G, cordicolUs. Chaud., is a female example of G. Gruti, lacking the 

 humeral white line ; one of my female specimens has no median 

 white spots, another has only the apical band left. In the British 

 Museum, I have seen four female examples, two of which had no 

 humeral white line ; two had dark-blue legs, while the legs of the other 

 two "were reddish.
