I have only seen a dried female specimen, communicated to me 

 by Westring. It appears not to have been described either by Black- 

 wall or Menge, which however it is difficult with certainty to affirm, 

 as the male is unknown. That among Menge's species, which seems 

 most to resemble it in size and colour, is ? of his Mieroneta tessel- 

 lata l ), which however specimens kindly communicated by Menge 

 show to be another species, and = Neriene fusca Blackw. or Erig. 

 simplex Westr. (se that species above, p. 125). The cephalothorax 

 of E. parasitica is highest a little in front of the centre: when seen 

 in profile it is convex, but not in a uniform curve, but somewhat 

 depressed in the middle, where the head — which is rather strongly 

 convex, especially behind — passes into the pars thoracica. The 

 area of the central eyes is double as long as it is broad behind ; the 

 posterior central eyes are small , and the distance between them scar- 

 cely so great as the eye's diameter; the posterior row of eyes is 

 strongly curved forward, and the distance between the posterior la- 

 teral and central eyes double that between the two posterior central 

 eyes, and equal to that between the anterior and posterior central 

 eyes. The two anterior side-eyes are the largest of all; the distance 

 between them and the anterior central eyes is much greater than that 

 between these last , which are very small and near each other. — In 

 the spider, which Menge considers as ? to his Micron, tessellata, the 

 posterior row of eyes, viewed from above, is almost straight, and 

 the distances between these' eyes about equal: the length of the area 

 of the central eyes is not greater than its breadth, the 4 anterior 

 eyes are situated at about equal distances: the patellae have a strong 

 bristle, the somewhat thickened tibiae two such bristles on the upper 

 side {not a coarse bristle also or fine spine on each side, as in e. g. 

 the rather similar Linyphia convexa: in all species of the genus TAny- 

 phia there are one or more spines also on the sides of the tibiae).
