There is this difference between them, however, that in Hesperotettix the accessory chromosome is the small, univalent element, while in Anabnts it is proportionately very large, causing the tetrad with which it is associated to appear as an appendage at one end. The multiple chromosome of Anabnts is a striking illustration of a fact to which I have often made reference, /. e., to the relation existing between chromosomes and the attached archo- plasmic fibers. /// all tetrad elements the fibers are annectent at.
