Zur Phylogenesis einiger neotropischen Alticiden (Col. Phytophaga)

Summary On the phylogenesis of some neotropical alticids (Col., Phytophaga) Material collected by Dr. Niilo Virkki for cytological purposes was determined by the authors. Their intention is to prove that results obtained by cytological investigation from one side should be identical with those obtained by morphology, ecology and geonemy, and that they may be used as mutual controls.
