Summary
The chromosomal sets of five species ofPerlodidæ (Plecoptera) are given in the present paper. The sexual chromosomes belong to three distinct types:X-O,X 1-X 2,X 1-X 2-X 3. The author shows that these three types are likely derived from the most primitive patternX-Y, by translocation and inversion.
