base, tapering toward the apex, and from the base of which issues 

 a process directed outwards; the distance between the anterior and 

 the posterior centre eyes is almost as great as that between the two 

 posterior centre eyes, and not greater than the diameter of one of 

 these latter eyes. In E. bicuspis (Cambr.) cf the apex of the tibial 

 joint, above, is drawn out into a strong, forward-directed process, 

 tapering towards the extremity and slightly curved downwards; the 

 distance between the anterior and the posterior centre eyes is con- 

 siderably greater than the distance between the two posterior centre 

 eyes, and is at least double as great as the diameter of one of these 

 latter eyes.
