ARANEIDEA. 101 



The eyes of the anterior row are separated from each other by distinct intervals, that 

 between the centrals being less than that between each and the fore lateral next to it; the 

 posterior row is a little longer than the anterior one. A single row of strong bristles runs 

 longitudinally just below the lateral eyes of the three rows, and the eyes of the middle row 

 are nearer to the anterior than to the posterior row. 



The legs are short, those of the fourth pair are the longest but less strong than those of 

 the first pair, and those of the second pair appear to be a little the shortest : they are furnish- 

 ed with hairs, bristles, and a few spines, with a small claw-tuft beneath the terminal tarsal 

 claws. The colour of the legs is jellow. 



The palpi are similar to the legs in colour, short, slender, and furnished with white hairs. 



Thefalces are short, not very strong, straight, projecting, and of a yellow-brown colour. 



The maxillae and labium are lighter-coloured than the falces. 



The sternum is small, oblong-oval, and similar to the legs in colour. 



The abdomen is of a rather elongate oval form, and of a dull yellow colour, somewhat 

 clouded with reddish yellow-brown on the upper side, and clothed with fine yellowish and 

 grey hairs, with a few dark, slender bristly ones intermixed ; on the fore part is a brown 

 marking consisting of two short parallel lines looped in front, and near the hinder extremity 

 tire three confluent bright red-brown patches. The genital aperture is of a distinctive form. 



It is possible that this may be the female of Menemerus cinctus, but, as the colours and 

 pattern of that species are different, it is best to describe it at present as distinct, until we 

 have other evidence of their identity ; dissimilarity of colours and pattern, as well as of struc- 

 ture, are often found in the sexes of spiders, though prima facie such dissimilarity is proof of 

 specific difference.

126. MENEMERUS DELETES, sp. n. 



Adult female : length 2| lines. 



The form of the cephalothorax is flattish ; it is of a deep yellow-brown colour, darkest on 

 the caput, with an indistinct, ill-defined, brownish-yellow, marginal border, and a still less 

 distinct, longitudinal, median stripe on the thorax. The caput and sides of the cephalothorax 

 are clothed with light-grey hairs ; those on the other parts had probably been rubbed off. 



The ocular area is broader than long ; the length of the anterior row of eyes is slightly 

 shorter than that of the posterior one, and the eyes of the middle row are almost exactly in- 

 termediate between them. The fore central eyes are of a dull mother-of-pearl colour. 



The legs are moderately long and strong ; those of the first pair are the strongest, but 

 not quite so long as the fourth pair, and the second pair are slightly the shortest. They are 

 of a yellow colour, those of the first pair light yellow-brown, and with some short, strong 

 spines in pairs beneath the tibiae and metatarsi ; beneath the terminal tarsal claws is a black 

 claw -tuft. 



The palpi are slender, not very long, and clothed with white hairs. 



The falces are yellow-brown, the maxilla and labium a little paler, and the sternum 

 darker ; the last clothed with coarse, whitish hairs. 



The abdomen is oval, truncate before, pointed behind, and of a pale-yellow colour 

 mottled thickly with whitish cretaceous spots ; on the fore part of the upper side is a small,
