transverse rows the curve of the posterior row is strong and its 

 convexity directed backwards, that of the anterior row slight and 

 the convexity directed forwards. The height of the clypeus is 

 half that of the facial space. 



The legs are rather short, moderately strong, and do not differ 

 very greatly in length 4, i, 2, 3. They are furnished with hairs, 

 a few of a bristly nature, erect on the upper side of the tibiae, 

 and two longitudinal parallel rows, of a stronger kind on the 

 anterior sides of the femora of the first and second pairs. The 

 length of the metatarsi distinctly exceeds that of the tarsi ; but this 

 does not appear to be the case in the male in which they are nearly 

 if not quite of equal length. The genital aperture is simple but of 

 characteristic form, though bearing much resemblance to that of 

 other allied species. 



Three females and two males received from the Rev. E. A. W. 

 Peacock, Lincolnshire, March, 1898.

 HASARIUS NICHOLSONII, sp. n., fig. i. 



Adult male length from 2f to 4 lines. Adult female length 

 3 to 3^ lines. 



Cephalothorax of the male longer than broad, moderately convex, 

 oblong, rounded behind, a little impressed laterally at the ocular 

 area, profile line of the upper side moderately rounded, hinder 

 slope rather steep. Ocular area broader than long, broadest in 

 front, and distinctly in advance of the posterior half of the 

 cephalothorax. Colour, deep shining black-brown, thinly clothed 

 with dark hairs, and with a longitudinal central marking or 

 band, densely clothed with short white hairs, this band is broad 

 and rather abruptly pointed in front, and tapers from the ocular 

 area to about the beginning of the hinder slope. 



Eyes in the normal three transverse rows. Anterior row 

 slightly curved, the convexity of the curve directed forwards ; 

 posterior row distinctly shorter than the anterior ; central row 

 shortest, but its eyes just in a straight line with the centres of the
