ON NEW AND RARE BRITISH ARACHNIDS. 87 



side, followed towards the spinners by a series of angular bars 

 or chevrons indicated by their intermediate spaces, being 

 clothed with hoary hairs, the general colour of the abdomen 

 being dark yellowish-brown. This pattern might thus well 

 be described as having the chevrons of a hoary colour." 



An adult male received also from Dr. Jackson agreed with 

 the above description, and the palpi are of very character- 

 istic form. (See fig. 3a.) Although as yet a rare and little 

 known species, the present will probably be found not 

 uncommon when properly worked for. 



Titanoeca quadriguttata, Halm. (1831, sub. Theridion). 



Titanoeca quadriguttata, Hahn. -Simon (Arachn. 

 de France I., p. 215). 



Immature male, length 1 l-3rd lines. 



This spider closely resembles an Amaurobius in general form 

 and structure ; the example under consideration appears to 

 be about half the size of an adult of the same sex. The 

 Cephalothorax is dark yellow-brown, and longitudinally 

 striped with black-brown lines ; the caput paler ; the ocular 

 region is clothed with long coarss white adpressed hairs ; 

 viewed in profile the caput is considerably raised above the 

 level of the thorax. 



Eyes in two transverse lines, rather small, and not greatly 

 differing in size ; the posterior row has its slight curve 

 directed backwards, that of the anterior row is directed 

 forwards ; those of each lateral pair are separated from each 

 other, and the four centrals form a square. 



Legs moderate in length and strength ; 1, 4, 2, 3 furnished 

 with hairs only ; no spines ; colour pale dull brownish yellow, 

 more or less of the anterior portion of the joints dark brown, 

 giving them an annulated appearance. The femora are 

 almost or altogether dark coloured, and there is a long 

 conspicuous calamistrum on the metatarsi of the fourth pair. 



Palpi moderately long, undeveloped, but the digital joint 

 of large size. Similar in colour to the legs.
