Theridion apicatum, sp. nov. 



Female adult, length If line. 



This very pretty Theridion is closely allied to T. uncinatum (Luc), 

 but, although resembling it in the peculiar form of the abdomen 

 (which has on the hinder part of the upperside a small but prominent 

 conical tuberculiform eminence directed backwards), it differs in 

 colour and some other specific characters. 



The cephalothorax is of a dark yellow-brown colour ; in its form, 

 and also in the size and position of the eyes, it has nothing re- 

 markable about it ; the four central eyes form very nearly a square, 

 those forming its hinder side being rather wider apart than those of 

 the fore side ; those of each lateral pair are contiguous to each other ; 

 the four eyes of the hinder row are about equidistant from each 

 other ; the fore centrals are rather further from each other than each 

 is from the fore lateral on its side ; the clypeus is transversely im- 

 pressed immediately below the eyes, but is prominent at its margin, 

 and its height equals at least two thirds of that of the facial space. 

 The falces are also prominent; they project very nearly in the same 

 plane as the clvpeus, and are of the same colour as the cephalo- 

 thorax, as also are the maxillce, labium, and sternum. 



The legs are rather long, slender, furnished sparingly with hairs, 

 and of a uniform clear pale yellow colour ; the palpi are similar 

 in colour, but are tinged with reddish at the joints ; their relative 

 length is 1, 4, 2, 3. 



The abdomen has a whitish-yellow ground-colour, and is reddish
