)
  The authors who have treated of the family at large are enumerated and noticed in detail by Professor Gravenhorst, in the Prolegomena to his History of European Ichneumones. It was not till the year 1811 that this supplemental branch was distinguished from the proper Ichneumones, by Doctor Nees von Essenbeck, whose system is more fully unfolded in the ninth volume of the New Series of Transactions, published by the Imperial Academy of the Physical Sciences, and has been followed by modern entomologists with few exceptions . That of Spinola, which Latreille adopted, and has adhered to in his latest works, differs in result as detailed by them from that first mentioned, only as respects the genus Agathis, whose affinity to Bracones is admitted by Latreille himself. But, accurately examined, this method will be found to fail, as the variations of the palpi (on which it is founded) are much more extensive than those it comprehends. That of Von Essenbeck is therefore as superior in certainty as it is in facility of application; while the few Apterous species are, by habit, easily assigned to their proper station in the family. He has, however, employed the principle of Spin
