Chromosome Numbers in Cimex

Abstract

A SUB-SPECIES of Cimex, phenotypically intermediate between C. lectularius and C. columbarius and obtained from laboratory white rats, has been found to comprise two forms differing in the number of chromosomes. In most cases the haploid number of autosomes is twenty-four, but in occasional specimens it is sixteen. No variation in phenotype, correlated with this change in number, has been observed, nor is the normal course of meiosis affected.
