278 Annah of the South African Museum. 



Sides ferrugiuous or oclire yellow, ventral side whitish ; a narrow 

 and much abbreviated mesepimeral stripe metallic green or blackish, 

 and a very narrow black line on the lateral margin of metasterna, not 

 reaching to the median ventral suture anteriorly and little exceeding 

 the middle of the border posteriorly. Abdomen much as in male, the 

 metallic colour green in younger, coppery or dark bronze in very 

 mature specimens. 



Immature males and females are very similar in colour and 

 markings ; mature individuals show a sexual dimorphism of colour 

 that might make the association of sexes diificult if we had not the 

 various stages of the male pattern and the characteristic form of 

 appendages as guides.
