Software and results were saved in EXCEL for consequent statistic operation and obtaining chromosome patterns. 4 indexes were chose, such as chromosome karyotype, C-band pattern, chromosome behavior and B chromosome for comparative analyses, and adopted SPSS to reconstruct dendrogram. Combined with studies on insect morphology and insect geography, we made a detailed analysis and speculation on the relationship of taxa concerned. Finally we got the conclusions as follows: 1. The number of chromosomes in grasshoppers of Oedipodiae is 2n 〓=23=22+XO. All chromosomes are telocentric chromosomes. Most of the genome formulas are 3L+6M+2S+X and 3
