Vkxational Characters of Four Species of Ceuthemis 

 Tabulation based on ten wings of each species. Figures in 

 tabulation are percentages. The number of cells enclosed by 

 Rspl and ]\Ispl is sometimes uncertain because of indefinite- 

 ness proximally or distally of these sectors, or their lack of 

 definiteness throughout. In such cases the number of cells 

 is indicated in the tabulation as doubtful.
