278 Annals of the South African Museum. 



Sides ferruginous or ochre 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. 



Immatui'e 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 difficult if we had not the 

 various stages of the male pattern and the characteristic form of 

 appendages as guides.

Thoracic dorsum olivaceous, a broad median band black, this 

 band covering slightly more than the median third of each 

 mesepisteruuni and projecting laterally as two spots, the larger one 

 rectangular at the dorsal end, the smaller one nearly square at the 

 ventral third (in the less mature specimen from Lorenco Marques only 

 these two spots on each side are black, the median baud being but 

 slightly darker in colour than the rest of the mesepisterna). Sides 

 very light greyish passing to olivaceous posteriorly and vent rally, 

 marked with black ; three dots at the humeral suture ; a narrow stripe 

 near the posterior border of the mesepimeron, over about the median 

 third ; a line on the dorsal third of the first lateral suture, bent 

 forward at its upper end ; a line on the dorsal third of the second 

 lateral suture ; two dots on the latero-veutral border of metepimeron.
