able projecting ledge from the inferior part of the face; above it is 

 slightly depressed longitudinally; viewed from before, it is at least 

 double as broad as it is high, with the sides somewhat sloping, not 

 quite perpendicular. On both sides, behind the lateral eyes, the head 

 exhibits a deep, oblong fovea or furrow directed backwards, the breadth 

 of which is equal to , or a little greater than, the diameter of a la- 

 teral eye. The interval between the two posterior centre eyes is 

 fully as great as the diameter of those eyes. The anterior row of 

 eyes is straight, its lateral eyes being separated by less than their 

 diameter from the almost contiguous centre eyes; the area of the 

 centre eyes is double as long as it is broad behind. The clypeus is 

 visibly higher than the length of the area of the centre eyes, almost 

 as high as the anterior row of eyes is long. The outer border of 

 the lamina is, at the base, above, elevated into a triangular crest, 

 which rises gradually backwards and is perpendicularly terminated 

 at the posterior extremity; the tibial joint has on the outer side near 

 the apex a little tooth pointing forwards; the bulbus exhibits, on 

 the under side, a very long, almost circularly curved spine. This 

 species very closely resembles E. erythropus Westb., but the cephalic 

 eminence is shorter and the palpi entirely different. On E. erythro- 

 pus see above, p. 120. 



One cT ad. of this species I captured at Travemiiude in Ger- 

 many: I have also received of Mr Cambridge specimens from England.
