ON NEW AND RARE BRITISH ARACHNIDA. 131 



indicated with fine pale whitish lines, scarcely visible excepting 

 in spirit of wine. The genital aperture is much like that of 

 A. gracilipes, but differs a little. 



Two examples found on Bloxworth Heath, October 14, 

 1913. 



Leptyphantes insignis, sp.n. p. 115. Figs. 4-6. 



Adult male, length 1-1 3th of an inch. 



Cephalothorax longer than broad, obtuse at its fore 

 extremity ; lateral marginal impressions at the junction of 

 the thorax and caput almost obsolete ; marginal profile 

 slightly impressed (or hollow) between the ocular area and 

 the thoracic junction ; colour pale dull yellowish, the margins 

 and normal thoracic segments very faintly indicated by 

 dusky blackish. The height of the clypeus appeared 

 slightly to exceed half that of their facial space. 



The eyes are on black spots, and rather closely grouped in 

 a semi-circle ; they are of moderate size ; those of the 

 posterior row are largest, and form a very slightly curved 

 transverse row, whose convexity is directed forwards. The 

 interval between the central pair is distinctly greater than 

 that between each and the outer eye of the same row, next 

 to it. The eyes of each lateral pair are contiguous and 

 obliquely placed, and seated on a small tubercular prominence ; 

 those of the anterior pair are the smallest, near together, but 

 not quite contiguous, and placed on a largish and tolerably 

 distinct dull blackish spot. The trapezoid formed by the 

 four central eyes is rather longer than broad, and broadest 

 at its hinder side. All are pearly white, excepting the fore- 

 central pair, which are slightly suffused with blackish. 



Legs rather long and slender ; 1, 4, 2, 3, hairs, and spines 

 generally, normal. The spines on the tibiae, especially of the 

 fourth pair, very long. Colour uniform pale yellowish, 

 slightly deeper than that of the CephalotJiorax. 



Palpi moderate in length. The cubital and radial joints 

 short, the latter much the strongest, and has its fore extremity
