NEW AND RARE BRITISH SPIDERS. 2Q 



Sintula nigrotibialis, sp. n. 

 Adult female, length fths of a line (i-i6th of an inch). 



Cephaiothorax short-oval, slightly hollow-truncate behind, 

 obtusely rounded in front, lateral marginal impressions at the 

 caput slight, but quite perceptible. A slight dip in the profile 

 line at the occiput. Height of clypeus a little less than half 

 of the facial space. Colour dull olive-greenish suffused with 

 blackish, and the normal indentations obscurely marked with 

 dusky blackish lines. The curve of the anterior row is directed 

 forwards, that of the posterior row backwards. 



Eyes of moderate size, sub-equal. Those of each row are in an 

 equally curved line. Those of the posterior row are equally 

 separated by a diameter's interval, the central pair are scarcely, if 

 at all, larger than the laterals. The fore-laterals appear to be 

 rather the largest, and the fore-centrals smallest. These last are 

 separated from each other by a very small but distinct interval, 

 and are more than a diameter's distance from the fore-laterals. 

 The four centrals form a quadrangle as long as broad, but its 

 anterior side much the shortest. 



Legs moderate in length and strength, 4, i, 2, 3 furnished 

 with coarse hairs, of which those beneath the tibiae and femora 

 of the anterior pairs are strongest. A strong erect bristle towards 

 the hinder extremity on the upper side of the tibiae and on the 

 genual joints ; the longest and strongest are on the tibiae of the 

 fourth pair. The meta-tarsi of this pair are much longer than the 

 tarsi. The colour of the legs is a dull yellow, tinged with olive. 

 The tibiae, especially of the first and second pairs, are strongly 

 suffused with dusky black. 



Palpi similar to the legs in colour, radial joint double the 

 length of the cubital, but shorter than the digital. 



Fakes rather long, moderately strong, straight, tapering, 

 similar in colour to the cephalothorax. 



Maxilla very short, strong, directed towards the labium, but 

 their extremities still wide apart, similar to the falces in colour. 



Labitim much broader than high, of a somewhat semi-circular 

 form, its apical margin bent downwards.
