ABSTRACT
In 1974 White and Jacques requested that the International Commission on Zoological Nomenclature use its plenary powers to suppress the generic name Polygramma Chevrolat, 1837, for the purposes of the Law of Priority, but not for those of the Law of Homonymy, with P. juncta as type-species by monotypy on the Official Index of Rejected and Invalid Generic Names in Zoology. Specimen host records recorded feeding on egg-plant Solanum melongena and Irish potato, Solanum tuberosum but according to Bernon L. dejecta “almost surely will not feed on S. tuberosum or S. melongena.” One of the reasons the popular name “False Colorado potato beetle” has been in literature so many times is due to its confusion with the true Colorado potato beetle. Chittenden feels that L. juncta has literally been driven out by the Colorado potato beetle, suggesting that L. decemlineata ate and destroyed the food source of L. juncta which has a very limited host range.
