1874.] NEW SPECIES OF ERIGONE. 441 



so black as the caput ; the sternum is orange-red ; the legs light 

 yellow-brown, except the femora, which are also orange-red. The 

 hairs on the palpi are more numerous and coarser than in E. 

 directa. 



The eyes are smaller than in E. directa, and indistinct, but are in 

 the same position ; the part of the cephalothorax near the occiput 

 appears to be finely and transversely rugulose, or striated with fine 

 scratch-like lines, visible only with a lens. 



The abdomen is elongate-oval, not very convex above, but project- 

 ing a little over the base of the cephalothorax ; it is of a pale buff- 

 yellow colour, slightly tinged with browu. 



The female resembles the male in colours and general characters ; 

 and the genital aperture, though bearing some resemblance to that 

 of E. directa, is yet decidedly distinct. 



Two adult males and five females of this Spider were contained in 

 Mr. Emerton's collection ; and all were as vividly and distinctly 

 coloured as the example above described. This with the slight differ- 

 ences in form and structure above detailed convince me of its distinct- 

 ness from E. directa. The strong contrast presented by the black 

 and orange cephalothorax and legs with the pale abdomen make it 

 very noticeable.
