a few similar obscure spots in front, the stripes on the genua 

 and tibiee being less distinct. The anterior extremity of each of 

 the femora, genua, and tibiee is marked on the upper side with a 

 whitish yellow spot. Falces dark brown, with a pale patch in 

 the middle of the front of each. Palpi (of the male) darkish 

 brown, radial and digital joints darkest. The radial joint is 

 bent, less strong than the cubital, and its outer extremity is 

 produced into a large bifid apophysis ; the anterior limb of this 

 apophysis is black and obtuse, the posterior, which is also rather 

 beneath, is much the largest and strongest, and of a pale hue ; 

 digital joint large, thickly clothed with hairs, oval, and rather 

 obtusely pointed ; palpal organs large, prominent, simple in 

 structure, and of a very deep brown-black colour. 



Sternum glossy, palo yellow-brown. 



Abdomen of an oblong oval form (in the female more distinctly 

 broadest behind) ; upper part and sides dark chocolate brown, 

 palest in the medial line of the fore part, and marked (chiefly 

 on the sides, and, most conspicuously, on each side of the posterior 

 extremity of the upper part), with white and yellowish spots. 

 Under part dull brownish, mottled with white on the lateral 

 margins. 



The sexes are very similar in colours and markings ; the female, 

 however, has the genua and tibia) more distinctly marked with 

 dark stripes than the male. Although the adults here described 

 are, excepting in one important character — the linear dark 

 stripes on the legs — so exceedingly unlike, in colours and mark- 

 ings, the very young example described (I.e. supra), I am con- 

 vinced that they are of the same species. 



Found near Braeniar, and also in Perthshire. Nearly allied to 

 Philodromus emarginatus (supra, p. 333).
