 examples of a black form of this species, which may be 

 classified as follows : — 



a. Pitch-black, costa whitish (three females). 



b. Pitch-black, costa whitish on its basal half (male and female). 



c. Pitch-black, metasteruum and hind coxne yellow (male and 

 female). 



d. Entirely pitch-black (one male).
