(on the hinder part of the abdomen) forms a continuous transverse 

 curved line, ending with a blotch at each extremity; no doubt 

 these transverse bars vary in length and strength in different ex- 

 amples : each side has a strong irregular black patch on the middle ; 

 and the underside is dark brown, margined with black : the geni- 

 tal aperture is, like all of this genus, of peculiar structure, and has 

 a prominent epigyne, with several small corneous-looking processes 

 connected with it. 



A single example of this very distinct LinypMa was received 

 from Mr. J. W. Traill, by whom it was found near Dunkeld in 

 1872. 



Family THOMISIDES.-

Xysticus Pavesii, sp. n. PI. XV. fig. 8. 

 Adult male, length rather more than 1^ line. 



In form and structure this very distinct and pretty species is of the 

 ordinary type. 



The cephalothorax is almost round, a little produced and constricted 

 laterally before, and tolerably convex above ; the hinder slope being 

 gradual ; its colour is brownish yellow tinged with orange, with 

 two slightly darker longitudinal bands, one on each side, bearing a 

 broad central longitudinal band, with a pale patch near the middle 

 of it. 



The eyes are on pale yellow-grey tubercles, in the ordinary position, of 

 two parallel curved rows, the curves directed forwards, and the fore- 

 most row the shortest ; the eyes of each row are as nearly as possible 

 equidistant from each other ; the four central eyes form a square, 

 whose foremost side is rather shorter than the rest : the height of the 

 clypeus is half that of the facial space. 



The legs are moderately strong ; those of the first and second pairs are 

 long, much stronger than those of the third and fourth pairs ; their 

 relative length is 2, 1, 4, 3 ; they are furnished with hairs and spines ; 

 the colour of the first two pairs is yellow (tinged with brown), and the 

 fore extremities of the tibial joints are of rather a deeper hue ; the 

 colour of the third and fourth pairs is pale yellow. 



The palpi are short and not very strong ; the cubital and radial joints are 

 about equal in length, the former perhaps a little the longest ; the 

 latter has its fore extremity on the outer side produced into a mode- 

 rately long, not very strong, slightly tapering apophysis, adhering 

 closely to the side of the digital joint, and bifid at its extremity ; also 

 beneath the fore extremity of the radial joint is another moderately 

 long, slightly curved, and obtusely pointed prominent apophysis j the
