abdomens having a greyish appearance.

Var. abdomen olivaceous, markings whitish. 
One specimen, Albemarle Island. 
This beautiful species is most nearly allied to H. oaxacensis of 
Keyserling, the figure of which would almost answer for it ;. but the 
description of the coloration does not at all agree with it.
