86 Falconer : A Neit' Genus and Species of Spider. 



very widely separated as in Thyreostheniiis Sim, are relatively 

 larger and more closely grouped. Its nearest allies are Lop- 

 homma Menge and Pocadicnemis Sim. In Lophomma, however, 

 the eyes are larger and the posterior row in a straight line, the legs 

 longer, the sternal termination wider, the fakes much stronger, 

 more divergent and more attenuated, the tibial spines on 

 IV. never longer than the diameter of the joint, while the male 

 has strong postocular impressions. Pocadicnemis Sim. which 

 has the same long strong pubescence on abdomen and limbs, 

 and the tibial spine on IV. also longer than the diameter of the 

 joint, may be distinguished by the more equidistant eyes in 

 both rows, the longer, stouter legs, with the tarsi III. and 

 IV. much shorter in proportion to the metatarsi III. and IV., 

 and the long rolled exserted spine of the male's palpal organs. 



EBORIA CALIGINOSA sp. nov. 

 Length of male and female each 1.75 mm. 

 Male, Plate I., figs. 1. 3, 4, 5, 6, 7. 



Cephalothorax (tig. I and 4) smooth, dusky brown in 

 colour, suffused with a deeper tinge towards the margins, and 

 along lines converging to the thoracic junction. Towards the 

 middle is a dark triangular marking, the apex of which is 

 directed backwards, and prolonged in a slender line to the 

 posterior margins ; on the hinder slope this line is joined by 

 two others, one on each side, arid the three together form a 

 distinct, symmetrical, trident-shaped mark. A similar line 

 passes from the centre of the base of the triangle to the ocular 

 area, just in front of which there are on it two slender erect 

 hairs, longitudinally placed. 



The Caput is attenuated backwards, and limited by indis- 

 tinct suffused lines behind the lateral eyes. Viewed from above, 

 the pedicle which unites the cephalothorax to the abdomen is 

 ]jartly visible (fig. i). 



The Clypeus is furnished with a number of long, black, 

 unequal, slightly curved bristly hairs, which are very character- 

 istic. 



Falces and Maxillae dull yellow brown, and labium 

 dark brown (fig. 3). 



The Falces axd Maxillae are very sparingly clothed 

 with short hairs ; the latter being also provided on the inferior 

 surface near the external margin at the extremity with a long 

 strong bristle (fig. 3).
