individual rearings was very limited. Original descriptions of adult 
females are often vague and different authors emphasize different 
morphological and colorational aspects. Therefore, no attempt was 
made to construct a formal key incorporating adult female characters. 
However, a table of salient female characters has been prepared as 
table 1.
